Bedrock identification using resistivity method at campus II of Universitas Syiah Kuala, Banda Aceh

Abstract

Research of resistivity method at campus II Universitas Syiah Kuala has been conducted with the SuperSting 68 instrument. There were three lines, each 330 meters long with a spacing of 6 meters. The purpose of the research was to determine the depth of the bedrock at campus II of Universitas Syiah Kuala. The results showed that there was a conductive and resistive coating with a resistivity value of between 2–1250 Ωm. The rock types were composed of water-saturated rocks, Tuffs sandstone, and andesite. The supposed bedrock rock is an andesite rock with a resistivity of 170-1250 Ωm with good density. In conclusion, the separation between the sediment and the bedrock was visible at a depth of up 10 meters across the measuring track.
