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.

评估沿海灾害的社会脆弱性：班达楠榜市沿海地区的案例研究

班达楠榜市的沿海地区由于位于印度-澳大利亚和欧亚板块的俯冲带内，因此非常容易受到沿海灾害的影响。此外，巽他海峡阿纳克喀拉喀托火山的存在进一步增加了该市海岸遭受自然灾害的脆弱性。本研究分析了班达楠榜市沿海地区当前的社会脆弱性。目的是为该市的灾害管理和政策规划提供一个起点。为了确定班达楠榜市沿海地区的社会脆弱性水平，通过叠加人口、人口密度、性别比和抚养比四个指标来绘制社会脆弱性地图。数据表明，班达楠榜市沿海地区的社会脆弱性水平存在显着差异。具体而言，班达楠榜市沿海地区的 25 个村庄中有 8 个表现出高度的社会脆弱性。班达楠榜市沿海地区的 Bumi Waras、Pesawahan 和 Keteguhan 村庄的社会脆弱性最高。研究显示，人口规模和抚养比指标对社会脆弱性水平影响最为显着。这些研究结果预计将为利益相关者减少沿海地区社会脆弱性的努力提供宝贵的意见。
