Abstract
Lubricant is a chemical substance in the form of a liquid that is given between two moving objects to prevent or reduce the occurrence of frictional forces. Lubricants function as a protective layer that separates two surfaces in contact. The lubrication system in the ship's main engine has a role to lubricate the engine components. This system is one of the systems that is very influential in supporting the main engine on the ship which has a very important role for the continuity of the main engine's operation as the ship's propulsion. if a lubrication failure occurs, it will have a direct impact on the performance of the main engine and affect the operation of the ship. To prevent the occurrence of hazards caused by the failure of the lubrication system, a good maintenance schedule analysis is needed. In this study, we will discuss the importance of maintaining the lubrication system for support the performance of PT.Sabang Raya Shipyar Jambi Tugboat Sabang 75 main engine. In the maintenance of this lubrication system it is used to prevent the occurrence of critical components, wear and tear on the lubrication system. Meanwhile, in the maintenance schedule, the ship's operational schedule is considered for decision making so that all activities will be carried out when the ship is not on a voyage. Maintenance of the lubrication components include: oil pump, circulation tank, storage tank, filter (filter), Lo cooler. In addition, the maintenance schedule specified maintenance schedule aims to avoid failure of the lubrication system and all maintenance can be carried out when the ship is not sailing. At low engine temperatures, the viscosity of the lubricating oil tends to increase and the lubricating oil experiences a reduction in volume. It is best if the engine temperature is high, the viscosity of the lubricating oil tends to decrease and the lubricating oil experiences expansion. Changes in temperature cause the lubricating oil to experience changes in volume. The temperature of the lubricating oil is too high, which results in low viscosity, which has a negative impact on the main engine components.The results of this research show that it is important to implement the LO cooler, LO filter, LO pump in the lubricating oil system so that it can run optimally. Keywords: Fuel system, Lube Oil, Maintenance
