Permasalahan utama pada molase adalah tingginya kandungan kalsium yang dapat menurunkan hasil fermentasi dan menyebabkan pengotoran peralatan industri. Salah satu cara untuk meningkatkan kualitas molase sebagai bahan baku fermentasi di industri monosodium glutamat adalah dengan proses dekalsifikasi. Tujuan dari studi ini adalah untuk mengevaluasi konversi reaksi dekalsifikasi dan persen massa kalsium karbonat pada produk reaktor tunggal model continuous stirred tank reactor (CSTR) dan reaktor ganda yang disusun seri (CSTR kaskade) dengan total waktu tinggal yang sama. Studi ini menggunakan pendekatan simulasi proses dengan membandingkan konfigurasi CSTR tunggal dan CSTR kaskade pada slurry tank tanpa mengubah total volume dan waktu tinggal. Hasil simulasi menunjukkan bahwa penggunaan CSTR kaskade meningkatkan konversi reaksi dekalsifikasi dari 97,79% menjadi 99,71% serta menurunkan persen massa kalsium karbonat pada produk dari 1,26% menjadi 0,16% dibandingkan dengan CSTR tunggal. Penerapan konfigurasi CSTR kaskade direkomendasikan untuk meningkatkan efisiensi proses dekalsifikasi molase sebelum fermentasi molase.
