Abstract
Gula merupakan komoditas terpenting nomor dua setelah beras di Indonesia. Menurut Organisasi Gula Internasional, konsumsi gula Indonesia akan tumbuh 6% per tahun untuk memenuhi kebutuhan 260 juta jiwa penduduk nasional. Saat ini Indonesia memiliki 61 pabrik gula yang seluruhnya menghasilkan gula kristal putih (GKP). Salah satunya adalah PT. Perkebunan Nusantara XI yang merupakan Badan Usaha Milik Negara (BUMN) di bidang agribisnis perkebunan dengan core business gula di Kota Surabaya. Pabrik gula di bawah naungan PT. Perkebunan Nusantara XI dengan kapasitas giling dan hasil produksi terbesar adalah Pabrik Gula Semboro, Jember. Tingkat kemampuan produksi yang sangat tinggi tentu harus diiringi dengan kualitas dari produksi gula, maka perlu dilakukan pengendalian terhadap produk sebagai salah satu cara untuk menjaga dan meningkatkan kualitas dari produk GKP. Dalam penelitian ini, akan dilakukan pengendalian kualitas pada tiga karakteristik kualitas produk GKP menggunakan diagram kontrol Max-MCUSUM, yaitu besar jenis butir (mm), kadar air (%) dan warna larutan (IU). Analisis yang dilakukan memperoleh hasil bahwa proses produksi secara multivariat telah terkendali, tetapi kinerja proses produksi gula kristal putih belum kapabel dengan tingkat akurasi yang rendah, terutama pada karakteristik kualitas kadar air. Sehingga perlu dilakukan perbaikan atau perhitungan kapabilitas proses dengan pembobotan yang berbeda antar karakteristik kualitas.

Sugar is the second most important commodity after rice in Indonesia. According to the International Sugar Organization, Indonesia's sugar consumption will increase 6% per year to fulfill the needs of 260 million citizens nationwide. Currently, Indonesia has 61 sugar factories which all produce white sugar plantation (GKP). One of them is PT. Perkebunan Nusantara XI which is a State-Owned Corporation (BUMN) in the field of agribusiness plantations with sugar core business in the city of Surabaya. Sugar factory under the auspices of PT. Perkebunan Nusantara XI with the largest milling capacity and production is the Semboro Sugar Factory, Jember. The very high level of production capability must be accompanied by the good quality of sugar production, it is truly necessary to control the products as a way to maintain and improve the quality of the GKP products. In this research, quality control will be carried out on three quality characteristics of the GKP products using the Max MCUSUM control chart, namely grain size (mm), moisture content (%), and color of the solution (IU). The analysis conducted shows that the multivariate production process has been controlled, but the performance of the white sugar plantation production process is not yet capable with a low level of accuracy, especially on the characteristics of moisture content quality. So it is necessary to improve or calculate the capability of the process with different weighting between quality characteristics.
