Abstract
PT. Gunawan Dianjaya Steel Tbk merupakan perusahaan saham gabungan yang memproduksi plat baja dengan cara di roll. Semua produksi dijalankan dengan mesin sehingga pada saat proses produksinya bisa saja menghasilkan produk yang cacat. Dalam upaya untuk mengendalikan proses produksi maka diperlukan peta kendali U untuk mengetahui hasilnya. Sedangkan untuk mengetahui kapabilitas proses, pergeseran proses, cacat yang paling dominan, serta akar permasalahan penyebab cacat pada proses pembuatan plat baja maka digunakan analisis kapabilitas proses, pergeseran proses, diagram paretto, dan diagram ishikawa. Data yang digunakan adalah data kecacatan plat baja pada saat proses pembuatan plat di PT. Gunawan Dianjaya Steel Tbk di bulan Januari dan Februari 2014. Jenis cacat yang digunakan yaitu short width, short length, chamber, scale, dan run wavey. Hasil yang didapatkan dari analisis yaitu produksi bulan Januari dan Februari tahun 2014 belum kapabel dan tidak mengalami pergeseran proses dengan jenis cacat yang paling dominan yaitu short width dan scale. Sedangkan akar permasalahan penyebab cacat adalah umur slab, pegawai lelah, kurang konsentrasi, suhu, dan mesin.

PT. Gunawan Dianjaya Steel Tbk is a joint-stock company which manufactures rolled steel plate in a way. All production run with the machines so that when the production process may result in defective products. In an effort to control the production process it is needed control chart U to know the results. As for knowing the capabilities of the process, the shift process, the most dominant defect, as well as the root causes of defects in the manufacturing process of the steel plate used analysis The process capability, process shift, Paretto charts, and diagrams ishikawa. The data used is the data plate defects during the manufacturing process of steel plate in the PT. Gunwanan Dianjaya Steel Tbk in January and February 2014. Defect type used is short width, short length, chamber, scale, and run wavey. Results obtained from the analysis of that production in January and February 2014 are not yet capable and experienced a shift in the process with the most dominant type of defect that is short width and scale. While the root causes of defects are age slab, employee fatigue, lack of concentration, temperature, and machines.
