Science, Character, Elementary School: A Hybrid Systematic Literature Review and Bibliometric Analysis
type: item
description: The integration of science learning and character education in elementary schools has increasingly attracted scholarly attention; however, the field lacks a comprehensive synthesis mapping its intellectual development, dominant themes, and methodological trajectories. This study aims to systematically examine publication trends, thematic structures, research designs, and emerging gaps in science–character integration at the elementary education level. A hybrid Systematic Literature Review (SLR) combined with bibliometric analysis was conducted on 51 Scopus-indexed articles published between 1997 and 2025. Article selection followed the PRISMA protocol, while co-occurrence and co-authorship analyses were performed using VOSviewer to identify conceptual and collaboration patterns. The findings demonstrate a marked growth in publications after 2018, with Southeast Asia as the primary contributor. Three major thematic clusters emerged: inquiry-based and literacy-oriented science learning, character value development emphasizing responsibility and religiosity, and integrative contextual pedagogical approaches. Quantitative experimental designs dominated the literature, primarily examining impacts on students’ motivation, conceptual understanding, and character formation, whereas longitudinal and mixed-method studies remain scarce. The review highlights the need for interdisciplinary and culturally responsive pedagogical frameworks capable of integrating scientific competencies and character development. This study provides an evidence-based reference for researchers and educators seeking to advance holistic science education in elementary schools.

Improving Generic Science Skills through an Interactive Web-Based STEM-PjBL Hybrid Model in Materials Physics with a Deep Learning Approach (A Review)
type: item
description: The development of generic science skills is a crucial objective in contemporary science education to address the demands of 21st-century competencies. This study aims to explore the potential of a Hybrid STEM–Project-Based Learning (PjBL) model supported by web-based interactive learning environments and deep learning approaches in enhancing generic science skills within physics learning materials. A Hybrid Review methodology was employed, integrating a Systematic Literature Review (SLR) and a Bibliometric Review. A total of 30 peer-reviewed articles indexed in Scopus and SINTA, published between 2020 and 2026, were systematically analyzed. Bibliometric mapping was used to identify research trends, thematic clusters, and emerging research gaps, while the SLR examined instructional designs, learning outcomes, and pedagogical effectiveness. The results indicate that STEM–PjBL consistently improves students’ generic science skills, including scientific reasoning, problem-solving, data interpretation, and conceptual modeling, particularly when supported by interactive web-based platforms. These platforms facilitate visualization, collaboration, and iterative inquiry processes that are essential in learning abstract physics concepts. Furthermore, the findings highlight that deep learning approaches offer strong potential to provide adaptive scaffolding, personalized feedback, and learning analytics to support students’ inquiry processes, although their implementation in STEM–PjBL contexts remains limited. This study concludes that the integration of STEM–PjBL, web-based interactivity, and deep learning constitutes a promising and scalable framework for advancing generic science skills and provides important implications for future research and instructional design in science education.

Differentiated Learning Strategies on Students' Science Learning Outcomes: A Systematic Literature Review
type: item
description: In the independent curriculum, differentiated learning is known. Differentiated learning views students differently and dynamically. In this case, teachers view learning from various perspectives. However, this does not mean that differentiated learning is individualized learning. Differentiated learning is a learning approach that adapts learning to the needs of students starting from interests, learning styles, student readiness and other characteristics. In the process, differentiated learning consists of two types, namely differentiation based on learning styles and differentiation based on learning abilities. This study aims to explore differentiated learning related to the research design used, the right learning model, the effect of differentiated learning on students' science learning outcomes and the profile of the use of differentiated learning in science learning at various levels of education. This study is a systematic literature review using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses method. Publish or perish was used to collect data from Google Scholar with a span of 2021-2025, 1000 articles were identified and filtered based on criteria, resulting in 15 articles that met the criteria. Research on differentiated learning mostly uses Classroom Action Research (CAR) design. The learning model that is widely used is by combining differentiated learning strategies. Differentiated learning has a positive impact on student learning outcomes and activities. Differentiated learning can be applied at every level of education.

type: item
description: The objective of this study is to investigate how STEM (Science, Technology, Engineering, and Mathematics) education contributes to enhancing self-efficacy and control-of-variables strategy (CVS) skills among prospective elementary school teachers, using a Systematic Literature Review (SLR) methodology. This research examined 15 well-regarded international articles that were published between 2020 and 2025 and are indexed by Scopus. To guarantee a systematic, transparent, and responsible review process, the identification, selection, and inclusion of literature were carried out in accordance with PRISMA guidelines. The findings concerning STEM learning models, instructional strategies, and their effects on the psychological and cognitive aspects of prospective teachers were synthesized using thematic analysis. Studies show that STEM approaches based on inquiry, project-based learning, and engineering design consistently improve prospective teachers' self-efficacy in science teaching and strengthen their ability to regularly control variables in experiments. Furthermore, the implementation of the Flipped Classroom model and the integration of digital technology contributes to meaningful learning experiences (mastery experiences), enhanced collaboration, and the development of analytical thinking and problem-solving skills. However, several challenges remain, such as the gap between theory and practice, differences in program duration, and limitations in the development of computational literacy. Overall, STEM learning contributes to preparing prospective elementary school teachers who are confident, reflective, and competent in designing inquiry and technology based science lessons to support the creation of quality science education.

A Review: Research Trends on Local Wisdom-Based Empathy Values in Science Learning
type: item
description: The integration of empathy values into science education has gained increasing scholarly attention as part of character education and holistic learning paradigms. In multicultural contexts such as Indonesia, local wisdom offers culturally grounded moral frameworks that can strengthen students' socio-emotional competencies, particularly empathy, within science learning. This study aims to synthesize and map global and national research trends on empathy-based local wisdom in science education through a hybrid review approach, combining a Systematic Literature Review (SLR) and bibliometric analysis. A systematic search was conducted across Scopus-indexed journals and SINTA-accredited Indonesian journals published between 2019 and 2025. Following PRISMA guidelines, 21 articles met the inclusion criteria and were analyzed qualitatively to identify conceptual frameworks, instructional models, learning outcomes, and assessment strategies related to empathy development in science education. The results indicate that embedding local wisdom—such as indigenous environmental ethics, communal values, and cultural narratives—into inquiry-based and project-based science learning significantly enhances students' empathy, environmental awareness, and ethical reasoning. However, empirical studies measuring empathy using validated psychometric instruments remain limited, particularly in experimental and longitudinal designs. Furthermore, international publications predominantly emphasize socio-scientific issues, while Indonesian studies focus more on contextual cultural integration. The findings suggest that future research should strengthen interdisciplinary designs, develop standardized empathy assessment tools, and expand cross-cultural comparative studies to advance globally relevant yet locally rooted science education practices.

Comparison of Dose Distribution with Graphical Optimization and Inverse Planning Techniques in Cervical Cancer Brachytherapy
type: item
description: Cervical cancer is the leading cause of death among women in Indonesia, with 36,964 new cases reported in 2022. Brachytherapy is a key component in treating advanced-stage cervical cancer, where dose optimization is critical to maximize the target dose (HRCTV) and minimize exposure to organs at risk. Graphical Optimization (GrO) and Inverse Planning (IP) techniques are commonly used, but comparative studies using Co-60 sources remain limited. Previous studies have largely used Ir‑192, so this study explores the comparison of GrO versus IP using Co‑60, which has not been widely studied in Indonesia. Co‑60 was chosen because it provides a dose distribution comparable to Ir‑192, has a longer half‑life reducing the frequency of source replacements and maintenance costs and has been reported to shorten patient treatment time by approximately 10%. This study compared the dose distribution of both techniques in 30 brachytherapy patients treated with a Co-60 source at Prof. Dr. I.G.N.G. Ngoerah Hospital. Data were analyzed using the Sagiplan 2.2.1 Treatment Planning System (TPS) following the TG-43 protocol. Evaluations included D90 HRCTV, COIN, DHI, bladder D2cc, and rectum D2cc based on ICRU Report 89 recommendations. MANOVA results (SPSS 29.0; significance < 0.05) showed that GrO’s D90 HRCTV (7.239 Gy ± 0.134 Gy) was significantly higher (sig = 0.006) than IP (7.155 Gy ± 0.093 Gy). GrO’s DHI (0.352 ± 0.043) was also superior (sig = 0.030), while COIN, bladder D2cc, and rectum D2cc showed no significant differences. Overall dose distribution for GrO differed significantly from IP (p = 0.011), though all parameters met ICRU standards. Conclusion: GrO excels in target coverage and homogeneity, while IP is equivalent in OAR protection. Both techniques are dosimetrically feasible, but GrO is more adaptive for complex anatomies despite requiring longer planning time.

type: item
description: Surabaya City has a lot of problems with the environment because of excessive urbanization and industrial activities, which include soil, air and water pollution. Among the pollutants of particular concern is heavy metal pollution. One method that can be tried in environmental remediation is phytoremediation, which is the use of plants to restore the environment. The present study focuses on identifying plants in Surabaya that have the capacity to function as heavy metal phytoremediation agents. The present study employs a purposive sampling method in conjunction with a line transect method. The results indicate that 34 plant species possess the capacity to function as effective heavy metal phytoremediation agents. A comprehensive review of the extant literature revealed ten types of heavy metal pollutants with the potential to be accumulated by heavy metal phytoremediation plants in the city of Surabaya, namely Pb, Hg, Cu, As, Fe, Al, Cr, Cd, Zn, and Ni. The diversity index (H') of 2.628, categorized as moderate, and the evenness index of 0.745, categorized as high evenness, indicate that the optimization of phytoremediation plant use can still be maximized by implementing sustainable planting activities as an effective strategy in controlling environmental pollution in large cities such as Surabaya.

Digital-Based Supervision of 21st-Century Skills: An Integrated Evaluation–Supervision Model Using E-MESp 4Cs Mobile
type: item
description: This study examines the implementation of a digital supervision system based on 21st-century skills using the E-MESp 4Cs Mobile platform as an integrated evaluation–supervision model in primary and secondary schools. The research employed an applied research design within a Research, Development, and Diffusion (RD&D) framework, with a specific focus on the implementation evaluation stage. The study involved teachers, principals, and supervisors from Muhammadiyah schools across four regions, comprising an initial pilot phase in Semarang City and an expanded implementation phase in Semarang Regency, Kendal Regency, and Salatiga City. Supervision was conducted through the integration of three core components: lesson planning, instructional implementation, and student learning products, aligned with the competencies of critical thinking, creativity, collaboration, and communication. The findings indicate a recurring gap between documented instructional planning and classroom practices, while instructional implementation and student learning products based on implementation evaluation data generally demonstrated stronger performance across regions. These results suggest that effective instructional practices are not always adequately represented in formal planning documents. The study concludes that digital, data-based supervision can provide a more comprehensive and reflective representation of instructional quality compared to conventional administrative supervision. Within the scope of this implementation-focused study, the E-MESp 4Cs Mobile platform shows potential to support professional development and evidence-based supervisory practices in 21st-century education.

Development of a Distractor-Based Cognitive Diagnostic Test (DB-CDT) on Thermodynamics Material to Detect High School Students' Data Literacy Skills
type: item
description: This study addresses the lack of specialized diagnostic instruments capable of pinpointing specific cognitive failures in physics data literacy, particularly within Thermodynamics. To bridge this gap, a Distractor-Based Cognitive Diagnostic Test (DB-CDT) was developed and validated for eleventh-grade high school students in Yogyakarta. Utilizing a Research and Development (R&D) approach with the ADDIE framework, the instrument was built upon the DINA (Deterministic Input, Noisy-AND Gate) cognitive diagnostic model. Expert validation by three specialists yielded an excellent average V-Aiken value of 1.00. Empirical testing on a sample of 540 students across high, medium, and low-tier schools confirmed high psychometric quality: an average INFIT MNSQ of 1.00 (within the 0.77–1.30 range), item difficulty between -2 and +2, and high reliability (0.92). DB-CDT distinguishes itself by using a Q-Matrix to link specific distractors to cognitive errors, such as failures in sign conversion or process interpretation. Analysis of student profiles revealed that the experimental group—utilizing targeted diagnostic feedback—achieved superior mastery in analyzing (96.6%) and interpreting data (90%), whereas the control group, receiving conventional assessment, struggled significantly with inference and synthesis. Theoretically, this research advances the application of Cognitive Diagnostic Models in physics education. Practically, it provides educators with a sensitive tool to profile individual student weaknesses, allowing for more focused instructional interventions in complex scientific topics.

Integration of Everyday Life Science Context in RME-Based Social Arithmetic Learning
type: item
description: This study develops and validates a Hypothetical Learning Trajectory (HLT) integrating everyday life science contexts within Realistic Mathematics Education (RME) framework for teaching social arithmetic to seventh-grade students. Through design research methodology involving three students with varying mathematical abilities, the research examined how contextually rich learning activities scaffold students' progression from informal to formal mathematical reasoning. Results demonstrated significant improvements in conceptual understanding across all ability levels, with most substantial gains observed among lower-ability students (143.8% improvement). Qualitative analysis revealed students' transformation from procedural memorization to conceptual reasoning, with contextual barriers rather than cognitive limitations identified as primary impediments to mathematical understanding. The HLT successfully facilitated students' development of meaningful connections between mathematical procedures and real-world applications, particularly in profit-loss scenarios and taxation calculations. These findings indicate that RME-based contextual integration creates effective pathways to conceptual mastery, offering inclusive learning opportunities that address persistent gaps between classroom mathematics and practical application. The research contributes to both theoretical understanding of mathematics learning trajectories and practical instructional design for meaningful mathematics education.

Overall Equipment Effectiveness (OEE) Analysis as a Framework for Mapping the Root Causes of Production Inefficiencies in Cream Filling Processes
type: item
description: This study aims to utilize Overall Equipment Effectiveness (OEE) analysis as a diagnostic framework to identify and map the root causes of performance losses in critical cream filling machinery within a cosmetics manufacturing company in East Java, recognizing that fragmented or piecemeal approaches to evaluating machine performance often fail to capture the interrelated sources of production inefficiency. The research was conducted over a three-month period using a descriptive quantitative method through direct observation of filling machine operations. The collected data included machine operating time, downtime, production output, and defective units. In this study, OEE was applied not merely as a performance indicator but as a loss-based diagnostic tool capable of systematically revealing hidden inefficiencies affecting equipment effectiveness. The results show that OEE values fluctuated significantly between 20.31% and 90.51%, with monthly averages of 71.12%, 80.62%, and 61.29%, respectively. While the quality component remained relatively stable at above 98%, substantial variations were observed in availability and performance due to machine downtime and reduced operating speeds. Further analysis using the Six Big Losses framework identified setup and adjustment time and idling or minor stoppages as the dominant contributors to decreased machine effectiveness, confirming that the filling machine functions as a critical production bottleneck whose instability directly influences production continuity. These losses collectively accounted for the majority of production interruptions and performance deterioration throughout the observation period. The findings underscore the importance of systematically reducing the Six Big Losses to stabilize and improve OEE. Implementing preventive maintenance, minimizing setup time variability, and strengthening operational discipline are therefore essential steps for achieving sustainable improvements in machine effectiveness …

Refining Pedagogical Skills in LS-Driven TP: Insights into PSCST’s Professional Competence
type: item
description: This quantitative study examines the impact of a teaching practicum, integrated with Lesson Study, on the pedagogical competency of 93 pre-service science teachers in the Pendidikan Profesi Guru (PPG) program at Universitas Tadulako, Indonesia. This study is a quantitative survey using purposive-stratified sampling (N = 93 PPG teachers). The data relied on self-assessment questionnaires, risking subjective bias. The intervention included iterative Lesson Study cycles (Plan–Do–See–Reflection). Practically, the results support LS-based practicum improvement, but generalization is limited to similar PPG contexts and regional settings. Data were gathered using self-assessment questionnaires and bolstered by Lesson Study, using a validated 5-point Likert-scale instrument that was aligned with the four phases of Lesson Study (Plan, Do, See, Reflection). The findings supported H₁ and rejected H₀, indicating a high level of general pedagogical competency (M = 3.62, SD = 0.45). Plan (M = 3.67) and Do (M = 3.65) phases showed strengths, especially in ICT integration and conceptual clarity, while See (M = 3.55) and Reflection (M = 3.58) phases showed relative deficiencies. Regression analysis revealed that Reflection ratings significantly predicted overall competency (β = 0.32, p < 0.001, R² = 0.28), and repeated-measures ANOVA validated significant phase differences (F (3,276) = 4.82, p = 0.003, η² = 0.05). The results demonstrate how well Lesson Study promotes evidence-based pedagogical development, particularly through iterative reflection, and provide empirical evidence in favor of its broader implementation in Indonesian PPG programs to improve science teacher training in areas with limited resources. This study contributes theoretically by operationalizing PSCST-based pedagogical competence within a Lesson Study framework.

Sleep Quality Among Employees of Institut Teknologi Sumatera (ITERA), Lampung, Indonesia: A Cross-Sectional Study in Higher Education Using the Pittsburgh Sleep Quality Index (PSQI)
type: item
description: Sleep is a vital physiological process essential for overall health and productivity. Among university employees, poor sleep quality has been linked to reduced job performance, increased risk of mental health disorders, and heightened susceptibility to occupational burnout. These risks are particularly salient in academic environments, where high administrative demands and blurred work-life boundaries are increasingly common. This study evaluated sleep quality among employees at Institut Teknologi Sumatera (ITERA) while investigating key demographic predictors. Employing a cross-sectional quantitative design, data were collected from 300 administrative and academic staff using the Pittsburgh Sleep Quality Index (PSQI). Initially, a chi-square goodness-of-fit test was conducted to assess the associations among categorical variables, and a generalized linear model (GLM) was subsequently utilized to identify factors influencing sleep quality, with a significance threshold of p < 0.05. The results revealed that approximately 75.67% of employees exhibited good sleep quality. Notably, significant sex differences were observed: females demonstrated a higher prevalence of poor sleep quality compared to males. Furthermore, age emerged as a critical predictor, with employees in the 41–50 age group reporting better sleep quality than those in the 21–30 and 31–40 age groups. These findings underscore the importance of considering demographic factors when developing targeted interventions aimed at improving sleep health in organizational settings.

Development of a Science Flipbook within the Framework of NTT Local Wisdom to Enhance Junior High School Students’ Conceptual Understanding
type: item
description: The widespread availability of instructional materials, particularly textbook packages, allows students to access learning resources either independently or through schools. However, many of the images and phenomena presented in these materials originate from contexts unfamiliar to students, requiring them to imagine situations they have never encountered. To address this issue, instructional materials were developed based on real-world problems drawn from local contexts, specifically salt production and gula lempeng (traditional palm sugar) production from palm sap, to provide meaningful and contextual learning experiences. This study employed a research and development approach using the ADDIE model. Data collection involved questionnaire techniques for validating the instructional materials through expert validation sheets, as well as test techniques to measure students’ conceptual understanding after implementation. The validation results showed that the instructional materials achieved high feasibility scores in terms of material (0.90), language (0.85), presentation (0.83), and media (0.86), all of which fall within the very valid category. Furthermore, students’ conceptual understanding test results exceeded 80%, indicating very good mastery of the concepts. These findings suggest that science instructional materials based on local wisdom and supported by a flipbook format are highly valid and effective in optimizing students’ conceptual understanding of temperature, heat, and thermal expansion.

type: item
description: This study investigates the quantitative characteristics of several generations of self-pollinated lines and the F2 population, as well as the correlation between these characteristics and leaf angle, harvest age, and yield in corn plants. The experiment was carried out in Gumantar village, North Lombok, from May to September 2024, and was designed using a Complete Randomized Block Design with treatments including the F2 population, 15 S1 lines, 15 S2 lines, 15 S3 lines, and 15 S4 lines. The study examined 14 quantitative characteristics. The experimental data were analyzed using analysis of variance. Further testing was conducted using the DMRT test at a 5% level. Correlations between traits were calculated using the Pearson correlation test. The research results demonstrate that the quantitative characteristics of several generations of selfing lines and the F2 population differ, except for ASI and cob diameter. The selfing from the first through fourth generations exhibit lower values compared to the F2 population, with the exceptions of anthesis-tasseling age, silk emergence, and harvest age. Most traits are associated with the medium harvest age category. The yield is correlated with most quantitative characters in the medium to strong category. The selection of plants to be selfed to form the S5 lines and increase yields should use plant height as a selection criterion.

Environmental Anxiety among Students in Islamic Boarding Schools: A Comparative Study
type: item
description: Environmental anxiety has increasingly been recognized as a significant psychological response to the global ecological crisis, particularly among adolescents within formal educational settings where climate change discourse is integrated into learning processes. As schools function as primary spaces for cognitive, emotional, and moral development, understanding how educational contexts shape students’ ecological concerns become essential. This study examines the impact of educational background on students’ environmental anxiety by comparing Islamic boarding schools (pesantren) and non-Islamic schools in South Tapanuli Regency. Employing a quantitative comparative design, data were collected from 60 students (30 pesantren and 30 non-pesantren) using an adapted Environmental Anxiety Scale. The analysis covered five dimensions: fear of ecological disasters, future anxiety, ecological guilt, ecological paralysis, and denial. Findings indicate that non-pesantren students reported significantly higher anxiety levels across all dimensions (p < 0.05), while also demonstrating stronger pro-environmental behavior (p < 0.01). In contrast, pesantren students exhibited lower anxiety levels, potentially reflecting the internalization of religious values and communal support as adaptive coping mechanisms. These findings suggest that educational background significantly influences adolescents’ emotional and behavioral responses to environmental challenges. The study contributes to policy discourse by emphasizing the integration of ecological literacy with spiritual and ethical reflection to foster ecological resilience and responsible behavior among young learners.

Birds as Biodiversity Barometers in the Anthropocene: Updating Concepts, Correcting Biases, and Scaling Indicators for Policy Impact
type: item
description: Birds are powerful biodiversity indicators due to their wide distribution and responsiveness to environmental pressures. Building on prior reviews, we synthesize methodological advances to update the Multi-species Bird Index (MSI) field. This study recaps limitations like European/breeding-season biases and uncertainty gaps while integrating recent studies that expand analytical rigor. Advances in passive acoustic monitoring, remote sensing, and trait-based models now improve species selection and reduce detectability errors. We translate these into practical guidance for policy application and a research agenda emphasizing seasonal completeness. The synthesis underscores birds’ role as decision ready barometers and provides a blueprint for robust monitoring. Birds serve as premier biodiversity barometers due to their cosmopolitan distribution and sensitivity to anthropogenic pressures. However, traditional Multi species Bird Indicators (MSIs) often suffer from significant Europe-centric and breeding-season biases that limit their global policy impact. This study synthesizes recent methodological breakthroughs to update the MSI framework. We evaluate the integration of Passive Acoustic Monitoring (PAM), high-resolution remote sensing (ALS LiDAR), and trait-based selection criteria into standard monitoring protocols. Our synthesis reveals that combining automated sensor networks with hierarchical Bayesian models effectively mitigates detectability errors and fills critical data gaps in under-represented regions. Furthermore, linking avian indicators with carbon sequestration and equity metrics allows for more robust prioritization of Nature based Solutions (NbS). We provide a practical blueprint for next-generation indicators that emphasize seasonal completeness and statistical rigor. By shifting from retrospective reports to forward-looking policy tools, these refined barometers can more accurately track progress toward global biodiversity targets.

AAS-Based Multi-Media Diagnostic Approach for Evaluating Heavy Metal Contamination in the Batang Ayumi River Within the Batu Bola Landfill Influence Zone
type: item
description: This study applies an integrated multi-media approach (river water–sediment–shallow groundwater) to assess heavy metal contamination (Pb, Cu, Cd, Fe, and Hg) along the Batang Ayumi River within the influence zone of the active Batu Bola landfill, a setting rarely evaluated in an integrated manner. Samples were collected from four stations (upstream control to downstream) and analyzed using atomic absorption spectrophotometry (AAS). Fe and Pb emerged as the most responsive indicators of landfill influence: Fe increased downstream and was reflected by accumulation in sediments, while Pb showed greater mobility in river water and nearby wells, suggesting transfer from surface transport to shallow groundwater. Cu peaked upstream, whereas Cd and Hg were relatively stable but detectable across media. Although concentrations remained below applicable standards, the spatial patterns indicate persistent environmental pressure that could intensify without improved controls. By integrating evidence across water, sediment, and groundwater, this study clarifies plausible heavy-metal migration pathways from landfill leachate—surface-water transport, sediment retention, and infiltration toward shallow aquifers—supporting targeted leachate management and long-term multi-media monitoring.

Impact of Persuasive Instagram Posts on Gen Z Mangrove Ecosystem Concern
type: item
description: Mangroves are a type of tree that play an important role in maintaining the balance of the coastal ecosystem. The decline in mangrove area and function due to urbanization pressures requires the active involvement of the younger generation in conservation efforts, particularly through digital media. Mangrove conservation activities necessitate the involvement and knowledge of Generation Z. Communication is an aspect that can impact knowledge of mangrove conservation. However, communication delivered in the form of visual images, audio, or graphics that explain the negative impacts makes people feel compelled to participate or vice versa. The purpose of this study is to examine the effectiveness of persuasion of positive and negative information posted on the Jakarta Mangrove Community's Instagram social media account on Generation Z's understanding of the mangrove forest ecosystem in Jakarta. The method employed is a quantitative survey with data collection procedures utilizing a questionnaire. An examination of survey data for Generation Z reveals a good association between the type of Instagram social media material and environmental awareness of the mangrove ecosystem. Whereas the substance of Instagram posts providing positively or negatively packaged critical information on mangrove forests and their environmental impact has a large overall influence on Generation Z's understanding of the need for mangrove forest ecosystems. Using Instagram as a social media platform to raise awareness among Generation Z communities about the efforts that can be made to conserve mangrove forest ecosystems is an effective technique.

Antimicrobial Potential of Ethanol Extract from Avocado Seeds (persea americana mill.) on The Healing of Socket Wounds from Tooth Extraction in Male Wistar Rat
type: item
description: Healing of tooth socket wounds after tooth extraction is a complex process involving phases of inflammation, proliferation, and tissue remodeling. Avocado seeds (Persea Americana Mill.) are known to contain bioactive compounds, including flavonoids, saponins, tannins, and triterpenoids, which have the ability to accelerate the wound healing process. This study aims to determine the effectiveness of avocado seed ethanol extract gel on changes in body weight, socket wound diameter, and socket depth after tooth extraction. This study used a laboratory experimental design with a post-test only control group design using male Wistar rats as test animals. The samples were divided into five groups, consisting of a negative control, a positive control (Gengigel), and treatment groups with avocado seed ethanol extract gel at concentrations of 10%, 20%, and 30%. Body weight was measured from day 1 to day 14. The diameter and depth of the socket wound were also measured periodically. Data analysis used the Paired Samples T-Test, Welch ANOVA, and Dunnett T3 Posthoc test in accordance with the results of normality using the Shapiro-Wilk test and data homogeneity using the Levene test. Based on the results of the study, it was found that 10% ethanol extract gel from avocado seeds was most effective in maintaining the stability of the body weight parameters of the test animals, and 30% ethanol extract gel from avocado seeds was most effective in accelerating the reduction in wound diameter and depth, with results comparable to the gold standard (Gengigel). It can be concluded that ethanol extract gel from avocado seeds, especially at a concentration of 30%, is effective in accelerating the healing process of socket wounds after tooth extraction.

Improving Production Strategies through Monitoring Visual and Physicochemical Changes in Gambier Catechin-Based Shampoo Bars under Practical Storage Conditions
type: item
description: The development of eco-friendly cosmetics using local bioresources like Uncaria gambir Roxb. (gambir) holds strong promise for sustainable innovation. This study formulates and evaluates a catechin-based solid shampoo enriched with purified gambir extract, aiming to enhance product stability. A 14-day storage test was conducted at 20 °C and 40 °C using three types of packaging: translucent plastic, aluminum foil, and amber glass. Visual observations revealed that higher temperatures, especially in translucent plastic, accelerated color degradation due to catechin instability. Amber glass was the most effective in preserving the shampoo’s original color. Further, aqueous stability was assessed through two wet-use simulations: soaking (full immersion in distilled water) and dipping (partial immersion daily over four days). The shampoo maintained physical integrity during both tests, showing no softening or structural deformation. However, water discoloration increased over time, indicating catechin release and oxidation. The extent of browning was influenced by the pH of the water, suggesting that both environmental pH and oxidative exposure affect catechin behavior during use. These results demonstrate the solid shampoo’s physical resilience and moderate color stability under thermal and aqueous stress. While catechin oxidation is unavoidable, its rate can be mitigated through optimal packaging and pH management. The gambir-based solid shampoo shows potential as a natural, environmentally friendly personal care product, although further formulation refinement is needed to improve color retention during storage and use.

description: This study aimed to conduct phytochemical analysis and toxicity testing of Red Turmeric (Curcuma zedoaria) and White Turmeric (Curcuma mangga) extracts in male Wistar rats (Rattus norvegicus). This study employs an experimental design conducted at the Poltekkes Kemenkes Banjarmasin laboratory. Phytochemical screening was undertaken to detect bioactive compounds utilizing spectrophotometry for quantitative analysis, with each compound evaluated in triplicate. The experimental subjects were male Wistar rats, divided into two treatment groups (300 mg/kgBW and 2000 mg/kgBW), with observations recorded at multiple intervals (30 minutes to 14 days) post-administration. Toxicity indicators included physical symptoms such as skin conditions, lethargy, and survival status. Data were analyzed descriptively, calculating the mean and standard deviation for phytochemical content and employing frequency tables to highlight clinical symptom patterns. Results showed that both types of turmeric contain these compounds, with White Turmeric having higher phenolic (23.41 mg/g) and flavonoid (17.21 mg/g) contents than Red Turmeric (21.72 mg/g and 15.50 mg/g, respectively). These findings indicate a higher antioxidant potential in White Turmeric. In the toxicity test, two doses (300 mg/kgBW and 2000 mg/kgBW) were tested through observations of physical conditions, including skin and fur, as well as clinical symptoms such as lethargy, seizures, tremors, diarrhea, and survival status.

Reliable Assessment of Long-Term Land Use Change to Support Sustainable Watershed Management Using Multi-Sensor Landsat Imagery
type: item
description: Land use change analysis is widely applied in watershed studies, yet its reliability is often limited when multi-temporal classification accuracy is not systematically evaluated. This study aims to assess long-term land use change while emphasizing the accuracy and reliability of change detection in the Petung Watershed, East Java, Indonesia. Multi-temporal Landsat imagery from Landsat 7, 8, and 9 (2005–2024) was analyzed using a supervised classification approach implemented in ArcGIS. Classification accuracy was evaluated using a confusion matrix and the Kappa coefficient to ensure temporal consistency and methodological reliability. The results indicate a clear shift in land use patterns, characterized by a continuous decline in vegetation cover and a substantial expansion of agricultural and built-up areas. Classification reliability is supported by Kappa coefficient values ranging from 0.701 to 0.829, corresponding to substantial to almost perfect agreement, with the highest accuracy achieved in the later observation years. These findings demonstrate that the proposed supervised, GIS-based framework provides a reliable and replicable approach for accurately measuring long-term land use change at the watershed scale. While the methodology can be applied to other regions, the observed land use dynamics are specific to the Petung Watershed and reflect local environmental and anthropogenic conditions.

type: item
description: This study aims to develop an accurate monthly rainfall prediction model for Sabang City, Indonesia, to support agriculture, disaster mitigation, and water resource management in coastal regions with complex climatic conditions. An Artificial Neural Network (ANN) trained using the Levenberg–Marquardt (LM) algorithm was employed, combining the Gradient Descent and the Gauss–Newton methods to enhance convergence speed and training stability. Meteorological data from 2015–2024, including temperature, humidity, air pressure, sunshine duration, wind direction, wind speed, and rainfall, were obtained from the Maimun Saleh Meteorological Station. Model performance was assessed using Mean Squared Error (MSE), Root Mean Squared Error (RMSE), Mean Absolute Error (MAE), Mean Absolute Percentage Error (MAPE), and the coefficient of determination (R²). The optimal architecture consisted of a single hidden layer with 25 neurons, producing an MSE of 955.84 mm², an RMSE of 30.91 mm, an MAE of 23.06 mm, a MAPE of 34.8%, and an R² of 0.93. These results indicate that the ANN-LM model effectively captures nonlinear climatic relationships and seasonal rainfall variability. The MAPE value falls within the acceptable range reported in forecasting literature, demonstrating practical reliability. Overall, the ANN-LM approach outperformed conventional backpropagation in accuracy and training efficiency, indicating its suitability for rainfall prediction in coastal areas.

Identification and Diversity of Insects Associated with Tim-Tim Coffee (Coffea arabica x Coffea canephora) in Rusip Antara, Central Aceh, Indonesia
type: item
description: Coffee plantations support diverse insect communities that play key roles in pest regulation, pollination, and ecosystem stability. This study analyzed insect family composition, abundance, and community structure in the Tim-Tim (Typica) coffee plantation ecosystem in Rusip Antara Subdistrict, Central Aceh Regency, using different trapping methods. Sampling was conducted from May to September 2025 in one representative plantation block with three observation plots, each containing 25 coffee plants. Three types of traps were employed: light traps, yellow plate traps, and malaise traps. Insect community structure was analyzed using the Shannon–Wiener diversity index (H’), evenness index (E), and similarity index. A total of 2,659 individuals from 65 families were recorded, dominated by Hymenoptera, Diptera, Coleoptera, and Hemiptera. Light traps captured the highest number of individuals and exhibited the highest diversity (H’ = 2.34), reflecting the activity of nocturnal insects attracted to light. Yellow plate traps showed moderate diversity (H’ = 1.77) but the highest evenness (E = 0.80), indicating balanced diurnal insect communities. Malaise traps recorded lower diversity (H’ = 1.33) and evenness (E = 0.57), primarily capturing high-flying insects such as Diptera and Hymenoptera. Similarity analysis revealed moderate to low overlap among trap types, demonstrating that different traps capture complementary components of the community. These findings highlight the high insect diversity and ecological stability of the Tim-Tim coffee plantation and emphasize the importance of multiple trapping methods for understanding community structure and supporting natural biological control in sustainable coffee agroecosystems.

Cloning, expression and purification of a gene encoding CFP-10 and ESAT-6 protein of Mycobacterium tuberculosis in pET SUMO plasmids as Vaccine Candidates
type: item
description: The Bacillus Calmette-Guerin vaccine did not show consistent results in preventing tuberculosis, with an effectiveness ranging from 0% to 80%. More effective proteins are needed as vaccine candidates to eliminate tuberculosis. Culture filtrate proteins 10-kDa(CFP-10) and Excretory Antigen Target 6-kDa(ESAT-6) demonstrated very strong antigenicity against T and B cells. These proteins are secreted during the early phase of infection and could potentially be used for vaccine candidates. This study aims to clone and express the CFP-10 and ESAT-6 proteins on the pET SUMO Plasmid. PCR with specific primers was used to amplify the genes encoding CFP-10 and ESAT-6 proteins. The PCR products were cloned into pET SUMO plasmids for transformation into competent cells E.coli BL21(DE3). Recombinant protein expression was induced in LB medium using 1 mM IPTG. The yield of recombinant proteins was visualized by SDS-PAGE and western blotting using an Anti-HisTaq Antibody. PCR results showed the target gene sizes to be 304 bp (CFP-10) and 291 bp (ESAT-6). SDS-PAGE and Western blotting revealed proteins at 22kDa (CFP-10) and 18kDa (ESAT-6). The genes encoding the CFP-10 and ESAT-6 proteins of M. tuberculosis have been successfully cloned into the pET SUMO plasmid and expressed in E. coli BL21(DE3) with molecular weights corresponding to the target genes.

Impact of Essential Nutrient Deficiency on the Growth and Yield of Four Hydroponic Vegetable Crops Using a Split-Plot Design in Hydroponic Systems (Applied Plant Physiology Study)
type: item
description: Essential nutrients play critical roles in plant physiology; therefore, nutrient imbalance in hydroponics can rapidly reduce growth and yield. This study evaluated the effects of N, P, and K deficiencies on four hydroponic vegetable crops using a split-plot design to support nutrient-deficiency diagnosis and practical nutrient management. This study used a split-plot design, with four nutrient types as main plots: N0 (balanced N, P, K), N1 (nitrogen deficiency), N2 (phosphorus deficiency), and N3 (potassium deficiency). The second factor consisted of four types of vegetable crops as subplots: S1 (Pakcoy), S2 (Caisim mustard), S3 (Green Romaine), and S4 (Kangkung), resulting in 16 treatment combinations, each repeated four times, for a total of 64 experimental units. The results indicate that deficiencies in nitrogen (N), phosphorus (P), and potassium (K) significantly affect growth and yield in hydroponic systems. Across crops, N deficiency most consistently reduced vegetative growth and fresh weight, P deficiency primarily constrained root-related traits and leaf expansion, and K deficiency affected yield-related performance and quality attributes.

Innovation in Acid-Base Learning (PasamBa) through Ecoprint Batik as a Contextual Strategy to Improve Understanding of Fashion Design Students in SMK
type: item
description: This study aims to test the effectiveness of PAsamBa (Acid-Base Learning) learning innovation integrated with ecoprint batik practice in improving conceptual understanding and vocational skills of eleventh-grade students in the Fashion Design expertise program at Vocational High Schools (SMK). The acid-base concept has direct relevance to textile skill processes such as mordanting, color fixation, and pH stability of natural dyes, which are important in sustainable fabric dyeing. The study used a one-group pretest-posttest design involving 73 students from three vocational high schools in Aceh. The instruments included a 20-item acid-base concept understanding test (α = 0.86) and a vocational skills rubric that assessed procedural accuracy, color stability, and ecoprint pattern quality. The results showed a significant increase (t( 72) = 12.86; p < 0.001), with the average score increasing from 43.69 to 80.53 and an N-gain value of 0.67 (medium-high category, approaching high). Students' vocational skills also improved, with an average process score of 3.49 and a product score of 3.41 (scale 4). These results demonstrate that the PAsamBa–Ecoprint approach effectively integrates chemistry learning with contextual textile practices to strengthen students' conceptual understanding and readiness for the creative fashion industry.

Acute Toxicity Nanoemultion of Ethanol Extract of Clove Leaves (Syzygium aromaticum L.)
type: item
description: Clove leaves have been widely used as traditional medicine. Clove leaves are rich in saponins, flavonoids, tannins, sterols, and essential oils. To improve the function of clove leaves, one of them is by reducing the sample size into nanoemulsion form. Nanoemulsions were prepared using the sonication method and exhibited an average droplet size of 13.3 nm. The purpose of this study was to determine the toxic properties, the dose that can cause toxic effects, and the LD50 value of nanoemulsion administration of ethanol extract of clove leaves. This study used 25 male white rats which were divided into five groups, namely a control group (nanoemulsion base) and four treatment groups receiving oral doses of 5, 50, 300, and 2000 mg/kg BW. The LD50 value was calculated using AOT425 StatPgm in accordance with OECD TG 425 (Up and Down Procedure). Mortality summary: control 0/5; 5 mg/kg BW 0/5; 50 mg/kg BW 0/5; 300 mg/kg BW 0/5; 2000 mg/kg BW 5/5. The results showed an LD50 of 798.5 mg/kg BW and, based on the GHS, it falls under Acute Toxicity (Oral) Category 4 (300–2000 mg/kg BW). Clinical signs such as piloerection, grooming, and weakness appeared mainly in the early observation phase (from 30 minutes to 4/8/12 hours) in each dose group and were reversible.

Development of “Hydro Pure Pro (HPP)” Water Filter Technology to Reduce Iron (Fe) and TDS Levels in Drilled Well Water
type: item
description: High levels of iron (Fe) and total dissolved solids (TDS) in well water remain a major groundwater quality problem in Indonesia. This study aimed to develop and evaluate the effectiveness of a Hydro Pure Pro (HPP) water filtration system based on a multi-stage aeration–filtration process to reduce Fe and TDS concentrations. The HPP system combines activated carbon, zeolite, silica sand, mountain sand, and a reverse osmosis (RO) unit as final treatment, with a focus on assessing the effects of activated carbon raw materials (coconut shell and wood) and carbon bed thickness on adsorption performance. The results showed that coconut shell activated carbon exhibited superior performance, reducing Fe from 0.606 mg/L to 0.135 mg/L (77.72%) and TDS from 540 mg/L to 390 mg/L (27.8%) at a thickness of 20 cm. Increasing the carbon thickness to 30 cm improved removal efficiency to 79.9% for Fe and 28.7% for TDS, after which performance tended to stabilize. This improvement is attributed to the higher specific surface area and well-developed microporous structure of coconut shell activated carbon, which enhances Fe²⁺ adsorption through ion exchange and surface functional group interactions. In conclusion, the HPP system demonstrates high effectiveness and economic feasibility, making it a promising filtration technology for improving the quality of borehole water in community settings.

Ethnoscience Based Durian Acid Product Development for Sustainable Chemistry Education: A Project Based Study on Prospective Chemistry Teachers’ Creativity
type: item
description: This study aims to examine how an ethnoscience-based durian acid product-development project functions as a PCK-driven creative learning environment for prospective chemistry teachers and to analyze creativity across elaboration, originality, problem solving, and synthesis. A Classroom Action Research (CAR) design with an embedded mixed-methods approach was employed involving 68 fifth-semester pre-service chemistry teachers at the University of Riau. The intervention integrated Project-Based Learning (PjBL) stages—orientation, planning, implementation, and evaluation—within Plan–Act–Observe–Reflect cycles. Data were collected using creativity questionnaires, classroom observations, and interviews, and triangulated to validate findings. Results showed high agreement (74–93%) across creativity dimensions during orientation–implementation, supported by observed evidence of detailed planning, novel product ideas, and iterative troubleshooting. However, more neutral responses emerged during evaluation, indicating difficulties in evidence-based reflection and conceptual integration. The core chemistry concepts addressed included fermentation chemistry, pH interpretation, solution dilution, and acid strength comparisons. Triangulation was generally convergent, with partial divergence in originality during evaluation due to discrepancies between self-perceived novelty and observed pedagogical innovation. These findings suggest that ethnoscience-enriched PjBL effectively promotes creative PCK development, but requires structured scaffolding to strengthen data-driven justification and synthesis during reflective evaluation.

type: item
description: Pineapple is a key agricultural commodity in Subang Regency. One method of food diversification is transforming pineapple into pineapple jam. Mochi, a food product, can be filled with this pineapple jam. The chemical characteristics and consumer acceptance of pineapple mochi are influenced by the proper ingridients formulation. This study aims to determine the chemical and organoleptic characteristics of pineapple jam as mochi filling. The research design used in this study was a two-factorial Completely Randomized Design (CRD), with the factors being sugar concentration (30%, 40%, and 50%) and pectin concentration (without pectin, 0.015%, and 0.03%). The parameters tested included chemical analysis (water content, total acidity, total soluble solids, and Vitamin C content) and organoleptic evaluation (hedonic test for color, taste, texture, and aroma). The results showed that sugar and pectin treatment had a significant effect on water content G3 21.16b%, total acidity G1 1.90b%, and total soluble solids G3 77.26b%, but did not significantly affect Vitamin C content in the jam 2.20-7.33 m/100 g. Pectin treatment had a significant effect on water content P2 23,27a%, Vitamin C P3 7.09b%, total acidity P3 2.17c%, and total soluble solids P2 76.44b%. There was no interaction between the sugar and pectin treatments on the pineapple mochi jam. The hedonic test indicated that panelists generally liked the pineapple jam filling for mochi in terms of taste, aroma, color, and texture.

Empowering 21st-Century Learners: Enhancing Digital Literacy Through E-Literate Integration in Science Education
type: item
description: Digital literacy is a critical 21st-century competency that must be integrated into science education to achieve Sustainable Development Goal 4 (Quality Education). This study evaluates the effectiveness of the E-Literateapplication in enhancing students' digital literacy within the specific context of vibration and wave topics. Using a quasi-experimental pretest–posttest control group design, this research involved 60 grade VIII students divided into experimental and control groups. The research instrument utilized a performance-based digital literacy test (comprising case studies on information access, evaluation, processing, and digital ethics) to measure actual proficiency rather than mere self-perception. Data were analyzed using normalized gain (N-Gain), independent t-test, and Cohen’s effect size. The results indicated a significant difference in digital literacy improvement between the two groups (p < 0.05). The experimental group, which utilized the E-Literate app to simulate wave phenomena and verify digital information, achieved a very large effect size (d = 4.63). These findings demonstrate that the E-Literate application is not only an effective medium for mastering abstract science concepts like vibrations but also a powerful tool for bridging the digital skills gap in secondary education.

Understanding Sustainability Through Socio-Ecological Trade-Offs: Field Evidence of Traditional Oil Mining and Groundwater Quality Toward the SDGs
type: item
description: This study explores human-nature relationships through a socio-ecological perspective, focusing on traditional oil mining in Wonocolo, Indonesia, widely known as “Little Texas”. The analysis was conducted through field observations, in-depth interviews with 40 local stakeholders, and laboratory analysis of 40 groundwater samples collected from community dug wells. Results show residents rely on dug wells, piped-water, and artesian springs, with significant seasonal scarcity. Water quality assessment indicates that most physical parameters remain within acceptable limits (pH 6.40–8.00; electrical conductivity 0.43–2.26 mS/cm; temperature 22.00–31.00 °C). However, localized elevations in electrical conductivity at several sampling points suggest potential hydrochemical alterations in the shallow aquifer that may be associated with traditional oil extraction activities, particularly in a karst-dominated landscape. Although direct measurements of TPH and Oil & Grease were not available for a comprehensive ecotoxicological assessment, these findings highlight a critical socio-ecological trade-off in which short-term economic benefits from oil production may increasingly pressure long-term groundwater security. The study concludes that managing these interdependencies requires participatory governance and waste-stream regulation tailored to the karst landscape. Integrated policies are essential to ensure that economic benefits do not undermine the community's fundamental access to clean water, aligning with SDG 6 and SDG 12.

Water Content and Specific Gravity of Pulai (Alstonia scholaris) Coppice Wood: Potential Utilization
type: item
description: The study aims to determine the water content and specific gravity and analyze both on the potential utilization of pulai coppice wood. The study was conducted at the Forest Products Technology Laboratory, Forestry Department, Faculty of Agriculture, Palangkaraya University. Pulai coppice wood material was taken around the Palangka Raya University Campus, tree diameter 34cm, branch-free height 7m. Using a 2-factor factorial Randomized Block Design with 3 levels, the first factor is the axial direction, namely the base, middle and tip. The second factor is the radial direction, namely near the heart, between the heart and the bark and near the bark. The parameters observed were green water content, air-dry water content, green specific gravity, air-dry specific gravity and oven-dry specific gravity. The results showed an average value of green water content of 84.75%, air-dry water content of 18%, green specific gravity of 0.29%, air-dry specific gravity of 0.30% and oven-dry specific gravity of 0.31%. All parameter values ​​​​resulted from the research on pulai coppice wood were lower than the values ​​​​of the main stem pulai coppice wood from previous studies. In the axial direction, all parameter values ​​show an increasing pattern from base to tip, except for the wind-dry moisture content, which shows the opposite pattern. In the radial direction, the values ​​tend to be uniform, except for the green specific gravity, which decreases from the outside (near the bark) to the inside (near the heart). The results of the analysis of variance indicate that all parameters influence the axial direction, while only the green specific gravity influences the radial direction. This indicates that the axial factor dominates the physical properties of pulai coppice wood. The interaction factors that influence this are green water content and oven-dry specific gravity. Based on the specific gravity and wind-dry moisture content values, pulai coppice wood is lightweight and ada…

Objective and Existential Lecturer Authenticity as Drivers of Student Engagement and Learning Performance in Tourism and Hospitality Programmes
type: item
description: This study examines how lecturers’ authenticity—operationalised through objective authenticity (a lecturer’s adherence to transparent course standards and consistent professional conduct) and existential authenticity (the warmth, sincerity, and meaningfulness students perceive in the learning experience)—shapes student engagement and perceived learning performance in tourism and hospitality programmes. Drawing on Self-Determination Theory, a quantitative survey was administered to 196 undergraduate students across West Sumatra, Indonesia (August–October 2025), and the proposed model was tested via partial least squares structural equation modelling (PLS-SEM) using a two-stage higher-order construct approach. Results indicate that existential authenticity exerted a stronger positive effect on student engagement (β = 0.34, p < 0.001) than objective authenticity (β = 0.17, p = 0.048). St udent engagement predicted perceived learning performance (β = 0.39, p < 0.001). The model explained 26% of variance in engagement (R² = 0.26) and 15% in perceived learning performance (R² = 0.15). Student engagement fully mediated the relationship between objective authenticity and perceived learning performance, and partially mediated the relationship between existential authenticity and perceived learning performance. Findings underscore the value of meaning-centred, sincere teaching practices for building durable student engagement and enhancing perceived learning outcomes in practice-oriented hospitality programmes.

The Relationship Between Duolingo Usage Intensity as Reinforcement and Vocabulary Mastery and Learning Motivation of Junior High School Students
type: item
description: This study aims to evaluate the effectiveness of Duolingo as a reinforcement activity and analyze the relationship between objective and subjective usage intensity, vocabulary mastery, and learning motivation. Utilizing a quantitative approach with a correlational design, data was collected from 21 Junior High School students selected via purposive sampling. The instruments included digital logs from Duolingo for Schools, pretest-posttest vocabulary assessments, and questionnaires, which were analyzed using the Wilcoxon Signed Rank Test and Spearman Rank Correlation. The results demonstrated a significant increase in vocabulary mastery, achieving a medium N-Gain of 0.29, alongside high, predominantly intrinsic learning motivation with a mean score of 3.48. However, the discussion reveals a distinct "intention-behavior gap," showing a discrepancy between students' perceived subjective intensity and their actual objective usage logs. Furthermore, statistical analysis indicated no significant linear correlation between the duration of use and the improvements in vocabulary or motivation. In conclusion, while Duolingo serves as an effective structured reinforcement tool to enhance engagement and foundational vocabulary, the duration of app usage alone does not determine success, thereby highlighting an "illusion of productivity" within self-directed mobile learning.

Comparative Analysis of Integrated Crop Management (ICM) Implementation on Hybrid Maize Production and Farmers’ Income (Zea mays L.)
type: item
description: Hybrid maize (Zea mays L.) is one of the strategic commodities in Indonesia that plays an important role in supporting national food security and farmers’ income. One of the technologies introduced to improve maize productivity is Integrated Crop Management (ICM), which integrates several agronomic practices such as the use of improved varieties, optimal plant population, balanced fertilization, and integrated pest management. However, the level of ICM adoption among farmers is still varied, which may affect production performance and farm income. This study aimed to evaluate the implementation of Integrated Crop Management (ICM) technology and to compare the production and income of hybrid maize farmers who implement ICM technology and those who do not. The research used a quantitative survey approach involving hybrid maize farmers as respondents. Data was collected through field observations, interviews, and farm records. The results showed that the implementation of ICM technology significantly improved hybrid maize production and farmers’ income. Farmers implementing ICM technology achieved an average income of IDR 6,247,824 per hectare per planting season, while farmers applying non-ICM practices earned IDR 2,475,494 per hectare per planting season. The higher income was mainly driven by better crop management practices, including optimal plant population, balanced fertilization, and integrated pest management. These findings indicate that Integrated Crop Management technology contributes to improving production efficiency and farm profitability.

Preventing Brain Rot: Learning Using Youtube Video Media in Testing Students' Analytical Abilities
type: item
description: The phenomenon of brain rot, or the decline in analytical thinking skills due to passive consumption of digital content, is a new challenge in modern education. This study aims to test whether YouTube video-based learning improves students' analytical skills compared to conventional learning. The term "brain rot" has garnered widespread attention and has been discussed in both popular and academic literature recently; several articles and reviews have suggested a link between consuming short/shallow content and decreased concentration, cognitive overload, or reduced deep thinking. social media has positive impacts, such as a means for socializing, self-expression, seeking entertainment, obtaining information, building networks, and supporting the educational process, its negative side is also real. The research method used a quantitative approach with a quasi-experimental design. The study, conducted before and after the use of image learning media, significantly improved students' analytical skills. The results of the analysis of the analytical thinking skills test revealed changes in learning, indicating an increase. This means that the average sample remained in a normal brain state and did not experience a decline or brain decay in their analytical skills. The conclusion of this study is that targeted learning using YouTube videos can prevent brain rot by improving students' analytical skills.

Development of an Empirical Rainfall Estimation Model Using Himawari-8 Infrared Satellite Data in the Lombok River Basin
type: item
description: Flooding is a recurrent hydrometeorological hazard that occurs when rainfall intensity exceeds river channel capacity within a watershed. In the Lombok River Basin, limited rain-gauge density hampers the detection of localized high-intensity rainfall that can trigger flood events. This study develops a satellite-based rainfall estimation model using Himawari-8 infrared Cloud Top Temperature (CTT) integrated with surface atmospheric parameters, including relative humidity (RH), zonal and meridional wind components (u and v), and surface air pressure (P). Hourly rainfall observations from 15 rain gauges were used for site-specific calibration during two major flood events (6 December 2021 and 17 June 2022). A local nonlinear exponential regression model was fitted for each station using the Non-Linear Least Squares (NLLS) method, and model performance was evaluated using R², Nash–Sutcliffe Efficiency (NSE), RMSE, and RSR. Results indicate that thermodynamic predictors, particularly CTT and RH, provide the strongest empirical relationships with rainfall variability, while wind components contribute weaker at the statistical level. Overall performance varied spatially across stations, reflecting local terrain and microclimate effects. The proposed framework supports improved rainfall characterization in tropical island basins and can be adapted to other regions with appropriate local calibration.

Cowpea–Plantain Composite Flour: An Educational Approach to Dietary Intervention for Blood Pressure Management
type: item
description: Hypertension is a major risk factor for cardiovascular diseases and remains highly prevalent in Indonesia, particularly in South Kalimantan. This study aims to formulate a cowpea–plantain composite flour as a functional food with synergistic potential for blood pressure regulation. Composite flours were produced by processing raw materials through drying, milling, and sieving into formulations ranging from 10:90 to 90:10. Sensory attributes, including color, aroma, texture, and taste, were evaluated by 30 panelists, and the best formulation was determined using the De Garmo effectiveness index. Proximate composition, mineral content (potassium and sodium), and amino acid profiles were analyzed in an accredited laboratory. Sensory evaluation revealed that higher proportions of cowpea decreased taste acceptability, whereas plantain improved organoleptic characteristics. The optimal formulation was identified as KTPR8020 (80% cowpea : 20% plantain), which achieved a balanced profile of texture, aroma, and taste. Nutritional analysis indicated that cowpea increased protein (17.50%) and fat (1.56%) contents, while plantain contributed mainly to carbohydrates. The KTPR8020 formulation contained 5.98 mg/100 g potassium with a K/Na ratio of 7.1, supporting potassium-induced natriuresis. Amino acid profiling showed dominance of lysine, leucine, isoleucine, valine, and arginine, which are known precursors of bioactive peptides with ACE-inhibitory activity

Enhancing Nutritional Education Through the Development of Toddler Biscuits: A Focus on Mung Bean Flour and Patin Fish Paste as Effective Nutritional Interventions Against Malnutrition
type: item
description: This study aims to formulate toddler biscuits from mung bean flour and patin fish paste and to analyze their sensory quality, proximate content, amino acid profile, and fatty acid profile. Biscuits were prepared with varying ratios of mung bean flour and patin fish paste (10:90 to 90:10). Sensory quality tests were conducted using a hedonic scale scoring method with 30 trained panelists. The best formulation was selected using the De-Garmo test. Proximate analysis, amino acid profile, and fatty acid profile were performed on the best formulation and compared with standard toddler PMT biscuits. The KHIP5050 formulation (50% mung bean flour: 50% patin fish paste) was determined to be the best treatment based on the highest total De-Garmo score (3.33). Nutritionally, KHIP5050 biscuits had higher energy (479.45 kcal), protein (16.81%), and fat (27.77%) compared to standard PMT biscuits. The fatty acid profile was superior, with higher levels of MUFA and PUFA, and the presence of EPA, DHA, and AA, which were not detected in the standard biscuits. Toddler biscuits based on mung bean flour and patin fish paste, especially the KHIP5050 formulation, have significant potential as a nutrient-dense food product to address malnutrition in toddlers.
