Abstract

Perusahaan Crank Case (PCC) merupakan perusahaan yang bergerak pada bidang manufaktur, dimana salah satunya memproduksi salah komponen dari unit engine motor yaitu komponen crank case. Masih terdapat indikasi pemborosan yang berdampak penurunan efektivitas dan efisiensi proses produksi, yakni presentase defect lebih dari 5%. Oleh sebab itu, perlu adanya optimalisasi di machining process dari crank case dalam upaya peningkatan efektivitas dan efisiensi produksi. Konsep lean manufacturing digunakan pada penelitian ini agar waste di lini produksi machining crank case dapat dieliminasi. Waste Assessment Model (WAM) adalah metode lean manufacturing yang dipilih untuk mengenali waste pada proses produksi. Pengambilan keputusan akan mempertimbangkan cost line sebagai integrasi aspek biaya dalam value stream. Berdasarkan hasil identikasi waste didapatkan 3 waste terbesar yaitu defect, inventory dan transportation. Terdapat 2 alternatif perbaikan untuk mengatasi waste tersebut yaitu dengan cara mengganti jig tool dan mengganti metode push menjadi pull. Hasil penelitian meperlihatkan waste defect turun menjadi rata-rata 4,8%, Total value added cost turun sebanyak 1%, Total non value added cost turun sebanyak 55%.

Crank Case Company (PCC) is a company engaged in manufacturing, one of which produces one component of the engine motor unit, namely the crank case component. In the production process, there are still various indications of waste that cause a decrease in the efficiency and effectiveness of the production process. One of the biggest problems is defects, with a percentage of defects above 5%. Therefore, it is necessary to optimize the process of the crank case to increase the effectiveness and efficiency of production. This study aims to eliminate waste in the production line of crank case by implementing the lean manufacturing concept. The lean manufacturing method used is the Waste Assessment Model (WAM) to distinguish waste in the manufacturing process. The cost integration value stream introduces cost lines that can help facilitate decision-making. Based on the results of waste identification, the 3 largest wastes were found, namely defects, inventory and transportation. There are 2 alternative improvements to overcome this waste, namely by changing the jig tool and changing the push to pull method. The results show that defect waste decreased to an average of 4.8%, total value added cost decreased by 1%, total non-value added cost decreased by 55%.
