Abstract

Tahapan inti dari six sigma adalah Define, Measure, Analyze, Improve, Control. Pada penelitian ini, tahap improve dilakukan dengan perancangan Eksperimen yang bertujuan menghasilkan setting optimal dari faktor mesin yang menjadi penyebab paling potensial terjadinya cacat berdasarkan nilai Risk Priority Number (RPN). Bocor lid dan Pecah cup merupakan cacat yang paling sering terjadi proses. Berdasarkan hasil perancangan eksperimen eksperimen dihasilkan bahwa setting temperatur sealing 255°C dan kecepatan konveyor 75rpm menghasilkan jumlah cacat yang minimum. Peningkatan kualitas terjadi dengan menurunkan DPMO sebelum perbaikan sebesar 13.920 dan nilai sigma 3,6990 menjadi DPMO sebesar 1.892 dan sigma 4,4020. Perusahaan harus terus melakukan pengendalian secara berkesinambungan agar jumlah cacat dapat terus berkurang. Kata kunci: Milk cup, Six Sigma, PDPC, FMEA, Perancangan Eksperimen   ABSTRACT Core phases of six sigma are Define, Measure, Analyze, Improve, Control. In this study, the improve phase to design experiments aimed at generating optimal settings of the factors that cause the machine most potential defects based on the value of the Risk Priority Number (RPN). The leak of cup lids and broken cups are the most occured defects in the process. Based on the results of the design of experiment the setting of sealing temperature at 255 ° C as well as conveyor speed 75rpm produce  minimum number of defects. Improved quality by reducing DPMO occur before and after repair are 13,920 DPMO for sigma value of 3.6990, and 1.892 DPMO for 4.4020 sigma. The Company must continue to exercise control on an ongoing basis in order to be able to continue to decrease the number of defects. Keywords:Milkcup, Six Sigma, PDPC, FMEA,Design Experiment

Abstract

Produktivitas mesin/peralatan yang rendah dapat menimbulkan kerugian bagi perusahaan. Metode Overall Equipment Effectiveness (OEE) merupakan suatu metode pengukuran tingkat efektivitas pemakaian suatu mesin/peralatan dengan menghitung ketersediaan mesin, performansi dan kualitas produk yang dihasilkan. Perhitungan six big losses dilakukan untuk mengetahui kerugian yang mengakibatkan rendahnya nilai OEE. Penelitian yang dilakukan pada bulan April 2014, diperoleh persentase nilai availability terbesar yaitu 92,647% dan yang terendah yaitu 39,706%, persentase nilai performance efficiency terbesar yaitu 85,307% dan yang terendah yaitu 36,225% sedangkan persentase nilai rate of quality product terbesar yaitu 98,713% dan yang terendah yaitu 97,613% dan rata-rata nilai OEE yang dihasilkan pada bulan April 2014 adalah 33,219%. Kata Kunci: Overall Equipment Effectiveness (OEE), Ketersediaan, Performansi, Kualitas Produk, Enam Kerugian Terbesar ABSTRACT Low producitivity of machine/tool can cause company loss. Overall Equipment Effectiveness (OEE) method is a method in measuring the effectiveness of a machine/tool by counting the availability of the machine, performance and quality of the product. Counting six big losses conductedto find out the loss that cause the low OEE value. The research was conducted in April 2014 with the result that percentage of availability is 39,706%-92,647%, percentage of performance efficiency is 36,225%-85,307%, while percentage of rate of quality product is 97,613%-98,713%and the average of OEE value resulted in April 2014 is 33,219%.
