Separator is an auxiliary aircraft that serves to separate oil, water and dirt by centrifugal force acting on the basis of differences in specific gravity and oil, water and impurities, so that substances with larger specific gravity will be thrown out first. Knowledge of how to maintain and optimize F.O purifier is important to learn in order to improve the working of the main engine on board. This condition encourages researchers to make a study with the title optimization of F.O purifier to improve the work of the main engine on board the MT. Musi. The purpose of this study is, to determine what factors can improve the performance of the main engine on the ship on the MT. Musi, besides that research aims to know what efforts are done to treat F.O purifier on MT. Musi. This research uses descriptive qualitative method by using data analysis technique of Strengths, Weaknesses, Opportunities, and Threats (SWOT) which is systematic identification of various factors to formulate company strategy. In addition, data collection is done by interview, documentation, observation by observing at the time of overhaul in MT. Musi. The results showed that the treatments performed on F.O purifier regularly and well according to Instruction Manual Book in divided into several periods namely daily maintenance, monthly maintenance, annual maintenance so that the performance of the F.O purifier can work optimally and avoid the occurrence of damage, resulting in fuel which is good quality for diesel motor burning.
