The purpose of this study is to analyze the safety operational process in fiberglass shipbuilding, identify the types of risk causes that hinder the construction of fiberglass boats and propose recommended actions needed to overcome the risks in CV ERA FIBERBOAT by using theoretical research methods. Identification of risks in the process of building new ships, namely employees, materials, work equipment, payment of construction costs, working drawings have revisions. Determining the risk rating of the new ship building process: very high; inappropriate equipment, height; late payment / paying, medium; working drawings have revisions, low; materials arrive late, very low; employees procrastinate. Mitigating risks in the process of building new ships: employees delay work with mitigation, namely the director of the company provides the opportunity for employees to rest so that employees do not get sick, materials arriving late are mitigated by means of shipyard companies providing an easy-to-find address point so that the sender of materials does not having difficulty finding the address of the shipyard, working drawings have revisions that can be mitigated by means the company must always make an existence to the customer in every work process so that there is no miscommunication

This study aims to identify, analyze and mitigate the risks of work accidents at PT Dewa Ruci Agung. Occupational Health and Safety (K3) is very important to be implemented by every company. Prevention of work accidents can be done by knowing the existing risks, one of which is through the Hazard Identification, Risk Assessment and Determining Control (HIRADC) method. The data collection method used in this study uses primary and secondary data. From the results of the study it was found that there were 15 potential hazard risks including the Lifting Process of moving blocks/goods using a crane, the Cutting Process lifting material and placing it on the cutting machine, preparing the cutting machine, the Grinding Process lifting material and placing it in the grinding area, preparing grinding tools, Fitting Process and Working at Height plate installation process, Main Engine (ME) Overhaul Process, New metal seat removal process (ME) using manual tools, Removal process (ME) with Chain block, Cylinder liner (ME) removal process with chain block, Process Welding, Sandblasting and Painting Process, Zinc Anode Process, B3 Waste Disposal Process. Based on the results of the risk analysis, risk identification is then carried out using the HIRADC method which is most likely to reduce the level of risk severity. The risk identification proposed by the researcher is that it is recommended that every worker carrying out the task wear PPE in accordance with the provisions given by the company and the person in charge of the company's K3. So that unwanted events do not occur. Always check tools and Personal Protective Equipment (PPE) regarding their eligibility for worker safety.

This study aims to analyze the effectiveness and the economic side of the process of manual or semi-automatic bending signs. The data required for both types of marking methods are data on the number of operators, company working hours, effective working hours, and the results of the production process. After that it is done by data processing, data processing in this study uses the Experimental Method, in the Manual marking process, the process is done by directly drawing on the multiplex material according to the drawing design using 2 operators, in the Semi Automatic marking process, the use of a CNC machine is done by using only 1 operator and also using a setting on a CNC machine of 50 Amperes. So from the data that has been managed later, it shows that the use of CNC machines as a substitute for manual marking has a positive effect on the company. Which can reduce the amount of operator usage, get more results from the Manual marking process, and use less electricity. So overall, the marking process using the Semi Automatic method is better from all sides compared to the marking process using the Manual method.
 

In this case it refers to the purpose of the content in this final project, namely by compiling a schedule for the Implementation of KM.Mutiara Ferindo 5 Ship Maintenance during the docking process at the PT.PAL Indonesia shipyard. Making a schedule includes what components are repaired when the ship is in a condition shipyard, make a ship maintenance management schedule that has been carried out in the shipyard. The data used in this thesis are data from PT.Antosim Lampung Pelayaran Surabaya and the researchers themselves. The type of data used in this research is primary data. will be related to the problem being studied and the results of the questionnaire distributed to several employees related to this research. In carrying out repairs there is a work list that shows how many items of work work must be done. So this work list has been approved to be carried out in the ship repair process. KM ship repair work. Mutiara Ferindo 5 which carries out planned repairs both at the shipyard and when the ship anchors at sea carries out maintenance technically and economically. Repair work on RO-RO ships that carry out maintenance on a scale that has been determined by the office and ship crew who are authorized to help carry out ship repairs. Repair work on the ship KM. Mutiara Ferindo 5 is well planned in terms of safety equipment and also component equipment that plays an important role in the smooth operation of the ship (maintenance of the entire engine room, deck, safety equipment and maintenance of the inside and outside of the ship). Implementing an economical system of estimating the remaining funds after maintenance at the shipyard.

. In the shipbuilding industry, the repair process is a series of jobs that require a relatively short time. Delays in repairs can occur due to weak management and also caused by less than optimal empowerment of human resources. This study aims to identify the risks found in four divisions, namely the Production Division, Warehouse Division, Finance Division and Purchasing Division. The study found 31 risk events. Determining the value of each risk is carried out using the Failure Mode and Effect Analysis method. There were 13 risks that had the highest Risk Priority Number, namely the length of approval for requests for goods (RPN = 522.88), delays in payment processes by customers (RPN = 504.64), requests for additional work from the owner (RPN = 477.128), fluctuations in the number of manpower (RPN = 454.08), Changes in material use related to the availability of materials in the warehouse (RPN = 411.768), Changes in material calculations related to design (RPN = 389.017), Length of decision making by the owner (RPN = 388.36), Long material delivery process (RPN = 388.36), Insufficient stock material (RPN = 357,588), Writing the amount on the Request for Goods Bill is not detailed (RPN = 357.71), Lack of availability of stock material (RPN = 349,524), Making and submitting late payment requests (RPN = 316.8), Placement of materials that are less efficient (RPN = 296.8) Risk mitigation is carried out using the Fault Tree Analysis method to find the main cause / basic event of each risk. And the mitigation step that needs to be done is by making changes to the warehouse layout. If the layout design of the warehouse is changed to be more efficient it will speed up the material retrieval process which has an impact on the ship repair process time.
 

Work accidents that occur on ships often occur in various cases, one of which is a work accident that occurs in an enclosed space. This is often experienced by a crew member who is unable to understand the proper methods and procedures for working in an enclosed space. Against this background, the researcher conducted a risk assessment of personal safety when working in an enclosed space to find out the causes, impacts and controls of the crew members' lack of understanding and knowledge of personal safety when working in an enclosed space. In this descriptive study using the Job Safety Analysis (JSA) method and the Bowtie method, the researchers obtained very high/extreme (E) scores in carrying out work in closed spaces, namely the ship's crew inhaled poisoned air/gas while checking in the cofferdam tank where these results obtained an likelihood value of 66% and a severity value of 71%. By holding routine drills regarding the application of safety principles in an enclosed space in more detail to all Ship's Crew and at the end of the drill closing displays a training video that displays shows about various accidents that occurred in an enclosed space and the causes of these events are reviewed in detail. So with a more detailed drill on the application of safety principles regarding enclosed space material to all Ship's Crew, it is hoped that it can minimize the occurrence of work accidents in an enclosed space.

Shipyards are often difficult to find information quickly and efficiently on every component of the workplace. A good information system is actually needed for the work process in the shipyard because the project head's planning for the distribution of the project workload being carried out will result in a smooth production process, which will affect the completion time of the work to be carried out. Each of these stages is the final result stage where at this stage the author will draw conclusions to answer the formulation of the packing report based on writing which is prone to loss and damage. The development of an android-based ship repair information system that can be used to quickly and accurately report data required by the central supervisor allows for full monitoring of the new ship building process, which is standard practice in many shipyards that have a research methodology to solve the problem.
 
 

This final assignment compared the results of durations in the CCPM method and the Critical Path Method (CPM) by conducting a case study of ship repairs at Galangan Kapal Madura Ltd. Initial project scheduling employed the traditional method of a Gantt chart, which was then broken down in more detail and complete relationships among activities into CPM form. The results were then compared with the duration in CCPM scheduling by eliminating multitasking and safety time for each activity as well as providing a buffer in progress. The CPM method lasted for 30 days at a cost of IDR 246,600,000.00, while the CCPM method lasted for 20 days at a cost of IDR 215,600,000.00. In conclusion, the CCPM method was the most effective.

In a shipbuilding industry, fast and efficient time is needed in carrying out construction projects and ship repairs. This is because it has been mutually agreed between the two parties, both the owner of the ship (owner), and the shipyard regarding the time to work on the project. By racing on the processing time, the level of productivity is an important point that must be considered by the shipyard. There are many factors that can affect the level of productivity of a shipyard. One of the factors, among others, is the determination of the number of man hours (man hours). In a ship building or repair project, the allocation of the number of man hours is very important, if the number of man hours (man hours) is not correct it will cause delays and decrease in productivity levels. The purpose of this study was to analyze the effect of man hours on the level of productivity in the KMP repair project. Cakalang and KMP. Gili Iyang by conducting a correlation test of the Product Moment method with the help of SPSS (Statistical Program for Social Science) v2.3 for windows software, with the independent variable (X), namely the number of man hours (man hours) and the dependent variable (Y), namely the level of productivity. And then a significant correlation value is generated between the number of man hours (man hours) and the level of shipyard productivity. The results of this study are the significance values obtained between the X and Y variables in the KMP repair project. Cakalang is 0.037 and at KMP. Gili Iyang is 0.026 which means that there is a significant correlation between the variable man hours and productivity with a very strong relationship category in KMP. Cakalang and strong links to KMP. Gili Iyang.
