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

ABSTRACT The performance of a project can be assessed based on the aspects of time, cost, and quality. The project is said to be successful when it can achieve the goals in the form of these three aspects by the initial planning. But the reality on the ground, often project implementation is not following the plan, resulting in project delays. Contractors can overcome the delay through various methods of accelerating time. This study aims to determine the acceleration of time through the Time-Cost Trade-Off analysis on The Indonesian Navy Jetty Construction Project in Saumlaki (Phase I) by comparing alternative methods of overtime and additional manpower. The analysis was carried out by using a quantitative descriptive method. The data used is secondary data such as of related documents, Bill of Quantity, S Curve, work volume, list of wages, and a number of workers. The calculation results show that acceleration using overtime alternatives can reduce 18 days or 6.98% of the implementation duration with a reduction in costs of IDR. 1,220,546,167.00 of the total cost of implementation (efficiency 1.8%). Additional manpower can reduce the duration for 19 days or by 7.36% with a reduction of IDR. 1,076,481,972.00 (1.61% efficiency). So that in this study it was found that the alternative of working overtime was more efficient than the alternative of additional manpower. Keywords : Scheduling, PDM, Crashing,
