Model Resistivitas Lapisan Bawah Tanah Di Perumnas Griya Bina Widya Unri Dengan Menggunakan Metode Geolistrik Konfigurasi Elektroda Schlumberger
The research has been conducted about resistivity underground modeling located at Perumnas Griya Bina Widya UNRI Tampan Subdistrict of Pekanbaru City. Resistivity underground data taken using Schlumberger geoelectrical method of electrode configuration. Geoelectric data processed with Vertical Electrical Sounding (VES). Based on the research, there were four layers in each block with different level of resistivity. The number of resistivity in the first layer ranges between 97.3 Ωm to 389.8 Ωm. The number of resistivity in the second layer ranges between 72.0 Ωm to 1556.2 Ωm. The number of resistivity in the third layer ranges between 19.3 Ωm to 661.9 Ωm. The number of resistivity in the fourth layer ranges between 98.0 Ωm to 605.2 Ωm. The smallest number of resistivity was found in block G with 19.3 Ωm and the thickness was 2.5 m which was interpreted as the layer of clay, while the biggest number of resistivity was found in block B with 1556.2 Ωm and the thickness was 19.5 m which was interpreted as the layer of dry gravel.
