Susceptibility Zoning of Soil Movement in Tawangmangu District, Karanganyar Regency with Bivariate Statistic Method - Weight of Evidence

Tawangmangu district which is located in Karanganyar Regency, Central Java a crowded area susceptible to disaster. Therefore, susceptibility zoning analysis needed support the planning and development of area. The method used bivariate statistics - weight evidence has never been implemented its location. There are two types data, data potential soil movement case (divided into train as 61 points test 40 points); parameter causes. Parameter processed be WoE (Weight Evidence) map through use know weight. Later on, it will validated based on AUC value. If it’s > 0,60, then process proceed. value 0,60 type lithology, slope, hill, elevation, slope direction, distance from fault, index vegetation density. All those parameters attached being final by data. Further, zonation consists four; zone very low susceptibility, low, medium, high. 19,68%. Zone mostly 24,57%. medium 25,88%. Meanwhile, high 29,86%. result validation shows that model made belongs good category, 0,757.
