Abstract

Maintenance management is required and has a very vital role for a KRI types FPB57, considering the type KRI is one Alutsista Navy who have a high frequency activity, as well as the broad range of operations support capabilities are varied so that the automatic machine is also high activity and in the end reliability will decrease. Methodology Failure Mode Effects and Criticality Analysis (FMECA) is a widely recognized tool for the study and analysis of the reliability of the design or process. Many authors in the field have emphasized specifically the usefulness of this method and its limitations. At this writing considering the lifetime of the machine and the elements therein specifically the components of the water coolant pump has had a lifetime of more than 20 years, because it can be said that the components have entered a critical period. Based on the steps Failure Mode Effects and Criticality Analysis (FMECA) through the calculation of Risk Priority Number (RPN), so we can determine the critical components of acquired 9 of 19 chances damage that has critical component is Angular Bearings, Cylindrical Bearings, Spacer Ring, Water Seal, shaft Seal, Seal Slip Ring, Impeller, O'Ring and shaft. These components if damaged can lead to engine breakdown. From the optimization results indicate that the component replacement Cylindrical Bearings have the fastest time, ie 98 days. While the replacement of components with the longest time, which is a component Impeller 134 days. Besides obtain the most optimal replacement time of each component, also produced the cost of replacement is effective, it is proved by the value of the optimal CBR. CBR value for all types of components is less than 1 (CBR <1).Keywords : FMECA, Risk Priority Number, Reliability, Replacement Intervals,CBR.

Abstract

By the development of the time, diesel fuel is made from petroleum which is decreasing in number. Besides that, the emissions produced from burning diesel fuel can also cause air pollution. One of the methods used to minimize the use of diesel fuel and air pollution is by using emulsion fuel. therefore, a precautionary measure is required in preparing a reserve fuel source for Indonesian war ships. And one of the options is with emission diesel fuel. From the results of laboratory trials there was an increase in density, viscosity, flash point, cetane and TAN numbers and a decrease in residue, Lower Heating Value and calorific value. The performance test results show an increase in SFOC and thermal efficiency, but the power, torque and BMEP have decreased. So, it can be concluded that the emulsion HSD has decreased performance but can reduce emissions from the combustion process. So, it is hoped that emission diesel fuel can be used as an alternative as well as a solution to the limitations of diesel fuel in the future, so that it can support tni al operations in the future.

Abstract

The industrial revolution 4.0 requires that one must be able to work with increasingly sophisticated technological developments. The industrial revolution 4.0 emphasizes digital economic patterns, artificial intelligence, big data, robotic or known as the disruptive innovation phenomenon. The problem discussed in this study is how to determine the strategy for developing STTAL. The purpose of this study was to determine the best strategy for developing STTAL using the SWOT analysis method. The results of the study show that the development of STTAL to produce Human Resources that mastered the technology faced the era of industrial revolution 4.0. Namely: a). Increase the quantity and quality of laboratory facilities that are complete in stages according to the priority scale adjusting the available budget by means of regulation, cooperation, coordination and socialization to relevant stakeholders, b). Publication of lecturer and student research in national and international journals is one way to improve the ability and expertise to produce technological products of marine and maritime technology, c). Establish a curriculum for each Study Program based on IQF and lead to the science and technology fields of maritime and maritime technology, d). Establishing the ideal STTAL Organization will be able to support the operational education and development of new Cyber Study Programs. Keywords: SWOT Analysis, STTAL Development, Human Resources, Industrial Revolution Era 4.0.
