Abstract

A diesel Generator is equipment has functions as a power generator and electricity supply. Tanker warship is oneof the navy warships applying diesel generator Cummins KTA 38D for electricity supply when going on missionarea or at basecamp. On diesel generator system consists of 7 (seven) sub-system are coolant sub-system,seawater cooling sub-system, fuel oil sub-system, air intake and exhaust sub-system, Lub oil sub-system, Electricstarter sub-system and controlling sub-system. Due high operating hours, the potential for damage is increasing,because damage a component diesel generator. According ship damage report data, the percentage damage ofdiesel generator reach until 38.5% from total equipment damage that occurred during 2016-2022 year. Based onthat phenomena, this research will identifcation factors that cause damage and determine the components havehigh criticality in the diesel generator using the FTA (Fault Tree Analysis) to systematically explain unexpectedcausal factors that lead to failure, and the FMECA (Failure Mode Effect And Criticality Analysis) method to identifycritical components according factors have the highest critical point with calculation of the Risk Priority Number(RPN). The results of calculations and analysis using the FTA and FMECA methods, there are 6 (six) criticalcomponents with the highest RPN value in the diesel generator system, that Tube sea water component (375,4)with the risk of leaking, Impeller components (377,1) with a risk of corrosion/crack, Body Cover SW (372,0) witha risk of corrosion, Mechanical Seals (369,8) with a risk of leaking/damage, strainer (369,1) component with a riskof corrosion, Rectangular seal HE (367,9) a risk leakage and Battery (371,0) with a risk no power electric for startengine.Keywords: Diesel generator, FTA, FMECA, Critical components

Abstract

Projects can be said to be a success or a failure caused by ineffective planning and control, so project activities fail. so there will be delays, decreased quality, and increased implementation costs. The Critical Path Method abbreviated CPM method and goal programming can be applied to manage project completion time more efficiently and effectively. To be able to reduce the impact of project delays and cost overruns through a crash calculation mechanism with three alternative controls; additional labor or overtime work. In this study, the total project age was 277 calendar days, while the project deadline was 284 calendar days, thus the project was delayed for 7 calendar days with a total fine of Rp 25.242.944.400 and a penalty cost is 1/1.000 for the sum of the contract. Based on the data analysis and discussion that has been carried out in this study, the conclusion that can be drawn from his study is the number of days that can be completed in this project using the CPM scheduling method is 257 days. However, without using this method, the project completion time would take 284 days. In addition, the company can save costs of Rp. 181,682,772 while avoiding penalty fees due to project delays. while using goal programming optimization, the optimal time duration is 250 days with a cost efficiency of Rp. 246.092.991. So that by applying the calculation to the CPM method, the company can perform project efficiency for 27 days while using goal programming optimization have project efficiency for 34 days simultaneously being able to streamline the budget by using network planning Keywords: Project Scheduling, CPM, Goal Programming, Critical Path, Time Acceleration

Abstract

Indonesian Naval Academy (AAL) is tasked with organizing the first education for Indonesian Navy volunteer officers at the academy level which produces Indonesian Navy officers who are tanggap, tanggon and trengginas. The purpose of education at AAL is to educate and train cadets to become future Indonesia Navy officers who are professional, able to adapt to science and technology, have a Sapta Marga spirit, and have the skills in accordance with the demands of the initial assignment on the Republic of Indonesia Warships (KRI) and Platoon Commander in the Marine Corps in order to support the duties of the Indonesian Navy. To realize Superior Human Resources, the Indonesian Naval Academy builds an Education system that is oriented towards the Tri Basic Patterns of Indonesia Armed Force Education, namely through Teaching, Training, and Nurturing Methods (Jarlatsuh) which cannot be separated from one another. Based on existing problems evaluation, assessment and development of the AAL education system need to be carried out. Evaluation is carried out using a system dynamic approach and Game Theory, namely by identifying the variables that affect Jarlatsuh and building a causal loop diagram followed by building the main model and its supporting submodels, to develop the AAL Graduate Quality model which consists of 4 (four) sub-models which include: AAL Graduate Quality Submodel. Teaching Submodels. Training Submodels. Nurturing Submodel. then implementing scenarios for intervening variables that need attention and determining policies using the Game Theory method with an approach to cooperative games by adopting the existing system in Japan's NDA. Keywords: Indonesian Naval Academy, NDA, system dynamics, Game Theory
