Abstract

This study discusses the analysis of quality control in the painting process of KOWL pipe steering handle products at PT. Roda Prima Lancar using the DMAIC (Define, Measure, Analyze, Improve, Control) method. The main problem identified is the high number of defective products in the painting process, which has an impact on increasing rework and late delivery. Data from the last six months shows an average defect of 278 units per month from a total production of 90,953 units. Through the application of the DMAIC method, this study begins with problem identification and data collection, followed by an analysis of the main causes of defects using Pareto and fishbone diagrams, then implementing process improvement solutions, and continuous control to maintain the results of the improvements. The results of the study indicate that the DMAIC method is effective in reducing the number of defects and improving product quality. Recommendations are given for this method to be applied consistently to other production lines to support improving the quality and competitiveness of companies in the automotive manufacturing industry. Keywords: DMAIC Method, Six Sigma Method, DPMO, Defect Penelitian ini membahas analisis pengendalian kualitas pada proses painting produk pipe steering handle KOWL di PT. Roda Prima Lancar menggunakan metode DMAIC (Define, Measure, Analyze, Improve, Control). Permasalahan utama yang diidentifikasi adalah tingginya jumlah produk cacat (defect) pada proses painting, yang berdampak pada peningkatan rework dan keterlambatan pengiriman. Data enam bulan terakhir menunjukkan rata-rata defect sebesar 278 unit per bulan dari total produksi 90.953 unit. Melalui penerapan metode DMAIC, penelitian ini dimulai dengan identifikasi masalah dan pengumpulan data, dilanjutkan dengan analisis penyebab utama cacat menggunakan diagram pareto dan fishbone, kemudian implementasi solusi perbaikan proses, serta pengendalian berkelanjutan untuk mempertahankan hasil perbaikan. Hasil penelitian menunjukkan bahwa metode DMAIC efektif dalam menurunkan jumlah defect dan meningkatkan kualitas produk. Rekomendasi diberikan agar metode ini diterapkan secara konsisten pada lini produksi lain untuk mendukung peningkatan mutu dan daya saing perusahaan di industri manufaktur otomotif. Kata Kunci: Metode DMAIC, Metode Six Sigma, DPMO, Defect
