Abstract

Life in the 21st century is full of challenges and problems that need to be solved in order to survive in global competition. This condition makes science education in the 21st century must be able to produce graduates who are not only good at knowledge, but also have critical thinking skills, creativity, collaboration, communication, not to mention problem solving. The purpose of this study was to analyze the effectiveness of e-modules based on case methods to improve the problem solving skills of prospective science teachers. This research uses RnD with the ADDIE model. Then e-module based on case methods that has been developed is implemented in basic science learning with a quasi-experimental design Nonequivalent control group design. Data analysis was conducted with the validity, characteristics, and effectiveness of e-modules based on case methods. The results showed that the e-module based on case methods was valid for use with a value of 0.98. The implementation of e-modules showed an increase in pretest and posttest results with an experimental class n-gain score of 0.85 with high criteria, while the control class n-gain score was 0.68 with moderate criteria. The conclusion of this study is that the e-module based on case methods is effectively used to improve the problem solving skills of prospective teacher students in Basic Science courses.

Abstract

This study aims to analyze the impact of land use changes on the carrying capacity of the protective function of the Babon Watershed (DAS Babon) and its relation to flood events in the area. The research employs a quantitative approach using satellite imagery data from 2015 and 2023, processed with Geographic Information Systems (GIS) to map land use changes and the carrying capacity of the watershed's protective function. The results indicate significant land use changes, particularly the conversion of agricultural land into residential and industrial areas, which has reduced the extent of water infiltration zones and natural vegetation. The decline in the carrying capacity of the protective function of the Babon Watershed has increased flood risks, especially in downstream areas exposed to high surface runoff. The analysis of the protective function's carrying capacity (DDL) reveals a degradation in protective quality in several districts, with lower DDL values observed in 2023. The use of impervious materials such as concrete and asphalt exacerbates drainage quality and worsens flood risks.

Abstract

Kecamatan Bojong, Kabupaten Tegal merupakan wilayah yang terdapat kawasan lindung berdasarkan Rencana Tata Ruang Wilayah (RTRW). Perubahan penggunaan lahan di wilayah ini terjadi akibat pertumbuhan penduduk dan meningkatnya aktivitas ekonomi. Hal ini dapat memberikan ancaman lingkungan termasuk di sekitar mata air. Kajian ini bertujuan untuk menganalisis perubahan tutupan lahan di Kabupaten Tegal dan sekitar 13 mata air utama di Kecamatan Bojong menggunakan metode Sistem Informasi Geografis (SIG). Data berupa citra satelit tahun 2015 dan 2024 diinterpretasikan secara visual untuk menghasilkan peta perubahan tutupan lahan. Hasil penelitian menunjukkan bahwa terjadi perubahan penggunaan lahan dari tahun 2015–2024 dengan peningkatan lahan permukiman sekitar 58,58 ha, penurunan lahan hutan rakyat sekitar 9,33 ha, penurunan lahan kebun campuran sekitar 0,65 ha, dan penurunan lahan sawah sekitar 43,19 ha. Terdapat 13 mata air di lokasi penelitian. Namun, pesatnya perubahan lahan di Kecamatan Bojong membawa tantangan. Area sempadan mata air yang semestinya menjadi zona lindung kini beralih fungsi seperti pada Mata Air Pekewon dan Banyumudal. Hal ini mengancam kelestarian mata air dengan mengurangi area resapan dan meningkatkan pencemaran yang berdampak pada kualitas air serta kesehatan masyarakat yang bergantung padanya. yang menghadapi tekanan lingkungan signifikan akibat perubahan ini, sehingga diperlukan strategi konservasi yang tepat untuk menjaga keberlanjutan sumber daya air dan fungsi ekosistem.

Abstract

Penelitian ini menganalisis perubahan penggunaan lahan pertanian di Kota Pekalongan selama periode 2015–2023 serta mengevaluasi dampaknya terhadap daya dukung pertanian. Studi ini dilatarbelakangi oleh tekanan urbanisasi, pembangunan infrastruktur, dan alih fungsi lahan yang signifikan. Data geospasial dari citra Landsat diolah menggunakan Sistem Informasi Geografis (SIG) untuk mengidentifikasi pola perubahan lahan, yang dikategorikan menjadi lahan non-pertanian, pertanian, dan kawasan sungai. Hasil penelitian menunjukkan bahwa luas lahan non-pertanian meningkat sebesar 14,41% dari 2.632,94 hektar menjadi 3.012,00 hektar, sementara lahan pertanian menurun sebesar 20,25% dari 1.967,46 hektar menjadi 1.568,49 hektar. Perubahan ini dipengaruhi oleh pertumbuhan penduduk, banjir rob, dan perkembangan sektor industri. Penelitian ini diharapkan dapat menjadi dasar bagi perencanaan tata ruang yang berkelanjutan untuk melindungi lahan pertanian produktif dan menjaga keseimbangan ekosistem di Kota Pekalongan.

Abstract

Waste management in Indonesia is still dominated by open burning and landfilling, causing environmental and health problems. In Jetak Village, Getasan District, Semarang Regency, located in the rural highlands of Mount Merbabu, organic waste dominates household waste streams. Although a TPS3R facility has existed since 2022, its operation remains suboptimal due to low community participation and odor issues. This condition highlights the urgent need for innovative, community-based solutions. Black Soldier Fly (BSF, Hermetia illucens) farming offers an effective alternative, capable of reducing organic waste by 50–60% while producing valuable by-products. This community service program targeted village officials, farmer groups, women’s groups, youth, and TPS3R managers. Activities included awareness sessions on circular economy, training in BSF cultivation, field demonstrations using appropriate technology, digital marketing workshops, and operational assistance at TPS3R. Impact was assessed through participant questionnaires and scenario modeling of household-level BSF adoption based on waste generation data from SIPSN (2025) and BPS (2025). Twenty-five participants engaged actively throughout the program. Evaluation showed 100% agreement that BSF is effective for organic waste management, with 89% willing to adopt it at home. Products such as fresh and dried larvae and frass were successfully introduced, with estimated market value up to IDR 52,000/kg. Scenario analysis indicated potential reductions of 89–268 tons of organic waste annually and mitigation of 2.6–7.8 tons CO₂e, depending on adoption rates. The program proved that BSF technology is feasible, socially acceptable with proper education, and economically promising. It strengthened local waste management capacity, supported income generation, and contributed to circular economy transition while aligning with SDG 12 and Indonesia’s low-carbon development goals.

Abstract

Many countries are transitioning from conventional energy to renewable energy sources. This transformation requires support through socialization and training activities targeting all sectors of society, including educators in schools. The Al-Hidayah Waqaf Foundation in Thailand is an educational institution with educators who have limited knowledge regarding the implementation of renewable energy as part of energy diversification efforts. Collaborative activities were conducted with the Al-Hidayah Waqaf Foundation in Thailand through socialization and training on renewable energy. The outcomes of these activities provided educators with increased knowledge, information, and perspectives on renewable energy.
