PENGGUNAAN METODE GEOLISTRIK RESISTIVITAS KONFIGURASI SCHLUMBERGER UNTUK MENGETAHUI LAPISAN STRUKTUR LITOLOGI BAWAH TANAH DI TAMAN ILMU UNIVERSITAS RIAU

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.
