Abstract: This article examines community service initiatives conducted through the Integrated Student Community Service (KKN-Terintegrasi) program at UIN Raden Intan Lampung. This program was implemented at the request of the Mayor of Bandar Lampung, who specifically sought optimal solutions for various local issues, including recurrent flooding within the city. Based on focus group discussions between Student Group 221 and local community stakeholders in flood-prone areas, a sustainable urban development model was formulated, emphasizing active collaboration among the government, academia, the private sector, and civil society. The methodology employed the Asset-Based Community Development (ABCD) framework with a participatory approach. The initiatives of Group 221 focused on three primary pillars: the circular economy, community-based environmental management, and the strengthening of social inclusion. The results demonstrate that collaborative initiatives are capable of producing innovative and sustainable solutions tailored to the needs of the city, while simultaneously fostering collective awareness regarding the importance of urban development oriented toward common welbeing. Keywords: community collaboration; dream city; and sustainable development.
