Abstract

Semakin berkembangnya industri bidang manufaktur di Indonesia menuntut para pelaku industri untuk terus melakukan peningkatan kualitas pada perusahaannya agar dapat bersaing dengan yang lain. Kualitas itu sendiri memiliki fungsi pada perusahaan yaitu meningkatkan reputasi perusahaan, penurunan biaya produksi, peningkatan pangsa pasar, pertanggungjawaban produk, dampak internasional, dan penampilan produk itu sendiri. Produk barang atau jasa yang berkualitas akan menumbuhkan rasa puas pada konsumen sekaligus meningkatkan kepercayaan dan loyalitas konsumen kepada perusahaan. Salah satu perusahaan yang bergerak di bidang industri pengolahan bahan logam adalah PT. X yang bertempat di Surabaya Industrial Estate Rungkut, Jawa Timur. Perusahaan ini bergerak di bidang sheet metal job dan fabrikasi dimana salah satu bahan bakunya yaitu stainless steel diolah sesuai dengan kebutuhan konsumen dan produksi perusahaan. Dalam proses produksinya, PT. X hanya menggunakan tiga jenis bahan baku yaitu mild steel, stainless steel, dan aluminium. Namun walaupun telah didukung dengan mesin produksi yang terotomasi, PT. X masih mengalami berbagai macam permasalahan dalam proses produksinya. Permasalahan-permasalahan tersebut berasal dari eksternal dan internal perusahaan. Untuk menyelesaikan permasalahan di atas, digunakan beberapa metode untuk antara lain activity classification, value stream mapping, operation control chart, E-DOWNTIME, cost of poor quality, pareto chart, root cause analysis, failure mode and effect analysis, dan value engineering. Dengan mengunakan metode pareto chart diketahui waste kritis yang paling berpengaruh adalah waste kategori defect, excess processing, dan inventory. Selanjutnya dirancang alternatif perbaikan menggunakan metode value engineering sehingga didapat alternatif perbaikan dengan kombinasi alternatif satu dan dua. Alternatif tersebut antara lain membuat tim khusus untuk upgrading, sosialisasi tata tertib kerja, dan pembaharuan PDO dengan biaya total sebesar Rp 27.345.000,00 ==================================================================================================== As the manufacturing industries advance forward, the market demands all industries to maintain and improve their production quality in order to be able to compete with competitors. The quality itself has some functions that benefit the company, they are increasing company’s reputation, decreasing production cost, increasing in market share, product responsibility, international impact, and appeareance of the produk itself. The product –goods or services- which has good quality will increase costumer satisfaction. Not only costumer satisfaction but also costumer trus and loyalty. One of industries that run on processing logam material is PT. X which is located in Surabaya Industrial Estate Rungkut, East Java. This company runs sheet metal job and fabrication where one of their raw material is stainless steel. Raw material then will be processed as the costumers demand. The company use three kinds of raw material, they are mild steel, stainless steel, and aluminium. However, although the company has been supported by automated production engine, PT. X still experiences some issues in their production system. Those issues come from the internal and external of the company. To solve the issues mentioned above, the writer use some methods which are activity classification, value stream mapping, operation control chart, EDOWNTIME, cost of poor quality, pareto chart, root cause analysis, failure mode and effect analysis, dan value engineering. By using pareto chart method, the writer acquire critical wastes that affect most of the production system. Those critical wastes are defect, excess processing, and inventory. Next step is designing the improvement alternatives by applying value engineering. By going through that method, the writer acquire first and second improvement alternatives. Those alternatives are creating special team to establish operator upgrading, socializing company rules, and the renewal of PDO. All those alternatives costs approximately Rp 27.345.000,00
