Abstract

Landslides are one of the most common disasters in Indonesia, Bawang sub-district is prone to landslides because it is located at the foot of the Prau Mountains which has a slope from flat to very steep. The objectives of this research are 1) To analyze the landslide potential in Bawang sub-district of Batang Regency, 2) Validate landslide potential with actual landslide occurrence in Bawang subdistrict, Batang regency, 3) Analyze dominant factors causing landslide in Bawang subdistrict, Batang regency. The sampling method in this research is purposive sampling. Data analysis method of this research uses scoring, overlay, and frequency table. This research uses 3 parameters including land unit parameters consisting of geological parameters, slope, and soil type, rainfall parameters, and land use parameters. The results of this research are 1) the potential level of landslide vulnerability which is divided into 3 classes: low, medium, and high. Low vulnerability is found in 13 land units namely Al-L1-Medlit, Al-L3-Medlit, GJ-L1-An, GJ-L1-Medlit, GJ-L1-Medreg, GJ-L2-An, GJ-L2-Medlit, GJ-L2-Medreg, GJ-L3-An, GJ-L3-Medlit, GJ-L4-Medlit, Kal-L1-Medlit, Kal-L2-Medlit. There are 13 land units with medium vulnerability, namely Al-L1-Medlit, Al-L2-Medlit, Al-L3-Medlit, Al-L4-Medlit, Al-L5-Medlit, GD-L1-An, GD-L2-An, GD-L3-An, GD-L4-An, GJ-L1-An, GJ-L1-Medlit, GJ-L1-Medreg, GJ-L2-An. And high vulnerability there are 17 land units namely Al-L5-Medlit, GD-L4-An, GD-L5-An, GJ-L3-An, GJ-L4-An, GJ-L4-Medlit, GJ-L4-Medreg, GJ-L5-An, GJ-L5-Medlit, GJ-L5-Medreg, Kal-L4-Medlit, Kal-L5-Medlit, GD-L5-An, GJ-L4-An, GJ-L5-An, GJ-L5-Medlit, Kal-L5-Medlit. 2) There is a suitability between landslide points and potential landslide vulnerability with 80% suitability percentage. 3) The dominant factors causing landslides are slope and rainfall with a percentage of 29%.
