Abstract

To improve the problem-solving skills of junior high school students, this study developed teaching materials in the form of e-Books based on the Science, Environment, Technology, and Society (SETS) approach. This approach was integrated with Banten local wisdom on the material of Elements, Compounds, and Mixtures. The development process was carried out using the ADDIE model which has five phases, namely Analyze, Design, Development, Implementation, and Evaluation. The quality of the e-Book was calculated through a validation process carried out by material experts, teaching material experts, and practitioners, while limited trials were carried out with students using a response questionnaire. The validation results proved that the e-Book had a "very valid" level of validity with a score of 90.90% in terms of content, appearance, presentation, and relevance to local wisdom. Meanwhile, student responses showed a "very positive" response with a percentage of 88.34%. This shows that the SETS-based e-Book integrated with local wisdom is worthy of being used as an alternative innovative teaching material in an effort to support students' problem-solving skills.

Abstract

The bark of the traditional plant, Archidendron bubalinum, known locally as kabau, exhibits promising qualities as a natural antibacterial agent. This research was conducted with two main objectives: (1) to evaluate the antibacterial efficacy of kabau fruit peel extract against two common pathogenic bacteria, Staphylococcus aureus and Escherichia coli, and (2) to design, validate, and assess the effectiveness of a research-based Microbiology E-Module in fostering students' critical analytical skills. The antibacterial capacity was tested using the paper disc diffusion method across a range of extract concentrations (5%, 10%, 20%, 40%, and 80%), using both pure water (aquades) and 2% dimethyl sulfoxide as carriers. Statistical analysis (one-way ANOVA, p = 0.020 < 0.05) indicated a notable difference in the zone of inhibition diameter across the various concentrations. The most potent antibacterial effect was observed at the 80% concentration with the aquades solvent, yielding inhibition zones of 3.97 mm against S. aureus and 8.42 mm against E. coli. These empirical results served as the core content for the innovative E-Module. The developed E-Module attained a high level of validity, achieving a CVR score of 1.00 from 5 expert validators, thus confirming its readiness for use. Subsequent evaluation during instructional application revealed a marked elevation in students' critical thinking abilities. Students in the Biology Department at FMIPA, Universitas Bengkulu, showed an initial mean pre-test score of 41.67, which surged to 88.00 in the post-test. This change resulted in an N-gain score of 0.79, positioning the improvement in the "high" category. Therefore, A. bubalinum extract is confirmed to hold antibacterial potential, and the E-Module is proven to be an effective educational tool for enhancing students' critical thinking competence.

Abstract

The escalating national energy demand and Indonesia's substantial reliance on fossil fuels underscore the imperative for the development of more sustainable alternative energy sources. Conversely, the magnitude of waste management challenges in DKI Jakarta persists, exerting an additional strain on the operational capacity of the Bantargebang TPST. Refuse Derived Fuel (RDF) is regarded as a strategic solution that can address the need for waste reduction and the provision of alternative energy. The objective of this study is to analyze the implementation of the RDF Plant Rorotan trial in DKI Jakarta using the implementation theory approach of Mazmanian & Sabatier and Allan McConnell's Policy Failure Theory model (2010). The methodological approach employed is descriptive qualitative, with data collection through documentation studies and observation.  The results of the study indicate that RDF Rorotan faces various technical, institutional, and social obstacles. According to the findings of Mazmanian & Sabatier's analysis, the characteristics of the problem, the clarity of policy objectives, coordination between relevant actors, and social environment support proved inadequate for achieving effective implementation. The presence of technical challenges, including elevated moisture content in waste, unpublished RDF quality, the ambiguity of off-takers, and complaints from residents regarding odors and health disturbances, suggests a suboptimal level of implementation readiness. McConnell's analysis corroborates the finding that RDF Rorotan is in a position of precarious success, which has resulted in policy failure in three areas: process, program, and politics. Indicators of early implementation failure include declining operational capacity, community resistance, and weakening policy legitimacy. The study's findings indicate that Rorotan RDF has not adequately fulfilled its designated role as a waste management solution and an energy alternative for national energy security. To optimize the potential of RDF, there is a necessity for improvements in quality standards, strengthened coordination, data transparency, and comprehensive environmental management strategies.

Abstract

Achieving learning objectives in a successful learning process cannot be separated from one of the students' internal factors, namely independence, especially learning independence. One of the development research that has been carried out by Kristina (2022) is to produce supporting products for teaching materials that can encourage student independence in the form of electronic modules (e-modules). Therefore, efforts are made to implement the E-module to train students' independent learning. This research aims to analyze the implementation of a scientific literacy-based e-module with the theme Let's Prepare for Disasters in training junior high school students' independent learning. The research subjects were class VII students of SMP Negeri 2 Kramatwatu who took science lessons using the e-module. The research method used is descriptive qualitative with data collection techniques in the form of observing learning implementation, observing students' independent learning activities, and learning independence questionnaires. The results of the research showed that the implementation of learning using e-modules went very well, reaching 93.4% at the first meeting and 96.4% at the second meeting. Observations of student learning independence showed an average observation result of 74.3% at the first meeting and 86.1% at the second meeting. Student learning independence questionnaire data supports observation results with an average of 81.1% in the "very good" category. These data show that the e-module based on scientific literacy with the theme Let's Prepare for Disasters is able to effectively train junior high school students' learning independence, as seen from the consistency between learning implementation, student activities in learning independence, and the results of students' perceptions through the learning independence questionnaire.

Abstract

Indonesia is one of the countries with the highest level of geospatial disaster risk due to its position on the Pacific Ring of Fire and its exposure to earthquakes, tsunamis, volcanic eruptions, floods, and landslides. The increasing complexity and frequency of disasters, exacerbated by climate change, demands a faster, more accurate, and integrated monitoring system. However, previous studies have focused more on the technical aspects of disaster monitoring without comprehensively examining the strategic role of satellite technology in strengthening Indonesia's national resilience. This gap is the basis for this study. This study aims to analyze the contribution of satellite technology in disaster mitigation and assess how satellite data integration can strengthen national resilience to geospatial threats. The method used is a systematic literature review of reputable international publications from 2014 to 2025 that discuss remote sensing technology, InSAR, damage mapping, early warning systems, and geospatial integration for disaster risk management. The results of the study show that satellite technology plays an important role in three main aspects: (1) real-time disaster monitoring through multisensor data capable of covering a wide area; (2) improving the accuracy of early warning systems for various geospatial disasters; and (3) strengthening national resilience through support for damage mapping, rapid response, strategic decision-making, and inter-agency coordination. The novelty of this research lies in the development of an integrative synthesis that links the use of satellite data with Indonesia's national resilience framework, as well as the affirmation of the need to integrate satellite technology into national disaster management policies. These findings have important implications for strengthening modern mitigation systems and adapting to the escalation of geospatial risks in the future.

Abstract

As the world’s largest nickel producer, Indonesia faces critical challenges in decarbonizing its nickel smelting sector while maintaining economic growth. This study addresses the lack of integrated assessments of carbon pricing impacts and green finance mechanisms in Indonesia’s nickel industry, using exclusively secondary data from government reports (BPS, MEMR), global databases (IEA, Global Carbon Atlas), and policy documents. A gate-to-gate Life Cycle Assessment (ISO 14044) reveals that Indonesian nickel smelters emit 14.8 tons CO₂-eq per ton of product (IEA, 2023), 25% higher than the global average. Economic modeling, based on nickel price trends (LME, 2020–2023) and carbon tax scenarios, indicates that a $40/ton CO₂ tax would raise production costs by 15%, reducing export competitiveness by 6.2% under current market conditions. Policy analysis highlights the feasibility of green bonds and fiscal incentives for renewable energy adoption, referencing successful cases in the Philippines (RE Law, 2022). These findings provide a data-driven framework for aligning Indonesia’s nickel industry with its 2060 net-zero target, emphasizing the role of secondary data in shaping low-carbon transitions for resource-rich economies.

Abstract

Lack of student understanding of learning materials often results in low learning outcomes. Therefore, selecting the right learning model is an important factor in achieving learning objectives, because it can help students understand the material more deeply. One approach that is considered effective and innovative is the Learning Cycle Type 7E model. This study aims to analyze the effect of implementing the Learning Cycle Type 7E model on students' critical thinking skills on the concept of Changes in Substances in Daily Life. The research method used was a quasi-experimental design with a nonequivalent control group design, which was carried out in one of the Public Junior High Schools in Serang City. The research sample was selected using a purposive sampling technique, consisting of 36 students in the experimental class and 36 students in the control class. Data collection was carried out using a test instrument in the form of HOTS (High Order Thinking Skills) questions that had passed validity and reliability tests. The results showed that the application of the Learning Cycle Type 7E model had a significant effect on improving the critical thinking skills of eighth grade students on the concept of changes in substances in daily life. Based on the results of the Independent Sample T-Test, a significance value (Sig. 2-tailed) of <0.001 was obtained, which is smaller than 0.05. In addition, the results of Group Statistics show that the average pre-test score of the experimental class was 37.54, while the control class was 34.78. Meanwhile, the average post-test score of the experimental class reached 41.51, higher than the control class which obtained an average of 36.59. These findings indicate that the Learning Cycle Type 7E model is effective in improving students' critical thinking skills.
