Abstract
This research aims to analyze quality control in the spark plug production process within the automotive spare part industry using the DMAIC (Define, Measure, Analyze, Improve, Control) method and Failure Mode and Effect Analysis (FMEA). The main problem identified is the high rate of defective products, especially the “dirty body” defect, which accounted for 36% of all defects in 2024. Analysis using Pareto and fishbone diagrams revealed that the primary causes stem from human and environmental factors. The highest Risk Priority Number (RPN) was found in ink viscosity inconsistency (RPN 224). Improvements were proposed through FMEA and the 5W+1H approach, including the addition of a pokayoke system for quality checks, standardized use of protective equipment, and a viscosity parameter study using Zahn Cup #5. After implementation, the dirty body defect ratio decreased from 0.1 to 0.03, These results demonstrate that the application of DMAIC and FMEA methods is effective in identifying root causes and implementing corrective actions that significantly improve product quality. This study contributes to improving quality control in spark plug production and serves as a reference for continuous quality improvement in the automotive industry. Keywords: Quality Control, DMAIC, FMEA, Defect, Spark Plug. Penelitian ini bertujuan untuk menganalisis pengendalian kualitas pada proses produksi busi di industri sparepart otomotif menggunakan pendekatan metode DMAIC (Define, Measure, Analyze, Improve, Control) dan Failure Mode and Effect Analysis (FMEA). Permasalahan utama yang diidentifikasi adalah tingginya jumlah produk defect, khususnya jenis defect "dirty body" yang mencapai 36% dari total defect pada tahun 2024. Melalui tahap Analyze dengan diagram Pareto dan fishbone diagram, ditemukan bahwa faktor utama penyebab defect berasal dari faktor manusia dan lingkungan. Nilai Risk Priority Number (RPN) tertinggi ditemukan pada variabel kekentalan tinta (RPN 224). Berdasarkan temuan tersebut, dirancang perbaikan menggunakan pendekatan FMEA dan 5W+1H, di antaranya adalah penambahan pokayoke untuk interval check, standarisasi penggunaan alat pelindung diri, serta studi parameter kekentalan tinta menggunakan alat Zahn Cup #5. Implementasi perbaikan menunjukkan adanya penurunan rasio defect dirty body dari 0,1 menjadi 0,03 atau turun sebesar 39,5%. Hasil ini menunjukkan bahwa penerapan metode DMAIC dan FMEA efektif dalam mengidentifikasi akar penyebab dan merumuskan perbaikan yang signifikan dalam meningkatkan kualitas produk. Penelitian ini memberikan kontribusi nyata dalam pengendalian kualitas produk busi dan dapat menjadi acuan untuk pengembangan sistem kualitas berkelanjutan di industri otomotif. Kata Kunci : Pengendalian Kualitas, DMAIC, FMEA, Defect, Busi.
