Community-based waste management continues to face challenges in maintaining public participation and program continuity. A similar condition was found in Bojongminggir Village, Pekalongan, where a previous waste bank program had not operated optimally. This community service program aims to implement an EcoMasjid Waste Donation program based on Asset-Based Community Development (ABCD), utilizing plastic bottles as an environmental asset to generate collective benefits for the mosque. The program employed an ABCD approach, with KKN students serving as facilitators and mosque administrators (takmir) and community members acting as local stakeholders. Data were collected through observation, interviews, documentation, and program records, and analyzed descriptively and qualitatively, supported by quantitative data. The program established a mechanism for collecting, sorting, weighing, selling, and recording plastic waste through collection boxes (drop boxes) and a Waste Donation application. Across two collection periods, 66 kg of plastic bottles were recorded and generated total sales of IDR 165,000, comprising 26 kg with proceeds of IDR 65,000 in the first period and 40 kg with proceeds of IDR 100,000 in the second period. The selling price of cleaned bottles could reach IDR 4,000-5,000 per kilogram following improvements in sorting practices. For program continuity, administrative management and routine recording through the application were assigned to the takmir, supported by periodic collection and sorting, role-sharing with youth, and continued cooperation with waste collectors. The EcoMasjid program demonstrates the potential to integrate environmental management, community participation, and mosque empowerment by transforming waste into social and religious benefits
