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 kualitas produk BOPP menggunakan grafik kendali X-R dan grafik kendali X-R berbasis fuzzy . Selajutnya dengan berbasis fuzzy akan ditinjau proses kapabilitas 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 yang masih kurang baik sehingga disarankan dilakukan perbaikan atau peninjauan kembali
