Abstract

This geological structure estimation is done by flowing an electric current under the surface, then analyzing the different electrical resistance depending on the rock's quality, the degree of density, and soil moisture conditions. The research location is in East Kabaena, Bombana Regency, Southeast Sulawesi Province. The type of tool used is the G-Sound, a cheap and reliable resistivity (geoelectric) measurement tool. The geoelectric method used in this exploration is the resistivity method with the Schlumberger Method electrode configuration. Then the interpretation of the geoelectric survey data using the IP2Win software represents a sounding point. The results of field investigations found that the limonite layer with groundwater content had a resistivity value range of 0.28 -20.00 ohm-m. Then the limonite layer with a few chunks of rock with a resistivity value of 50.00 - 150 ohm-meters. The saprolite layer contains groundwater with a resistivity value of 100-200 ohm-m. The bedrock layer with a resistivity value greater than 5.034.00 - 23.351.00 ohm-m is the lowest part of the laterite profile. The nickel laterite is in the limonite and laterite layers with a resistivity value of 50.00 - 150 ohm-m with an estimated layer depth between 3 - 50 meters. The thickness of the layer ranges from 8 - 15 meters. Boring tests must accompany the use of geoelectric tools for the identification of soil structures. Interpretation of geoelectric data on metallic mineral resources includes the interpretation of geoelectric data into geological conditions.
