This research is titled "Mapping the Potential of Groundwater Using the Schlumberger Configuration Geoelectric Method in Jati Mandiri Housing, Air Putih Village, Tuah Madani District, Pekanbaru City". The main objective of this study is to evaluate the groundwater resource potential in the area, where most residents still rely on boreholes and dug wells as sources of clean water. The geoelectric method with Schlumberger configuration was used to map the subsurface stratigraphy and resistivity characteristics, resulting in data with low measurement errors (2.61% and 3.41%). The measurement results indicate the presence of ten layers with resistivity variations ranging from 7.8 Ωm to 11.426 Ωm. The shallow layer (0.9 m - 3.13 m) is likely to be a shallow aquifer consisting of wet clay and sand material, while deeper layers indicate the presence of solid rock with water-filled voids. Further analysis shows that the main aquifer zone is located at a depth of 1.36-3.13 m, and the bedrock serves as an impermeable boundary that limits the groundwater flow system. This study is expected to provide valuable information for water resource management in the region.
