Abstract

Kecamatan Lumbir, Kabupaten Banyumas mempunyai sumber daya mineral non logam berupa lempung dan sumber daya batuan berupa andesit dan batupasir. Analisis sebaran, jenis, dan kualitas diperlukan untuk optimasi pemanfaatan sumber daya alam tersebut. Analisis laboratorium meliputi analisis XRD (X-Ray Diffractometry), XRF (X-ray Fluoroscence) dan analisis kuat tekan batuan. Analisis XRF menunjukan lempung di daerah Lumbir mempunyai unsur SiO2 yang tinggi (berkisar antara 39 – 54,5 %) sehingga dapat dijadikan bahan campuran dalam pembuatan semen, gerabah kasar, dan batu bata. Sumber daya batuan berupa andesit di Desa Canduk dan Desa Parung Kamal memiliki nilai Kuat Tekan Ultimit (qu) berkisar antara 247,7547 kg/cm2 - 45,4674 kg/cm2, sehingga dapat digunakan sebagai batu hias dan batupasir di Desa Karanggayam dapat dijadikan tanah urug

Abstract

The structure of Exia is composed of Miocene built-up carbonates formed by shear faults. The buildup carbonate feature in the Exia prospect can be seen from the high elevation surrounded by lows with an NNE-SSW and NE-SW trending. The MA-1, SE-1, MI-1 wells are several wells in the Tiaka and Senoro Fields which are proven to have large gas reserves. Tiaka Field is located to the west of the Exia Well, while Senoro Field is to the northeast. The study used primary data from the Exia-1 well in the form of cutting samples. The wet and dry cutting samples were further processed into thin section. This thin section is then carried out for petrographic, XRD, and SEM analysis. Tomori Formation starts from the deeper environment FZ1 upwards to the shallower FZ5 –FZ6 (reef) with open marine and restricted areas. The allochem that composes the limestone at The Matindok Formation consists of red algae fragments and benthic forams which indicate the facies zone of formation in FZ 4 (slope). In the upper Mantawa Formation, it is still quite clear the presence of large forams indicating a reef association environment (FZ5-FZ6), but the presence of a large number of planktonic forams indicates a deeper depositional environment / slope, so it is possible that large forams were transported from a shallower environment. The Kintom Formation have rock provenance ranging from continental blocks in the interior of the craton to a recycled orogeny section of recycled quartz zone.

Abstract

Pada RW 03 Kelurahan Jabungan, Kecamatan Banyumanik, Semarang terdapat sebanyak 169 Kepala Keluarga. Estimasi dengan asumsi setiap keluarga beranggotakan 4 orang, maka kebutuhan sehari-hari masyarakat RW 03 berkisaran 40.560-54.080 liter/hari. Warga RW 03 memperoleh air bersih dari tiga sumber, yaitu dari sumur gali, Sungai Jabungan dan mataair. Isu terkait air bersih di RW 03 dapat dikatakan terjadi pada saat musim kemarau. Salah satu dampaknya adalah debit sumur gali yang menurun drastis setiap musim kemarau. Alternatif sumber air terdekat selanjutnya adalah dari Sungai Jabungan. Akan tetapi, diperlukan treatment pengolahan terlebih dulu agar dapat memakai air dari sungai tersebut untuk keperluan MCK. Hal tersebut menyisakan pilihan terakhir pada sumber air dari mataair yang lokasinya jauh dari pemukiman, hingga saat ini kondisi pipa yang mengalirkan mataair ini ada banyak titik kebocoran dan hanya ditambal dengan sangat sederhana. Prioritas bagi warga RW 03 Kelurahan Jabungan, Kecamatan Banyumanik selaku mitra Pengabdian Kepada Masyarakat (PKM), adalah pemenuhan kebutuhan air bersih selama musim kemarau karena selain menjadi kebutuhan utama untuk hal domestik, di masa sekarang ini juga sangat diperlukan untuk tetap menjalankan protokol kesehatan untuk mencegah COVID-19. Menindaklanjuti kebutuhan tersebut, sebagai pelaksana PKM telah menyediakan fasilitas penyedia air bersih minimal untuk memenuhi kebutuhan warga RW 03.

Abstract

The Tarakan Basin is one of the basins that has been producing hydrocarbons since 1901, with nine active oil fields to this day. The exploration of oil and gas in the Tarakan Basin has been ongoing for a considerable amount of time and can be considered as the oldest exploration in Indonesia that continues due to its estimated economically viable reserves based on its geological conditions. Research on the evaluation of reservoir characteristics in the Tarakan Sub-Basin with a Pliocene age interval aims to determine the subsurface lithology and fluid conditions qualitatively and the quantitative characteristics of the reservoir rocks. This study utilizes quantitative petrophysical analysis using a deterministic method with primary data consisting of wireline log data, as well as secondary data including core data, mud logs, biostratigraphy data, drill stem test data, and sidewall core data. Based on the analysis results, the petrophysical properties of the target reservoir in the study area include an average shale volume (VSH) of 16.65% - 29.31%, average effective porosity (PHIE) of 11.80% - 27.09%, which falls into the categories of fair to excellent quality, hydrocarbon saturation ranging from 7.68% - 43.03%, an average permeability value (PERM) of 10.03 mD - 613.29 mD, falling into the categories of good to very good, and a net pay thickness ranging from 4 feet to 16.7 feet, with a total thickness of 67.4 feet containing oil and gas fluids.
