Identifikasi Bidang Gelincir Pemicu Bencana
Tanah Longsor Dengan Metode Resistivitas 2
Dimensi Di Desa Pablengan Kecamatan Matesih
Kabupaten Karanganyar
Investigation of landslide slip surface has been conducted at Salaman Sub village,
Pablengan Village, Matesih District, Karanganyar Regency, Central Java Province by using
dipole-dipole array geoelectrical resistivity method. Data processing were using Res2Dinv
version 3.45 (semi demo version) software. The interpretation result showed that at the
research area was found lithology consist i.e. clay, wet clay, sandy clay until claysand, sand
until breccia. The slip surface is a wet clay layer with resistivity value range from 19.3 Ω m
to 36.6 Ω m, for one section was found with depth of 1.7 meter until 17 meters, and for two
section was found with depth of 8.9 until 16.4 meters.
