【 摘 要 】

The objective of this research was to detect groundwater, to provide information of subsurface structures, and to deterMine the thickness of each layer. Geoelectric method used is the resistivity method. Where the subsurface material resistivity data is obtained by injecting an electric current from the earth's surface below the surface, its current and potential are measured on the earth's surface. The data recording technique used sounding method (1D), which we measure data below the measurement point. The electrode configuration was a Wenner configuration in which the distance of the electrode at the ground surface has the same distance. With a laboratory test unit using a container made of glass 100×10×40 cm3 which contains clay, sand, and water. Due to the complexity of subsurface materials, IPI2Win as data processing software resistivity. From data processing, it can be seen that there were three layers of subsurface material with successive thicknesses of clay (4 cm), sand (12 cm), and water (8 cm). It can be concluded that the tool is able to detect the number of subsurface layers and the thickness of each layer. It could also deterMine the difference of the type resistivity of each layer type detected.
