Disasters are closely related to the social and environment vulnerability. The level of vulnerability is an important factor to asses to know the community and government capacity to deal with disaster. For example, the high vulnerability of the community, infrastructure, and elements in disaster prone areas are also the factors in the occurrence of floods and landslide. This research will study the assessments toward social and environmental vulnerability of landslide threats in Cimanggung District Sumedang Regency West Java Province using qualitative methods. Data obtained in this research was from observation, interview, and study literature. The result in this research shows that social vulnerability in Sumedang Regency was affected by the number of people who do not have an understanding of the potential for landslides. This condition is exacerbated by the high level of poverty in Sumedang Regency which is increasing due to the Covid-19 pandemic. Meanwhile, the environmental vulnerability of Sumedang Regency itself is a horseshoe-shaped area with steeper slopes than other places, hillsides are open land with a lack of strong rooted vegetation and slope reinforcement, and poor drainage so that surface water flows accumulate in the upstream channel. In addition, about 67% of the total area of Cimanggung District, Sumedang Regency is prone to floods and landslides.
