LOWERING CUSTOMER CLAIM &; NG RATIO ON JACK BRACKET PART USING LEAN SIX SIGMA-DMAIC METHOD AT PT. XYZ
Journal Title: Engineering and Technology Journal - Year 2024, Vol 9, Issue 01
Abstract
PT. XYZ is a manufacturing company that produces Sub Assembly products for two-wheeled and four-wheeled vehicles. Broadly speaking, the stages of the Jack Bracket production process consist of five processes, namely the sharing stage in the Raw Material Line, the Stamping process in the Small Press Line, the Spot Welding Stage in the Welding Assy Line and the Checking Stage in the Final Inspection Line. This research was conducted at Line Assy Welding where the Line produces Jack Bracket parts and Line Final Inspection. Based on NG Outflow &; NG Ratio data in the period July to December 2023, 57 pcs of spot defects were obtained and the number of internal process defects was 32,325 PPM which is equivalent to sigma level 3.3. After applying the six sigma method, the number of NG Customer Claims is nil (0 pcs) and the level of product defects can be reduced to 7,500 PPM which is equivalent to sigma level 4.
