Abstract

Dalam bisnis perindustrian saat ini, perusahaan dituntut untuk selalu meningkatkan kualitas produk dan meningkatkan performansi kinerja perusahaan dengan selalu melakukan perbaikan (improvement). Bagi perusahaan manufaktur sektor yang paling penting untuk ditingkatkan performansinya adalah di sektor produksi. Persaingan antar perusahaan juga semakin ketat karena akibat pemberlakuan perdagangan bebas saat ini ditambah dengan life cycle produk yang semakin singkat disertai meningkatnya harapan konsumen terhadap produk. Perusahaan yang harus menerapkan perbaikan adalah PT Loka Refractories. Perusahaan ini adalah perusahaan yang bergerak dalam industri batu tahan api. Di perusahaan ini, lead time dari proses produksi cukup panjang dikarenakan masih adanya non value added activity yang terjadi. Non value added activity ini mengakibatkan terjadinya waste di perusahaan, seperti defect pada pembakaran, waiting karena mesin rusak, excess processing akibat proses yang berulang dan rework, overproduction serta inventory yang tinggi. Untuk menghilangkan non value added activity, digunakan tool Lean Manufacturing untuk mengidentifikasi aktivitas apa saja yang tidak memberikan nilai tambah dan mengeliminasinya. Non value added activity di perusahaan terdapat pada proses persiapan bahan, pembentukan dan pembakaran. Kemudian diketahui tiga waste kritis yang harus diperbaiki, yaitu defect, waiting dan inventory. Kemudian dicari akar penyebab permasalahan dari ketiga waste tersebut. Setelah itu dilakukan perbaikan dengan alternatif perbaikan yang terpilih adalah memberikan pelatihan kepada staff PPC dan Quality Control dengan harapan dapat memperbaiki kondisi eksisting perusahaan serta penambahan divisi maintenance untuk melakukan perawatan dan perbaikan mesin. ========================================================================================================== Nowadays, in industrial business, a company should to increase product quality and increase a company competitive advantage. To reach those goals, a company should do a continuous improvement all the time. The most important aspect to be increased is a production aspect. Besides that, the competition between companies become more challenging due to implementation of free trade regulation and product life cycle that become shorter day by day. Moreover, in this era, the customer expectation about product quality is higher than past. One of the companies that should do some improvement is PT Loka Refractories. PT Loka Refractories is a company that produces a refractories product. In this company, production process lead time is quite long because of non-value added activity. Non value added activity causes waste such as defect on burning process, waiting that caused by broke of machine, excess process that caused by rework process, overproduction and high number of inventory. To eliminate non value added activity, this research uses Lean manufacturing concept to identify activities that cannot give value added for product. Non value added activity in PT Loka Refractories happened on raw material preparation process, forming process and burning process. There are three critical waste that should be improved, defect, waiting and inventory. After identify the waste, this research identify the root cause from it. The last step is suggesting the improvement step for company. The chosen improvement step that suggested by this research is: Give some training to PPC and QC staff with expectation to fix and improve the company performance and additional maintenance division to do the treatment and repair of machines.
