Abstract
Daerah Desa Bocek yang terletak di Kecamatan Karang Ploso Kabupaten Malang merupakan daerah kekeringan pada saat musim kemarau, maka dari itu masalah yang di alami oleh penduduk di daerah penelitian yaitu memiliki keterbatasan air dan sulit untuk memenuhi semua kebutuhan sehari-hari karena kebutuhan penduduk yang tinggi apalagi di waktu musim kemarau. Maka dari itu masalah yang di alami oleh penduduk. Dari permasalahan yang di alami oleh penduduk maka dilakukan pengukuran geolistrik bertujuan untuk mengetahui kedalaman, ketebalan serta persebaran akuifer air. Agar bisa mengetahui keberadaan air tanah tersebut yang tersimpan dalam suatu wadah (akuifer) yaitu merupakan formasi geologi yang jenuh air dan yang mempunyai kemampuan untuk menyimpan dan meloloskan air dalam jumlah yang cukup dan ekonomis. Metode geolistrik merupakan salah satu metode geofisika untuk mengetahui perubahan tahanan jenis lapisan batuan di bahwa permukaan tanah dengan cara mengalirkan arus listrik DC (Direct Current) yang mempunyai tegangan tinggi ke dalam tanah. Maka metode yang digunakan yaitu metode Geolistrik Resistivtas konfigurasi Schlumberger karena metode tersebut sangat cocok untuk mencari keberadaan akuifer air tanah bahwa permukaan. Dari permasalahan yang di alami oleh penduduk maka dilakukan pengukuran geolistrik bertujuan untuk mengetahui kedalaman, ketebalan serta persebaran akuifer air. Pada penelitian ini, pemodelan 1 Dimensi nilai resistivitas atau hasil Inversi mengunakan Software Progress. Maka dilakukan pengolahan data menggunakan Software Rockworks 16 diperoleh citra 2 Dimensi dan 3 Dimensi yang menejudkan pengambaran penampang pada setiap lapisan litologi dengan masing-masing kedalaman dan ketebalannya. Hasil pengolahan dan interpretasi yang didapatkan pada beberapa titik lapisan litologi yang memiliki Potensi Air Tanah yaitu pada lapisan Pasir Tufan (Akuifer Air) dengan kedalaman rata-rata dibahwa 150 meter. Lapisan Akuifer Air Tanah berada pada beberapa Lintasan yaitu GL1, GL2, GL3, GL4, GL5, GL6, GL7, GL8, GL9, GL10, dan GL11. Dengan rentang nilai resis akuifernya mulai dari 150 meter sampai 300 meter.

The Bocek Village area which is located in Karang Ploso District, Malang Regency is a drought area during the dry season, therefore the problem experienced by residents in the research area is that they have limited water and it is difficult to meet all their daily needs because of the high needs of the population. in the dry season. Hence the problems experienced by the residents. From the problems experienced by residents, geoelectric measurements were carried out aimed at knowing the depth, thickness and distribution of the water aquifer. In order to know the existence of the groundwater stored in a container (aquifer) which is a geological formation that is saturated with water and which has the ability to store and release water in sufficient and economical quantities. The geoelectric method is one of the geophysical methods to determine changes in the resistivity of rock layers below the ground surface by flowing DC (Direct Current) electric current which has a high voltage into the ground. So the method used is the Geoelectrical Resistivity method of the Schlumberger configuration because this method is very suitable for finding the presence of groundwater aquifers that the surface. From the problems experienced by residents, geoelectric measurements were carried out aimed at knowing the depth, thickness and distribution of the water aquifer. In this study, 1 Dimensional modeling of resistivity values or inversion results uses Software Progress. Then the data processing using Rockworks 16 software obtained 2 Dimensional and 3 Dimensional images which resulted in the depiction of the cross-section of each lithological layer with each depth and thickness. The results of processing and interpretation are obtained at several points of the lithological layer that have groundwater potential, namely the Tufan Sand layer (Water Aquifer) with an average depth of 150 meters. The groundwater aquifer layer is located on several trajectories, namely GL1, GL2, GL3, GL4, GL5, GL6, GL7, GL8, GL9, GL10, and GL11. With a range of aquifer resistance values ranging from 150 meters to 300 meters.
