Abstract:
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.
