Abstract

The quality control process implements continuous improvements using the Plan Do Check Action (PDCA) method. It uses seven tools where quality control is carried out from the initial production process, ongoing production, and up to finished production. Even though the quality control process has been carried out, the quality of the product is still poor, especially in the area of line spray painting. Data per July-September 2023 recorded 873 defective units with the most dominant spray dust defects with 543 defective units. Using the PDCA method aims to map all the problems above, the purpose of this study is to find out the causes of the most dominant reject spray dust and to find out the factors and determine solutions to reduce spray dust rejection. The PDCA method is used to make improvements that are known. several factors cause spray dust rejection due to the lack of routine maintenance procedures resulting in the performance of the spray gun not being maximized, not cleaning the gun spray every time the process changes which causes the rest of the spray to clog, paint that has expired causing the quality of the paint not to be optimal, lack of control over room temperature and the place for sterilization to enter the spray room is a factor for the large number of rejected spray dust. October-December 2023 recorded a decrease in reject spray dust units from 543 units to 243 units reject.

Abstract

Penelitian ini bertujuan untuk menganalisis penyebab cacat produk pada proses sewing di PT XYZ yang memproduksi pakaian ESD, khususnya Jumpsuit ESD dengan tingkat cacat 5,26% pada April 2024 dari 2090 unit produksi, dengan 110 produk mengalami cacat. Cacat produk yang tinggi pada bulan April 2024 ini akan menjadi fokus utama penelitian. Metodologi yang digunakan adalah pendekatan DMAIC (Define, Measure, Analyze, Improve, Control) yang dikombinasikan dengan Diagram Fishbone dan Failure Mode and Effect Analysis (FMEA). Data dikumpulkan melalui observasi proses produksi dan analisis defect rate selama periode April hingga Juli 2024. Hasil penelitian menunjukkan bahwa jenis cacat dominan adalah jahitan lepas, tepi kain belum dijahit, kancing rusak, dan ritsleting macet. Penyebab utama cacat diidentifikasi melalui analisis akar masalah, dan rencana perbaikan disusun berdasarkan nilai Risk Priority Number (RPN) tertinggi. Strategi pengendalian kualitas yang diusulkan diharapkan dapat mengurangi jumlah cacat dan meningkatkan kepuasan pelanggan terhadap produk yang dihasilkan.

Abstract

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.
