“…Metode ini dipilih karena air tanah umumnya bersifat konduktif dan mempunyai nilai resistivitas yang lebih kecil. Sedangkan penggunaan konfigurasi Schlumberger diharapkan mampu mengidentifikasi sebaran resistivitas secara sounding, sehingga dapat menduga keberadaan akuifer air tanah (Muhardi, Perdhana, and Nasharuddin 2020). Nilai resitivitas batuan/material tidak selalu sama.…”

This research is motivated by development and population growth continues to increase from day to day. The impact of population growth is the increase in residential land. The increase in residential land is sometimes not accompanied by the provision of clean water by PDAM, so that people use dug wells or drilled wells. In the Kolaka area, especially the Kolaka District area, which is the research location, it is also a location that is difficult to find fresh water, so the geoelectric method plays a very important role in efforts to determine which locations contain fresh water. This research uses resistivity geoelectric method with Wenner and Schlumberger configuration. Processing data using Res2Dinv to map 2D isoresistivity. The well depth data was processed using Microsoft Excel, Surfer 10.2 application and ArcGIS to create a groundwater network map. The measurement trajectory uses a space of 7 meters, 20 meters and 40 meters. The results of the study obtained different resistivity values for each rock. The resistivity variation obtained starts from 0.453 – 13,988 m. Groundwater resistivity values are in the range of resistivity values of 0.453 – 33.3 m. The lithology of the aquifers in the study area is alluvial and sandstone. In the research location, groundwater is generally found at a depth of more than 5 meters

“…Akuifer umumnya mengandung air tanah dan mempunyai kemampuan untuk mengalirkan air tersebut secara alami (Darsono, 2016). Akuifer bebas yang mengandung air tanah dangkal biasanya dapat ditemukan pada kedalaman kurang dari 40 m (Muhardi, Perdhana and Nasharuddin, 2019).…”

telah diidentifikasi menggunakan metode geolistrik resistivitas. Pengambilan data dilakukan menggunakan alat geolistrik Automatic Resistivity System (ARES) 12 V. Pengukuran di lapangan mengaplikasikan konfigurasi dipol-dipol dengan panjang lintasan 195 m dan jarak antar elektroda 5 m. Hasil pengukuran menunjukkan sebaran resistivitas bawah permukaan hingga kedalaman 40,9 m, dengan nilai 5 Ωm -908 Ωm. Hasil interpretasi menunjukkan bahwa lapisan yang mempunyai nilai resistivitas sebesar 5 Ωm -10,5 Ωm merupakan lapisan akuifer dengan litologi berupa pasir. Lapisan ini diduga sebagai akuifer dangkal (akuifer bebas), karena berada pada kedalaman ± 6 m -31,2 m.

Lack of clean water when entering the dry season is a problem that often occurs in the FMIPA University of Jember. The purpose of this research is to know and estimate the potential distribution of the aquifer in the research area. 3D modeling of resistivity data was carried out using Voxler software. The input of resistivity data from the measurement results in the research area that the inversion process had carried out. The modeling results obtained an aquifer potency of 207.862,21 m3 or 21.63% of the total volume on the model image's cross-sectional map, with an irregular distribution pattern. Finally, using this method, the modeling of the aquifer potential volume and distribution can be estimated, and can be used as consideration in the use of groundwater in the Faculty of Mathematics and Natural Sciences, University of Jember.
