Abstract
Kebutuhan plastik di Indonesia masih cukup tinggi, tercatat produksi plastik di Indonesia di tahun 2018 mencapai 4,6 juta ton/tahun. PT. Trias Sentosa Tbk, sebagai salah satu produsen terbesar produk film kemasan fleksibel dengan bahan utama Biaxially Oriented Polypropylene (BOPP) telah mengaplikasikan standar internasional dalam menghasilkan produk yang bernilai tinggi bagi pelanggan, namun pada proses produksi seringkali masih ditemukan kecatatan produk. Pada penelitian ini akan dianalisis karakteristik kualita BOPP menggunakan grafik kendali X-R dan grafik kendali fuzzy X̅̃-R̃. Selajutnya akan ditinjau proses kapabilitas pada setiap karakteristik kualitas. Didapatkan metode fuzzy dengan alpha (α = 0.65) lebih sesuai digunakan jika terdapat kesamaran (pengamatan pada sisi yang berbeda) karena lebih informatif. Selanjutnya proses kapabilitas setiap karakteristik kualitas sudah berada pada batas mampu atau memuaskan, kecuali pada karakteristik stiffness yang memiliki kapabilitas masih kurang baik sehingga disarankan dilakukan perbaikan atau peninjauan kembali.
================================================================================================================================
Plastic needs in Indonesia are still quite high, recorded plastic production in Indonesia in 2018 reached 4.6 million tons / year. PT. Trias Sentosa Tbk, as one of the largest manufacturers of flexible packaging films with the main ingredients Biaxially Oriented Polypropylene (BOPP) has applied international standards in producing high value products for customers however, in the production process it is often found product records/damaged. In this study, BOPP quality characteristics will analyze using X̅-R control chart and fuzzy X̅̃-R̃ control charts. Furthermore, with fuzzy based capability process of each quality characteristic will be reviewed. Obtained fuzzy method with alpha (α = 0.65) is more suitable to use if vagueness exists (observation on different side) because it is more informative. Furthermore, the capability process of each quality characteristic is at the level of being able or satisfying, except for the characteristics of stiffness which have poor capability, so that repairs or reviews are suggested.
