      Abstract
      Minyak pala mengandung senyawa safrol dan metil eugenol yang teridentifikasi sebagai senyawa toksik. Eliminasi senyawa toksik perlu dilakukan untuk menghasilkan minyak dengan spesifikasi food grade dan meningkatkan harga jual. PT Alam Indonesia Raharja berinisiatif untuk memproduksi minyak pala rendah safrol dan metil eugenol yang belum banyak dijual di Indonesia. Desain proses dirancang menggunakan distilasi fraksinasi vakum. Bahan baku yang digunakan berasal dari daerah Sumatera dan Sulawesi dengan komposisi senyawa berbeda. Desain proses dilakukan melalui simulasi Aspen Hysys dengan skala 100 kg/batch. Kondisi proses menggunakan tekanan 13 mbar serta refluks 2 untuk tahap fraksinasi 1 dan refluks 4 untuk tahap 2. Model termodinamika yang digunakan yaitu UNIQUAC. Desain proses menghasilkan produk dengan dua kategori, yaitu grade A dan B. Minyak pala grade A diproses menggunakan suhu reboiler 120,6 – 133,9? pada tahap fraksinasi 1 dan 153,1– 157,2? pada tahap fraksinasi 2. Minyak pala grade B diproses menggunakan suhu reboiler 120,6 – 133,7? pada tahap fraksinasi 1 dan 140,6 – 150,9 ? pada tahap fraksinasi 2. Hasil simulasi divalidasi menggunakan unit spinning band distillation.
       
      Nutmeg oil contains safrole and methyl eugenol compounds which are identified as toxic compounds. Elimination of toxic compounds needs to be done to produce oil with food grade specifications and increase the selling price. PT Alam Indonesia Raharja took the initiative to produce nutmeg oil with low safrole and methyl eugenol which is not widely sold in Indonesia. The process design was designed using vacuum fractional distillation. The raw materials used came from Sumatra and Sulawesi with different compound compositions. The process design was carried out through Aspen Hysys simulation with a scale of 100 kg/batch. The process conditions used a pressure of 13 mbar, reflux 2 for fractionation stage 1 and reflux 4 for stage 2. The thermodynamic model used was UNIQUAC. The results of the process design produce products with two categories, namely grade A and B. Grade A nutmeg oil is processed using a reboiler temperature of 120.6 - 133.9? at fractionation stage 1 and 153.1 - 157.2? at fractionation stage 2. Grade B nutmeg oil is processed using a reboiler temperature of 120.6 - 133.7? at fractionation stage 1 and 140.6 - 150.9? at fractionation stage 2. The simulation results are validated using a spinning band distillation unit.
