Flood has become the recurring and prominent disaster risk in Indonesia's Capital Region, Jakarta. Heavy rain intensity merged with urban development issues, including urbanization, land subsidence, and water recharge land conversion causes the widening of flooded areas across Jakarta, Bekasi, Tangerang, and Depok. This causes the need for communities at risk to catch up in their institutional and non-institutional capacity to cope with the flood impacts during the rainy season each year. Thus, communities have learned to depend less on institutional capacities and invest in community resilience instead. This study assesses the community flood resilience factors found in current literature and compares them with the findings from community cases Kampung Melayu and Kebon Baru Urban Communities (Kelurahan) in Jakarta. This paper aims to validate and contrasts the key contributing factors to community resilience based on the literature and findings from flood-prone communities in two urban communities in Jakarta. Community resilience data were collected through town watching, interviews, and community engagement observation in two months. The study found that prominent factors for resilience within the community in these case study locations are leadership, activism, and volunteerism through periodic capacity building and community engagement activities across all sectors. Moreover, there is a need for mutual acknowledgment between community grassroots organizations and government authorities to enhance and accelerate resilience building.
