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. Keywords : Landslide Susceptibility, AHP, GIS, Ijo watershed
