Penelitian ini dilakukan untuk mengidentifikasi keberadaan akuifer dan potensi air tanah untuk ketersediaan cadangan air bersih di wilayah kecamatan sukahening, kabupaten tasikmalaya. penelitian dilakukan menggunakan metode geolistrik resistivitas konfigurasi schumberger pada 21 titik sounding yang tersebar di desa-desa pada daerah penelitian dengan instrumen ojs resistivity meter. pengolahan data lapangan menggunakan perangkat lunak ipi2win untuk mendapatkan nilai tahanan jenis aktual dan pemodelan 3d menggunakan software rockwork. hasil penelitian menunjukkan bahwa jenis perlapisan batuan yang terdapat pada daerah penelitian antara lain pasir tufaan, tufa, dan batuan breksi. lapisan pembawa air atau akuifer didominasi oleh pasir tufaan dengan jenis akuifer uncofined aquifer dan confined aquifer. penampang hasil penelitian menunjukkan persebaran zona akuifer mengalami perubahan terhadap topografi. kedalaman akuifer terletak bervariasi dari 2.00 meter hingga 96.90 meter dari permukaan tanah. ketebalan akuifer mencapai 30 meter dan berdasarkan persamaan darcy didapatkan volume akuifer sebesar 3.87 x 107 (38.729.787) m3. kata kunci : volume akuifer, geolistrik, schlumberger, ipi2win, rockwork, kabupaten tasikmalaya

The research is to identify the presence of aquifers and groundwater potential for the water reserve in the Sukahening Sub-district, Tasikmalaya Regency. The research was conducted using the geoelectric resistivity method Schumberger array with 21 sounding points in the research area with the OJS Resistivity meter instrument. The data were processed using IPI2Win software to get true resistivity values and 3D modeling using Rockwork software. The results shows layers of lithology in the research area were Tuffaceous sand, Tuff, and breccia. The aquifer layers which is dominated by Tuffaceous Sand while the type of the aquifers is dominated by Uncofined Aquifer and Confined Aquifer. The cross-section distribution of the aquifer zone has changes following by the topography of the area. The depth of the aquifer layers is varies from 2.00 to 96.90 meters from ground level. The thickness of the aquifer reaches 30 meters and based on the Darcy law the volume of the aquifer layers is 3.87 x 107 (38.729.787) m3.
