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
