| Summary: | Landslides cause significant economic, physical, and environmental losses.
This research aims to analyse landslide risk using hazard analysis,
vulnerability analysis, regional capacity analysis, and landslide disaster
risk analysis. The study was conducted in South OKU Regency, one of the
regencies in South Sumatra Province, which frequently experiences
landslides. The method used in this research is a survey method. The data
includes DEM data, slope types, land cover type maps, rainfall maps, soil
type maps, physical infrastructure, economic losses, environmental damage,
development plans, regional capacity index, and data from structured
interviews with 19 sub-district heads. Landslide analysis uses the weighting
and overlay method; vulnerability analysis uses Multi-Criteria Decision
Analysis; capacity analysis refers to the Hyogo Framework for Actions; and
risk analysis is based on Perka BNPB No. 2 of 2012. The results of the
analysis show that the landslide hazard in South OKU Regency is high and
spread across more than half of the sub-districts. This landslide hazard is
very vulnerable to the condition of vital physical infrastructure, has the
potential to cause significant economic losses, and can damage
environmental conditions. On the other hand, regional capacity in dealing
with landslide danger is categorized as moderate. The risk of landslides in
South OKU Regency is in the medium disaster risk class. Therefore, it is
necessary to strengthen community capacity and increase preparedness in
facing landslide disasters to minimize the risks posed. |
