Abstract

Pengendalian kualitas perlu dilakukan atas aktivitas proses yang dijalani untuk menjaga konsistensi kualitas produk serta jasa yang dihasilkan dan sesuai dengan ketentuan kebutuhan pasar. Grafik kendali multivariat Hotelling T2 untuk pupuk ZA I produksi PT. PETROKIMIA GRESIK, diharapkan dapat mendeteksi adanya pergeseran proses statistik dan didapatkan standart proses secara statistik. Selanjutnya, dihitung indeks kemampuan proses untuk mengetahui apakah proses produksi yang berlangsung telah memenuhi spesifikasi yang ditentukan oleh perusahaan ================================================================================================= Quality control need to be performed on the process undertaken to maintain the consistency of products quality, according to the provisions of the needs of the market. Multivariate control chart Hotelling T2, to control the quality of fertilizer ZA I at PT. PETROKIMIA GRESIK, used to improve the detection of mean changes in statistical process control and gets the standart value in statistical process. The next, calculated Index Capability Process to determine weather process production has met the specifications defined by the company
