MENENTUKAN STRUKTUR LITOLOGI BAWAH PERMUKAAN BUMI DI KELURAHAN SIMPANG BARU KECAMATAN TAMPAN PEKANBARU MENGGUNAKAN METODE GEOLISTRIK DENGAN KONFIGURASI ELEKTRODA WENNER

Abstract

Research has been done to determine the structure of lithology subsurface at Simpang Baru Kecamatan Tampan Pekanbaru by using geoelectric method in Wenner electrode configuration. The research measurement of current and voltage obtained by using geoelectric equipment. Then, this data was processed by excell to acquire the apparent resistivity. Res2Dinv is used to get the real resistivity and, to describe the subsurface lithology. According to the research results, the lithology of rock for both South-to-North measurement in Setia Mulia housing and West-to-East measurement in Ataiya housing were acquired in 7 lithological types , there are sandy soil, dry gravel, sand stones, sand, Alluvium, gravel and argillaceous sandstone.
