Abstract

PT XYZ merupakan perusahaan yang bergerak di bidang pipa baja, untuk menghadapi persaingan yang semakin ketat upaya yang dilakukan adalah melakukan pengendalian kualitas dengan menggunakan diagram pareto dan diagram Ishikawa, namun informasi yang didapatkan masih terbatas, sehingga diperlukan peta kendali untuk mengendalikan proses produksi lebih lanjut. Penelitian ini difokuskan pada pipa stainless steel ornamnent, yang bertujuan menganalisis kapabilitas proses pipa stainless steel ornament apakah sudah kapabel atau belum dan faktor penyebab proses produksi tidak stabil dengan menggunakan Peta Kendali T2 Hotelling, Peta Kendali Generalized Variance, diagram pareto, diagram Ishikawa dan kapabilitas proses. Hasil analisis Peta Kendali T2 Hotelling pada perbaikan keempat sudah terkendali, serta kapabilitas prosesnya sudah kapabel karena nilai Cp sebesar 2.64395. Ada beberapa faktor yang menyebabkan proses produksi tidak stabil yaitu posisi roll kurang presisi, cacat roll, kerak pada coil, setel roll, setel weld, kecepatan mesin, debu dan human error. ======================================================================================================= PT XYZ is a company that produce of steel tube, to confront competition that is more strict the efforts is control the quality of do with used diagrams pareto and diagrams of ishikawa, but the information obtained are still limited, so that need for control chart to control the process of the production of further. It is focused on the stainless steel pipe ornamnent, that purpose to analyze capability process of stainless steel pipe ornament has been capable not yet and the factors causing the production process unstable of the T2 Hotelling control chart, generalized variance control chart, diagram pareto, diagram ishikawa and capability process.The results of the analysis T2 hotelling control chart on upgrading fourth already is are under control capabilities, the process is capable because the value of cp equals 2.64395. There ' s a factor causing the production of less volatile precision, a roll roll in,the crush of the coil, set roll, set, speed of machine, dust and human error.
