This study examines the decline in incinerator burner performance on MV Geopark Venus as an effort to prevent marine pollution from ship-generated waste. The research used a descriptive qualitative method through direct observation in the engine room, interviews with the Chief Engineer and First Engineer, documentation, and manual book review during sea practice from August 2024 to August 2025. Data were analyzed using a fishbone diagram with the 4M approach, namely Machine, Material, Method, and Man Power. The findings show that burner performance decline was caused by dirty or clogged nozzles, dirty sludge inlet strainer, residue accumulation on the baffle plate and furnace, poor sludge quality, improper flushing practice, and low crew discipline in planned maintenance. These conditions triggered repeated flame failure, unstable combustion, excessive smoke, waste accumulation on board, and potential violation of marine pollution prevention rules. The study implies that periodic cleaning, diesel oil flushing after sludge burning, stricter Planned Maintenance System supervision, and crew refreshment training are essential to maintain incinerator reliability.
