MAIDEN ENERGY?, Program Diploma IV, Technical, Merchant Marine Polytechnic of Semarang, Supervising I: Abdi Seno, M.Si., M.Mar.E and Supervising II: Capt. Arika Palapa, M.Si, M.Mar A diesel engine is an internal combustion engine where air is compressed to a sufficiently high temperature to ignite diesel fuel injected into a cylinder, where combustion and transmission drive a piston that converts chemical energy into fuel in mechanical energy. Good disabling is needed on diesel engines, in order to get maximum power. Injector conditions in the main diesel engine driving force is very influential on the condition of the diesel engine itself. The existence of injector damage can affect the condition of the operation of the main diesel engine, so the injector condition must always be maintained. The research method that writer use in the preparation of this thesis is research method of merging between fault tree analysis method and fishbone as data analysis technique to analyze existing problem at main diesel engine of driving, that is what factors causing damage of injector at main diesel engine, what impacts and efforts are being made to overcome the factors of the problem by identifying various factors systematically on human factors, Environment, Method, Machine to formulate the strategy to be taken . Based on the results of research conducted by the author on the MT ship. MAIDEN ENERGY on August 10, 2016 to August 10, 2017, it can be concluded that the injection of the injector in the main engine of the driving force is caused by two factors, namely 1) the high ship operating schedule, and the rarity of maintenance on the main diesel engine driving injector. 2) unsuitable fuel use. To overcome these factors can be done on-time treatment of PMS, as well as good screening on low-quality fuel Keywords: diesel main enginer, injector, fault tree analisys and fishbone.} }
