【 摘 要 】

Landslide is a general term that covers a wide variety of soil forms and processes involving earth, rock, or debris movements falling on the lower slopes below due to the influence of gravity. This disaster occurs in many parts of Indonesia, including in Bantul Regency due to its relatively unstable land and vulnerability to land movement. In addition, a landslide disaster can lead to casualties and considerable material losses. This study aims to build an Android-based GIS application that can map landslide-vulnerable areas by dividing the vulnerability into three categories, namely low, medium, and high, using the Analytical Hierarchy Process (AHP) method. This research is expected to be useful for the community and the Government in order to be alert and responsive to handle landslide disasters in areas that have been declared vulnerable to landslide disasters. The results of research by using the GIS application produced showed that from 17 districts in Bantul Regency, 6 are districts that have a high vulnerability level of landslide disasters. The six districts are Pleret, Imogiri, Kretek, Sanden, Srandakan, and Bambanglipuro.
