PERBAIKAN MASALAH PADA KOMPONEN ROTARY MESIN JAHIT SNL DENGAN METODE FISHBONE di PT X

PT X is a garment company that specializes in producing underwear, with the majority of its market share in exports. Observations in the D-8 production line reveal machine issues that disrupt the smoothness of the production process. Among the machine problems that arise, the issues with the rotary component of the SNL sewing machine require the longest time for repair and reinstallation. The technical team needs 25 hours to carry out the repairs and adjustments to the machine so that it can be operated again on the D-8 production line. Based on the problem cause analysis method, three causes of the issues with the rotary component of the SNL sewing machine can be identified: human factors, methods, and machines. Field discussion and analysis indicate that the machine factor is the most dominant cause of the issue, specifically due to wear on the rotary hook. The first stage of repair involves a temporary solution by modifying the rotary hook to restore it to its original condition, which can be done by smoothing the rotary hook using sanding. The second stage of repair involves replacing the entire rotary component if the rotary hook can no longer be smoothed.
