Abstract
Abstract Research was conducted to determine the groundwater aquifer layer in Manyarejo Village, Gresik Regency using the Schlumberger configuration 1D geoelectric method. This method is carried out by injecting an electric current into the earth through two electrodes and their potential current. If an electric current is injected into a medium and the potential voltage difference is measured, the resistance value of the medium can be estimated. This research was carried out at 8 points with a track length of 300-700 meters. Then measure with a resistivity meter. Then the data obtained is processed with the IP2Win application to create a picture of the subsurface structure. After interpretation, the results showed that the aquifer consists of 3 layers consisting of clay, clay sand, sand with clay and gravel. And groundwater in aquifer 1 is directed to the West (GL-8), while aquifer 2 is directed to the West and is directed to the North (GL-6). Aquifer 3. Groundwater is found in the resistivity value range of 1 to 100 Ohm Meters. In general, groundwater in aquifer 1 has a resistivity value 1 to 10 Ohm meters, while in aquifer 2 it has a resistivity value of 5 to 20 Ohm meters.
