Abstract
Research has been carried out at the Science Park, Riau University to determine the layers of underground lithological structures using the one-dimensional Schlumberger configuration Geoelectric resistivity method. Research data processing is done using Software Progress. The results of data processing show that lanes 1 and 2 consists of layers of alluvium, sand, gravel, and clay. On track 1, the highest soil layer resistivity value of 863.14 m is interpreted as a layer of sand and gravel at a depth of 2.28 - 31.12 m, while the smallest is 226.90 m which can be interpreted as a layer of clay at a depth of 0.68 - 1.28 m. On track 2, the highest soil layer resistivity value of 1027.83 m is interpreted as a layer of sand and gravel at a depth of 0.28 - 1.15 m, while the smallest is 188.08 m interpreted as a clay layer at a depth of 0 - 0.28 m. The highest and lowest resistivity values tend to be identified as sand, gravel, and clay, respectively.
