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.
 

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.
