There was a phenomenon that occurred in garment companies, namely the existence of defect products in the production process. In the sewing process, defects occurred with an average percentage of 6,67% in the first three months of early 2019. This 6,67% was a percentage of disability that exceeded the company percentage limit of 5%, thus disrupting the production process. The primary purposed of analyzing the factors of product defects was to find out the causes and solutions to the company. The Fault Tree Analysis method was used to find out the root caused of product defects. Three main problems caused product defects, namely 1) untidy stitches, 2) stitches that exceeded the specified size, and 3) straightened stitches. By using the Failure Mode Effect Analysis method, the three problems were caused by human error and the absence of a Standard Operating Procedure in the production process. As a solution to problems in the company, the Risk Priority Number value was used. From this study the result obtained 1 Risk Priority Number value is the proposed improvement.

Nowadays, shoes are not just a casual footwear. Certain shoes can tell the social class of a person. The increase of shoe prices and social status of wearing expensive shoes became a trigger for the development of shoe laundry services. There were a service quality problems in a shoe laundry in Tangerang, Indonesia. Several methods to improve service quality was studied and it is decided to propose a new model, which is integration model of Service Blueprint, Failure Mode and Effect Analysis (FMEA) and Fault Tree Analysis (FTA). The research starts with identifying the problem with observation and interview, then build Service Blueprint. Based on the fail point that has been identified in Service Blueprint, the FMEA used to find which process is the most dominant cause of failure and the most urgent for improvement. The next step is using FTA to find the root cause of the failure of the dominant cause. After analyzing the FTA, the improvement was proposed and implemented. Service failure before and after implementation was compared to see the improvements. There are 6 suggestion and implemented. After the implementation, the error in each process was measured and it is found a decrease in error in each process.

<p align="center">PT. Garuda Metalindo, which is engaged in the manufacturing industry, is currently experiencing a product failure of 2.5% in the production process and this exceeds the failure tolerance set by the company, which amounts to 10 units of 1000 units per process function or about 1% in the production process. Failure tolerance that exceeds the limit so that improvements need to be made to reduce the number of product defects in each production process. This study uses Fault Tree Analysis (FTA) to identify the causes of product defects based on the current production process, the next stage using Failure Mode and Effect Analysis (FMEA) to identify potential failures, modes, potential effects of failure, causes of failure, detection modes, and determine the rating against severity, occurrence, and detection on the risk priority number in the production process. Based on the results of the assessment on the RPN, a cold forming process with a score of 576, surface finishing with a score of 512 was obtained, machining 1 with a score of 441, and machining 2 with a score of 392. Proposed improvements for cold forming defects by monitoring and making checking tools (jigs), defect surface finishing by supervising and making product shelves, machining defects 1 with product inspection and making tools for checking (jig), and replacement of drill bit types, machining defects 2 with lamp and insert replacement and periodic inspection. By applying these proposals it is expected to reduce the level of product disability.</p>
