Abstract

PT.SMX merupakan perusahaan yang bergerak dibidang pengecoran dan produksi paving block, untuk proses pembuatan paving block membutuhkan waktu 1 hari dari bahan sampai selesai. Namun selama proses produksi terdapat beberapa kendala yang menyebabkan kegiatan produksi tidak selalu berjalan dengan lancar. Sebab, ada pemborosan selama proses produksi, masalah utamanya adalah Lead Time. Tujuan dari penelitian ini adalah meminimalkan pemborosan dengan menggunakan value stream mapping . Pada penelitian ini akan menggunakan value stream mapping dan data yang digunakan berdasarkan penelitian langsung, setelah data diperoleh dilakukan analisis peningkatan nilai VA pada Current State Mapping sebesar 1,345 menit, setelah dilakukan perbaikan menjadi 345 menit, NNVA yang 337 menit setelah dilakukan perbaikan menjadi 227 menit, dan nilai NVA yang sebelumnya 90 menit menjadi 25 menit. Minimisasi tertinggi terdapat pada proses penyimpanan sementara di penyimpanan Paving block setelah dicetak sebesar 900 menit dan penyebab utama pemborosan persediaan karena gudang penyimpanan perlu ditata ulang.

Abstract

PT DMI is a company that manufactures electrical panel boxes. There are still defective products that exceed the company's target on the results of the powder coating process. The results of powder coating at PT DMI through CV XYZ. This study used the Six Sigma method with five stages including Define, Measure, Analyze, Improve, and Control (DMAIC). The results of the define phase of this study showed that there were 3 CTQs in the powder coating results. phase measure the average DPMO value is 4107.496 and the average sigma level is 4.175. the analyze phase found 4 factors of the type of defect including humans, machines, methods and machines. In the improve phase, there are 3 recommendations that have been given, namely making a 5w+1H table, SOP and DOE. the control phase will be carried out by providing this improvement proposal to each company. The results of this study were able to minimize problems that occurred with powder coating results at PT DMI.
