. This research was conducted to analyze the quality of the coating process at PT Swadaya Graha using the Failure Mode Effects Analysis (FMEA) method. Primary and secondary data collection was carried out in this research. The research results showed that there were five types of defects, namely polishing marks, orange peel, dustpray, sagging and cracking. Based on the FMEA method, the defect rating is determined based on the resulting cumulative percentage value where the highest value is obtained for orange peel defects at 41.7%. This defect was analyzed and it was found that one of the causal factors was the incorrect application of the spreading rate. This factor is obtained from an RPN value of 120. From this research it can be concluded that the FMEA method can be used as a tool to minimize defects in the coating process and analyze improvements that should be prioritized..

. 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.

CV. XYZ is a manufacturing company whose main product is lightweight concrete bricks made in various sizes. Lightweight concrete brick with a thickness of 10 cm is the product that produces the highest defects compared to other products. The resulting defects have an average of 5% where this value exceeds the company's tolerance limit of 3-4%. Based on these problems, a study was conducted to determine the level of defects of lightweight concrete bricks and to provide suggestions for improvements to reduce defects. The research was conducted using the Seven Tools method and Failure Mode and Effect Analysis (FMEA). The results showed that the defect level of Lightweight Concrete Bricks from the highest to the lowest were chipped, cracked, uncut, and dimensional defects respectively. In addition, it can be seen that the Gompal failure mode with the cause of the disassembly or sorting process is too hard to produce the highest RPN score of 245, so that the recommendations for improvement need to be prioritized first.
