Implementasi Six Sigma untuk Mengurangi Defect Kemasan pada Produk Minuman Teh dengan Metode DMAIC di PT XYZ

Abstract

PT XYZ merupakan perusahaan yang memproduksi minuman teh dalam kemasan cup. Pengendalian kualitas penting dilakukan agar menghasilkan produk yang sesuai dan terhindar dari defect. Pengendalian kualitas dapat dilakukan dengan penerapan six sigma metode Define, Measure, Analyze, Improve, dan Control (DMAIC). Tujuan dari penelitian ini adalah untuk mengetahui jenis defect kemasan minuman teh, mengetahui faktor penyebab defect kemasan, dan memberikan usulan perbaikan pada defect kemasan minuman teh. Jenis defect yang ditemukan yaitu cup pecah dan penyok serta seal pecah crack dan robek. Rata-rata nilai sigma sebelum perbaikan sebesar 3,79 termasuk ke dalam kategori rata-rata industri. Defect tertinggi dihasilkan oleh seal pecah crack. Faktor penyebab terjadinya seal pecah crack, yaitu manusia, metode, dan mesin. Usulan perbaikan yang diberikan adalah melakukan pengawasan proses palletizing, melakukan training kepada pekerja loading, membuat standard process loading, melakukan pengecekan mesin Automatic Cup Packaging (ACP), dan mengontrol suhu heater sealer secara berkala. Rata-rata nilai sigma setelah perbaikan sebesar 4,07 termasuk kategori rata-rata industri USA.

PT XYZ is a company that produces tea drinks in cup packaging. Quality control is important to produce appropriate products and avoid defects. Quality control can be carried out by applying the six sigma Define, Measure, Analyze, Improve and Control (DMAIC) method. The aim of this research is to determine the types of tea beverage packaging defects, determine the factors that cause packaging defects, and provide suggestions for improvements to tea beverage packaging defects. The types of defects found were broken and dented cups and broken and torn seals. The average sigma value before improvement was 3.79, which is included in the industry average category. The highest defect is produced by a cracked seal. Factors that cause seal cracks to occur are humans, methods and machines. The proposed improvements given are to supervise the palletizing process, conduct training for loading workers, create a standard loading process, check the Automatic Cup Packaging (ACP) machine, and control the temperature of the sealer heater periodically. The average sigma value after improvement was 4.07, including the US industry average category.
