For this reason, it is necessary to have a planning and scheduling for shipbuilding so that it is received by the shipowner on time. It is inevitable that in every implementation practice there are various possibilities that can cause delays, such as delays in implementation, design changes, weather effects, delays in material supply, construction failures, and planning errors. This study aims to analyze the scheduling of ship x project and analyze the causes of delays in QCS block project at the PT. Karimun Sembawang Shipyard. Scheduling is made using the Critical Path Method (CPM) and Network Planning will describe the entire list of activities needed to complete the project, the time or duration required for each activity. From the results of the analysis, it was found that the 29-day C scheduling model with a shorter duration. Earned Value Analysis (EVA) helps estimate the cost of a project, the planning process of all activities that must be completed in the project will be easier. The results of the analysis in

However, in its implementation, there is the problem of ship delivery delays in various shipbuilding companies. This research will analyze the risk analysis of the installation of the engine room module system by identifying risk factors and parameters that affect performance as a hazard identification that has the potential to cause delivery delays. The object of the research is the Indonesian Navy's Auxiliary Hospital Ship, which has 6 zones with a pilot project developed in zone 2. This includes an engine room that contains important constructions in the form of a main motor foundation, auxiliary motor, and other machinery, where the system was integrated. Moreover, there are some works consisting of construction, outfitting, and commissioning which are very complicated and require high accuracy. The aim of the implementation of risk analysis of the installation system in the engine room's module is to assess potential risks, the effect of risk on project delays, and project cost overruns. The research method uses a Bayesian network because it is able to assess the most potential risks and predict the possibility of delays at network nodes. The primary risk is associated with electrical activities, specifically electrical outfitting on wiring, clamping, and compound sub-components with a probability of (0.0002560) in the Machinery Outfitting and Electrical Department. This risk stems from inappropriate steps during drawing revisions, which have the potential to cause delays in equipment installation, cable material procurement, and the generation of cable cutting data. Therefore, early coordination with production planning control, design, and the supply chain is crucial.

This was needed by management or ship owners to carry out maintenance planning. The shipyards as repair services, there are often obstacles during the repair process that cause the repair time to be longer. This is caused by limited work equipment, delivery of materials that are not in order, and lack of technical equipment. The purpose of research is to evaluate the risk of ship repair delays so there are no failures or delays in ship repair. The method used is the FMEA method (Failure Mode and Effect Analysis) to measure each failure in each activity that affects ship repair. The results showed an assessment score in the form of a Risk Priority Number (RPN) consisting of activities: amount of cutting machines is still limited with a score of 309.83, painting and welding failures at the same time with a score of 267.08, materials that come are remachined to fit the needs with a score of 335.06 and inadequate transportation equipment with a score of 294.16. Improvements made in the form of preparing amount of work tools before the work is carried out, conditioning the order of work according to the schedule and adding backup transportation.

This study aims to determine the calculation of the Production Cost of aluminum boats using the application of activity-based costing methods. As well as to find out the comparison of the calculation of the Production Cost of aluminum ships with traditional system methods and activity-based costing. At the data analysis stage, this study uses the activity-based costing method. The end result of this study is in the form of data from the results of data analysis from the application of the activity-based costing method, the advantages and disadvantages obtained while using this method.

This study aims to calculate the risk of a shipbuilding project using the Failure Mode and Effect Analysis (FMEA) method. The final result obtained is the result of the calculation of the Risk Priority Number (RPN) in determining what risks can affect shipbuilding work. There are two jobs with RPN value > 200 which are classified as High Risk namely errors in lofting and damage to the pulley block as a supporting tool. The plans for risk management with the highest RPN value are then discussed with th e shipyard. Risk mitigation is carried out on the possible risk of errors in lofting, namely by adding worker personnel in the loft ing workshop who serve as supervisors and examiners. While the risk of breakage of the trough can be overcome by paying attention to the inventory and also the condition of the tool. Dalam pekerjaan pembangunan kapal, risiko terhadap keterlambatan pengerjaan harus bisa dianalisis dan diantisipasi agar keterlambatan tersebut tidak terjadi dan menyebabkan kerugian antar kedua belah pihak. Penelitian ini bertujuan untuk menghitung risiko daripada suatu proyek pembangunan kapal dengan menggunakan metode Failure Mode and Effect Analysis (FMEA). Hasil akhir yang didapat merupakan hasil perhitungan Risk Priority Number (RPN) dalam menentukan risiko apa saja yang dapat mempengaruh i pekerjaan pembangunan kapal. Terdapat dua kemungkinan risiko dengan nilai RPN > 200 yang tergolong dalam kategori High Risk yaitu kesalahan dalam melakukan lofting dan kerusakan takal sebagai alat penunjang. Mitigasi risiko yang dilakukan terhadap kemungkinan risiko kesalahan dalam melakukan lofting yaitu dengan menambah personil pekerja di bengkel lofting yang bertugas sebagai pengawas dan pemeriksa. Sedangkan risiko kerusakan takal dapat ditanggulangi dengan memperh atikan persediaan dan juga kondisi alat.

Maintenance or repair is needed for the ship in order to stay in good condition and fit to sail. In a ship repair project, there are several important aspects that need to be considered in order to complete project activities quickly and precisely. PT. XYZ has carried out ship repair activities, but the repair activities have been delayed due to weather factors, and the late procurement of spare parts. This research was conducted by analyzing the three models of scheduling fiberglass ship repair projects using Microsoft excel and using the CPM (Critical Path Method), PDM (Precedence Diagram Method) and PERT (Project Evaluation and Review Technique) methods. Results from the CPM method on 48-day A scheduling, 33-day B scheduling, and 21-day C scheduling. Pdm method results scheduling A 48 days, scheduling B 33 days, and scheduling C 21 days.
