Abstract

Central Java is one of the areas high and varied disaster intensity, including landslides. One of the areas prone to high intensity landslides in the Central Java region is Wonogiri, especially the Kismantoro area. This research aims to analyze the physical profile of soil in landslide-prone areas and analyze the dominant factors that influence landslide in Kismantoro District. The type of research that will be carried out is quantitative research by calculating the vulnerability and physical factors of landslide disasters dari primary data using regression equations. The sampling method used was Purposive Random by determining the number and sample points based on landslide events. The physical parameters tested include soil water content, soil texture, permeability, porosity, liquid limit, plastic limit, volumetric weight and specific gravity. The data analysis method used is mixed analysis which involves 3 analysis parameters, namely soil testing, GIS analysis and statistical analysis. The research results show that the soil physics of Kismantoro is dominated by a clay-sand texture. Permeability is in the range of 0.001-0.008 cm/day. Soil conditions are very bad with a range of 88% -97%. Low-medium soil plastic class with a value range of 0.1-0.10%. This research concludes that the plasticity of the Kismantoro soil has a significant role in the level of landslide susceptibility.
