Analisis Geologi Bawah Permukaan Untuk Identifikasi Akuifer Menggunakan Metode Resistivitas 2 Dimensi Di Daerah Desa Pulau Sarak Bagian Selatan, Kecamatan Kampar, Kabupaten Kampar, Provinsi Riau

This research area is located in the southern part of Sarak Island Village, Kampar District, Kampar Regency, Riau Province . So this research aims to determine the distribution of resistivity values of the subsurface layers of the research area and resistivity valuesof the subsurface layers that containing groundwater along with its depth, so that it can make it easier for local people to get ground water that can be used for their daily needs. Research on the identification of groundwater aquifer zones was carried out using the resistivity geoelectric wenner configuration method as primary data and well logging data as supporting data. From data acquisition, analysis and interpretation, there are 3 dominant layers found in the research area, that is clay with resistivity value range from 0.0883 – 2.25 Ωm, silt with resistivity values ranging from 2.44 – 18.4 Ωm, and sand suspected to be aquifers containing groundwater with thickness around 16 to 24 meters below the surface.with a resistivity value ranging from 12.9 - 88.5 Ωm, the resistivity value is the correlation between path 1 and path 2
