Abstract

Abstract: The study was done at Semarang, Central Java. The purpose of this study is to determine the variation of field susceptibility to landslide in the city of southern Semarang. Vulnerability includes physical, social, economic, and environmental ones. Each region has varying levels, types and characteristics of vulnerability. The results show that the vulnerability level of landslide is divided into 4 parts according to vulnerability indicator in Perka BNPB number 2 of 2012. The index categories were also modified into five categories from very low (1, 00 to 1, 40), low (1, 41 to 1, 80), moderate (1, 81-2, 20), high (2, 21-2, 40) and very high (2, 41-3, 0). Southern Semarang has moderate and high degree of vulnerability. The average vulnerability rate is in the high category with an index value of 2, 20. The lowest average vulnerability is owned by Gunung Pati sub-District, while the highest vulnerability is owned by Candisari sub-District.
