Abstract

The purpose of this study was to determine the potential of groundwater in Alasombo, Weru District, Sukoharjo Regency, Indonesia. The investigation has been carried out using geophysical methods that are integrated with surface geological data to obtain an interpretation of the hydrogeological control of the aquifer. The lithology of the aquifer is dominated by sandstone which controls its role as 2 types of aquifers, namely unconfined aquifers or free aquifers and semi-confined aquifers or semi-free aquifers. The geoelectrical section shows that the groundwater-carrying layer that functions as an aquifer is the sandstone layer in the second layer and sandstone in the base layer. As an artesian aquifer or a confined aquifer, sandstone aquifers have a water volume between 31.5 to 260 m3/day, in a northwest-southeast direction. In terms of the quality of the conductivity value of water in the field, below 1500 µs/cm is freshwater type groundwater that can be recommended as a source of clean water.

Abstract

Gerakan massa di Pedukuhan Cengkehan, Kalurahan Wukirsari, Pakanewon Imogiri, Kabupaten Bantul, merupakan longsoran yang terjadi sejak tahun 2019. Longsoran bergerak aktif, terutama pada musim hujan. Akibat perubahan iklim global, selain mempengaruhi pola dan intensitas hujan yang cenderung ekstrim, juga berpengaruh terhadap penyebaran pandemi dan penyakit Covid-19. Kegiatan pengabdian ini merupakan bagian desiminasi hasil penelitian penanganan gerakan massa di perbukitan dari gunung api purba Giriloyo dan sekitarnya. Potensi gerakan massa dapat dikenali dari pencermatan sifat fisik melalui pelapukan batuan. Perubahan sifat fisik menunjukan derajat pelapukan batuan dengan menggunakan metode Geological Society of London yang dipublikasi mulai tahun 1990. Dari hasil penelitian diperoleh informasi bahwa gerakan massa merupakan campuran material tanah dan batuan yang lapuk. Material ini berasal dari tinggian lembah Sungai Cengkehan. Batuan lapuk berupa batuan vulkanik yaitu tuf dan basalt yang berumur Miosen Awal. Lereng basalt di tebing Sungai Cengkehan bagian utara lebih berpotensi longsor daripada lereng basalt di tebing selatan. Bencana longsor pada lereng batuan lapuk tersebut lebih diwaspadai ketika terjadi hujan dan atau gempa. Kejadian hujan lebat dengan intensitas lebih dari 2 jam dapat memicu longsoran di lereng bagian utara.

Abstract

People who live in the Giwangan area, Umbulharjo District, Yogyakarta have public awareness in response to earthquake conditions. However, this is not the case for the migrant communities who lived after the earthquake in 2006. They are still inexperienced in dealing with earthquake situations. Some of them have not even interacted with local wisdom culture, especially in recognizing vibrations at the beginning of the earthquake. This is also the case in the neighborhood of education in Al Muyamman Giwangan. This community service aims to introduce ways of being responsive to the initial situation of the earthquake. The service method that has been carried out is through training in the manufacture and use of earthquake detectors for students. The results of the training showed that the participants were able to make an earthquake detector. This tool uses the sensitivity of the pendulum swing in a bottle against earthquake vibrations. Physically, the magnitude of the detected earthquake vibrations is like the ground surface vibration propagation when a truck is passed. Based on the approach to the magnitude of the Mercalli earthquake, the vibration is of magnitude 3 MMI (Modified Mercalli Intensity). This earthquake is equivalent to 4.3 on the Richter scale, still allowing people to save themselves. After the initial response to earthquake vibrations, it is necessary to be responsive when an earthquake occurs. This responsiveness is as understanding the existence of the assembly point location. We can carry evacuation efforts out if the location has exit access, release exits and supporting facilities that are in accordance with environmental conditions and local wisdom culture.

Abstract

Community service activities were carried out in Siten, Sumbermulyo Village, Kapanewon Bambanglipuro, Bantul Regency. The counseling was attended by members of the Family Empowerment and Welfare (PKK) group. Since the 2006 great earthquake, the public has been educated on earthquake response. However, they do not know the relationship between geological features and the value of local wisdom. Earthquakes of small scale and intensity are still being felt. Through service activities, the participants understand the emergency location planning model after the earthquake disaster. The introduction of local wisdom values ​​in the existence of several places becomes a means of educating the existence of geological features in the earthquake disaster area. Some of these places include springs, historical heritage sites, and isolated hill of Gunung Cilik. Based on the optimization of the results of previous research on geological features and Google Earth, an earthquake evacuation location is recommended. Evacuation locations are directed at limestone hills, 1 km to the west from the service location. Google Map can be used by participants to identify the evacuation route. In the discussion, a simulation of the evacuation was proposed to be carried out

Abstract

Stabilitas lereng merupakan aspek krusial dalam perencanaan infrastruktur, terutama di daerah dengan kondisi geologi kompleks. Penelitian ini berfokus pada analisis stabilitas lereng di Ruas Jalan Goa Jepang, Jelapan, Bantul, yang tersusun oleh batuan andesit dari Formasi Nglanggran dengan zona diskontinuitas geologi yang berpotensi menyebabkan ketidakstabilan lereng. Untuk mengevaluasi stabilitas lereng, digunakan metode Slope Mass Rating (SMR) yang dikembangkan dari Rock Mass Rating (RMR). Metode ini mempertimbangkan faktor koreksi orientasi diskontinuitas terhadap lereng guna memberikan hasil yang lebih representatif. Data diperoleh melalui survei geologi lapangan dan pengujian laboratorium, mencakup parameter geoteknik seperti kekuatan batuan, kondisi diskontinuitas, serta orientasi bidang lemah. Hasil penelitian menunjukkan bahwa nilai SMR berkisar antara 75,39 hingga 87,03, mengindikasikan kualitas massa batuan dalam kategori sedang hingga sangat baik. Korelasi antara RMR79 dan SMR lebih tinggi (R = 0,846) dibandingkan dengan RMR89 dan SMR (R = 0,419), menunjukkan bahwa SMR masih sangat bergantung pada RMR79. Namun, RMR89 dengan rentang nilai 25 hingga 30 terbukti lebih sensitif dalam mengidentifikasi potensi ketidakstabilan lereng dalam kategori buruk yang tidak terdeteksi oleh metode RMR79 dengan rentang nilai 43 hingga 72. Temuan ini menunjukkan bahwa kombinasi RMR89 dan SMR dapat menjadi pendekatan yang lebih akurat dalam mengevaluasi stabilitas lereng, terutama di daerah dengan geologi kompleks.

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.
