Epistemological Beliefs about Physics Learning: The Role of Gender, Grade Level, and Ethnicity Background toward Quality and Inclusive Education
type: item
description: This study explores high school students' epistemological beliefs about physics learning in East Nusa Tenggara (NTT) Province and evaluates the effects of gender, grade level, and ethnicity. Utilizing a descriptive-quantitative survey design, the study involved 390 science students (grades 10–12) across six high schools. Data were gathered via the validated Beliefs and Attitudes Toward Physics and Learning (BAPL) instrument and analyzed using a three-way ANOVA. The overall average BAPL score was . Statistics revealed that gender significantly impacted overall beliefs (F = 3.99, p = 0.05), with females reporting more positive baseline scores (70.00 6.74) than males (68.55 7.34). Grade level also exerted a significant main effect (F = 3.60, p = 0.04), showing more sophisticated views in higher grades. Conversely, the main effect of ethnicity was highly insignificant (F = 0.006, p = 0.94). While no significant overall three-way interaction was found (F = 0.85, p = 0.43), a dimension-specific three-way interaction emerged exclusively within the Relevance of Physics in Everyday Life (RLE) dimension (F = 3.05, p = 0.05). These findings suggest that uniform school systems act as epistemic equalizers across ethnic backgrounds in NTT, though gender-sensitive and context-aware pedagogy remains essential to foster sophisticated physics beliefs.

Transforming Academic Emotions and Critical Thinking Through Augmented Reality in PBL: A Rasch Stacking-Racking Analysis
type: item
description: This study aims to evaluate the effectiveness of the Augmented Reality (AR)-integrated Problem-Based Learning (PBL) model on students' academic emotions and critical thinking skills in the topic of Matter and Its Changes. The primary background for this intervention was the low level of student engagement and the difficulty of visualizing abstract science concepts at SMP Negeri 2 Gorontalo. The research employed a quasi-experimental method with a pretest-posttest control group design involving 124 seventh-grade students divided into experimental (n=62) and control (n=62) groups. Data were collected through academic emotion questionnaires (30 Likert-scale items) and two-tier critical thinking tests (16 items), which were then analyzed using the Rasch Model via stacking and racking techniques to ensure data linearity in logit units. The analysis results indicate that integrating AR into PBL significantly increased students' positive academic emotions, with 70.97% of experimental students showing significant improvement, and accelerated critical thinking ability by 1.28 logits compared to 0.44 logits in the control class (Mann-Whitney U, p < 0.001). These findings confirm that AR's immersive visualization functions as cognitive scaffolding that simultaneously strengthens students' affective engagement and analytical thinking, consistent with the Control-Value Theory framework. This study concludes that AR-PBL is an effective intervention for simultaneously transforming affective and cognitive dimensions in junior high school science learning. The findings underscore the importance of integrating immersive technology into the science curriculum to support deeper conceptual understanding of abstract material.

The Effectiveness of Digital Teaching Materials Based on Cognitive Conflict Integrated with Augmented Reality and Nias Ethnoscience to Improve Critical Thinking in Work and Energy
type: item
description: This study aims to analyze the effectiveness of digital learning materials based on cognitive conflict integrated with Augmented Reality (AR) and Nias ethnoscience in improving students' critical thinking skills in the material of work and energy. The method used was a quasi-experiment with a pretest-posttest control group design. The research sample consisted of two eleventh grade Physics classes at SMA Negeri 1 Gido selected through simple random sampling. The instrument used was an essay test to measure critical thinking skills. The results showed that the average posttest score of the experimental class (75.1) was higher than that of the control class (70.4). Hypothesis testing using Mann-Whitney U resulted in a significance value of 0.039, indicating a significant difference between the two groups. These findings indicate that the developed digital learning materials are effective in improving students' critical thinking skills. This effectiveness is supported by the integration of cognitive conflict that encourages conceptual reconstruction, the use of AR that visualizes abstract concepts, and ethnoscience that links learning to the local cultural context.

Soil Insect Diversity and Community Structure as Bioindicators in the Semi-Arid Ecosystem of Madapangga Nature Park, Indonesia
type: item
description: Soil insects play an important role in ecosystem processes, particularly in organic matter decomposition and nutrient cycling. This study aimed to analyze the composition and diversity structure of soil arthropod communities in Madapangga Nature Park, Bima Regency, West Nusa Tenggara, Indonesia. Field sampling was conducted from June to July 2024 using quadrat sampling and pitfall traps at two observation stations. A total of 629 individuals representing 15 species, 13 families, and 8 orders were collected and identified. The Shannon-Wiener diversity index showed a low-to-moderate diversity level (H′ = 1.005), indicating community imbalance due to the dominance of several taxa. Hymenoptera was the dominant order, with arthropod gracilipes comprising approximately 23% of the total collected individuals. The dominance of this invasive ant species may indicate ecological pressure or habitat disturbance within the study area. Environmental measurements showed slightly acidic soil conditions with pH ranging from 5.5–5.9 and soil temperatures ranging from 25–27°C. These abiotic conditions may influence the distribution and abundance of soil arthropod communities. The findings provide preliminary ecological data for biodiversity monitoring and conservation management in semi-arid conservation ecosystems, particularly in the Madapangga Nature Park area and similar environments in Nusa Tenggara.

Development and Expert Validation of the PjBL-STEAM-IC Model for SOLO-Based Thinking Skills and Environmental Awareness in Coastal Schools
type: item
description: Coastal science learning in Pagimana, Central Sulawesi, has not adequately connected local environmental problems with students’ thinking development and environmental awareness. This study aimed to develop and examine the expert validity of the PjBL-STEAM-IC model, in which IC denotes Innovation and Creativity, for SOLO-based thinking skills and environmental awareness in coastal schools. Using an adapted Borg and Gall research and development procedure, this article reports the needs analysis, hypothetical model design, development of instructional materials and research instruments, expert validation, and Product Revision I. Three validators evaluated the model and its supporting products; their ratings were analysed using Aiken’s V, and their written recommendations were examined descriptively. The developed model comprises six phases linking coastal environmental problems, STEAM-IC project activities, SOLO-based reasoning, and four dimensions of environmental awareness: knowledge, attitude, behaviour, and skills. All validated components were classified as very valid, with Aiken’s V coefficients ranging from 0.902 to 0.961. Expert feedback led to clearer operational syntax, stronger theoretical mapping, more explicit STEAM-IC integration, improved alignment with SOLO-based thinking and environmental awareness, and refinement of the student response questionnaire. The model and its supporting products were therefore considered sufficiently valid to proceed to subsequent classroom field testing.

From Biomass Waste to Functional Iron Oxides: Mechanistic Understanding, Structure Engineering, and Environmental Applications
type: item
description: Biomass-mediated green synthesis of iron oxide nanomaterials has gained increasing attention as a sustainable alternative to conventional chemical methods, offering lower energy requirements, reduced chemical toxicity, and intrinsic surface functionalization. Unlike previous reviews that mainly summarize synthesis routes or environmental applications separately, this review establishes an integrated structure–property–performance framework to systematically correlate biomass chemistry, phase evolution, and functional remediation behavior of iron oxide nanomaterials. A structured scoping review was conducted by analyzing 42 peer-reviewed articles published between 2010 and 2024, selected from major scientific databases using predefined inclusion criteria emphasizing crystalline phase identification, quantitative structural characterization, and measurable environmental performance. Comparative synthesis of the collected data reveals that phytochemical constituents, particularly polyphenols and organic acids, regulate Fe³⁺ reduction, chelation equilibria, nucleation kinetics, and phase selectivity among Fe₃O₄, γ-Fe₂O₃, and α-Fe₂O₃. Fe₃O₄-rich systems exhibited smaller particle sizes (10–30 nm), higher saturation magnetization (30–70 emu g⁻¹), and superior pollutant removal efficiencies (90–99%), while γ-Fe₂O₃ showed moderate magnetic properties (20–50 emu g⁻¹) and α-Fe₂O₃ displayed larger particle sizes (30–60 nm), lower magnetization (<2 emu g⁻¹), but greater thermodynamic stability. Adsorption capacities ranged from 30–250 mg g⁻¹ depending on pollutant type and phase composition. Despite these promising performances, variability in biomass composition, phase instability, and inconsistent testing protocols remain major barriers to reproducibility and scalability. This review provides a quantitative and mechanistic framework to guide rational synthesis design, improve reproducibility, and accelerate scalable deployment of biomass-derived iron oxide nanomaterials for e…

Impact of Plant Growth Promoting Rhizobacteria (PGPR) on Nitrogen Uptake and Yield of Palu Local Shallots
type: item
description: Plant Growth-Promoting Rhizobacteria (PGPR) play an important role in improving soil microbial populations and enhancing plant growth and nutrient uptake. This study aimed to evaluate the effect of different PGPR concentrations on bacterial colony populations, growth performance, biomass production, and nitrogen uptake of Palu Valley shallot plants. The experiment consisted of four treatments: control (F0), PGPR 10 mL (F1), PGPR 15 mL (F2), and PGPR 20 mL (F3). The observed variables included bacterial colony population, number of shallot bulbs, fresh biomass, dry biomass, and nitrogen uptake. The results showed that PGPR application increased the bacterial colony population in soil, with the highest population recorded in treatment F3 (3.90 × 10⁶ CFU g⁻¹ soil). The average number of shallot bulbs increased from 9 bulbs plant⁻¹ in the control to 12 bulbs plant⁻¹ in treatments F2 and F3. Fresh biomass and dry biomass also increased with higher PGPR concentrations, reaching 11.95 g and 2.42 g respectively in F3. Nitrogen uptake showed a gradual increase from 1.61% in the control to 1.69% in F3. These findings indicate that PGPR application improves soil microbial populations, plant growth, biomass accumulation, and nitrogen uptake in Palu Valley shallot plants, with the 20 mL PGPR (F3) treatment providing the most effective results.

Physical and Chemical Characteristics of Soil in the Habitat of Gymnostoma rumphianum (Miq.) L.A.S. Johnson in Tojo Una-Una Regency, Central Sulawesi
type: item
description: Sulawesi, particularly the Wallacea region, has a unique yet extreme ultramafic ecosystem for vegetation growth due to nutrient limitations and high heavy metal concentrations. This study aims to analyze the characteristics of the physical and chemical properties of the soil in the habitat of Gymnostoma rumphianum (Miq.) L.A.S. Johnson in Tojo Una-Una Regency, Central Sulawesi. The study was conducted in Betaua and Podi Villages by dividing the locations based on distance from the river flow. Physical parameters analyzed included bulk density, soil texture, and permeability, while chemical parameters included N, P, K, pH, organic C, C/N ratio, and electrical conductivity (DHL). The results showed that the soil texture in Betaua Village was dominated by sand fractions, while Podi Village was dominated by silt fractions due to the influence of river sedimentation. Chemically, the soil is alkaline (pH 8.05–8.28) with low to very low nitrogen and phosphorus content, but has moderate potassium availability. The presence of G. rumphianum, an actinorhizal plant capable of fixing nitrogen, is a key factor in the adaptation and sustainability of vegetation in this marginal land. This study concludes that despite extreme edaphic constraints, soil-plant interactions and local environmental dynamics such as fluviality significantly determine the structure of the ultramafic habitat in the region.

title: An Analysis of the Needs for Developing a CPS–EIS (Collaborative Problem Solving for Environmental Issue-Based Socio-Scientific Issues) Based Environmental Change E-Module as an Effort to Improve Students' Critical Thinking Skills
description: This study aims to analyze the need for developing an e-module based on Collaborative Problem Solving for Environmental Issue-Based Socio-Scientific Issues (CPS–EIS) on environmental change as an effort to improve students' critical thinking skills. This research employed a descriptive design with a needs analysis approach, conducted in December 2025 at a public high school in Karanganyar, involving 10th-grade students and biology teachers. Data were collected through Likert-scale questionnaires and interviews, then analyzed using percentage techniques and qualitative interpretation. The results indicate that although the level of difficulty of environmental change material was relatively low (42.57%), the current learning process remains less engaging and lacks structured problem-solving activities. Students showed a high need for multimedia integration (76.00%), strong readiness for collaboration (84.28%), and high interest in critical thinking-oriented learning (84.00%). From the teachers’ perspective, there was an absolute need (100%) for e-modules that present real-life environmental cases, facilitate collaboration, provide clear problem-solving steps, and integrate multimedia elements. These findings highlight a gap between existing learning conditions and the expectations of interactive, student-centered, and contextual learning. In conclusion, the development of a CPS–EIS-based e-module is strongly needed as an innovative solution to support meaningful learning, bridge theory and real-world environmental issues, and enhance students’ critical thinking skills in the digital era.

Synergistic Effect of Amino Acids and NPK on Growth Dynamics, Yield Components, and Grain Productivity of Inpari 32 Rice Variety (Oryza sativa L)
type: item
description: Rice productivity improvement is essential to support food security and sustainable agricultural development. This study aimed to evaluate the synergistic effects of amino acids and NPK fertilizer on growth dynamics, yield components, and grain productivity of the Inpari 32 rice variety (Oryza sativa L.). The experiment was conducted in Sukatani Village, Subang Regency, Indonesia, from July to October 2025 using a Randomized Block Design with nine treatment combinations consisting of three amino acid concentrations (5, 10, and 15 mL L⁻¹) and three NPK fertilizer doses (50, 100, and 150 kg ha⁻¹), replicated three times. Observed parameters included plant height, tiller number, leaf area index, productive tillers, panicle number, filled grains per panicle, 1000-grain weight, harvest dry grain yield, and milled dry grain yield. The results showed that the combination of 10 mL L⁻¹ amino acids and 100 kg ha⁻¹ NPK fertilizer produced the highest plant height (74.42 cm), tiller number (26.20 tillers), productive tillers (19.37), filled grains per panicle (126.57 grains), 1000-grain weight (26.50 g), and milled dry grain yield (7.93 kg plot⁻¹). The synergistic interaction between amino acids and NPK improved nutrient uptake efficiency and physiological performance, resulting in higher grain productivity. Therefore, the combined application of amino acids and NPK fertilizer can be recommended as an effective strategy for sustainable rice production.

type: item
description: This study aims to analyze the effects of Android-based learning and learning motivation on the Informatics learning outcomes of tenth-grade students at SMK Negeri 1 Sumatera Barat. Android-based learning is increasingly important in vocational education because it supports the development of digital competencies and independent learning skills required in the digital era. Previous studies have generally examined Android-based learning and learning motivation separately, while evidence regarding their interaction remains limited. This study employed a quasi-experimental method with a 2 × 3 factorial design involving 84 students in experimental and control classes. Data were collected using a learning motivation questionnaire and a learning outcomes test and analyzed through descriptive statistics and Two-Way ANOVA. The results showed that the experimental class achieved a higher mean posttest score (78.61) than the control class (68.33). The N-Gain score was also higher in the experimental class (0.55) than in the control class (0.34). Two-Way ANOVA revealed significant effects of the learning model (F = 32.47, p < 0.05), learning motivation (F = 22.86, p < 0.05), and their interaction (F = 6.43, p < 0.05) on learning outcomes. These findings indicate that Android-based learning is more effective when supported by high student motivation. This study provides empirical evidence for integrating technology-enhanced learning and motivational factors in vocational Informatics education.

type: item
description: Thin-tail sheep is a local genetic resource widely raised by farmers and requires conservation through appropriate breeding programs. This study aimed to characterize quantitative and qualitative traits of thin-tail ewes reared at PT Juara Farm, Bojonegoro. A total of 66 ewes aged 1–4 years were observed, with quantitative traits including body weight, body length, body height, and chest girth, and qualitative traits focusing on tail shape. Data were analyzed descriptively. The results showed that all body measurements increased with age, with body weight ranging from 23.08 ± 3.83 kg in 1 – <2 years to 29.25 ± 3.79 kg in 3–4 years. Similar increasing trends were observed for body length, body height, and chest girth. Three tail shapes were identified: triangular (48.48%), straight (42.42%), and sigmoid (9.10%). The coefficient of variation indicated that body weight had higher variability compared to other traits. In conclusion, thin-tail ewes exhibit age-related increases in body size with moderate phenotypic variability, providing baseline information for breeding and conservation programs.

Optimizing Sustainable Wastewater Treatment: Kinetic and Parametric Study of Methylene Blue Removal Using Electrocoagulation
type: item
description: This study investigates the removal of Methylene Blue (MB) from synthetic wastewater using a batch electrocoagulation (EC) reactor with two pairs of parallel monopolar iron electrodes, directly supporting Sustainable Development Goal 6 (Clean Water and Sanitation). Operational parameters, including initial pH, inter-electrode distance, applied voltage, and electrolysis time, were systematically evaluated. Within 15 minutes of electrolysis, a color removal efficiency of over 80% was achieved at an applied voltage of 10 V and an inter-electrode distance of 5 mm. Treatment efficiency decreased to 60.13% when the inter-electrode distance was widened to 10 mm due to increased cell resistance. Conversely, increasing the voltage from 10 V to 20 V and 30 V significantly enhanced the process efficiency. The MB removal rate was validated using a mass transfer-based kinetic model solved via the 4th-order Runge-Kutta method. The model aligned well with experimental data, displaying a Sum of Squared Errors (SSE) range of 0.09 to 193.57. At an extended electrolysis time of 75 minutes, the average efficiency reached 92.04% across all voltage variations, proving that coagulant saturation overcomes mass transfer limitations.

Chemistry Identity Profiles Across Entry Cohorts Among Prospective Chemistry Teachers: Implications for Quality Education
type: item
description: Chemistry identity shapes students’ engagement and persistence in learning chemistry. This study profiled chemistry identity among Chemistry Education students, examined differences across entry cohorts, and tested gender differences in chemistry identity. A quantitative cross-sectional survey was conducted with 176 students from the Chemistry Education Study Program at Universitas Tanjungpura using the 20-item Measure of Chemistry Identity (MoChI) on a 5-point Likert scale (overall reliability α = 0.91). Overall chemistry identity did not differ significantly across cohorts (p = .755), and no significant cohort differences were found in any MoChI subconstruct. Descriptively, value-related interest was the strongest component (M = 4.21–4.48), whereas feeling-related interest was the next strongest (M = 3.72–3.88). Mastery experiences (M = 3.29–3.49) and verbal persuasion (M = 3.09–3.23) were moderate, while internalized identity was the weakest dimension (M = 2.98–3.41). A Mann–Whitney U test showed a significant gender difference, with male students scoring higher than female students (p = .008, r ≈ .20). These findings suggest that students generally perceive chemistry as valuable, but internalizing a “chemistry person” identity remains less developed and requires more structured mastery experiences, credible recognition, and supportive learning environments for development.

Advancing SDG 4 Quality Education: Needs Analysis and Automated PjBL Essay Assessment Design for Projek IPAS in Vocational High Schools
type: item
description: The implementation of Project-Based Learning (PjBL) in vocational high schools requires authentic descriptive essay assessments, yet manual grading frequently induces severe teacher fatigue and subjectivity. This study aims to analyze teachers' assessment needs and design a conceptual model for automated PjBL essay grading specifically for the Projek IPAS subject. Utilizing the initial phases of the ADDIE research and development framework, this descriptive study employed preliminary teacher interviews, field observations, and literature reviews. The needs analysis revealed a critical demand for an efficient evaluation system to mitigate educators' cognitive load. Consequently, a conceptual architecture integrating Word Count, Similarity Index, and Keyword Matching was designed strictly as an administrative and technical pre-screening mechanism, while the Timestamp parameter was relegated solely to task management. Ultimately, this automated conceptual model is projected to serve as a cognitive offloading mechanism to substantially reduce administrative burdens and potentially mitigate grading bias, empowering science educators to reallocate their energy toward authentic substantive assessment.

Integration of Local Potential in Project-Based Learning: Its Impact on Critical Thinking and Scientific Attitudes of Students of SMAN 1 Darussalam
type: item
description: This study aims to analyze the effectiveness of the implementation of the Project-Based Learning (PjBL) model based on local potential on biotechnology material in improving students' critical thinking skills and scientific attitudes. The study used a quantitative approach with a one-group pretest-posttest design for 35 students. The instruments were a critical thinking test and a scientific attitude observation sheet that had been declared valid and reliable (Cronbach's Alpha = 0.789). The results showed a significant increase in critical thinking skills, with an average pretest score of 17.63 increasing to 37.71 in the posttest, and an N-Gain value of 0.897 (high category). The increase occurred in all indicators, with the highest value in the indicator providing simple explanations (0.9226) and the lowest in the indicator organizing strategies and tactics (0.8723), but all in the high category. Students' scientific attitudes also increased, indicated by an average pretest score of 17.49 to 29.51 in the posttest, with an N-Gain value of 0.808 (high category). The highest improvement was found in the critical thinking indicator (0.93), while the lowest was in the collaboration indicator (0.63). Thus, the local potential-based PjBL model effectively improves students' critical thinking skills and scientific attitudes through contextual and project-based learning.

Affective–Cognitive Disparity in Contextual Science Learning: Evidence from Baduy Local Wisdom
type: item
description: Environmental crises require science education to develop not only environmental awareness but also students’ ability to reason about complex socio-ecological systems. This study aimed to analyze students’ Socio-Ecological Reasoning (SER) and Environmental Attitudes (EA) within contextual science learning based on Baduy local wisdom. A descriptive correlational quantitative approach was employed involving 30 seventh-grade students selected through purposive sampling. Data were collected using an essay-based SER test and a Likert-scale EA questionnaire and analyzed descriptively and inferentially using SPSS. The findings showed that students’ Environmental Attitudes were very high (M = 4.40), while Socio-Ecological Reasoning remained moderate (M = 3.07), indicating an affective–cognitive disparity. Pearson correlation analysis revealed a weak and non-significant relationship between both variables (r = 0.12; p > 0.05). This disparity suggests that contextual learning based on local wisdom effectively strengthens environmental values and awareness but has not fully facilitated systems thinking and higher-order reasoning skills, possibly because learning practices still emphasize value internalization more than analytical exploration. Therefore, science learning should integrate phenomenon-based and systems-oriented approaches that explicitly connect local wisdom with scientific inquiry to strengthen both affective and cognitive domains in sustainability-oriented education.

Bridging the Gap in Abstract Biology Concepts: A Needs Analysis for STEM-Integrated Argument-Driven Inquiry (ADI) Photosynthesis Learning
type: item
description: This study aims to analyze teachers' needs for the development of photosynthesis learning based on Argument-Driven Inquiry (ADI) integrated with the Science, Technology, Engineering, and Mathematics (STEM) approach as the basis for developing learning tools. The study was conducted at the needs analysis stage within the Design-Based Research (DBR) framework using a mixed methods approach with a sequential explanatory design. Quantitative data were obtained through a survey of 33 high school biology teachers in Lampung Province using a Guttman scale-based questionnaire, while qualitative data were obtained through in-depth interviews with three biology teachers. The results showed that 66.7% of teachers were not familiar with the ADI model and 54.5% had not implemented the STEM approach in learning. 90.9% of teachers had never used STEM-integrated ADI-based student worksheets, and 100% of teachers had never applied it to photosynthesis material. In addition, 75.7% of teachers had not measured critical thinking skills and 87.8% had not systematically measured collaboration skills. Interview results revealed that teachers still experience difficulties in understanding the implementation of ADI, integrating STEM in learning, developing appropriate learning tools, and facing obstacles such as the abstract nature of photosynthesis material, time constraints, and limited laboratory facilities. Based on these findings, it is recommended to develop a photosynthesis student worksheet based on STEM-integrated ADI equipped with critical thinking and collaboration assessment instruments to support more meaningful biology learning and oriented towards 21st-century skills.

Enhancing Educational Quality Through the P4 Budgeting Model Based on BAA: A SWOT Perspective
type: item
description: Financial management plays a crucial role in improving educational quality; however, many educational foundations still struggle to integrate budgeting, accounting, and auditing into a comprehensive financial management framework. Previous studies have generally examined these functions separately, creating a research gap regarding the effectiveness of an integrated model in supporting educational quality and institutional sustainability. This study aims to analyze the implementation of the integrated P4–Budgeting, Accounting, and Auditing (P4-BAA) model at the Almuslim Peusangan Foundation and evaluate its contribution to educational quality improvement. This study employed a qualitative case study approach. Data were collected through semi-structured interviews with 15 purposively selected informants, including foundation leaders, financial managers, school principals, and administrative staff. Additional data were obtained through document analysis and direct observation. Data were analyzed using thematic analysis supported by NVivo software through coding, categorization, theme development, and triangulation. The findings show that the P4-BAA model strengthened financial planning, accountability, and transparency across educational units. Key strengths identified include institutional reputation, affordable tuition fees, and government support, while major challenges involve limited infrastructure, inadequate teacher qualifications, and unstable funding sources. The model improved budget allocation, stakeholder participation, financial reporting, and monitoring mechanisms, leading to more efficient resource utilization and stronger support for teacher development programs. The study concludes that the P4-BAA model provides a practical framework for enhancing financial governance and sustaining continuous improvements in educational quality.

Electronic Nose-Based Classification of Breath Odor in Fasting and Non-Fasting Individuals Using Principal Component Analysis
type: item
description: Breath odor contains volatile compounds that can reflect the body’s metabolic condition, including those associated with fasting. This study aims to classify breath odor patterns in fasting and non-fasting individuals using an electronic nose (e-nose) combined with the Principal Component Analysis (PCA) method. The e-nose system was developed using an array of five MQ gas sensors (MQ-2, MQ-3, MQ-4, MQ-5, and MQ-6) to detect breath samples from 100 respondents, consisting of 50 fasting and 50 non-fasting individuals. The sensor responses were recorded and analyzed using PCA for dimensionality reduction and data pattern visualization. The results show that the first two principal components account for 81.2% of the total data variance, with contributions of 56.1% from PC1 and 25.1% from PC2. The PCA score plot demonstrates a relatively clear separation between the breath odor patterns of the fasting and non-fasting groups. These findings indicate that the developed e-nose system has potential as a rapid and non-invasive method for breath-based classification.

Assessing the Integration of Environmental Management Systems and Green Supply Chain Management for Sustainable Supply Chains: A Green SCOR Gap Analysis
type: item
description: Environmental Management Systems (EMS) have been widely implemented to improve organizational environmental performance; however, their integration with Green Supply Chain Management (GSCM) remains limited, particularly in the seafood processing industry. This study aims to evaluate the gap between operational-level EMS implementation and integrated GSCM practices at PT. IAMBEU Mina Utama while identifying priority improvement areas to strengthen sustainable supply chain performance. A quantitative-evaluative case study approach was employed using the Green Supply Chain Operations Reference (Green SCOR) framework covering the Plan, Source, Make, Deliver, and Return processes. Data were collected through Likert-scale questionnaires, interviews, field observations, and document analysis. Gap analysis and priority assessment based on environmental and operational impacts were applied to determine critical Key Performance Indicators (KPIs). The results show that EMS implementation (4.20) exceeds GSCM implementation (3.89), indicating a moderate integration gap. The largest gaps were identified in the Return, Deliver, and Plan processes, while priority KPIs include waste management monitoring, circular economy implementation, supplier environmental evaluation, transportation emission monitoring, energy efficiency, and production waste management. The findings indicate that although the company has established a strong internal environmental management system, sustainability practices have not been fully integrated across the supply chain. This study contributes to the development of EMS–GSCM integration using the Green SCOR framework and provides practical recommendations to support sustainable supply chain performance in line with the Sustainable Development Goals, particularly SDG 12 (Responsible Consumption and Production).

The Impact of Land Use on Flood Management: A Case Study of the Banjir Kanal Barat River in Semarang with HEC-RAS
type: item
description: Urban flooding is influenced by land use change, rainfall characteristics, river conveyance capacity, and downstream tidal conditions. This study evaluates the effect of land use conditions on hydrological response, flood inundation, and structural flood control performance using hydrological analysis and HEC-RAS modeling. The 2025 observed land use condition was classified using Landsat 9 imagery and supervised classification, while the 2031 scenario was based on the Semarang City Spatial Plan 2011–2031. The classification produced an overall accuracy of 85.42% with a Kappa coefficient of 0.83. The runoff coefficient increased from 0.41 in 2025 to 0.46 in 2031. The Nakayasu Synthetic Unit Hydrograph method estimated that the 25-year design flood discharge increased from 111.52 m³/s to 139.09 m³/s. HEC-RAS 1D/2D coupled unsteady flow simulation under the HWL condition showed that inundation increased from 12.21 ha to 17.24 ha. River normalization and levee construction improved channel conveyance capacity and reduced overflow potential in critical segments. These results indicate that integrating land use control and structural flood mitigation can support sustainable urban flood management.

Integrating Augmented Reality Based Comics into Chemical Bonding Instruction to Enhance Students’ Thinking Skills
type: item
description: This study aims to investigate the effectiveness of integrating Augmented Reality (AR)-based comics into chemical bonding instruction to enhance students’ critical thinking skills. A quasi-experimental design with a non-equivalent control group was employed, involving 40 eleventh-grade students divided into an experimental group and a control group. The experimental group was taught using AR-based comics within a project-based learning framework, while the control group received conventional instruction without AR support. Data were collected through essay tests, observation sheets, and documentation, and analyzed using descriptive statistics, N-gain, and an independent sample t-test. The results indicate that the experimental group achieved a higher post-test mean score (75.75) compared to the control group (65.30). The N-gain score of the experimental group (0.49) was categorized as moderate, exceeding that of the control group (0.29), which was classified as low. Statistical analysis revealed a significant difference between the two groups (p < 0.05). These findings suggest that the integration of AR-based comics effectively enhances students’ critical thinking skills by facilitating visualization, engagement, and conceptual understanding. Therefore, this approach can serve as an innovative instructional strategy to improve the quality of chemistry learning.

An Intelligent Curriculum Management and Career Development Framework Integrating AI and Competency Standards in TVET
type: item
description: The persistent misalignment between curriculum design, competency standards, and evolving industry requirements remains a critical challenge in Technical and Vocational Education and Training (TVET). Existing curriculum practices are largely static and insufficiently integrated with structured career pathways, resulting in skill mismatches and limited workforce readiness. This study proposes an intelligent curriculum management and career development framework integrating competency standards with AI-enabled decision support. A Design Science Research (DSR) methodology was employed through problem identification, framework design, demonstration, and evaluation. The framework was validated using a three-round Delphi study with TVET and curriculum experts and an empirical case study in an Indonesian TVET institution offering Information and Communication Technology (ICT) programmes based on curriculum documents and SKKNI competency standards. Performance was evaluated using alignment accuracy, relevance, and usability indicators. The results show that curriculum–competency alignment accuracy improved from **68.40%** to **91.20%**, while the framework identified four missing competencies and three redundant curriculum units. Career pathways aligned with industry roles achieved expert consensus exceeding **85.00%**. The proposed framework provides an adaptive, AI-enabled approach for data-driven curriculum governance, competency alignment, and career pathway planning, offering a replicable model for competency-based curriculum development in TVET

The Effect of Arabica Coffee Extract (Coffea arabica L.) on the Expression of Inflammatory Biomarkers and Histopathological Features of the Liver-Pancreas in Alloxan-Induced Diabetic Mice
type: item
description: Diabetes mellitus is a chronic metabolic disorder characterized by persistent hyperglycemia, oxidative stress, inflammation, and organ damage, particularly in the liver and pancreas. This study aimed to evaluate the antidiabetic and hepatoprotective effects of Arabica coffee extract (Coffea arabica L.) in alloxan-induced diabetic mice. Thirty male mice were divided into five groups consisting of a negative control, a positive control treated with glibenclamide, and three treatment groups receiving Arabica coffee extract at concentrations of 50%, 75%, and 100% for 21 days. Chlorogenic acid content was analyzed using High-Performance Liquid Chromatography (HPLC), while blood glucose levels and liver histopathology were assessed after treatment. The results showed that chlorogenic acid content reached 20.8% in the tubruk extract and 16.9% in the macerated extract. Administration of Arabica coffee extract significantly reduced blood glucose levels, with the highest reduction observed in the 100% extract group (65% on day 14 and 62% on day 21). Histopathological examination revealed improvement in liver tissue architecture, characterized by reduced parenchymatous degeneration, hydropic degeneration, and necrosis compared with the negative control group. These findings suggest that Arabica coffee extract possesses antihyperglycemic and hepatoprotective activities and may serve as a promising natural therapeutic agent for diabetes mellitus management

Game Based Learning in The Context of Physical Education in Indonesia
type: item
description: This study investigates the integration of Game-Based Learning (GBL) into physical education (PE) in Indonesia as an innovative pedagogical approach to enhance student engagement, motivation, and awareness of healthy lifestyles. GBL goes beyond standard teaching approaches by encouraging creativity, teamwork, and problem-solving abilities that are important for future difficulties. A quasi-experimental design was used with students from high schools who were split into an experimental group and a control group. The experimental group took part in physical education classes that included GBL techniques, whereas the control group received traditional teaching. Information was gathered through questionnaires about motivation and classroom observations. The quantitative data was evaluated using statistical comparison methods, while the observational results were utilized to enhance the understanding of student actions and involvement. The results showed that students in the GBL group exhibited greater motivation, engagement, and active involvement compared to those in the control group. Classroom observations showed increased collaboration, enthusiasm, and involvement in learning activities among students exposed to GBL. Furthermore, students in the experimental group reported greater awareness of the importance of physical activity and healthy lifestyle practices. The integration of GBL in PE positively influenced student motivation, engagement, and health-related awareness. Although its implementation requires careful planning, adequate resources, and institutional support, GBL offers a promising approach for improving learning experiences and promoting holistic student development in Indonesian physical education settings

type: item
description: To face global challenges, students need to be equipped with Higher-Order Thinking Skills (HOTS). This study aimed at analyzing the positive contributes of the Physics Education and Technology (PhET)-aided Blended-Problem-Based Learning Rotation (BPBLR) model in improving HOTS and describing student responses to the PhET-aided BPBLR model. This study involved 98 seventh grade students in Singaraja who were spread across 3 experimental groups, namely 31, 33, 34, and without control group. This research design was a pre-test and post-test group design. The collected data were analyzed using paired-test, normalized gain (N-gain), and ANOVA. The results of the Paired-Test showed that there was a significant difference in students' HOTS achievement with the PhET-aided BPBLR Model between pretest and posttest for three groups at p < 0.05. The average N-gain HOTS values in each group are: 0.46, 0.45, and 0.46, which are in the moderate category. The ANOVA test results show that the average N-gain values of the three groups is consistent at p < 0.05. Student responses are in very high category. Thus, the use of the PhET-aided BPBLR model contributes positively to improve students' HOTS, and student responses are in very high category.

Carrying Capacity Based on Environmental Services for Food Supply in Talaga City
type: item
description: Environmental Carrying Capacity (ECC) for food supply is the ability of the environment to support population activities through a comparison between the need and availability of food energy. This research aims to provide initial data related to the spatial distribution of ECC for food supply in Talaga Jaya, Telaga, Telaga Biru and Tilango Sub-Districts as part of the city of Talaga and the general conditions of their status descriptions. The Environmental Service Performance Index (ESPI) of the parameters of Landscape, Natural Vegetation and Land Cover was used as a factor in distributing the availability of food energy. Land class and roads distributed population density and food energy needs. The results of the research were analyzed spatially using a supply-demand approach on a grid scale of 0.1 km x 0.1 km. The results found that the spatial distribution of ECC for food supply was in deficit status of 20.03 km2 (11.11%), balanced at 120.86 km2 (67.02%) and surplus at 39.45 km2 (21.88%). Descriptively, the deficit area cannot be covered by the surplus area if there is an energy flow because the high food energy requirement is 64.7 billion kcal/year, while the availability of food energy is only 51.4 billion kcal/year. Thus, the research area has passed the peak of its population growth and is only able to meet the food energy demand for 79.4% of its population. In this case, the government can promote agricultural commodity intensification and diversification policies to meet domestic food energy needs.

Curriculum Construction of Traditional Islamic Boarding Schools in Padang Lawas Regency, North Sumatra Province
type: item
description: This study examines the curriculum of traditional Islamic boarding schools (pesantren) in Padang Lawas Regency, North Sumatra, Indonesia, within the context of ongoing efforts to balance classical Islamic educational traditions with contemporary educational demands. The objectives of this research are to analyze: (1) the current condition of the traditional pesantren curriculum, (2) the obstacles encountered in its implementation, and (3) the construction of the curriculum within learning practices. This research employed a qualitative field research approach conducted directly in traditional pesantren across Padang Lawas Regency. The study involved 18 traditional Islamic boarding schools as the research population. Data were collected through observations and in-depth interviews with key stakeholders and were analyzed using qualitative data analysis techniques to generate a comprehensive understanding of curriculum implementation and development. The findings indicate that the traditional pesantren curriculum primarily consists of learning materials, classical Islamic texts (kitab kuning), instructional methods, and evaluation systems. The curriculum is predominantly oriented toward Islamic sciences, reflecting the historical and religious identity of traditional pesantren. However, several challenges were identified, including unsystematic curriculum planning, limited diversity in teaching methods, inadequate human resource competencies, insufficient educational facilities and infrastructure, non-standardized evaluation mechanisms, low adaptability to contemporary educational developments, and management systems that remain largely traditional. The study further reveals that curriculum construction in these pesantren has gradually evolved through the integration of classical Islamic studies with general education, science and technology, and vocational competencies such as entrepreneurship. Despite these developments, Islamic studies continue to serve as the centr…

Toward a Pedagogically Driven Framework for Designing a Socioscientific Inquiry-Based Learning (SSIBL) Digital Platform
type: item
description: Socioscientific Inquiry-Based Learning (SSIBL) requires instructional continuity across contextual exploration, scientific inquiry, evidence construction, argumentation, and assessment. However, existing digital learning environments often support these activities in isolation, resulting in fragmented pedagogical processes. This study proposes a pedagogically driven framework for designing a Socioscientific Inquiry-Based Learning (SSIBL) digital platform through the systematic identification of instructional needs, synthesis of cross-phase instructional functions, derivation of system-level design requirements, and development of an architectural framework. A design-oriented requirement elicitation approach was employed involving 45 senior high school students and six physics teachers. Data were collected using structured questionnaires covering six phases of the SSIBL workflow and analyzed through descriptive analysis, cross-phase pattern identification, instructional function synthesis, requirement translation, and architectural framework development. The findings revealed consistently high instructional needs across all SSIBL phases and identified four cross-phase instructional functions: Epistemic Structuring, Evidence Construction, Deliberative Anchoring, and Orchestration Visibility. These functions informed the derivation of system-level design requirements and the development of an architectural framework that preserves instructional continuity throughout SSIBL. The study contributes a transparent pedagogically driven framework that bridges instructional theory and educational technology design, providing a conceptual foundation for future platform development and design-based research.

The Influence of Emotional Intelligence, Learning Independence, and Learning Motivation on Science Learning Outcomes of Junior High School Students in State Schools
type: item
description: This study examined the direct and indirect effects of emotional intelligence and independent learning on science learning outcomes through learning motivation among public junior high school students in Kendari. The study employed a quantitative ex post facto design. The population consisted of all public junior high school students in Kendari City during the 2025/2026 academic year. A sample of 194 eighth-grade students from six public junior high schools was selected using proportional random sampling. Data were collected through Likert-scale questionnaires measuring emotional intelligence, independent learning, and learning motivation, while science learning outcomes were obtained from end-of-semester summative assessment scores. Data were analyzed using descriptive statistics and path analysis. The descriptive findings showed that students’ emotional intelligence, independent learning, and learning motivation were generally at a moderate level, whereas science learning outcomes were categorized as high. Path analysis revealed that emotional intelligence did not significantly affect learning motivation (p = 0.113). In contrast, independent learning had a significant positive effect on learning motivation (β = 0.766). Regarding science learning outcomes, neither emotional intelligence (β = −0.027) nor independent learning (β = 0.129) showed significant direct effects. However, learning motivation significantly influenced science learning outcomes (β = 0.352). The indirect effect of emotional intelligence on learning outcomes through motivation was 0.040, while the indirect effect of independent learning through motivation was 0.270. These results indicate that learning motivation plays a key mediating role in enhancing science achievement. Overall, independent learning and learning motivation contribute more substantially to students’ science learning outcomes than emotional intelligence among public junior high school students in Kendari.

Ecological index of gastropods in the Tananan River, Mamasa Regency
type: item
description: Research on gastropod ecological indices is important for determining ecosystem stability. Previous research only focused on the abundance of gastropods. The purpose of this study was to analyze the diversity index (H'), evenness index (J'), and dominance index (C) of gastropods in the Tananan River, the research location. The method used included transect and plot sampling at two observation stations, with random sampling. Station A had a sandy substrate, and Station B had a rocky substrate, close to residential areas. Species identification was carried out morphologically, and the data were analyzed using the Shannon-Wiener, Pielou, and Simpson ecological indices. The results showed that gastropod diversity was in the moderate category (H’ = 1,785 – 2,265), evenness values (J’ = 0,893 – 0,975) indicated an even distribution of species, and no specific species were dominant (C = 0,213 – 0,318). These findings indicate a moderate ecosystem condition. Local communities utilize gastropods, particularly Pila ampulacea and Pomacea canaliculata, as side dishes. The processing is still simple and adds to the uniqueness of local cuisine. In conclusion, gastropod ecological indices can be effective biological indicators of ecosystem health. The use of gastropods for public consumption requires further research due to the discovery of Indoplanorbis exustus in the river.

Integrating Islamic Psychology and Developmental Neuroscience in Early Childhood Islamic Education: A Holistic Fitrah-Based Approach
type: item
description: This study aims to examine the integration of Islamic psychology and developmental neuroscience in early childhood Islamic education through a holistic fitrah-based approach. A qualitative field research design was employed in Raudhatul Athfal institutions in Batam City, involving teachers, principals, and parents. Data were collected through observation, in-depth interviews, and documentation, and analyzed using an interactive model. The findings indicate that Islamic psychological principles are implemented primarily through value internalization and behavioral habituation rather than explicit theoretical instruction. Learning practices emphasize the balanced development of cognitive, emotional, social, and spiritual domains, reflecting a holistic approach aligned with children’s innate disposition (fitrah). These practices are consistent with neuroscience perspectives highlighting the importance of early experiences and environmental stimulation in shaping development. However, several challenges were identified, including limited conceptual understanding among educators, lack of interdisciplinary training, absence of standardized assessment tools, and variation across institutions. The study concludes that a more structured and theoretically grounded model is needed to strengthen the integration of Islamic psychology and developmental science in early childhood education.

Development of Quality Criteria and Proposed Specification Limits for Moringa Leaf Powder Through an Integrated Stakeholder and Evidence-Based Approach
type: item
description: The absence of quality standards for moringa leaf powder has caused product variability, limiting consistency, competitiveness, and industrial use. This study developed quality criteria using the FACTS framework, integrating stakeholder priorities (via Exponential Comparison Method across 24 participants) with laboratory characterization of samples from five Indonesian regions. Stakeholders prioritized food safety, sensory quality, and nutritional consistency. However, food safety parameters were excluded as they are already regulated by Indonesian Food and Drug Authority (BPOM). Laboratory data revealed high variability in fineness (CV = 28.83%) and acid-insoluble ash (CV = 52.67%). Benchmarking against Kenya Standard KS 2848:2019 confirmed compliance for moisture and acid-insoluble ash, while fineness, ash, protein, and color required local specifications. Using Adopt–Adapt–Originate, acid insoluble ash was adopted (≤ 0.5%); moisture and fineness adapted; and ash, protein, and color originated. Stakeholder expectations (protein ≥ 27%; moisture ≤ 8%) exceeded empirical thresholds (≥ 23%; ≤ 10%), resolved through inclusive limits supporting a future tiered system. Proposed specifications, i.e. color (green to bright green), moisture (≤ 10%), ash (≤ 13%), acid-insoluble ash (≤ 0.5%), protein (≥ 23%), and fineness (≥ 80% passing 100-mesh) provide a scientific foundation for moringa powder standard in national level.

Integrating STEM and Deep Learning in Renewable Energy Learning to Foster Elementary Students’ Scientific Literacy
type: item
description: This study examined the implementation of STEM-based Deep Learning in fostering elementary school students’ scientific literacy on the topic of renewable energy. A quantitative approach with a one-group pretest-posttest design was employed. The participants were 29 sixth-grade students from an elementary school in East Jakarta. Data were collected using a 20-item scientific literacy test covering conceptual and contextual understanding of renewable energy and were analyzed using the Rasch Model with the stacking technique in Winsteps. The results showed an overall increase in students’ scientific literacy after the learning intervention, as indicated by higher posttest measures compared to pretest measures for most students. STEM-based Deep Learning was implemented through contextual and project-based activities that engaged students in exploring renewable energy concepts, collaborating in groups, assembling simple renewable energy models, and presenting their work. These learning experiences encouraged students to connect scientific concepts with real-life situations and actively participate in the learning process. The findings suggest that STEM-based Deep Learning can support the development of scientific literacy in elementary science learning, particularly on renewable energy topics. Further studies involving larger samples and comparison groups are recommended to strengthen the evidence regarding its effectiveness.

Land Suitability Evaluation for Rubber Cultivation on Hilly Land in Nagari Sitanang, Lareh Sago HalabanDistrict, Lima Puluh Kota Regency, West Sumatra
type: item
description: This study was conducted to identify the soil characteristics of hilly land, determine the actual and potential land suitability classes for rubber (Hevea brasiliensis), and identify the dominant limiting factors and their respective amelioration measures. The research employed a descriptive survey method involving field observation, soil sampling, laboratory analysis, and a land characteristic matching procedure against the growth requirements of rubber. Four land units were evaluated based on climate, water availability, drainage, root zone media, nutrient retention, erosion hazard, flood hazard, and land preparation. The findings revealed that rainfall, drainage, soil texture, soil depth, flood hazard, surface rock fragments, and rock outcrops were conducive to rubber growth. The principal limiting factors included an annual temperature of 22 °C, acidic to strongly acidic soil pH, low base saturation, low organic carbon content on steep slopes, a high coarse fragment content, and a high erosion hazard. The actual suitability classes obtained were S3-tc,nr for Unit A; S3-tc for Unit B; S3-tc,nr,eh for Unit C; and N-eh for Unit D. Following improvement interventions, Units A and B were upgraded to S2-tc, Unit C remained classified as S3-tc,eh, and Unit D remained classified as N-eh. Based on these results, rubber cultivation is recommended to be prioritized on Land Units A and B, implemented on a limited scale on Land Unit C with the application of intensive soil conservation practices. It is not recommended for Land Unit D due to its permanent topographical constraints.

Optimizing Lime Mordant Conditions for Cotton Dyeing with Dragon Fruit Peel Extract
type: item
description: This study investigates the extraction and application of natural colorants from dragon fruit (Hylocereus polyrhizus) peels for cotton fabric dyeing. A maceration process produced a concentrated anthocyanin-rich extract, with absorption peaks at 475 nm and 536 nm. Experiments were conducted using a completely randomized design with three replicates per treatment. The effects of lime (Citrus aurantifolia) mordant concentration, pH, and immersion time on dye uptake and retention were measured using UV-Vis spectrophotometry. Dye retention, calculated from absorbance differences before and after fabric immersion and post-wash, served as an indicator of color stability. Optimal retention was observed at 2% mordant concentration and pH 6.5, with absorbance-based dye retention values of 0.212 at 475 nm and 0.215 at 536 nm. Higher mordant concentrations and lower pH reduced dye stability and brightness, while immersion time significantly influenced retention, with peak values at 475 nm after 30 minutes and improved retention at 536 nm after 120 minutes. These results demonstrate the potential of dragon fruit peel extract as an eco-friendly textile dye and highlight the importance of optimizing mordant concentration, pH, and immersion time to achieve vibrant, durable colors.

The Potential of South Sumatra Local Wisdom as a Source of Science Learning in Schools to Education Sustainable Development
type: item
description: Local wisdom is a learning resource that has the potential to support contextual and ethnoscience-based science learning. This research aims to map the concepts of science found in typical foods based on the Musi River and the Lebak Lebung agricultural system in South Sumatra, as well as analyze the needs of prospective teacher students for their use as a source of science learning. The research uses a qualitative descriptive approach supported by quantitative data. Qualitative data was obtained through field observations, interviews, and document analysis, while quantitative data was obtained through needs analysis of 89 prospective teacher students. The results of the study show that both contexts of local wisdom contain the concept of science including heat transfer, changes in the properties of materials due to heating, fermentation, the role of microorganisms, nutritional content, hydrological cycles, characteristics of swampland, adaptation of living things, and environmental conservation. The results of the needs analysis show that most students have sufficient knowledge in both contexts, but still need learning resources that are able to connect local knowledge with science concepts. These findings are the basis for the development of contextual ethnoscience-based science teaching materials to support meaningful learning and continuing education.

Education Environment as a Preventive Measure Pollution Plastic waste
type: item
description: Plastic waste pollution is a growing environmental problem, with the consequences of very high plastic use and increasingly severe environmental damage. Public awareness of waste management is also declining. This condition has negative impacts on the environment, such as soil, river, and sea pollution, and threatens human health and ecosystem sustainability. This study aims to analyze the role of environmental education in preventing plastic waste pollution and increasing public awareness of the importance of protecting the environment. This study uses a qualitative approach with a literature review method by collecting data from various scientific journals, books, and research reports. The results of recent studies published in 2020–2024 indicate that environmental education has a significant influence in shaping public knowledge, attitudes, and behavior towards plastic waste management. Education conducted through schools, families, communities, and digital media has been proven to increase public awareness to reduce plastic use, sort waste, and maintain a clean environment. Furthermore, practice-based educational programs are considered more effective in shaping environmentally conscious behavior than purely theoretical approaches. However, the implementation of environmental education still faces various obstacles, such as low community participation, a lack of waste management facilities, and a lack of continuing education programs. Therefore, collaboration between the government, educational institutions, families, and communities is needed to strengthen the educational environment to reduce plastic waste pollution effectively and sustainably.

type: item
description: This study aimed to evaluate dry matter intake (DMI), crude protein intake (CPI), and metabolite status, including blood urea nitrogen (BUN), glucose, and total protein, in female fat-tail sheep fed a complete feed. The study was conducted from July to September 2022 at a farmer group managed by PT Juara Agroniaga in Kanor Village, Bojonegoro Regency, East Java, Indonesia. A total of 200 female fat-tail sheep aged 1–2.5 years with an average body weight of 27 ± 4.65 kg were reared in 10 group pens (20 animals per pen). Feed intake was recorded daily for six weeks, and blood samples were collected to determine BUN, glucose, and total protein. Data were analyzed descriptively. The results showed that DMI and CPI were 71.00 ± 5.88 and 6.83 ± 0.57 g/kg BW0.75, respectively. Metabolite status showed BUN of 25.15 ± 6.94 mg/dL, glucose of 83.83 ± 14.43 mg/dL, and total protein of 4.54 ± 2.58 g/dL. The complete feed was consumed at an acceptable level under farmer conditions, as reflected by the observed DMI. however, the high fiber content and relatively low crude protein level may have contributed to suboptimal metabolite profiles. In conclusion, the nutritional quality of the complete feed influenced nutrient intake and was reflected in the metabolite status of female fat-tail sheep

The Effect of Microalgae Extract as a Biostimulant on Arabica Coffee (Coffea arabica L.) Callus Induction
type: item
description: Arabica coffee (Coffea arabica L.) is an economically important plantation crop in Indonesia, but its productivity is still relatively low. The purpose of this study was to influence Chlorella vulgaris extract as a biostimulant on in vitro callus induction using Arabica coffee leaf disc explants. The study method used a completely randomized design with six Murashige and Skoog (MS) media formulations consisting of synthetic plant growth regulator (PGR) (2,4-D and kinetin), 15% and 20% Chlorella vulgaris extract, and a combination of microalgae extract with PGR. The parameters observed included the percentage of explants with callus, color and texture, and explant contamination. The results and discussion of the media formulation significantly affected callus induction, while contamination was not significantly affected. PGR media and 15% Chlorella vulgaris extract treatment produced comparable callus formation percentages, indicating that microalgae extracts were as effective as synthetic PGRs in supporting early callus induction. Most of the calli were yellow to greenish in color with a compact texture, indicating the suitability of the callus induction stage, although further optimization is needed to obtain easily disintegrated calli for subsequent somatic embryogenesis. The conclusion shows the potential of Chlorella vulgaris extract as an environmentally friendly biostimulant for Arabica coffee tissue culture.

Ethnobiological Study of Postpartum Ritual Plants and Animals of the Malay Tribe in Semalah Village, Kapuas Hulu Regency
type: item
description: The Semalah Malay community in Kapuas Hulu Regency has a rich cultural heritage, including postpartum rituals that involve traditional healing practices using plants and animals. This knowledge is mainly preserved by village shamans, many of whom are elderly and have no successors, making it vulnerable to loss due to limited intergenerational transmission. In addition, scientific documentation of postpartum ritual biodiversity among this community remains limited. Ethnobiological studies are therefore important for recording local knowledge from the emic perspective and interpreting it through etic analysis. This study aimed to document the plant and animal species used in postpartum rituals by the Semalah Malay community in Semalah Village and to determine their relative cultural importance. A descriptive qualitative approach was employed, with data collected through in-depth interviews, participatory observation, and documentation. Descriptive statistics were used to calculate the Species Use Value (SUV). The results showed that the Semalah Malay community used 31 plant species and 4 animal species in 8 types of postpartum rituals. Turmeric (Curcuma longa) had the highest SUV among plant species, with a value of 1.78, indicating its central role in several ritual practices. Meanwhile, toman fish (Channa micropeltes) had the highest SUV among animal species, with a value of 1.00, reflecting its importance in postpartum recovery practices. These findings provide baseline ethnobiological data for preserving indigenous postpartum knowledge and supporting biocultural conservation in the Semalah Malay community.

Acid-Catalyzed Synthesis of Biodiesel from Calabash (Crescentia cujete) Seed Oil
type: item
description: This study evaluated the acid-catalyzed production of biodiesel from Calabash (Crescentia cujete) seed oil using sulfuric and nitric acids as transesterification catalysts. Oil extracted by Soxhlet extraction yielded 35.20% and was converted into biodiesel under various reaction conditions to determine the optimum catalyst loading, reaction time, temperature, and oil-to-methanol molar ratio. Sulfuric acid exhibited superior catalytic performance, achieving the highest biodiesel yield of 91.20% at 4% catalyst loading, 65 °C, 4 h, and an oil-to-methanol molar ratio of 1:12. Under optimum conditions, nitric acid produced a lower yield of 65.85% at 3% catalyst loading, 65 °C, 6 h, and a molar ratio of 1:9. GC-MS analysis identified seven methyl esters in the sulfuric acid-derived biodiesel, predominantly methyl hexadecanoate (16.93%), methyl stearate (15.07%), and methyl 9-octadecenoate (43.64%). Biodiesel synthesized using nitric acid contained eight methyl esters, with methyl hexadecanoate (16.55%), methyl stearate (26.90%), and methyl 9-hexadecenoate (21.51%) as the major components. The corresponding burning rates were 1.96 × 10⁻³ and 2.71 × 10⁻³ cm²/s for sulfuric and nitric acid catalysts, respectively. Overall, sulfuric acid proved more effective, producing higher biodiesel yield in a shorter reaction time and demonstrating the potential of C. cujete seed oil as a non-edible biodiesel feedstock.

Molecular Docking and ADMET Prediction of Bioactive Compounds from Centella asiatica, Coenzyme Q10, and Ethyl Ascorbic Acid Targeting PPAR Receptors as Potential Antioxidant Agents
type: item
description: Excessive ultraviolet exposure induces oxidative stress that accelerates skin aging, yet effective natural modulators of antioxidant pathways remain limited. This study investigated the potential of bioactive compounds from Centella asiatica, Coenzyme Q10, and ethyl ascorbic acid as PPAR receptor agonists associated with antioxidant regulation. An in silico approach was applied using molecular docking with Molegro Virtual Docker and ADME prediction analysis. Docking performance was evaluated using rerank scores and interaction analysis with key amino acid residues. Coenzyme Q10 and ethyl ascorbic acid isomers showed the most negative rerank scores (−62.08 and −55.65 kcal/mol), indicating strong receptor affinity. Asiaticoside and madecassoside formed extensive hydrogen and steric interactions with Arg284 and His280. ADME analysis revealed that ethyl ascorbic acid exhibited optimal balance between solubility, permeability, and safety. These findings suggest that ethyl ascorbic acid and Coenzyme Q10 are promising candidates for antioxidant therapy through PPAR activation. This study provides computational evidence supporting the development of natural antioxidant agents targeting oxidative stress–related skin damage.

description: This study examined the effect of an AI-integrated Deep Learning Project-Based Learning model on the critical thinking skills and scientific literacy of Primary School Teacher Education students at a university in Indonesia. A quasi-experimental non-equivalent control group design was employed involving 156 students, with 78 students in the experimental group and 78 students in the control group. Data were collected through critical thinking tests, scientific literacy tests, and a learning engagement questionnaire, then analysed using independent samples t-tests, N-Gain, Cohen’s d, and SEM-PLS. The experimental group achieved higher mean scores in critical thinking skills than the control group (84.28 vs. 71.33) and higher scientific literacy scores (83.10 vs. 71.50). The N-Gain values for critical thinking were 0.71 in the experimental group and 0.46 in the control group, while scientific literacy N-Gain values were 0.69 and 0.47, respectively. Cohen’s d values indicated very large effects for critical thinking skills (4.23) and scientific literacy (4.04). SEM-PLS showed positive relationships between the learning model and engagement (β = 0.72), engagement and critical thinking (β = 0.55), engagement and scientific literacy (β = 0.52), as well as direct effects on critical thinking (β = 0.68) and scientific literacy (β = 0.65). These findings indicate that the model supports meaningful, technology-enhanced learning.

Application of The Case-Based Method to Critical Thinking Based on Learning Motivation in Students of The Population Geography Course
type: item
description: This study investigated the effectiveness of a case-based learning (CBL) approach in improving students’ critical thinking skills in the Population Geography course at Universitas Negeri Padang. A quasi-experimental design was employed involving two classes: an experimental class receiving CBL and a control class receiving conventional instruction. Students with low, medium, and high initial abilities participated in the study. Data were collected through classroom observations and pretest–posttest assessments of critical thinking and analyzed using an independent-samples t-test and N-gain analysis with SPSS. The pretest results indicated no significant difference between the experimental and control groups, confirming comparable initial abilities. However, the posttest revealed a significant improvement in the experimental group compared with the control group. The experimental class achieved a higher mean posttest score (14.56) than the control class (9.85), with N-gain values of 84% and 31%, respectively, indicating substantially greater learning effectiveness. Further analysis showed that learning motivation did not significantly interact with the implementation of CBL in influencing critical thinking. The findings demonstrate that case-based learning effectively enhances critical thinking skills in Population Geography, regardless of students’ motivation levels, and supports its integration into geography education to promote higher-order thinking

Supporting SDG 11 Through Green Stormwater Infrastructure: SWMM-Based Flood Mitigation in a Tropical Watershed
type: item
description: The study sub-watershed covers 3475 ha with a main river length of 9.03 km. Rapid land-use change—residential areas grew by 623.84 ha while rice paddies declined by 1390.40 ha between 2013 and 2023—has reduced infiltration areas, increased impervious cover, and intensified peak runoff. Existing drainage infrastructure is insufficient to convey the 2-year design discharge, resulting in recurrent downstream flooding. This study analyzes existing hydrological and hydraulic conditions and designs rainwater management solutions through Green Stormwater Infrastructure (GSI) for flood mitigation and groundwater conservation. Design rainfall was estimated using Log Pearson III frequency analysis, while runoff and hydraulic responses were simulated using EPA SWMM 5.2. Three GSI alternatives were evaluated: 3946 infiltration wells reduced peak flood discharge by 15.64%; 37 retention ponds reduced peak flood discharge by 47.48%; and a combined system of 3181 infiltration wells and 33 retention ponds achieved the highest reduction of 64.11%. Channel normalization of the critical river segment (2U–3U) is essential regardless of the GSI alternative selected. The combined alternative is recommended as it simultaneously addresses flood peaks and groundwater recharge

Critical Thinking in Fluid Dynamics Learning: A Systematic Review of Learning Models
type: item
description: This study aims to identify learning models implemented to promote student’s critical thinking skills in fluid dynamics learning and synthesize evidence regarding their reported effectiveness. Using the PRISMA framework, seven empirical studies published between 2021 and 2025 and focusing on senior high school students were selected according to predefined inclusion criteria. The review examined student’s initial critical thinking conditions, instructional approaches, and reported learning outcomes. The findings indicate that student’s initial critical thinking skills in fluid dynamics were generally low to moderate, suggesting persistent difficulties in higher-order thinking processes. The reviewed studies implemented five instructional approaches, namely Problem-Based Learning, Guided Inquiry, RADEC, Metacognition Based Discovery Learning, and Think Pair Share, all of which were reported to support student’s critical thinking development. Several studies employing pretest–posttest measures reported moderate to high learning gains, while posttest-based studies showed higher critical thinking performance among students receiving innovative instruction. The reviewed evidence also suggests that students often experience difficulties in relating relationships among pressure, velocity, and flow rate to mathematical representations and scientific reasoning. Overall, student-centered instructional approaches contribute positively to critical thinking development in fluid dynamics learning, although their effectiveness varies across learning contexts and assessment indicators.

Assessment Instruments for Computational Thinking and Coding Skills to Support Quality Education: A Systematic Literature Review
type: item
description: This study aims to analyze the need for developing assessment instruments to measure coding skills and Computational Thinking (CT) among physics education students through a Systematic Literature Review (SLR). The literature search was conducted through Scopus and Google Scholar databases using systematic filtering procedures following PRISMA guidelines. The inclusion criteria covered studies addressing coding and/or CT in educational contexts, focusing on assessment instruments, providing full-text access, employing clear research methods, and published between 2022 and May 2026. The selection process identified 13422 initial articles, of which only 14 met all inclusion criteria. The findings reveal that studies specifically focusing on assessment instruments for coding and CT are still limited compared with research emphasizing instructional implementation. Most studies focus on Computational Thinking (9 studies), while only 2 studies discuss coding skills, and 3 studies indirectly examine both aspects. Based on educational levels, the studies are distributed across early childhood education (3), primary education (3), secondary education (1), higher education (2), and non-specific contexts (5). These findings indicate that research at the higher education level, particularly related to physics education, remains limited. Furthermore, no standardized instrument has yet been consistently applied to assess these competencies. However, recent developments in project-based assessment, STEM integration, and digital technology utilization demonstrate promising opportunities for more authentic assessment approaches. Therefore, this study highlights the importance of developing structured, valid, and reliable assessment instruments that not only evaluate learning outcomes but also capture students’ thinking processes during learning activities.

The Communication Strategy in Environmental Policy for Sustainable Development: A Review and Bibliometric Analysis
type: item
description: Environmental issues and the increasing urgency to achive sustainable development goals have highlighted the importance of effective communication strategies in environmental policy implementation. However, public resistance, low stakeholder participation, and ineffective policy dissemination remain major challenges in many countries. This study aims to conduct a systematic literature review related to the implementation of communication strategy in the field of environmental studies. This study uses a hybrid systematic literature review (SLR) and bibliometric analysis to investigate the role and communication strategy in environmental policy. VOSviewer and the PRISMA framework were used to evaluate 22 articles from the Scopus database (2017–2026). The results show that research in this field is still limited, indicating opportunities for further investigation. Communication strategies have been shown to significantly increase public acceptance of environmental policies, strengthen stakeholder participation, and encourage sustainable behavior change thru digital platforms, value-based framing, and participatory approaches. The main driving factors of effective communication include collaborative practices, adequate funding, and fair policy framing, while barriers include weak institutional structures, lack of community-based approaches, and negative public perception. The identified research gaps include the scarcity of longitudinal studies, limited research in developing countries, and inadequate interdisciplinary integration between environmental psychology and policy communication. These findings provide an evidence-based foundation for policymakers and researchers to enhance the effectiveness of environmental policy communication.

STEM-Based Deep Learning in Food Security Education for Sustainable Development Goals: A Systematic Review of Scientific Literacy and Self-Efficacy
type: item
description: This study aims to synthesize research on STEM-based deep or meaningful learning in food security and sustainability education, with a particular focus on its relationship with scientific literacy and self-efficacy. A systematic literature review was conducted using the PRISMA 2020 framework across Scopus, ERIC, Google Scholar, and SINTA-indexed sources. The screening process resulted in nine core studies that met the predefined inclusion criteria. The findings reveal that existing research is structurally fragmented across three domains: contextual STEM learning, pedagogical processes, and cognitive–affective outcomes. While STEM-based learning is widely applied in sustainability contexts, food security is predominantly treated as a thematic background rather than an epistemic learning domain. Furthermore, scientific literacy and self-efficacy are typically examined as separate constructs, limiting the understanding of how cognitive and affective dimensions interact in learning processes. In response to these gaps, this study proposes an integrative framework that connects food security as an epistemic context, STEM as an interdisciplinary structure, deep learning as a cognitive mechanism, and scientific literacy and self-efficacy as interconnected outcomes. In conclusion, this study highlights the need for integrative, context-driven STEM learning models to support meaningful and transferable learning in sustainability education.

The Effect of Emotional Intelligence, Adversity Intelligence, and Self-Confidence on Science Learning Outcomes of Junior High School Students in Tamalate District, Makassar City
type: item
description: This study aims to analyze the effect of emotional intelligence, adversity intelligence, and self-confidence on science learning outcomes of students at public junior high schools in Tamalate District, Makassar City. The research used an ex post facto design with a survey approach involving 294 eighth-grade students selected through purposive sampling. Data were collected using validated questionnaires and documentation of students’ science scores, then analyzed using descriptive statistics and multiple linear regression. The results show that emotional intelligence, adversity intelligence, and self-confidence are generally at a moderate level, although variations among students are evident. Science learning outcomes are also categorized as moderate, indicating that most students have met minimum competency standards but have not yet achieved optimal performance. Inferential analysis reveals that emotional intelligence, adversity intelligence, and self-confidence each have a positive and significant effect on science learning outcomes. However, simultaneously, these three variables show a more substantial collective influence, although their contribution remains relatively limited, suggesting the presence of other influencing factors outside the study. In conclusion, students’ psychological factors play an important role in determining science learning achievement. Therefore, learning strategies that integrate emotional regulation, resilience building, and self-confidence enhancement are needed to improve students’ academic performance in science.

The Effect of Differentiation Implementation in the Discovery Learning Model on Communication Skills and Learning Outcomes
type: item
description: This study aims to examine the effect of implementing differentiated instruction within the Discovery Learning model on students’ communication skills and learning outcomes. This research employed a quasi-experimental design with a posttest-only control group, involving 55 eleventh-grade students at SMAN 2 Bantaeng in the 2025/2026 academic year. The experimental class received differentiated Discovery Learning, while the control class was taught using conventional Discovery Learning. Data were collected through observation (communication skills) and essay tests (learning outcomes), and analyzed using descriptive and inferential statistics, including MANOVA. The results showed that students in the experimental class achieved higher communication skills than those in the control class. The mean score of oral communication in the experimental class (89.87) was higher than in the control class (77.08), while written communication scores were 87.99 and 75.38, respectively. In addition, 51.72% of students in the experimental class were categorized as very skilled, whereas no students in the control class reached this category. Learning outcomes also showed significant differences, with the experimental class achieving a higher average score (85.14) compared to the control class (75.85). Most students in the experimental class were in the high (75.86%) and very high (13.79%) categories, while the control class was dominated by the moderate category (84.62%). These findings indicate that the integration of differentiated instruction within the Discovery Learning model is effective in improving students’ communication skills and learning outcomes. This approach supports more equitable learning, accommodates diverse student needs, and promotes the development of essential 21st-century skills such as critical thinking, collaboration, and communication.

Family-Based Health Education as an Effort to Improve Self-Care Management among Elderly with Type 2 Diabetes Mellitus Toward Sustainable Development Goal 3
type: item
description: Type 2 Diabetes Mellitus (T2DM) among elderly individuals remains a major global health challenge and contributes to Sustainable Development Goal 3 (Good Health and Well-Being). Elderly patients often experience limitations in self-care management due to cognitive decline, multimorbidity, and reduced physical function. This study aimed to analyze the effectiveness of family-based health education interventions in improving self-care management among elderly patients with T2DM. A systematic literature review was conducted following the PRISMA guideline. Articles were obtained from PubMed, CINAHL, ScienceDirect, and Garuda databases published between 2019–2024. The review included quantitative studies using randomized controlled trials and quasi-experimental designs. Study quality was assessed using the Joanna Briggs Institute (JBI) Critical Appraisal Tool. A total of 13 studies met the inclusion criteria. The findings showed that family-based health education significantly improved dietary adherence, medication compliance, self-monitoring of blood glucose, self-efficacy, and glycemic control, including reductions in HbA1c levels (p < 0.05). Family involvement also enhanced emotional support and continuity of care at home. In conclusion, family-based health education is effective in improving self-care management among elderly patients with T2DM.
