“PERAWATAN PREVENTIF FRESH WATER GENERATOR DALAM MENINGKATKAN PRODUKSI AIR TAWAR DI MV HL DANGJIN”

Abstract

Fauzan Khalfani Octavian, 2025. " Preventive maintenance of fresh water generator to increase fresh water production on MV HL DANGJIN” A very significant decrease in fresh water production, from normal conditions of 20 tons/day to 13 tons/day on MV HL DANGJIN. This problem occurs due to failure to achieve a vacuum level in the fresh water generator and the occurrence of scaling which causes salt deposits to accumulate on the evaporator walls. This study aims to analyze the causes of the low vacuum level in the fresh water generator and scaling which causes salt deposits to accumulate on the evaporator walls. This study uses a qualitative descriptive method with observation, interview, documentation, and literature study techniques. The results of the study indicate that the application of preventive maintenance based on the instruction manual book can reduce the risk of damage and increase fresh water production and system efficiency. This analysis uses the fishbone method which is a method used to identify, compile, and investigate the main causes of a problem or certain effects to determine the root cause of the problem. This study recommends improving the fresh water production monitoring system and technical training for the crew.
