North Denpasar District is one of four districts in Denpasar City, a tourism-based area that faces various challenges, including infrastructure, human resources, and sanitation issues. In response, the Provincial Government of Bali issued Governor Regulation No. 47 of 2019 on Source-Based Waste Management, emphasizing the 3R principles (Reduce, Reuse, Recycle) to minimize waste sent to final disposal sites. This study was conducted in North Denpasar District and focuses on technical aspects and community participation in optimizing the Ubung Gemilang Material Recovery Facility (MRF). The results show that the average waste generation in Ubung Subdistrict is 0.61 kg/person/day, with an average density of 164.91 kg/m³. The waste composition is dominated by plastic (29.21%), followed by leaves and ritual waste (23.5%), and food waste (16.95%). The highest recovery factor (RF) was found in metal (100%), followed by leaves/branches (90.45%) and glass (80.64%). A community participation survey revealed that 58.45% of respondents were willing to manage their waste through the MRF and pay the required service fee. Based on these findings, a service expansion projection was developed through 2034. With projected population growth and increased service coverage, the MRF is estimated to serve 7,255 people, managing up to 4,353 kg of waste per day. To support this capacity, projected equipment needs include two shredders, two screening machines, eight three-wheeled vehicles, and two residual waste containers. While the current total land area of 413.11 m² remains sufficient overall, several operational zones—such as compost maturation, screening, and recycled product storage—are projected to face land shortages. Therefore, optimizing spatial planning within the MRF facility becomes a critical strategy to meet future needs.
