Floods represent the most frequent and costly natural disasters, resulting in significant human, economic, and social losses. In urban areas, extreme flood events are becoming more frequent and severe, necessitating serious attention to flood mitigation and management. The concept of flood resilience introduces a new perspective of living with floods. The Bandung City Government notes that the Gedebage area, particularly at the Soekarno Hatta-Gedebage Road Intersection, has experienced regular flooding since 15 years ago. Nevertheless, this has not dissuaded individuals from residing in the area. Gedebage subdistrict encompasses both residential and economic activities, and thus faces a range of risks that must be considered. Assessing flood disaster risk in urban areas is crucial, as it can help identify areas that require enhanced resilience in the face of disasters. Based on the previous description, it is imperative to assess the level of community resilience or resilience in the face of flooding. This assessment should involve the implementation of several methods for calculating the capacity to reduce flood risk, in accordance with regulatory standards for risk assessment both within and outside the country. In addition to measuring the level of risk, this study will produce a flood risk map for the Gedebage area. The purpose of this research is to provide an overview of the condition of regional capacity, especially in the Gedebage area, and provide alternative solutions for flood control in order to create a future that is more resilient to flood risk within the next 25 years. This research employs a role-playing learning model as a means of mitigating flood risks in the Gedebage area, utilizing the Theory of Planned Behavior (TPB) social approach. The results demonstrated that the Infrastructure Indicator (X2) exhibited the highest score in the descriptive analysis of the continuum line. Prior to flood management, the obtained score was 171, categorizing it as Tending Not Good. Following the implementation of flood management efforts, the score increased to 268, categorizing it as Very Good. This measurement was conducted for educational purposes and, if applied in the community, it is expected to result in significant improvements in flood management infrastructure. This will enable the community to be better prepared and able to better manage flood risks. The results of the analysis of several capacity calculation methods to reduce flood risk show that risk analysis calculations using the Modified Social Capacity Index can reduce flood risk factors. This indicates that Cipadung Kulon, Mekarmulya, and Cisaranten Wetan villages are at a low risk of flooding. This implies that by incorporating indicators from these sources, efforts to mitigate flood risk in the Gedebage area have reached an optimal level. However, Pakemitan urban village has a high level of vulnerability to flooding, thus placing it in the medium risk category. Consequently, it is imperative to implement appropriate mitigation measures and risk management strategies to mitigate the impact of vulnerability to flooding in the area. The alternative solutions proposed to create a future that is more resilient to flood risk within the next 25 years include comprehensive management in the Gedebage Area, which would entail the implementation of effective policies and the allocation of adequate funds from the local government. Another proposed solution is the handling of pre-market fruit waste, which would involve striving for clean conditions without skin. Infrastructural development of water management systems, including the construction of larger and more efficient retention ponds and drainage channels, is a further proposed solution. The development of a mobile application to provide early warnings and information related to weather conditions and river water discharge is also a possibility. Finally, the renovation of the Gedebage Market with a multi-storey market concept to create a modern trading environment is a further proposed solution. These measures are expected to create an environment that is more resilient to flooding and other disasters, as well as improve the quality of life of the people in the Gedebage Area.
