Ahmad Saefudin, 2017 , NIT : 50134955 T, “optimalize the decreasing of compression pressure on air compressor in KMP. Asia Inovator by using USG method” , Engineer Studies script , Diploma IV , Semarang Merchant Marine Polytechnic , Instructor 1 : Agus Hendro Waskito, M.M., M.Mar.E. Instructor 2 : Adi Oktavianto, ST.T., M.M.
Air compressor is an assist plane that can produce exerting air pressure that has to get attention and maintenance intensifely and continually , so that the compressor can be well-operated and stable in a long period . if the compressor runs into compression pressure decreasing , the air filling on air bottle will be late and cause the long period of main engine manouvering system , this case is a big disadvantage for any shipping company in general . While the other factor that can cause the decreasing of compression pressure on air compressor is the leakage of suck valve and less maintenance .
Remember compresor is very important at the vessel, and then needed appropriate methods to solve problem damage sucition valve and pressure valve with USG ( Urgent, Seriousness, Growth ) methods that is with method to make a problems of tree to looking for cause of the problem, and added to observation, interview to looking for factor of causes, and the effort should be done.
Therefore , the systematic and arranged maintenance of suck and press valve is a must needed to keep the decreasing of compression pressure on compressor , so that the treatment and maintenance need to be done toward all components that will be discussed by the writer in this script
KEY WORDS : Air Compressor , suck valve amd press valve , USG method.
