Geoelectric 2-D Wenner and 1-D Schlumberger configuration methods have been used for the research. Resistivity measurement of was conducted at the location using resistivitymeter of Naniura type NRD 22 S. Data of this research was processed using software Resistivity 2-D Inversion (Res2Dinv) for 2-D Wenner and software Vertical Electrical Sounding (VES) for 1-D Schlumberger. The results yields lithology data that consists of four layer formations. Both methods shows the same results. Therefore, both methods can be used to determine lithology and aquifer layer of a location.otherGeoelectricWennerSchlumbergerlithologyaquiferOther
