ANALISIS KERUSAKAN KOMPRESOR UDARA TERHADAP SISTEM OLAH GERAK PADA KAPAL KM. LEUSER

Abstract

Air compressor is an auxiliary machinery on board a ship that functions to suction atmospheric air and compress it into air receivers until it reaches high pressure to support the main engine starting process. This study aims to analyze the causes of air compressor damage and its impact on the ship maneuvering system on KM. Leuser, considering the vital role of compressed air in ensuring smooth vessel maneuvers. Using a descriptive qualitative method based on observations during sea practice from August 2024 to August 2025, the research results identified two main issues: the occurrence of cracks in the piston due to contaminated lubricating oil with water, and a decrease in the air receiver charging performance caused by carbon deposit buildup on the suction valve. This condition caused the air receiver charging time to increase from the normal duration of 12–15 minutes to 25 minutes, directly hindering the main engine's readiness during maneuvers such as unberthing. Problem-solving efforts included replacing damaged components, routine cleaning of valves, and implementing systematic maintenance based on the Planned Maintenance System (PMS) to ensure optimal compressed air availability. This research is expected to provide an understanding of compressor functions and routine maintenance of the lubrication system and mechanical components to prevent operational delays and ensure maritime safety.
