Analysis of Mak Diesel Engine Services at Merawang Power Plant Using FMEA Method

Abstract

Merawang Diesel Power Plant is one of the power plants that located on Bangka Belitung Islands. PLTD Merawang has many types of engine generators. One of them is the MAK type 8M453 engine generator which produced 2.544 Kilo Watt. The type of routine maintenance in MAK engine are daily, weekly, biweekly and monthly. Although maintenance has good control management, the MAK engine continues to have disruptions and repairs. The frequency of damage that often occured on the MAK engine were the cylinder head component (compression leakage when the engine is operating), valve (overwork), nozzle injector (fogging pressure), and others. In terms of analyzing the disturbances found on MAK engines using the FMEA method. The objective of this paper to identify and eliminate current defects, as well as searching, solving and drawing the best and potential problems from a manufacturing and to minimize the risk of product failures during production. Three major problems occurred at Merawang PLTD were: broken head cylinder; interference valve, broken nozzle injector. The suggestions for preventive maintenance of this major problems are: lubrication system should be changed and checked regularly, lubrication system should achieve valve system level, and nozzle injection should be replaced regularly. For all the old machines at Menerawan PLTD should be changed to new ones.
