Abstract. The congested space in a vulnerable urban fisherman kampong settlement is triggered by the inability to compete and the weak empowerment of the kampong's sustainable assets. This situation necessitates a paradigm shifting from the competition between the interests of public and private sector into a harmonious coopetition. By using a case study in Dadap, this study aimed to map the vulnerability, resilience, and sustainability of the vulnerable kampong settlement as a basis for constructing a concept for the kampong's sustainable resilience reinforcement. The research methods consisted of a descriptive qualitative method to analyse the level of the kampong's sustainable resilience and space syntax to simulate the system of the kampong's spatial structure. The results of this research show that reinforcing the resilience of living space and livelihood system of a vulnerable space of an urban kampong fisherman settlement can be done through constructing the triggers in the form of community-based economic empowerment facilities and sustainable coopetition approach through empowering the kampong's sustainable assets with the concept of coworking, co-benefit and co-existence. Regarding the reinforcement of the kampong's structural space system, it can be done through changing its configuration system from intra-space of inner area system to inter-space of area-wide system.
