Pemetaan Batu Gamping di Lokasi Rencana Pembangunan Pabrik Semen, Khususnya di Daerah Lau Adimdayang Desa Sulkam Kecamatan Kutambaru Kabupaten Langkat dengan Metode Wenner-Schlumberger

Abstract

The study of Geology done in the area of Langkat Kutambaru Lau Adimdayang districts. This study aims to look at the structure of the subsurface limestone containing suspected based on the value of resistivity below the rock surface. To obtain resistivity values used geoelectric resistivity method Wenner- Schlumberger configuration with 32 electrodes and the distance between electrodes 5 m. This study was conducted on 17 points with the length of each track 155 meters, the apparent resistivity values were then treated with Software Res2Dinv as actual resistivity values. The results of the inversion of the apparent resistivity of the subsurface structure interpreted as that can be associated with a region containing the spread of limestone. From the results of the processing and the data obtained interpreted maximum depth of 30 m which consists of various rock types and the map were than treated with Surfer10.
