Identifikasi Zona Akuifer Air Tanah Menggunakan Metode Geolistrik Resistivitas Konfigurasi Wenner dan Schlumberger di Megal Kabupaten Blora

− Geoelectric research has been carried out in Megal, Blora Regency with the Wenner and Schlumberger configuration resistivity geoelectric method. The purpose of this research is to provide information about the subsurface layer as a potential point for groundwater drilling which has variations in rock lithology. The geoelectric method works by utilizing the propagation of electric current located below the surface so that data is obtained which is processed using Res2dinv software with the inversion method, and interpreted to identify groundwater aquifer zones in Megal, Blora Regency. The results of the Wenner configuration show up to a depth of 17.2 meters but the data does not find groundwater sources. Meanwhile, the results of the Schlumberger configuration showed up to a depth of 31.5 meters and an anomaly was found so that drilling was carried out to obtain soil layer data.
