Abstract

ABSTRAK PT Yogya Presisi Tehnikatama Industri merupakan perusahaan yang bergerak di bidang manufaktur, cetakan injeksi plastik. Permasalahan yang dihadapi perusahaan adalah masih terdapat produk cacat dalam proses produksinya sehingga harus diatasi dengan pengendalian kualitas. Pengendalian kualitas dilakukan menggunakan metode Six Sigma dengan tahapan Define, Measure, Analyze, Improve, Control (DMAIC) untuk mengetahui karakteristik cacat produk, faktor yang menyebabkan cacat pada produk dan perbaikan terhadap faktor penyebab cacat tersebut dan metode Failure Mode and Effect Analysis (FMEA) untuk mengidentifikasi potensi kegagalan berdasarkan nilai RPN. Pada tahap define diketahui produk yang dipilih Container GS serta pendefinisian spesifikasi produk, alur penggunaan diagram SIPOC. Tahap measure diketahui terdapat 6 CTQ, persentase cacat tertinggi yaitu jenis cacat variabel dimensi, dilakukan perhitungan nilai DPMO didapatkan sebesar 21,157 dengan nilai sigma sebesar 3.55. Hasil grafik peta kendali p menunjukkan proses produksi belum mencapai kestabilan, tahap analyze pada diagram pareto cacat variabel dimensi sebesar 24% dan cacat scratch sebesar 19%, Berdasarkan diagram fishbone penyebab cacat oleh faktor manusia, mesin, metode, material dan lingkungan. Pada tahap improve hasil analisis FMEA dengan nilai RPN tertinggi dengan nilai 720 cacat jenis komtaminasi faktor material karena terpapar debu, partike asing. Tahap control melakukan rekomendasi perbaikan dari nilai RPN yang tinggi dan usulan pembuatan SOP. Kata Kunci : DMAIC, Failure Mode and Effect Analysis, Pengendalian Kualitas, Six Sigma ABSTRACT PT Yogya Presisi Tehnikatama Industri is a company that specializes in plastic injection molding manufacturing. The company is currently experiencing an issue with defective products in the production process, which needs to be addressed through quality control measures. We use the Six Sigma method for quality control, including the Define, Measure, Analyze, Improve, Control (DMAIC) stages to identify product defects, the factors causing them, and ways to improve them. In addition, we use the Failure Mode and Effect Analysis (FMEA) method to determine potential failures based on the RPN value. During the define stage, the chosen product is referred to as Container GS, and the product specifications are defined, along with the usage flow of the SIPOC diagram. During the measurement stage, it has been identified that there are 6 Critical to Quality characteristics (CTQs), with dimensional variable defects having the highest percentage of defects. The DPMO value is calculated to be 21,157 with a sigma value of 3.55. The p control chart results indicate that the production process has not yet achieved stability. The Pareto diagram analysis reveals that dimensional variable defects account for 24% of the total defects, while scratch defects comprise 19%. The causes of defects, as shown in the fishbone diagram, include human factors, machines, methods, materials, and the environment. In the improvement stage, the FMEA analysis highlights material factor contamination as the highest Risk Priority Number (RPN) value, with 720 defects attributed to exposure to dust and foreign particles. Recommendations for enhancements are made during the control stage based on the high RPN value and proposals for creating Standard Operating Procedures (SOPs). Keywords: DMAIC, Failure Mode and Effect Analysis, Quality Control, Six Sigma
