Abstract

Dengkol Village, Malang Regency, East Java, is an area that is known to be difficult to get water sources or is a red zone for well drillers, because there are several excavation points that fail to get water. The depth of the existing well is close to 100m, dominated by hard rock, so drilling costs in this area are quite expensive. This research aims to determine the depth of the aquifer layer at the research location, so that it can be used as a reference in drilling wells at that location. This research was carried out using the geoelectric VES method with a schlumberger configuration and an electrode path length of 400 meters. The research results show that the subsurface lithology in Dengkol Village consists of clay rock, alluvium, tuff breccia at a depth of 0,7-4,24 m with rock resistivity value of 6892 Ωm and a depth of 30.5 – 46,3 m with a rock resistivity value of 521 Ωm, is a layer of hard rock. Sandstone rock at a depth of 46,3 – 167 m with a rock resistivity value of 3,95 Ωm is an aquifer layer.
