Abstract

Banyumas highly vulnerable to landslides. These conditions require research
onlandslide risk levels. Geographical information about the landslides risk is very
important to reduce the disaster vulnerability level. Spatial presentation of
disaster will be very useful to society because it can be used to identify disasterprone
areas. Pekuncen subdistricts in Banyumas have relief with a height
between 500 meters to 1200 meters above sea level. Slope is dominated by
medium to steep (8% - 25%). The highest rainfall average is 221 mm, with an
annual rainfall of 2,648 mm height and number of rainy days 266 days. Based on
these data it appears that the region is prone to landslides. The method used is
descriptive quantitative analysis with spatial analysis using ArcGIS to analyze
physical and social parameters so that the result of the landslides level of danger
and landslide risk level can be used as reference in disaster mitigation efforts in
the district of Pekuncen, Banyumas Regency.
