The efforts to alleviate slum settlement in the coastal areas of Jakarta are required to consider the sustainability of flood disaster protection measures. This is essential for reducing vulnerability issues, particularly in Kalibaru Subdistrict with the highest flood risk. The vulnerability issues refer to aspects of community exposure level, sensitivity, and adaptive capacity as main indicators of coastal areas due to climate change. Therefore, this study aimed to analyze the vulnerability of slum settlement in coastal area of Kalibaru Subdistrict, North Jakarta. A quantitative method was used to measure vulnerability level of settlements to flood using statistical and scoring analysis. The results showed that vulnerability level of settlement to floods was within the moderate category. The adaptive capacity serving as a significant element, was influenced by collective actions, cooperation, and mutual assistance in addressing disaster threats. This showed the need to optimize both physical and non-physical aspects of slum settlement eradication interventions. © 2024 by MIP.
