Assessing Social Vulnerability to Coastal Hazards: A Case Study of Bandar Lampung City Coastal Area

Bandar Lampung City's coastal area is highly susceptible to coastal hazards due to its location within the subduction zone of the Indo-Australian and Eurasian tectonic plates. Additionally, the presence of the Anak Krakatau volcano in the Sunda Strait further increases the vulnerability of the city's coast to natural disasters. This study analyses the current social vulnerability in the coastal area of Bandar Lampung City. The aim is to provide a starting point for disaster management and policy planning in the city. To determine the level of social vulnerability in the coastal area of Bandar Lampung City, social vulnerability mapping is conducted by overlaying four indices: population, population density, sex ratio, and dependency ratio. The data indicates that there is significant variation in the level of social vulnerability among the coastal areas of Bandar Lampung City. Specifically, 8 out of 25 villages in the coastal area of Bandar Lampung City exhibit high levels of social vulnerability. The villages of Bumi Waras, Pesawahan, and Keteguhan have the highest levels of social vulnerability in the coastal area of Bandar Lampung City. As revealed by this study, the indicators of population size and dependency ratio have the most significant impact on the level of social vulnerability. These findings are expected to provide valuable input to stakeholders in their efforts to reduce social vulnerability in coastal areas.
