Community Service (PkM) aims to provide understanding to the community in the Depok area, which has been affected by the Hepatitis A pandemic outbreak, regarding the importance of maintaining the distance between septic tanks and drilled wells in order to prevent diseases caused by contaminated water. The method used is to provide socialization of the Minister of Health Regulation no. 3 of 2014 and SNI 2398:2017 to PKK women, cadres, in Gandul Village, Cinere Depok District, regarding septic tanks, manufacturing requirements and their distance to clean water sources. Based on the pre and post tests carried out, it showed that all PkM participants already understood the importance of the requirements for making speptic tanks and setting the distance between the septic tank and clean water wells. However, to apply in the field still requires assistance. The implications of this PkM provide an opportunity for extension workers to research further about groundwater conditions in Gandul Village in order to provide solutions for the community to anticipate the presence of existing fecal waste so as not to pollute the existing ground water

Reservoir vulkaniklastik di indonesia merupakan reservoir dengan produksi yang signifikan. Rekah alami adalah faktor terpenting dalam menentukan kualitas dan kuantitas dari reservoir vulkaniklastik untuk diungkap lebih detail. Log image dan data wireline log dapat digunakan untuk memberikan informasi zona rekah alami, dan rekahan konduktif serta rekahan resistif. Pada kasus penelitian ini, hadir tuf dengan rekah alami sebagai porositas sekunder. Intensitas rekahan dan apertur menjadi parameter penting untuk menghitung nilai porositas rekahan pada masing-masing zona. Pengukuran langsung pada log image dapat mendeteksi intensitas rekahan dan apertur dimana dicirikan oleh sinusoidal yang dibentuk dari resistivitas ataupun kontras akustik. Perkalian antara intensitas rekahan dan apertur digunakan untuk menghitung porositas rekahan. Bulk modulus juga digunakan sebagai konstrain untuk mendistribusikan nilai I*A pada sumur yang tidak memiliki image log. I*A yang tinggi menaikan nilai bulk modulus, dan nilai I*A naik pada area yang dekat dengan lipatan dan yang dekat dengan patahan.

Daerah penelitian berada pada daerah Kecamatan Karangpucung, Kabupaten Banyumas, Provinsi Jawa Tengah. Penelitian ini bertujan mengetahui fasies dan sistem pengendapan pada daerah penelitian. Terutama pada kondisi geologi Formasi Halang yang dikenal juga sebagai daerah lingkungan pengendapan laut dalam atau turbidit. Pengambilan data dilakukan dengan metode stratigrafi terukur, ditunjang dengan analisis petrografi dan mikropaleontologi Formasi halang pada daerah penelitian didominasi oleh perselingan batupasir dan batulempung atau batulanau. Hasil kajian endapan turbidit dari formasi halang dapat disimpulkan terendapakan pada sistem lobes yang membentuk kipas laut dalam, mulai upper fan dan suprafan lobes on mid fan. Lapangan penelitian ini memiliki 4 asosiasi fasies, yaitu: (1) Fasies batupasir berukuran sedang sampai halus (AF1); (2) Fasies perselingan breksi dengan batupasir tuffaan (AF2); (3) Fasies perselingan batupasir berukuran kasar sampai sedang dengan batulempung (AF3); (4) Fasies batupasir berukuran sedang sampai halus tuffaan(AF4).

Cekungan Sumatera Tengah merupakan cekungan yang mengalami rangkaian deformasi yang mempengaruhi lapisan batuan sehingga memiliki struktur bawah permukaan yang kompleks, struktur sesar memiliki peran sebagai pengontrol distribusi dan akunulasi hidrokarbon. Struktur “SUPRAN” dikontrol oleh struktur sesar normal dan sesar mendatar yang dapat bersifat sebagai perangkap hidrokarbon ketika memiliki sealing capacity tinggi. Penelitian ini menganalisis karakteristik sesar normal menggunakan metoda shale gouge ratio (SGR), data yang digubakan adalah data seismik 2D dan data sumur. Analisis dilakukan membuat Allan Map, Throw Map, dan SGR Map pada bidang sesar. Hasil analisis menunjukkan dominasi kesehadapan sandstone juxtapose terhadap sandstone dengan nilai SGR dominan berkisar pada 10%-25%. Hasil penelitian sesar normal pada struktur “SUPRAN” bersifat leaking. Kata-kata kunci: Analisis Sekatan Sesar, Shale Gouge Ratio, Juxtaposition, Sealing Capacity, Cekungan Sumatera Tengah

Lithofacies classification is a process to identify rock lithology by indirect measurements. Usually, the classification is processed manually by an experienced geoscientist. This research presents an automated lithofacies classification using a machine learning method to increase computational power in shortening the lithofacies classification process's time consumption. The support vector machine (SVM) algorithm has been applied successfully to the Damar field, Indonesia. The machine learning input is various well-log data sets, e.g., gamma-ray, density, resistivity, neutron porosity, and effective porosity. Machine learning can classify seven lithofacies and depositional environments, including channel, bar sand, beach sand, carbonate, volcanic, and shale. The classification accuracy in the verification phase with trained lithofacies class data reached more than 90%, while the accuracy in the validation phase with beyond trained data reached 65%. The classified lithofacies then can be used as the input for describing lateral and vertical rock distribution patterns.

Hydrocarbon reserves are one of the main points that are very important in the sustainability of the productivity of an oil and gas field. This important point is greatly influenced by several parameters that can be obtained by various measurements and analysis. One of the most influential parameters in the analyses of the amount of hydrocarbon reserves in a reservoir is the water saturation value. The water saturation parameter will also be greatly influenced by the electrical parameters of the fluid-containing rock in the reservoir. Sometimes the electrical parameters of this rock, in this case resistivity becomes one of the benchmark parameters, whether the zone or reservoir has potential or is interesting to be developed or produced. However, there are several reservoirs or zones that experience low resistivity effects which will give an initial indication that the zones or reservoirs are not attractive or have no effect on development. In this Z field, there is a zone that experiences low resistivity effects, making this zone unattractive for production. So to be able to make these zones attractive for production, an identification analysis was carried out on Zones A and B in this Z field to determine the type or type of fluid from the two zones. The initial analysis was carried out petrographically from rock sample incisions at certain depths in Zones A and B so that it is known that the cause of the low resistivity effect in the two zones is the presence of pyrite minerals and illite clay which are the main causes of the low resistivity effect. Furthermore, an analysis of the identification of fluid types was carried out using the double apparent resistivity method with the results obtained that in Zones A and B there are 2 types of fluids, namely hydrocarbons and water with a depth limit of 3650 ft in Zone A and 4558 ft in Zone B. By knowing the type of fluid, the hydrocarbons contained in these two zones should be able to increase interest in the production of these zones as a potential zone for production, but it is necessary to perforate at a depth range indicated by the hydrocarbon fluid and carry out initial production tests to prove the results of the analysis in this study.
