Abstract

The urgency of this research is how a company is able to obtain better of HR performance, develop knowledge, improve service quality and can create competitiveness for the company. This study objective is to describe whether quality knowledge can encourage technical superintendent motivation so that it can improve technical superintendent work performance during monitoring and evaluation of inventory on board using computer-based applications and knowing quality knowledge can improve technicalsuperintendent work performance so as to realize the performance of monitoring and evaluation of inventory list on board effectively. The method used in this study is the explanatory method. Data collection was carried out online from the distributed instruments. The target population in this study were employees in the fleet division at 7 (seven) shipping companies which were used as research objects with a total number of employees of 160 employees. The data obtained is then tabulated, then data reduction is carried out and after obtaining proper data, calculations are carried out using the SPSS application by carrying out validity tests, variable reliability tests, normality tests and homogeneity tests. According to the results, it is known that there is a strength relationship between the knowledge quality and human resources performance.

Abstract

The diesel engine is an internal combustion engine that produces heat energy and motion energy. Overheating the engine can cause damage. To prevent excessive heat in a diesel engine, cooling is needed, the component that acts as a coolant is a fresh water cooler. normal temperature condition of fresh water cooler is 65ᵒC. The purpose of this study was to find out how maintenance actions are carried out on the fresh water cooler of the main driving diesel engine cooling system if overheating occurs. The research method used in this research is descriptive research, namely research that aims to describe and describe the object under study. Observation of temperature on the control panel of the main engine from the observation of temperature control there was an increase in temperature of 85ᵒC and an alarm sounded so that a fresh water cooler was checked and repaired. This is thought to be caused by the presence of dirt and corrosion in the cooling holes. And at that time, the pressure of the sea water cooling pump decreased from 3.0 kg/cm2 to 2.0 kg/cm2. The research results obtained a blockage in the sea water filter section so it needs to be cleaned and checked so that the incident does not happen again. The conclusion of this research is that the fresh water cooler maintenance on the ship has been going well, carried out according to the machine instructions work instructions, according to schedule. The results of the maintenance are that the engine temperature returns as expected.
