Assessing the Resilience of Coastal Suburbs to Floods Based on Socio-Environmental Factors: A Case Study on Tangerang Coast, Java, Indonesia

Tidal floods are increasingly common along the north coast of Java, significantly impacting coastal areas such as Tangerang Regency. This study evaluates the conditions of flood-prone coastal locations and analyzes resilience to tidal flood disasters in Tangerang Regency, situated adjacent to a metropolitan city. Tidal floods have substantial adverse effects on society and infrastructure, leading to unavoidable damage during occurrences. The research begins with an analysis of land use and land cover (LULC) changes and the pattern of built-up surfaces in Tangerang Regency, utilizing the Random Forest algorithm on Landsat data for classification. Socio-resilience is quantitatively analyzed using a scoring method within a Geographic Information System (GIS), while qualitative analysis employs the Driving Force, Pressure, State, Impact, and Response (DPSIR) framework based on interviews with local inhabitants affected by flooding. The investigation reveals that most subdistricts in Tangerang exhibit low resilience, with only two classified as moderate. Despite this, coastal communities have demonstrated adaptation to flood conditions. The primary objective of this research is to provide valuable insights for residents coping with the challenges posed by tidal floods.
