- Determination of the sliding plane of landslides research has been studied at RT. 22 RW. 09 Tulungrejo, Ngantang, Malang at coordinates 7° 49 17" south latitude, 112° 23 38" east longitude, with a height of 800 meters above sea level. Resistivity geoelectric method with dipole-dipole configuration is a geophysical method that can be used to analyze the sliding plane with lanslides potential. This geophysical method was aimed to predict subsurface structure and landslides sliding plane. Data acquisition was done as much as 4 tracks. The data processing of the measurement results performed using Res2Dinv software. Based on the result of subsurface cross section, the area was thought to have subsurface rock lithology with resistivity value between 3.22 Ω.m - 856 Ω.m. At the resistivity values between 3.22 Ω.m - 78.2 Ω.m indicated as a layer of clay and sandy clay stone, while the resistivity values between 78.2 Ω.m - 856 Ω.m as saturated gravel and gravel. Track sliding plane 1 was at a depth of 6 m - 8.5 m with a slope of track 25.040. Track sliding plane 2 was at a depth of 6 m - 8.5 m with a slope of track 260. Track sliding plane 3 is at a depth of 6 m - 8 m with a slope of track 5.680. Track sliding plane 4 was at a depth of 6 m - 8.5 m with a slope of track 30.170.
