Analisis Potensi Longsorlahan di Kecamatan Kerjo Kabupaten Karanganyar Provinsi Jawa Tengah

Landslides occur due to the process of transferring land in an area that takes place in a large amount in a short time. Landslide potential analysis aims to: (1) map the level of landslide potential and (2) analyze the landslide trigger factors in the study area. Every potential landslide disaster itself is aggravated by the rate of population growth and the behavior of the human hand itself. The increasing rate of growth and inappropriate land use causes concrete evidence of land use vulnerability and the ability of land to escape water. Related landslide parameters are: (1) slope, (2) soil type, (3) soil depth, (4) groundwater level, (5) rainfall intensity and (6) rock type. The method used is the survey method and the method of sampling uses a stratified purposive sampling. Based on the results of the study, the distribution of potential landslide prone areas and moderate landslide hazard levels in the study area consisted of a total classification classification of (5-12) on landunits: KIIV12M, PIIV13M, PIV12G, PIV12M, SIIV12M, SIV12M dan SIV13M. There are in the villages of Plosorejo, Karangrejo, Gempolan and Ganten. While the severe landslide hazard level in the study area consisted of a total classification of (13-20) rating on landunits: BIVV12M, KIIIV12M, KIVV12M, PIIIV12M, PIIV12M, PIVV12M, SIIIV12M, SIVV12M dan TLIVV12M. There are in the villages of Plosorejo, Karangrejo, Gempolan, Ganten and Kwadunga
