Penurunan Defect Leakage Sikat Gigi Elektrik Dengan Six Sigma Dmaic (Studi Kasus PT. PIB)
Keywords:
Kata kunci , Defect, Pareto, Fishbone, DMAICAbstract
This paper condenses a Six Sigma DMAIC project implemented in an electric
toothbrush assembly line at PT PIB, Batam. Baseline January–September 2025
records 967,700 units with 36,281 defects; leakage contributes ≈60% (21,774
units) and becomes the CTQ. Using Pareto, SIPOC, P-Chart, and fishbone, root
causes were traced to unstable air pressure at the leakage tester, rubber-seal
mismatch, missing controlled oiling at top-seal assembly, and operator
variation. Post-implementation (Oct–Dec 2025) DPMO fell from ≈5,356 ppm
(≈4σ) to ≈200 ppm (≈5σ), P-Chart points stayed in-control. These results
demonstrate DMAIC effectiveness to reduce leakage defects and stabilize
process capability.
