Abstract

Missile Boat is one of Indonesian Navy Warship (KCR-60) which has a length of 60 meters and made domestically by Indonesian people at the PT. X in Surabaya. Time delay and cost overruns are the problems in the Missile Boat construction project (KCR-60). The purpose of this research was to schedule the time and cost of the project so that it can be completed on time and there is no swelling of costs for the implementation of the construction of the Missile Boats (KCR-60). The scheduling method used in this study was Precedence Diagram Method (PDM) on Network Diagram and Earned Value Method (EVM). Precedence Diagram Method (PDM) was used for scheduling the project time and showing the critical trajectory of project activities along with the acceleration time (Crashing Project) while Earned Value Method (EVM)  was used to determine the costs and time performance and the factors that cause delays or progress of the project. The results showed that the project schedule had 13 activities that had a zero slack or critical activities which were in activities 1, 2, 3, 4, 5, 6, 16, 18, 21, 23, 26, 27, 28. There acceleration of time (Crashing Project) by adding hours of work or overtime for 1 hour every day to 21 activities (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19) will accelerate and reduce the duration of project completion, which was originally 414 days from the completion of the actual work of implementation to 363 days, thus the difference of effectiveness was 51 days (more effective). Meanwhile, for cost efficiency, based on the analysis of the real cost of project implementation, the amount of Rp. 20.407,094,998, - became Rp. 18,410,738,982, thus it became more efficient by Rp. 2,470,548,998, -

Abstract

As an archipelago which has a wider sea area than land, Indonesia, in this case the oil company, must be able to serve and accommodate oil throughout the Indonesian sea, especially the eastern region. The lack of tanker cause the run out of fuel oil in remote areas, so there needs to be a sector division included in oil companies. The method used by researchers was the Analytic Network Process (ANP) approach and the set covering problem method. By determining the right dock location for the Tanker, the dock would be able to cover the entire existing sector, and through the determination of the proper tanker assignment plan, the entire territory of Eastern Indonesia would be able to be covered by the presence of the Tanker. The results of the study show that the candidate starting point assignment was produced by 4 (four) ports as the starting point for the assignment of tankers. These ports consist of Ambon in charge of covering sectors 4, 5, 6 and 7, Makasar port was in charge of sector 1 and to cover sector 3 while Tegal port is in charge of covering the patrol sector 2

Abstract

The Indonesian Navy as a defense and security force of the sea has combat tools and supporting facilities projected in the Integrated Fleet Weapon System (Sistem Senjata Armada Terpadu/SSAT) with several components including Indonesian navy ships, marines, aircraft and bases. Depo level maintenance is comprehensive maintenance that can only be carried out by personnel who are experts in their field and supported by complete and sophisticated equipment and facilities. Maintenance at this level includes complete overhaul repairment, repowering MLM (mid life modernization), calibration of all equipment, and repairs to all parts thoroughly. Depo Level Maintenance is the nature of maintaining technical conditions based on rotary hours. If the repair schedule specified in the SPT (System for Planned Maintenance), the schedule must be carried out. This research aimed to present a priority setting solution in Depo level maintenance wherein the highest Indonesian Navy Ship ranking is determined from the level of the decision makers. Fuzzy MCDM is a method developed for decision making on several alternative decisions to get an accurate and optimal decision. In Indonesian Navy Ship Hardepo priority ranking process taken from the level of data processing decision makers using the Fuzzy MCDM method, the 5 highest priority values in implementation were obtained. Hardepo with the highest scores were KRP-812 0.111, BDU-841 0.108, LAM-374 0.107, KRS-624 0.097 and TJA-541 0.073
