CDRI (Climate Disaster Resilience Index) for Analysis of Semarang City’s Resilience to Climate Change Disasters

Abstract Semarang City is one of three Coastal Cities in Indonesia, which has quite complex coastal problems. Physically and socially, the city of Semarang faces the risk of global climate change accompanied by population growth. Measuring urban resilience is one of the essential processes for understanding the current and potential future risks of cities to guide the development of appropriate policies and strategies related to climate and disaster resilience. This research aims to measure the level of resilience of Semarang City based on the Climate Disaster Resilience Index (CDRI) parameters in facing disasters related to climate change. The approach used in this research is a quantitative approach, which will be implemented through Focus Group Discussion activities and surveys involving several stakeholders and representatives of each sub-district to measure the resilience index on a sub-district scale. The variables used in determining the resilience index used in this research are the CDRI variables, which include Physical, Social, Economic, Institutional, and Natural Factors. Next, Aggregate Weighted Mean Index (AWMI) methods will be used to calculate the scores for each variable and sub-variable. Based on the research results, among the five variables measured, institutional policy has the highest number, which means that in terms of policy, Semarang City has both written and unwritten rules related to handling climate change disasters. Meanwhile, the lowest value is natural, where natural factors can only reduce the risk but not completely overcome it. The findings reveal that Semarang City exhibits a relatively high level of resilience in certain areas, particularly in institutional policy and social aspects like education and awareness. However, the city faces significant challenges in terms of natural resilience, particularly due to its high population density and the vulnerability of its coastal environment to flooding and sea level rise. The study highlights the need for a multifaceted approach to enhance Semarang City’s climate resilience. This includes strengthening disaster risk and climate risk assessments, revising development policies to incorporate Disaster Risk Reduction (DRR) measures, monitoring development in high-risk areas, and fostering collaboration among stakeholders.
