    Groundwater is one of the best water resources for clean water, which can be used to meet the needs of people's lives, such as household, irrigation, and industrial needs. Based on the theory that changes in land use will have an impact on groundwater absorption. This study aims to see and analyze underground water absorption around the gate of the University of Riau using the geoelectric method of the Schlumberger configuration. Based on the results of measurements of resistivity values and groundwater infiltration in the Gate area of Riau University, Simpang Baru, Tampan, Pekanbaru, Riau, it is interpreted for the soil layer obtained with resistivity values ranging from 235.38 to 595.66 ohm meters with a depth of obtained up to 35 meters, and for the interpretation of lithological layers, namely clay, distribution of gravel, sandstone, and sand and gravel. The underground water infiltration value obtained from the calculation results is that for the clay layer is 13.42 m/year, the gravel distribution layer is 13.42 m/year, the sandstone layer is 40.27 m/year and the sand and gravel layer is 40.27 m/year.
