The sub-district of Cidadap has a high level of vulnerability to landslides, with a characteristic slope of more than 25 % and is overgrown with vegetation. This study aims to identify the effect of changes in land use with vegetative conservation methods that have been carried out in landslide-prone areas in Cidadap watershed. The method used in this research is the Storie Index method. Temporal analysis was carried out on changes in land cover in 1999 and 2019, while spatial analysis was carried out on landslide-prone areas, as well as soil conservation that had been carried out. In this study, there are five variables, namely rainfall, land cover, slope, soil type, and location of landslides. Conservation identification is carried out by overlaying between vegetative conservation and the distribution of landslide-prone areas in the study area. The results of this study indicate that in 1999-2019, land use in the form of settlements and moor/fields has increased. Whereas for the land use class, the types of water bodies, forests, gardens, rice fields, shrubs and empty land decreased. In 1999-2019, Cidadap watershed was dominated by a moderate landslide hazard level with an area of 10,080.49 Ha or 84.92 % of the area of the Cidadap watershed. The conservation that has been carried out in Cidadap watershed uses several combinations of vegetative conservation techniques, namely crop rotation, crop and agroforestry, and agroforestry rotation.
