Abstract
PT. X merupakan salah satu perusahaan terbesar di Indonesia yang bergerak dalam bidang industri rokok yang sukses memproduksi produk-produk terbaik, dimana salah satunya adalah rokok Z yang baru diproduksi pada bulan Maret 2017. Sebelum produk ini diluncurkan ke masyarakat, perusahaan harus melakukan 3 inspeksi terhadap produk tersebut, inspeksi secara fisik, kimia dan organoleptik. Inspeksi secara fisik yaitu dengan mengukur pressure drop, diameter pek, diameter kepala dan berat rokok dimana bentuk fisik pada rokok dapat mempengaruhi kenyamanan dan kenikmatan konsumen dalam mengonsumsi rokok. Selama ini hasil inspeksi secara fisik baru dilakukan analisis statistik yaitu dengan menggunakan statistika deskriptif, oleh karena itu hasil inspeksi tersebut akan dilakukan analisis statistik inferensia agar dapat digunakan untuk membuat suatu keputusan. Untuk mengetahui apakah proses pembuatan rokok sudah kapabel atau belum maka digunakan peta kendali Generalized Variance dan T2 Hotelling dimana hasilnya menunjukkan pada Bulan Nopember 2017 (fase I) dan Bulan Desember (fase II) telah terkendali untuk variabilitas dan mean proses, serta kemampuan proses produksi pada Bulan Nopember 2017 sebesar 3,87 dan Bulan Desember 2017 sebesar 3,34 sehingga dapat dikatakan proses kapabel. Ketidaksesuaian sering terjadi dikarenakan faktor material kualitas tembakau yang terlalu kering, manusia yang kurang teliti, mesin yang macet dan sudah tua, metode pengawasan operator kurang dan lingkungan yang gelap dan kurang udara segar.
Kata Kunci : Kapabilitas Proses, Peta Kendali Generalized Variance, Peta Kendali T2 Hotteling
============================================================
PT. X is one of the largest companies in Indonesia engaged in the cigarette industry that successfully produce the best products, one of which is a new Z cigarette produced in March 2017. Before this product is launched to the public, the company must perform 3 inspections of the product the physical, chemical and organoleptic inspection. Physical inspection is by measuring pressure drop, pocket diameter, head diameter and weight of cigarette where the physical form in cigarettes can affect the comfort and enjoyment of consumers in the consumption of cigarettes. During this new physical inspection results performed statistical analysis that is by using descriptive statistics, therefore the results of the inspection will be done inferencing statistical analysis in order to be used to make a decision. To determine whether the process of making cigarettes is capable or not, the Generalized Variance and T2 Hotelling control charts are used where the results show in November 2017 (phase I) and December (phase II) have been controlled for variability and mean process, as well as production process capability at Month of November 2017 amounted to 3,87 and December 2017 of 3,34 so it can be said of process capabel. Nonconformities often occur due to material factors of tobacco quality are too dry, humans are less thorough, machines are jammed and old, less operator supervision methods and dark environment and less fresh air.
