Historically, the city of Semarang in Central Java Province, Indonesia has often experienced landslides due to a number of factors. This study aims to develop a landslide risk map and analysis of disperse level in that city to support risk reduction efforts. This research is an observational type whose data is analyzed quantitatively. Population is the physical condition of the community and those who have experienced landslides or those who live in disaster-prone areas. The variables of this study are the danger, vulnerability and capacity of the community in the face of landslides. Data analysis was done by scoring and spatial analysis using GIS techniques. In the end, the results show that the level of disparity in landslide risk is spread across 8 sub-districts in the city ranging from low, medium and high. The highest risk areas are widespread in Gunungpati sub-district, Semarang. Overlay analysis with GIS technology resulted in 563 landslide risk concepts, which were simplified into 16 concepts and were successfully generalized to the new theory of landslide risk. © 2019, World Research Association.
