Abstract

PT. INKA Multi Solusi is a subsidiary of PT. Industri Kereta Api is engaged in manufacturing services, manufacture, and trade of spare parts and products for land transportation and the manufacture of railway components according to customer specifications. The product currently being worked on is the type 50 FT flat carriage (UGL) product ordered by the KiwiRail company, Australia, with total production from November 2022 to April 2023 of 791 carriages with a total of 1582 headstock arrangements and a total of 408 units of defects. This study aims to determine product quality and provide suggestions for improving the quality of welding joints for UGL type 50 FT train products. This study uses the Six Sigma method and Failure Mode and Effect Analysis (FMEA). The study result shows that the average Sigma value based on total defects from November 2022 to April 2023 is 3.16, which means that the six sigma target is still unmet. Recommendations for improvements that need to be given are conducting briefings and training for welders so that they are more adept at using the welding machine, cleaning (blasting) the workpiece to remove residual welding impurities, and providing a memo regarding the results of the welding to be given to the next welder.
