Abstract

ABSTRACT Anindya Yessi Nareswari, NIT. 49124652 T, 2017 “Identification of the Causes of Delays in Starting Air System on Diesel Engine with SHEL Method in MT. Serang Jaya/P.3011”, Diploma IV, Teknika, Politeknik Ilmu Pelayaran Semarang, Preceptor I: Amad Narto, M.Mar.E, M.Pd and Preceptor II: Sri Purwantini, S.E, S.Pd, M.M Main engine on board, both diesel engines 4-stroke and 2-stroke air used to start the engine, the air is produced from the air compressor and accommodated in the air reservoir. Air pressure to start this work starts from the pressure of 25-30 bar. Inhibition of starting air on diesel main engine caused the failure of the starting air supply on diesel main engine. The impact resulting from failure of the starting air supply on diesel main engine. This study aims to determine the factors causing the failure of the air supply pedestrian (starting water) and the efforts made to overcome the failure of the starting air supply on the main engine diesel with SHEL method in MT. Serang Jaya. The method used is descriptive qualitative and to identify the problem using the SHEL methods. Descriptive qualitative methods are used to describe the problems that occur with the use of data collection methods such as observation, interviews, documentation, and literature study. SHEL methods used to identify the problems that arise in a system and optimize it with four components: software, hardware, environment, liveware.. The research result are the factors that led to the failure of the starting air on diesel main engine is the lack of air in the air reservoir and starting air valve that is not working/jammed. The impact caused the failure of the starting air on diesel main engine is a disruption of the smooth operation of cruise ships, and can be detrimental to the parties that are in it including the engine crew and the company. Efforts are being made to overcome the failure of starting air on the main engine diesel is to perform maintenance and repairs to the installation of the starting air system damage, such as the suction valve and press on compressors, air reservoir and safety valves and seating starting air valve. Where the damage is caused by the buildup of carbon and corrosion and thereby hinder the work process.. Keywords: Starting Air, Main Diesel Engine, SHEL method
