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.
