Hybrid Review: Research Trends Fe3O4-WTa37O95.487 Magnetic Nanocomposite as a Multifunctional Adsorbent for Decontamination of Industrial Dye Wastewater of Woven Fabrics
type: item
description: The increasing discharge of dye-contaminated wastewater from the textile industry poses serious environmental and health challenges, necessitating the development of efficient, sustainable, and reusable treatment materials. This study presents a hybrid review integrating a Systematic Literature Review (SLR) and bibliometric analysis to critically examine research trends, material design strategies, adsorption mechanisms, and existing limitations of magnetic nanocomposite adsorbents for textile dye wastewater treatment. Following the PRISMA 2020 guidelines, 30 peer-reviewed articles published between 2018 and 2025 were systematically selected for SLR from Scopus and SINTA databases and 200-500 articles for bibliometric analysis. Bibliometrics focuses on Scopus data (to identify global trends), while SINTA is used to strengthen SLR in the local context of the Indonesian textile industry. Bibliometric mapping using VOSviewer reveals a growing research emphasis on multifunctional materials, regeneration performance, and sustainability, while the SLR highlights a dominant focus on binary nanocomposite systems and single-dye adsorption studies under idealized laboratory conditions. A significant research gap is identified in the integration of complex tungsten–tantalum oxide phases with magnetic Fe₃O₄ matrices. Addressing this gap, this review identifies the integration of complex tungsten–tantalum oxide phases as a promising future research direction to overcome current limitations in chemical stability and improved resistance to harsh textile wastewater environments. The findings provide strategic insights for the design of next-generation magnetic adsorbents with improved industrial applicability and environmental sustainability.

Analysis of Integrated Science Process Skills in Elementary School
type: item
description: This study aims to analyze the ISPS owned by 4th-grade students at one of the Public Elementary Schools in Cilegon City, in the subject of IPAS on the five senses material. This study used a quantitative descriptive method whose sample consisted of 5 male students and 9 female students. The instrument used was a written test in the form of an essay consisting of 5 questions to measure students' science process skills. The results of the study showed that students' SPS was still low, as evidenced by the average test score of 51, which means the results of this study still indicate low abilities in ISPS. This study identified that integrated science process skills in grade 4 students are still low. These findings provide insight to teachers to design science learning activities that can actively involve students in learning activities. Thus, it is necessary to implement a learning model based on inquiry so that students can be actively involved in learning making learning more meaningful.

Enhancing High School Students’ Critical Thinking in Physics through a Virtual Classroom Critical Thinking Model: Supporting SDG 4 (Quality Education)
type: item
description: Developing students’ critical thinking skills (CTS) has become an essential focus in 21st-century education, particularly in digital learning environments. This study aims to examine the effectiveness of the Virtual Classroom Critical Thinking (VC2T) model in enhancing senior high school students’ CTS in physics learning. A pre-experimental one-group pre-test–post-test design was employed involving 56 eleventh-grade students from two science classes at a private senior high school in Surabaya, Indonesia. Data were collected using a CTS test based on Facione’s indicators: interpretation, analysis, evaluation, inference, and explanation, and a student response questionnaire. Data analysis involved normalized gain (n-gain), paired-sample t-test, and effect size calculations. The results indicate a statistically significant improvement in students’ CTS after the implementation of the VC2T model, with a medium n-gain and strong effect size. In addition, students expressed positive response toward the VC2T-based learning experience. These findings suggest that the VC2T model has strong potential as an effective online instructional approach for fostering critical thinking skills in physics learning.

Random Forest-Based Soil Mapping to Support Sustainable Watershed Management and SDG 15 (Life on Land): A Case Study of the Curahkemadu Micro Watershed
type: item
description: Soil characteristics in the Curahkemadu Micro Watershed are influenced by volcanic parent material and other soil-forming factors, including organisms, topography, climate, and time. This study aims to analyze the spatial distribution of soil up to the subgroup level and identify the dominant factors that shape it using a machine learning approach with the Random Forest (RF) algorithm. Field surveys were conducted at 14 Land Mapping Units (LMU) in the Bocek and Donowarih villages, followed by laboratory analysis of the physical and chemical properties of the soil. Soil classification followed the United States Department of Agriculture (2022) system, utilizing Geographic Information Systems (GIS) and ArcGIS Pro for spatial mapping. The classification results showed the existence of two main subgroups: Andic Humudepts (172.73 ha) and Typic Humudepts (577.73 ha). The spatial distribution of soil was strongly influenced by slope, sub-landform, and elevation, with variable importance values of 40%, 35.7%, and 24.3%, respectively. The RF model showed high performance with good accuracy (overall accuracy = 85.7% and Cohen’s Kappa = 0.69). This research provides an important basis for the optimal and sustainable management of watershed areas.

Analysis of Prospective Science Teachers’ Practicum Competencies in Promoting Sustainable and Quality Education (SDG 4)
type: item
description: Field practicum skills are a cornerstone of the professional competence of prospective biology teachers, yet their long-term developmental dynamics remain underexplored. This study aims to map the profile of field practicum abilities among Biology Education students at the Mataram University over a five-year period (2020-2024). Using a longitudinal quantitative approach, data were collected from 120 students through a structured, expert-validated questionnaire and analyzed using descriptive statistics and the non-parametric Kruskal-Wallis and Dunn's tests. The results indicate significant fluctuations in competency achievement: the highest average was in 2022 (79.28; SD=3.13) and the lowest in 2023 (65.93; SD=0.78). The Kruskal-Wallis test confirmed significant differences between years (χ² = 80.67; p < 0.05), with specific year pairs (e.g., 2022 vs. 2023) showing marked disparities. These findings reveal that field practicum ability is highly susceptible to curricular factors, institutional policies, and external disruptions such as extreme weather. The implication is that the development of prospective science teachers requires a learning ecosystem that is adaptive, evidence-based, and capable of proactively responding to environmental uncertainty.

Analysis Morphological Characters of Chalcorana chalconota (Schelgel, 1837) at Soraya and Ketambe Research Stations, Aceh
type: item
description: Chalcorana is a genus of amphibians that consists of species complexes which are difficult to distinguish morphologically. The difficulty in identifying species within this genus has prompted taxonomic research to utilize a more in-depth morphological approach in order to determine a more accurate taxonomic status and to examine the grouping of the Chalcorana genus originating from two different locations. This study used a principal component analysis (PCA) approach by measuring morphological characters. Based on the results of this study, it was found that different locations did not affect the variation in morphological characters, and therefore, no grouping was formed based on locality

Land Use Mapping Using Sentinel-2 Imagery and Volcanic Hazard Zonation for Sustainable Disaster Risk Reduction in the Mount Bromo Area, Probolinggo Regency, Indonesia
type: item
description: This study examines the spatial relationship between land use/land cover (LULC), volcanic hazard zones, and soil conditions in the Mount Bromo area of Probolinggo Regency, East Java, Indonesia. It aims to identify dominant LULC classes, quantify their overlap with volcanic hazard zones, and provide a spatial basis for risk-sensitive land-use planning. Sentinel-2 imagery was classified into four classes: vegetation, open land, agricultural land, and built-up area, and the results were evaluated using a confusion matrix. The classification achieved an overall accuracy of 81.97% and a kappa coefficient of 0.82, indicating reliable performance for regional-scale analysis. Agricultural land was the dominant class, covering 121,477.01 ha or 71.62% of the study area. Volcanic hazard zonation shows that 5,439.86 ha or 3.21% of Probolinggo Regency falls within Mount Bromo’s low-, moderate-, and high-hazard zones, including 941.66 ha or 0.56% in the high-hazard zone. Overlay analysis revealed that 212.39 ha of agricultural land and 16.33 ha of built-up area are located in the high-hazard zone, while 389.45 ha of agricultural land and 9.34 ha of built-up area remain in the moderate-hazard zone. Hazardous zones also spatially coincide with Mollic Andosols, indicating that volcanic risk overlaps with productive soils. These findings show that productive land and settlement-related land use are still not fully aligned with volcanic hazard conditions, highlighting the need for risk-sensitive spatial planning and adaptive land management.

description: This study examines the effectiveness of a dual-strategy intervention—SQ3R and concept mapping—in enhancing students’ comprehension and self-regulated learning (SRL) in an online distance learning context at Universitas Terbuka, Indonesia, contributing to SDG 4 (Quality Education). Using an explanatory sequential mixed-methods design, quantitative data were collected from 1.652 students through pretest–posttest measures in a one-semester course in the social sciences, followed by interviews with selected students and two instructors. Results indicate a statistically significant improvement in posttest scores (p < 0.001), although the effect size is small (d = 0.24). The strongest gains occurred in reading comprehension (SQ3R), with moderate improvements in concept mapping, while SRL gains remained limited. Qualitative findings suggest that students developed better reading structure, organization, and confidence; however, these did not fully translate into sustained metacognitive behaviors such as time management and reflective learning. This indicates that the intervention effectively improved cognitive and organizational skills but had limited short-term impact on deeper SRL habits. The study highlights the need for sustained scaffolding to develop SRL in distance education and supports the integration of structured learning strategies to improve learner autonomy.

Determination of the Effects of Exposure to Emissions from Chemical Industry on Health, Environment and Regulation
type: item
description: Rapid industrial growth in various regions of Indonesia has contributed significantly to the national economy. Pollution of air, water, and soil has become a critical concern when industrial activities are not managed in accordance with sustainability principles. This study aims to analyze the impact of emission exposure and operational activities of the chemical industry on public health, environmental conditions, and compliance with environmental regulations. A mixed-method approach was applied, combining quantitative and qualitative analyses. Quantitative data were obtained through air quality measurements and analyzed using linear regression and correlation techniques, while qualitative data explored regulatory compliance in greater depth. The findings reveal a positive correlation between increased emission exposure and higher incidences of respiratory disorders within the community. Environmental degradation was also evident, particularly in declining air quality and damage to surrounding vegetation. Although industrial practices generally comply with local environmental regulations, cases of Acute Respiratory Infections continue to rise. This indicates that regulatory compliance alone is insufficient to mitigate health risks. Therefore, stricter emission monitoring, improved transparency in environmental reporting, and enhanced community involvement are essential to support more sustainable and responsive industrial policies.

Effect of Botanical Pesticides on Inhibiting Colletotrichum sp. Causing Anthracnose in Avocado (Persea americana Mill.) In Vitro
type: item
description: Anthracnose caused by Colletotrichum sp. is a major postharvest disease of avocado (Persea americana Mill.) that leads to significant economic losses during storage. This study aimed to evaluate the antifungal efficacy of essential oil-based botanical pesticides derived from lemongrass (Cymbopogon nardus L.), cinnamon (Cinnamomum burmannii L.), and wild betel (Piper aduncum L.) against Colletotrichum sp. in vitro. The experiment was arranged in a Completely Randomized Design (CRD) with nine treatments and three replications, using essential oil concentrations up to 1000 ppm in both single and combined formulations. Antifungal activity was assessed based on colony diameter and fungal biomass, and data were analyzed using Analysis of Variance (ANOVA) followed by Duncan’s New Multiple Range Test (DNMRT). All treatments significantly inhibited fungal growth compared to the control. The smallest colony diameter was recorded in the lemongrass treatment (12.80 mm), with the highest inhibition rate of 85.77%. The lowest fungal biomass was observed in the cinnamon treatment (20 mg). These results demonstrate very strong antifungal activity of the tested essential oils.This study highlights the novelty of utilizing locally sourced essential oils as botanical pesticide formulations targeting Colletotrichum sp., suggesting their potential as environmentally friendly alternatives for sustainable postharvest disease management.

Carrying Capacity Assessment for Strengthening Landscape Conservation Governance: A Case Study of the Sentarum Lake Sub-Watershed
type: item
description: A landscape carrying capacity assessment serves as a critical tool for strengthening sustainable natural resource governance within socio-ecological systems. This study aimed to evaluate the carrying capacity status of the Sentarum Lake Catchment Area and identify key ecological and socioeconomic vulnerabilities. The analysis was conducted using a multi-criteria index-based approach aligned with the Indonesian Minister of Forestry Regulation No. P.61/Menhut-II/2014, integrating cross-sectoral data across five dimensions: land condition, water regime, socioeconomic conditions, water infrastructure, and land use patterns. The results showed that the carrying capacity was classified as “good,” with an index value of 78.00. Nevertheless, a phenomenon of pseudo-hydrological stability was identified, in which stable flow regimes (flow regime coefficient = 0.50) and high water availability (water use index = 0.50) masked functional degradation within the system. This condition was reflected in a high annual runoff coefficient (1.50) and increasing flood frequency (1.25), indicating declining infiltration capacity. These pressures were further exacerbated by the limited proportion of natural vegetation within protected areas (45.10%) and high socioeconomic vulnerability (poverty level index = 1.50). Overall, the findings indicate a fragile equilibrium in which apparent ecological stability conceals emerging hydrological and socioeconomic risks. Without adaptive and integrated management interventions, the system is likely to shift toward structural degradation. Therefore, strengthening landscape governance requires ecosystem-based spatial planning, nature-based mitigation strategies, and inclusive local economic development to enhance long-term resilience.

Detection of Adulteration in Virgin Coconut Oil (VCO) Based on Arduino with Machine Learning Algorithms through Dielectric Property
type: item
description: The mixing of pure coconut oil (VCO) with cheaper vegetable oils has negative impacts on both consumers and producers. This study aims to develop a method for detecting VCO adulteration using an ESP32-based dielectric sensor combined with a Random Forest classification algorithm. The research employed an experimental design using 225 samples, including pure VCO, canola oil, corn oil, and various mixture ratios, each measured with five repetitions. The results show that pure VCO exhibits the highest capacitance values (58.4–62.4 pF), followed by canola oil (44.8–47.8 pF) and corn oil (43.2–46.6 pF), indicating clear differences in dielectric properties related to fatty acid composition. ANOVA analysis confirmed a significant difference between pure VCO and adulterated oils (p < 0.05). The Random Forest model achieved an accuracy of 53–58% for 15-class classification, while binary classification (pure vs adulterated oil) reached more than 90% accuracy. This finding is discussed in terms of the effectiveness of dielectric sensing combined with machine learning for distinguishing oil authenticity. In conclusion, the proposed system provides a fast, low-cost, mobile, and user-friendly solution for VCO quality monitoring, with potential applications in supply chain control and consumer protection.

Bayesian Tobit Model for Handling Left-Censored in Water Quality Assessment: A Case Study of Sunda Strait, Indonesia
type: item
description: As an archipelagic nation, Indonesia relies heavily on coastal activities that may affect marine water quality, yet studies addressing this issue remain limited, particularly in the presence of left-censored data. This study aims to evaluate an appropriate method for handling left-censored data in water quality assessment using the CCME-WQI, with a case study in the Sunda Strait. A Bayesian Tobit model was applied to account for left-censored observations and integrated with the CCME-WQI framework. For comparison, conventional substitution methods and exclude left-censored were also used. The performance of approaches was assessed based on their ability to produce reliable water quality index estimates. The results indicate that the Bayesian Tobit model provides more robust estimates than substitution methods, as it incorporates uncertainty through credible intervals and reduces potential bias. The estimated water quality index ranged from 83.8 to 92.1, classifying the water quality as “good.” In conclusion, the Bayesian Tobit model is a more reliable approach for handling left-censored environmental data and improving water quality assessment. This method is particularly relevant for routine monitoring and can be extended to other fields with similar data characteristics.

Flood Disaster Mitigation Strategy in Kuala Lumpur
type: item
description: In Malaysia, flash floods or major floods often occur in the capital city of Kuala Lumpur, flooding is a natural phenomenon that occurs when the volume of water flowing in rivers, lakes, or other bodies of water overflows onto land. The purpose of this study is to determine the level of flood vulnerability and determine flood mitigation strategies. This research is descriptive quantitative, which describes the phenomenon of flood disasters through mapping results. To produce a map of flood-prone areas, mapping was carried out using ArcGIS with a scoring method to see flood hazard vulnerability. The results of the flood vulnerability mapping study in Kuala Lumpur show critical conditions with almost 90% of the total area of 27.195.47 hectares categorized as vulnerable to very vulnerable to flooding. Analysis using the Analytic Hierarchy Process (AHP) method identified three priority mitigation strategies, namely Regulation (57.7%) as the highest priority which includes policy enforcement and implementation of MSMA, followed by Education (25.8%) to increase public awareness and preparedness, and Conservation (16.5%) through ecological rehabilitation and green infrastructure. The integration of these three strategies is necessary to create a comprehensive and sustainable flood mitigation framework, taking into account the high urbanization and climate change that continue to increase flood risks in the Kuala Lumpur metropolitan area.

Management of Archery-Based Sport Games to Improve Numeracy and Attention in Elementary School Students: A Sequential Exploratory Mixed-Methods Study
type: item
description: Competency-based learning transformation requires the strengthening of numeracy and attention from elementary school through meaningful, safe, and measurable learning experiences. This study aimed to synthesize scientific evidence on the management of archery-based sport games and to verify its practical relevance through primary questionnaire data. A sequential exploratory mixed-methods design was employed. The first phase consisted of a systematic literature review conducted according to the PRISMA guidelines. A Scopus search identified 170 records, which were screened based on publication year, article type, language, access status, primary data orientation, and relevance to archery, target sports, physical education games, attention, and numeracy integration. A total of 25 articles were included in the narrative synthesis. The second phase was conducted using a five-point Likert-scale questionnaire administered to 25 elementary school physical education students who had experience in archery courses. The results showed very high internal consistency, with Cronbach’s alpha = 0.945. The overall item mean was 4.47 out of 5, the mean total score was 120.80 out of 135 with SD = 10.81, and 96.74% of responses were categorized as positive. The safety and readiness construct obtained the highest mean score (M = 4.75), followed by attention enhancement (M = 4.49), motivation and engagement (M = 4.49), game-based learning design (M = 4.42), numeracy integration (M = 4.38), and implementation feasibility (M = 4.34). The integration of both findings indicates that archery-based games have the potential to serve as a safe, engaging, and measurable physical education strategy for training focus and embedding contextual numeracy activities. However, claims regarding numeracy improvement still require direct experimental testing with elementary school students.

Objective: This study aims to investigate the effect of Problem-Based Learning (PBL) and learning motivation on elementary school students' scientific literacy, and to test the interaction between the two variables. Method: This study used a quasi-experimental design with a pretest–posttest nonequivalent control group. The sample consisted of 60 fourth-grade students at Mekar Bakti Public Elementary School, Indonesia, divided into two classes (n=30 each). Scientific literacy was measured using a PISA-oriented essay test (scale 0–100), while learning motivation was assessed with a 40-item Likert questionnaire (α=0.884). Data were analyzed using a 2×2 factorial ANOVA and Tukey HSD follow-up test. The findings showed that: Students in the PBL class achieved higher scientific literacy than those in the conventional class (M=78.63 vs 68.57; p=0.001); Students with high motivation outperformed students with low motivation (M=76.67 vs 70.53; p=0.039); There was a significant interaction between PBL and learning motivation (F (1.56) =17.23; p<0.001); The post-hoc test results showed that the PBL-high motivation group performed significantly better than the other three groups. These findings indicate that the PBL model is most effective when student motivation is high.

Academic Self-Efficacy, Achievement Motivation, and Academic Resilience as Predictors of Science Learning Outcomes among Students in the Elementary School Teacher Education Programme
type: item
description: Science learning outcomes among elementary school teacher education students are determined not only by mastery of content but also by psychological factors that influence engagement, persistence, and academic success. This study aimed to analyse the effects of academic self-efficacy, achievement motivation, and academic resilience on the science learning outcomes of students in the Elementary School Teacher Education Programme. The study employed a quantitative approach with a correlational survey design. The respondents comprised 136 students. Data were collected through a four-point Likert-scale questionnaire, with 16 items for each variable, and were then analysed using multiple linear regression. Instrument quality indicated that all items were valid and reliable, with Cronbach’s alpha values of 0.951 for academic self-efficacy, 0.953 for achievement motivation, 0.962 for academic resilience, and 0.979 for science learning outcomes. The findings showed that the three predictors simultaneously had a significant effect on science learning outcomes with R = 0.909, R² = 0.826, and F(3,132) = 209.460, p < 0.001. Partially, academic self-efficacy had a significant positive effect, academic resilience emerged as the most dominant predictor, whereas achievement motivation had no significant effect after being controlled together with the other variables. These findings underscore that improving the science learning outcomes of Elementary School Teacher Education students should focus on strengthening academic confidence and learning resilience through challenging, supportive, and sustainable learning experiences.

Investigation of High School Students’ Conceptual Understanding of Light Waves: Survey in West Java
type: item
description: Conceptual understanding is key to learning. It serves as the groundwork that enables students to apply concepts and build higher-order skills. However, previous studies have shown that students’ conceptual understanding of light waves remains limited, and comprehensive data across multiple regions are still lacking. This study investigates students’ conceptual understanding of light waves in West Java. The sample comprised 189 twelfth-grade students who had completed instruction on light waves, selected using a random sampling technique. Employing a survey design with a quantitative descriptive approach, data were analyzed using Rasch Model techniques. The instrument used was a 29-item multiple-choice Light Phenomena Conceptual Assessment (LPCA) which has been validated and reported as reliable. Based on person logit scores, results indicate that 58.73% of students fall into the low-ability category, 26.98% into the medium category, and 14.29% into the high category. These results indicate that majority of students have not yet attained an adequate level of conceptual understanding and still experience difficulties in understanding light wave concepts, which may limit their problem-solving abilities. These outcomes can inform educators and researchers in designing instructional strategies and learning media to more effectively teach light wave concepts and thereby improve students’ conceptual grasp.

Integrating Science and Entrepreneurial Character Among Islamic Boarding School Students Through an Integrated Agribusiness Model
type: item
description: This study analyzes the integration of scientific knowledge and entrepreneurial character development among santri (Islamic boarding school students) through an integrated agribusiness model at two pesantren in East Ogan Komering Ulu, Indonesia. Using a qualitative case study approach with interviews, observation, and document analysis, findings reveal that both institutions systematically combine scientific agricultural practices—such as hydroponics, organic cultivation, and sustainable resource management—with Islamic ethical principles like amanah (trustworthiness) and muamalah fiqh. Three core strategies emerged: value-infused mentorship, reflective practice, and community-engaged learning, which collectively cultivate a distinctive "santripreneur" identity wherein scientific literacy, economic agency, and spiritual accountability mutually reinforce one another. Santri demonstrated enhanced entrepreneurial self-efficacy, innovation orientation, evidence-based decision-making, and ethical reasoning. The study concludes that integrated agribusiness models effectively internalize entrepreneurial character when grounded in experiential learning, science-based pedagogy, and value-based instruction. However, scalability requires addressing systemic constraints—including technological access, market linkages, and educator capacity—through coordinated multi-stakeholder support. These insights offer a replicable framework for Islamic educational institutions seeking to cultivate ethically grounded, scientifically literate, and economically resilient graduates capable of contributing to sustainable rural development.
