Penentuan Litologi Batuan dan Muka Air Tanah dengan Metode Geolistrik Konfigurasi Wenner Schlumberger di Daerah Landfill Pltu Labuhan Angin Sibolga

Abstract

Water table and earth lithology identification at areal of landfill Labuhan Angin district, Sibolga. The method used in this study is Geo–electrical resistivity Wenner–Schlumberger Configuration With electrode spaced 5 meter bay taking the data of 9 tracks and each track is 155 metrers. The expacted penetration depth reaches 28,7 meters. Data procesing using non – linear least square optimazition with that of 2D inversion software RES2Dinv. From analysis of 9 track shows that landfill of PLTU consist top soil, sand saturated water, sandstone, sand clay. The water table is at depth amount 0,4 – 2 meters.
