Integrated Of Surface And Subsurface Landslide Potential Analysis Using Refraction Seismic Method On Rubber Plantation Area, Imogiri District, Bantul, D. I. Yogyakarta
Bantul Regency has many points that become landslide potential areas, this is because Bantul Regency is consist of structural zone of Batur Agung, and it consist of weathered volcanic rocks. The research area is located at Rubber Plantation Imogiri Sub District that has landslide potential. The purpose of the research is identifying surface and subsurface condition for knowing landslide potential. The research methods are used refraction seismic acquisition with T-X counting CDM (Critical Distance Method) and Plus Minus method on 9 tracks with a distance of 2 meters offset. Through data processing using CDM method can know the existence of two layers with a slope reaching 68.019o while with Plus Minus method can know that in the first layer there is a sandstone lithology with wave velocity 1121,795 m / s while in the second layer there is lithology of clay with velocity wave 1248,647 m / s. It can be interpreted that the landslide plane is claystone. Keywords: Landslide Potential, CDM and Plus Minus, Refraction Seismic, Sandstone, Claystone
