MODEL RESISTIVITAS LAPISAN BAWAH TANAH DI PERUMNAS GRIYABINA WIDYA UNRI DENGAN MENGGUNAKAN METODE GEOLISTRIK KONFIGURASI ELEKTRODA SCHLUMBERGER
Abstract: The research has
been conducted about resistivity underground modeling located at PerumnasGriya
Bina Widya UNRI Tampan Subdistrict of Pekanbaru City. Resistivity underground
Datataken using Schlumberger geoelectrical method of electrode configuration.
Geoelectric dataprocessed with Vertical Electrical Sounding (VES). Based on the
research, there were four layers ineach block with different level of
resistivity. The number of resistivity in the first layer rangesbetween 97.3 Ωm
to 389.8 Ωm. The number of resistivity of the second layer ranges between
72.0Ωm to 1556.2 Ωm. The number of resistivity in the third layer ranges
between 19.3 Ωm to 661.9Ωm. The number of resistivity in the fourth layer
ranges between 98.0 Ωm to 605.2 Ωm. Thesmallest number of resistivity was found
in block G with 19.3 Ωm and the thickness was 2.5 mwhich was interpreted as the
layer of clay, while the biggest number of resistivity was found inblock B with
1556.2 Ωm and the thickness was 19.5 m which was interpreted as the layer of drygravel.
