    ANALISIS SEBARAN AIR BAWAH TANAH SECARA HORIZONTAL MENGGUNAKAN METODE GEOLISTRIK KONFIGURASI WENNER DI KELURAHAN SIMPANG BARU
    (Elfitra, 2023-06) Manurung, Nova Yuliana Br; Juandi, Juandi
    subsurface lithology, especially rocks containing groundwater using the geoelectric method have been investigated. The geoelectric method is a geophysical method used to determine the geological conditions of the subsurface of the earth based on variations in the resistivity values of the rock types. The method used in this study is the Wenner configuration geoelectric method. This method has several advantages, such as good vertical resolution and high sensitivity to lateral changes. Apart from knowing about the distribution and depth of subsurface water, and subsurface conditions, data from research results in the Simpang Baru Village area can be used regarding the need for clean water for the community. Data obtained from measurements using the Wenner configuration geoelectrical method are processed to obtain resistivity, while for interpretation uses the software Res2Dinv. On a track with a length of 100 meters, it has a depth of up to 9.56 meters below the surface with a resistivity value with a lowest one of 0.370 Ωm and the highest one is 33141 Ωm. The points of water distribution at depths of 2.25 – 5.56 m have resistivity values of 0.37 – 1.89 Ωm corresponding to the horizontal line at points 30 – 84 m.
