Abstract
Increasing challenges in securing sustainable water sources necessitate the exploration of aquifer potential and groundwater distribution patterns in Langsa City, specifically in Birem Buntung, Lengkong, and Meurandeh. This study integrates Self Potential (SP) and Vertical Electrical Sounding (VES) geophysical methods, supported by geological base maps and Digital Elevation Models (DEM), to validate the presence of groundwater and map its distribution. By combining SP and VES techniques, the research aims to provide a comprehensive understanding of subsurface hydrogeological conditions and aquifer potential. The integration of geophysical data with geological information and satellite imagery enhances the accuracy of groundwater identification and distribution analysis. A two dimensional (2D) modeling approach is employed to detail the spatial variation of subsurface features, offering a thorough evaluation of the groundwater potential of the area. The results of this research are expected to support more effective water resource management and policy development, aiding in the identification of viable aquifers that could serve as alternative clean water sources. These findings have broader implications for improving water security and contributing to more sustainable and resilient water systems in Langsa City.
