Abstract
Pabrik Gula Tjoekir merupakan salah satu unit pabrik gula yang dimiliki oleh PTPN X. Tingginya tingkat persaingan di dunia industri menuntut setiap perusahaan termasuk industri gula untuk selalu menjaga dan meningkatkan kualitas. Pabrik gula menghasilkan gula yang merupakan salah satu kebutuhan pokok dan sumber kalori yang relatif murah untuk bahan konsumsi. Penelitian ini menggunakan data hasil kualitas gula Pabrik Gula Tjoekir Jombang periode giling Tahun 2016. Sebelum melakukan analisis kapabilitas terlebih dahulu dilakukan pengecheckan menggunakan peta kendali. Peta kendali T2 Hotelling digunakan untuk mengendaliakan mean proses dan peta kendali Generalized Variance digunakan untuk mengendalikan variabilitas proses. Hasil yang didapat yaitu tidak terdapat perbedaan proses pada shift kerja bulan Juni-Juli. Sedangkan untuk perbedaan proses pada phase, terdapat perbedaan antara phase I dan phase II. Hasil peta kendali pada phase I masih belum terkendali secara statistic, sedangkan pada phase II sudah terkendali secara statistik, faktor-faktor yang mempengaruhi ketidaksesuaian produksi dapat diketahui dari diagram ishikawa. Andaikan telah dilakukan perbaikan proses indeks kapabilitas proses secara multivariat dari kedua phase diperoleh secara berturut-turut adalah 1,1 dan 1,319 yang berarti proses produksi gula pada Bulan Juni dan Bulan Juli sudah kapabel.

Tjoekir Sugar Factory is one of the sugar factory units owned by PTPN X. The high level of competition in the industrial world requires every company including sugar industry to always maintain and improve quality. Sugar factories produce sugar which is one of the basic needs and sources of calories are relatively cheap for consumption materials. This research used data of sugar quality of Tjoekir Jombang Sugar Mill in Year 2016 period. Before performing capability analysis, it is done by checking using the control chart. The T2 Hotelling control chart is used to control the process mean and the Generalized Variance control chart is used to control process variability. The results obtained that there is no difference in the process shift work June-July. As for process differences in phase, there is a difference between phase I and phase II. The result of the control chart in phase I is still not statistically controlled, while in phase II it is statistically controlled, the factors that influence the non-conformity of production can be known from the ishikawa chart. Suppose that a process improvement of the multivariate process capability index of both phases has been obtained successively 1,1 and 1,319 meaning that the process of sugar production in June and July is already capable.
