Abstract

Municipal solid waste management studies increasingly emphasize landfill upgrading and environmental safeguards, yet limited empirical evidence remains on how controlled landfill operations perform under district-level resource constraints and fluctuating waste inflow, creating a gap in operationally grounded evaluations. This study assesses the operational system and environmental management of TPA Batu Terang, the main final disposal facility in Bantaeng Regency, Indonesia, focusing on daily waste inflow dynamics, leachate and landfill gas management, nuisance impacts, social dimensions, and institutional capacity. A qualitative descriptive case study design was applied using field observations and an in-depth semi-structured interview with the Head of the Environmental Agency. Reported waste inflow averaged 27.49 tons/day, periodically increasing to 30–32 tons/day due to routine clean-up programs and increased food and packaging residuals linked to the Free Nutritious Meal (MBG) initiative. The facility implements controlled landfill practices with periodic soil cover, supported by a weighbridge and computerized recording that enables semi-annual reporting and improves accountability. Environmental management is strengthened by a leachate collection system and staged multi-pond treatment (intake–facultative–maturation–biofilter), described as operating within capacity. However, methane utilization remains limited and odor persists as the most salient community concern, typically addressed through reactive covering. Key constraints include aging heavy equipment, limited budgets, human resource needs, and suboptimal source separation. Findings imply that phased improvements prioritizing routine cover discipline, equipment maintenance financing, incremental gas control and monitoring, and upstream waste diversion are essential to reduce impacts and support transition toward an integrated final processing facility (TPAS).

Abstract

Recent hospitality waste studies increasingly promote circular organic-waste treatment, yet empirical descriptions of how hotels operationalize low-cost bioconversion pathways (eco-enzyme fermentation and black soldier fly/maggot production) in day-to-day routines remain limited, particularly in Eastern Indonesia. This study aimed to describe the management of hotel organic waste into eco-enzyme and maggot feed at Mercure Makassar (Makassar City, Indonesia) using a descriptive qualitative design. Data were collected through non-participant observations of kitchen waste flows, in-depth interviews with key hotel personnel (food production, stewarding, housekeeping, engineering, and management), and document review (SOPs, training materials, and relevant local/national regulations). Data were analyzed thematically with iterative coding and triangulation across sources. The findings indicate that the system hinges on (i) source segregation at food-preparation and post-consumption points, (ii) stabilization steps to reduce contamination and odor before processing, (iii) standardized eco-enzyme fermentation using organic residues with sugar/molasses and water ratios commonly reported in the literature (e.g., 1:3:10 or 10:3:1 by weight/volume) and a multi-month maturation period, and (iv) BSF-based bioconversion that rapidly reduces restaurant waste while producing larval biomass and frass as by-products. Implementation is shaped by staff literacy, space constraints, pest-control requirements, and alignment with municipal and national waste-management mandates. Overall, this case demonstrates a feasible, practice-oriented circular pathway for hotels, with implications for SOP development, staff training, and measurable reduction of landfill-bound organic waste in Makassar.
