Abstract

Using the Lean and Green Six Sigma Method at PT. XYZ, this Painting Process aims to Reduce Tosou Butsu Alloy Wheel Defects Iwan Oktavianto1*, Ellysa Nursanti2, Fuad Achmadi3 Malang National Institute of Technology, Malang, East Java, Indonesia E-mail: khafi.raihan14@gmail.com ABSTRACT Aluminium wheels are a significant component of the automotive industry, but opinions about their quality are primarily based on how they look. As a result, finishing is crucial to the production process in the wheel industry. Efforts must be made to reduce the frequency of Tosou Butsu flaws in the painting process, which most frequently occur in the paint section, even though there are still a lot of errors in the wheel production process. Therefore, to lessen the chance of Tosou Butsu faults developing during the wheel finishing process, the Lean & Green Six Sigma technique is applied. Measure, Analyze, Improve, Control, and Define are the five stages of the Six Sigma methodology (DMAIC). Conversely, the Six Sigma level has grown from 3,417σ, which was the level before the Sigma was repaired, to 3,750σ in Sigma level 3 conditions, or level 4 conditions, with the potential for Tosou Butsu defects to occur at 12104 for a million production processes. Six Sigma is then applied to in this investigation, the painting procedure was able to lower the percentage of Tosou Butsu faults from 0.0276 to 0.0121. In order to optimize efficiency and focus on system mechanisms that align with standard operating procedures and human resource development, the Six Sigma process needs to be applied regularly and refined until the Sigma level reaches 6σ. Keywords: Lean and Green Six Sigma, DMAIC, FMEA, Defect Tosou Butsu. Mengurangi Defect Tosou Butsu Alloy Wheel pada Proses Pengecatan Menggunakan Metode Lean And Green Six Sigma di PT XYZ Iwan Oktavianto1*, Ellysa Nursanti2, Fuad Achmadi3 Institut Teknologi Nasional Malang, Malang, Jawa Timur, Indonesia * Email untuk Korespondensi: khafi.raihan14@gmail.com ABSTRAK Pada proses pengecatan alloy wheel, terdapat beberapa jenis defect yangsering terjadi, salah satunya adalah defect tosou butsu. Tujuan penelitian ini adalah untuk mengurangi tingkat defect (cacat) pada proses pengecatan alloy wheel di PT XYZ menggunakan pendekatan Lean and Green Six Sigma. Penelitian ini menerapkan pendekatan kuantitatif dalam metodologi penelitiannya. Pengumpulan data dilakukan melalui survei yang melibatkan observasi langsung dan dokumentasi. Setelah data terkumpul, data kemudian dianalisis. Hasil dari penelitian menemukan bahwa untuk mengurangi tingkat cacat pada proses pengecatan alloy wheel di PT XYZ, dapat diterapkan dan dijalankan mekanisme sistem pengendalian yang telah dikembangkan untuk memastikan bahwa setiap subproses dapat dijalankan dengan terkendali,mencegah terjadinya cacat berulang, serta untuk memastikan produk Alloy Wheel diproduksi sesuai standar yang ditetapkan. Kata kunci: Defect Tosou Butsu Alloy Wheel, Pengecatan, Lean and Green Six Sigma
