Abstract

Penyebaran air tanah yang tidak merata dipengaruhi oleh faktor-faktor jenis batuan, bentuk topografi permukaan, jenis vegetasi dan jumlah curah hujan suatu tempat. Eksplorasi geofisika metode geolistrik tahanan jenis konfigurasi dipol-dipol digunakan untuk mengidentifikasi sebaran akuifer air tanah di desa Sea  Kabupaten Minahasa. Data diolah menggunakan software Res2Dinv dan menghasilkan peta model resistivitas bawah permukaan 2 dimensi yang menggambarkan keadaan lapisan tanah. Teridentifikasi sebaran akuifer air tanah permukaan dengan kedalaman ≤ 20 m di sepanjang lintasan pengukuran. Akuifer air tanah dalam diidentifikasi pada lintasan 1 dengan kedalaman sampai 30 m dan 60 m.  Akuifer air tanah dengan kedalaman< 60 m mempunyai potensi dijadikan sebagai sumber air tanahThe uneven distribution of ground water is influenced by factors such as rock type, surface topography, vegetation type and the amount of rainfall in a place. Geophysical exploration of the dipole-dipole configuration type of geoelectric resistivity method is used to identify the distribution of groundwater aquifers in Sea village, Minahasa District. The data is processed using Res2Dinv software and produces a 2-dimensional subsurface resistivity model map that describes the state of the soil layer. Distribution of surface ground aquifer with a depth of ≤ 20 m along the measurement line was identified. Deepwater aquifers were identified in l1ne 1 with depths up to 30 m and 60 m. Groundwater aquifers with a depth of <60 m have the potential to be used as ground water sources
