Abstract

Casting process in P.T. Barindo Anggun Industri produces many rejected products. This condition will be improved by controlling factors, such as pouring temperature, pouring time, and pouring height. The research shows that those three factors give significant effect and minimum number of rejected products is obtained when pouring temperature is set at 1200°C, pouring time at 10 seconds, and pouring height at 10 centimeters. Abstract in Bahasa Indonesia : Proses pengecoran di P.T. Barindo Anggun Industri menghasilkan banyak produk yang cacat. Keadaan ini akan diperbaiki dengan mengendalikan beberapa faktor, yaitu temperatur penuangan, waktu tuang dan ketinggian cawan tuang. Dari penelitian ketiganya memberikan pengaruh signifikan. Jumlah cacat minimum didapatkan bila temperatur tuang 1200°C, waktu tuang 10 detik, dan ketinggian penuangan 10 cm. Kata kunci : desain eksperimen, rekayasa mutu

Abstract

Brake lining always needed in automotive world, so good quality from process maufacturing must be obtained. Brake lining quality must be fulfilled, one of the properties is hardeness. Brake lining hardness correlate with influence their lifetime, the drum or disk lifetime and type of vehichle. To get optimal performance of production, we make experiment from factors that influence the hardness of brake lining and determine level from their factors. Abstract in Bahasa Indonesia : Kampas rem selalu dibutuhkan didalam dunia otomotif, sehingga kualitas yang baik dari hasil produksi perlu didapatkan. Kualitas kampas rem harus memenuhi standar, salah satunya tergantung dari kekerasannya. Kekerasan kampas rem berkaitan dengan umur kampas rem, umur drum atau piringan serta jenis kendaraan. Untuk mendapatkan hasil produksi optimal, maka akan dilakukan eksperimen dari faktor-faktor yang mempengaruhi nilai kekerasan kampas rem dan menentukan level dari faktor-faktor tersebut. Kata kunci: desain eksperimen, kampas rem.
