Abstract

Meeting clean water needs in densely populated areas such as Ngoresan, Surakarta City, is a major challenge, especially during the dry season when well discharge declines. This community service initiative aims to enhance clean water resilience in Ngoresan through the application of groundwater drilling technology informed by geological studies. The activities include site survey, equipment installation, drilling, aquifer identification, water quality analysis, community education, and joint evaluation. Drilling identified a productive aquifer at a depth of 25.7 meters within Merapi volcanic rock, with the final well reaching 62.5 meters. Water quality analysis confirmed it is safe for consumption. Community participation in education and facility maintenance strengthens the sustainability of the program. This initiative not only provides a reliable water source but also fosters awareness of groundwater conservation and the risks of over-extraction, thereby enhancing local resilience in water availability.

Abstract

The lack of mineralization research on metamorphic rocks in Java, especially in the Jiwo area, is part of the research interest. The host rock of ore mineralization in the Jiwo area is Cretaceous metamorphic rock located in the hilly area of Jiwo, Klaten, Central Java. The presence of chlorite, actinolite, quartz, epidote, and garnet minerals indicates the metamorphic facies of greenschist. Meanwhile, the presence of glaucophane, quartz, and epidot minerals is a metamorphic facies of blueschist. The metamorphic rock research method was carried out in several stages: 1. Observation; 2. Field data collection, including mapping of metamorphic rock distribution, general geological conditions and rock sampling; and 3. Laboratory analysis. Laboratory analysis testing consists of petrography, ore microscopy, geochemistry (AAS), and fluid inclusion. Alterations that develop in the researched area are in the form of propylitic (chlorite, calcite, epidote), argillic, and silicification (quartz, graphite, calcite, carbonate minerals). Ore microscopy analysis has identified the presence of mineral sulfide such as pyrite, chalcopyrite, bornite, galena, and covellite. In addition, galena was found covered with chalcopyrite. Based on AAS analysis on mineralized metamorphic rocks, Au levels are 0.001 - 0.008 g/t, Ag 0.1 - 2.4 g/t, Cu 4 - 75 g/t, Zn 14 - 166 g/t, and Pb 11 - 60 g/t. The inclusion of fluid from the discordant vein was obtained with a homogenization temperature (Th) of 312 - 435 0C, with a salinity of 1.95 - 5.05 wt. % eq. with isothermal mixing and heating depressurization conditions. The isothermal mixing process is a mixture of meteoric fluids and metamorphic fluids. Meanwhile, heating depressurization occurs during subduction, so that the temperature is relatively high. The homogenization temperature (Th) of the concordant vein ranges from 168.5 - 296.55 °C, with a salinity of 1.95 -12.6 wt% NaCl eq. A salinity of 12 wt% NaCl is formed due to liquids that are aquos trapped at high pressure and temperature conditions and the devolatilization process that occurs during subduction. Based on the plotting of the homogenization temperature range and the salinity of fluid inclusion, which is 168.5 - 4350C and 1.95 - 12.6 wt% NaCl eq, the type of deposits in the study area is in the range of Au lode or orogenic deposits. The existence of two homogenization clusters in the Jiwo Hill is estimated to be part of the process of forming the blueschist facies with greenschist which is shown in the retrograde actinolite in the glaucophane epidote schist rock which is part of the blueschist facies.

Abstract

Stabilitas lereng batuan merupakan faktor krusial dalam mitigasi risiko longsor, khususnya pada kawasan perbukitan vulkanik yang tersusun oleh massa batuan terdiskontinu dan terlapukkan. Ruas Jalan Goa Jepang, Kabupaten Bantul, berada pada lereng curam yang berkembang di lava andesit dan dipengaruhi oleh struktur geologi aktif, sehingga rentan terhadap ketidakstabilan lereng. Penelitian ini bertujuan mengevaluasi pengaruh pelapukan massa batuan, yang diwakili oleh berat unit batuan, terhadap nilai Rock Mass Rating (RMR) dan implikasinya terhadap kestabilan lereng. Pendekatan kuantitatif–statistik diterapkan melalui survei lapangan dan pengujian laboratorium pada tujuh lokasi. Kualitas massa batuan dievaluasi menggunakan RMR, sedangkan hubungan antar parameter dianalisis melalui grafik sebar dan regresi linier. Hasil menunjukkan nilai RMR berkisar 25–72, mencerminkan variasi kualitas massa batuan dari buruk hingga baik. Analisis statistik mengindikasikan hubungan sedang antara berat unit dan RMR (R² = 0,468), meskipun tidak signifikan secara statistik. Temuan ini menegaskan bahwa pelapukan mempengaruhi kestabilan lereng terutama melalui degradasi kondisi diskontinuitas, kekuatan batuan, dan RQD. Hasil penelitian ini mengindikasikan bahwa integrasi parameter pelapukan dalam kerangka klasifikasi RMR dapat meningkatkan keandalan evaluasi stabilitas lereng batuan pada lingkungan vulkanik terlapukkan.

Abstract

This community service program was carried out at the Wimalandaru Waste Bank in Karanggayam Hamlet, Catur Tunggal Village, Sleman, to improve waste management effectiveness through the implementation of a web-based waste bank application. The digital system implementation was able to address the partner’s main problems, particularly the inefficiency of manual record-keeping, limited structured data, and low community participation. Digitalization was conducted for 158 customers, with women comprising 65.82%, along with the documentation of 41 waste categories complete with prices and statuses, which improved transaction accuracy and service speed. The success of the program was influenced by the active participation of the management team, strong motivation among women’s groups, and the availability of digital devices. However, challenges were still encountered, especially those related to variations in digital literacy and network constraints. Therefore, further development was recommended through digital capacity-building training, strengthening network infrastructure, and expanding women’s empowerment in waste sorting and recycling-based entrepreneurship. With continuous monitoring, the application was expected to serve as a model for adaptive and sustainable technology-based waste bank management at the village level.

Abstract

Community-based plastic waste management continues to face challenges related to the large volume of recyclable materials, resulting in inefficient storage, distribution, and logistics management. These conditions reduce operational effectiveness and limit the economic benefits obtained by waste bank managers. This community service program aimed to enhance the capacity of the Wimalandaru Waste Bank managers through the transfer of waste compactor technology and technical assistance for its application in plastic waste management. The program employed a participatory approach based on the Participatory Action Learning System (PALS), consisting of initial condition assessment, technology implementation, operational training and socialization, technical mentoring, and monitoring and evaluation activities. The results showed that the managers were able to independently operate the waste compactor, apply occupational safety procedures, and manage the plastic compaction process more effectively. The implementation of the compactor transformed plastic gallons and bottles into compact cubic blocks, improving storage and transportation efficiency. The technology contributed to a reduction in logistics costs by 96.65% for plastic gallons and 93.33% for plastic bottles, resulting in substantial improvements in operational efficiency. Furthermore, the mentoring activities enhanced both the technical and managerial capacities of the managers in equipment operation, logistics management, storage arrangement, and equipment maintenance. The program demonstrates that technology transfer combined with continuous mentoring can improve operational efficiency, strengthen the institutional capacity of community-based waste banks, and support more effective, safer, and sustainable plastic waste management practices.
