| Summary: | This research was conducted in Ijo watershed the Province of Yogyakarta
Special Region. The aim of the research is to study of landslide susceptibility, and
the influence of physical and human aspects to the landslide susceptibility in Ijo
watershed.
This research used landform, slope, rock wheatered, road buffer, river
buffer, landuse, and soil texture as parameters to produced landslide
susceptibility map of Ijo watershed. The weight of each parameter delivered using
AHP method.
This research was applying GIS to generate landslide susceptibility map of
Ijo watershed. To validate the model has been done by comparing landslide
susceptibility map with landslide density in each susceptibility class.
The result of mapping shows that 67,65% area of Ijo watershed is
classified as non susceptible and low susceptible zone. Moreover, 20,01% of total
study area is categorized as moderate susceptible to landslide. the rest area is
included in high and very high susceptible zone.
