PENENTUAN POTENSI AIR TANAH DENGAN METODE GEOLISTRIK KONFIGURASI SCHLUMBERGER DI JALAN LABERSA KELURAHAN SIMPANG TIGA KOTA PEKANBARU

Abstract

The determination of groundwater potential has been done on the labersa road of Simpang Tiga Village, Bukit Raya District, Pekanbaru City, Riau Province. using the Geoelectric Method Schlumberger Configuration. This research was aimed to interpret the subsurface lithology based on resistivity values of rocks in the research area. The number of trajectories were two points with a stretch of 150 m. Geoelectric data processing was done using Microsoft Excel and Progress Software. The resistivity values in the trajectories 1 range from 83,29 – 2513,42 ohmmeters. The lithology of trajectories 1 consists of sand, sandstone, and dry gravel. The resistivity values in the trajectories 2 range from 132,25 – 242,0 ohm-meters. The lithology of trajectories 2 consists of flakes, sandstone, gravel and groundwater. The potential of groundwater in the research area is 477,36 x 106 cubic meters
