| Abstract: | Penelitian ini dilakukan di PT XYZ, sebuah perusahaan manufaktur
komponen otomotif, khususnya sistem pengereman. Fokus penelitian adalah
pengendalian kualitas produk dust cover yang sering mengalami cacat produksi.
Pendekatan yang digunakan adalah metode DMAIC (Define, Measure, Analyze,
Improve, Control), yang didukung oleh alat analisis seperti Check Sheet, Diagram
Pareto, Peta Kendali, Fault Tree Analysis (FTA), dan Failure Mode and Effect
Analysis (FMEA). Hasil analisis menunjukkan bahwa dari Januari hingga Oktober
2024, ditemukan 5.098 unit cacat dari 698.666 unit produksi. Jenis cacat paling
dominan adalah welding bolong dengan kontribusi sebesar 32,8%. Nilai DPMO
sebesar 729,68 dan level sigma 4,68 mengindikasikan bahwa kualitas proses masih
dapat ditingkatkan. Faktor utama penyebab defect adalah tidak adanya standar
ketajaman tungsten. Sebagai solusi, diterapkan One Point Lesson (OPL) dan Check
Sheet pengasahan tungsten untuk memastikan ketajaman tungsten selalu dalam
kondisi optimal. Hasil penelitian ini diharapkan dapat mendukung perbaikan
berkelanjutan dalam menjaga mutu produk di PT XYZ. This research was conducted at PT XYZ, a manufacturing company that produces automotive components, particularly braking systems. The focus of the study is on quality control of dust cover products, which frequently experience production defects. The DMAIC (Define, Measure, Analyze, Improve, Control) method was employed, supported by tools such as Check Sheet, Pareto Diagram, Control Chart, Fault Tree Analysis (FTA), and Failure Mode and Effect Analysis (FMEA). The analysis results showed that between January and October 2024, there were 5,098 defective units out of 698,666 units produced. The most dominant defect type was welding holes, accounting for 32.8% of total defects. A DPMO value of 729,68 and a sigma level of 4,68 indicate that process quality still has room for improvement. The primary cause of the defect was the absence of a standard for tungsten sharpness. As a solution, a One Point Lesson (OPL) and a tungsten sharpening checksheet were implemented to ensure that the welding tool remains in optimal condition. The findings are expected to contribute to continuous quality improvement efforts at PT XYZ. |
