Abstract

Abstrak PT. Indonesia Plafon Semesta adalah perusahaan yang bergerak dibidang produksi dan distribusi material building berupa plafon pvc. Permasalahan yang terjadi bahwa pada proses produksi produk plafon mengalami tingkat kecacatan sebanyak 6.5% per hari, sehingga perlu dilakukan pengendalian kualitas. Penyelesaian permasalahan menggunakan metode Six Sigma dengan tahapan DMAIC (Define, Measure, Analyze, Improve, Control) untuk mengetahui penyebab utama terjadinya produk cacat dan mencoba mengusahakan perbaikan dengan menggunakan konsep FMEA (Failure Mode and Efect Analysis) untuk mengidentifikasi potensi kecacatan bersadarkan nilai RPN. Berdasarkan pada tahap define terdapat jenis kecacatan stiker kurang merekat, ruas patah, pemotongan kurang presisi, sobek atau lekuk, dan gosong atau hangus. Kemudian tahap measure pada P-Chart diperoleh bahwa semua jenis kecacatan berada diatas batas kendali serta perhitungan DPMO memperoleh nilai rata-rata 12.995 dengan tingkat sigma sebesar 3.73 yang munjukkan bahwa berada dibawah nilai standar sigma industri internasional. Lalu tahap analyze berdasarkan diagram pareto yaitu kecacatan stiker kurang merekat dengan presentase 50.3% ,pada diagram Fishbone didapatkan faktor penyebab terjadinya kecacatan dari manusia, mesin, lingkungan, material, dan metode. Selanjutnya tahap improve diperoleh nilai RPN tertinggi yaitu sebesar 240 pada kecacatan gosong atau hangus, maka melakukan analisis berlanjut dengan menggunakan alat bantu 5W+1H. Dan terakhir tahap control maka rencana perbaikan yang dapat dilakukan pada faktor manusia, mesin, lingkungan, material, dan metode. Kata Kunci: Pengendalian Kualitas, Failure Mode Effect Analysis (FMEA), dan Six Sigma ABSTRACT PT. Indonesia Plafon Semesta is a company specializing in the manufacturing and distribution of PVC ceilings, which are essential building materials. However, the production process has encountered a significant issue - a defect rate of 6.5% per day. To address this problem, the company has implemented a rigorous quality control system. The Six Sigma methodology, consisting of the DMAIC (Define, Measure, Analyze, Improve, Control) stages, has been employed to identify the root causes of these defects and implement necessary improvements. Additionally, the FMEA (Failure Mode and Effect Analysis) concept has been utilized to identify potential defects based on the RPN (Risk Priority Number) value. During the define stage, various types of sticker defects have been identified, including less adhesive stickers, broken segments, imprecise cutting, torn or dented stickers, and scorched or charred stickers. Moving on to the measurement stage, it was observed that all types of defects exceeded the control limits on the P-Chart. Furthermore, the DPMO (Defects Per Million Opportunities) calculation yielded an average value of 12,995 with a sigma level of 3.73, indicating that it falls below the international industry sigma standard value. The analysis stage involved the use of a Pareto diagram, which revealed that the most prevalent defect was fewer adhesive stickers, accounting for 50.3% of the total defects. Additionally, the Fishbone diagram helped identify the factors contributing to these defects, which include human error, machine malfunction, environmental factors, materials, and methods. Next, in the improvement stage, the highest RPN value was obtained, notably 240 for burnt or charred defects, so the analysis continued using the 5W+1H tool. Finally, the control stage is a plan for improvements that can be made to human, machine, environmental, material and method factors. Keywords: Quality Control, Failure Mode Effect Analysis (FMEA), and Six Sigma
