Abstract
PT XYZ merupakan industri manufaktur dalam bidang pembuatan dunnage. Dalam proses produksinya, masih ditemukan pemborosan yang mengakibatkan cacatan pada produk dunnage. Hal ini dapat dilihat pada pengiriman dunnage tahun 2020 memiliki presentase cacat produk sebesar 12%-15% dari jumlah produksi. Peneliian ini bertujuan mengetahui nilai sigma, dan meminimasi cacat serta mengurangi kegiatan yang tidak memberikan nilai tambah. Penelitian ini menggunakan metode Lean Six Sigma. Penelitian dimulai dengan mengidentifikasi pemborosan yang terjadi pada proses produksi dunnage dengan pemborosan paling dominan yaitu defect. Tingkat kemampuan sigma yang didapat dalam proses produksi dunnage di PT XYZ sebesar 3,22 dengan nilai DPMO 46231,89.yang selanjutnya dilakukakan analisa untuk mengidentifikasi penyebab terjadinya defect dengan fishbone diagram dan 5 why. Usulan perbaikan yaing dibuat yaitu menggunakan metode 5W+1H, dan pendekatan 5S serta pembuatan tanda bantu dan tabel form dalam pendekatan 5S. Usulan perbaikan yang berikutnya yaitu mengeliminasi kegiatan yang tidak memberikan nilai tambah dan dipetakan pada Value Stream Mapping (VSM) didapat peningkatan kualitas serta peningkatan efisiensi untuk kegiatan Value Added (VA) dari 96,85% menjadi 97,75%. Serta meningkatkan efisiensi lead time dari 4499,05 menit menjadi 4457,43 menit.

| Additional Information: | PT XYZ is a manufacturing industry in the field of dunnage manufacturing. In the production process, waste was still found which resulted in defects in dunnage products. This can be seen in 2020 dunnage shipments that have a product defect percentage of 12% -15% of the total production. This research aims to determine thevalue sigma, and minimize defects and reduce activities that do not provide added value. This study uses themethod Lean Six Sigma. The research begins by identifying the waste that occurs in the dunnage production process with the most dominant waste, namely defects. The level ofability sigma obtained in the dunnage production process at PT XYZ is 3.22 with a DPMO value of 46231.89. Then an analysis is carried out to identify the cause of the defect with a fishbone diagram and 5 why. Suggestions for improvement are made using the 5W + 1H method, and the 5S approach and making auxiliary signs and form tables in the 5S approach. The next recommendation for improvement is to eliminate activities that do not provide added value and map it to Value Stream Mapping (VSM), which results in an increase in quality and an increase in efficiency for Value Added (VA) activities from 96.85% to 97.75%. As well as increasing the efficiency of the lead time from 4499.05 minutes to 4457.43 minutes. Keywords: Waste, Lean Six Sigma, Sigma Value, Quality, Eficiency, dunnage, 5W+1H. | |||||||||
