Application of Vertical Electrical Sounding (VES) Method with Resistivity Meter Based on Boost Converter to Estimate the Potential of Groundwater Aquifers in Karang Anyar of Tarakan City

Abstract

Water catchment research has been done in Karang Anyar of Tarakan City with the aim to estimate the potential of groundwater aquifers. Groundwater is more widely used to meet the needs because of its better quality compared to surface water. The groundwater distribution is not only described vertically, to find horizontally can be seen through the deployment of geological formations that act as aquifers. Vertical Electrical Sounding method is one method that can be used to predict geological and hydrogeological conditions. Based on geoelectric exploration using a resistivity meter based on boost converter shows the presence of groundwater in a depth of 7. 91-_44. 33 meters with resistance of 27. 22 Ωm and the estimated lithology is sand. According the research could determine that resources ground water in Karang Anyar village is prospectly.
