      Abstract
      Penggunaan biosolar akan meningkat seiring dengan berjalannya program mandatori pemerintah dalam penghematan bahan bakar solar. Namun beberapa persoalan seperti kadar partikulat dan kadar air pada bahan bakar biosolar masih perlu diperhatikan. Salah satu upaya yang dapat dilakukan untuk menangani persoalan tersebut adalah dengan penambahan zat aditif rhodinol dari komponen minyak sereh wangi. Tujuan penelitian ini adalah melakukan desain proses distilasi fraksinasi vakum rhodinol dari minyak sereh wangi dengan kapasitas 500L dan menentukan spesifikasi ukuran desain unit distilasi fraksinasi. Simulasi dilakukan menggunakan software Aspen HYSYS. Hasil simulasi diharapkan dapat memberikan gambaran desain proses fraksinasi yang dapat memenuhi standar berdasarkan validasi data. Simulasi dilakukan dengan kondisi tekanan 4-5 mbar dan variasi rasio refluks 1,2, dan 3. Rasio refluks 2 merupakan hasil simulasi terbaik rhodinol dengan konsentrasi tertinggi sitronelol 47.80% dan geraniol 61.34%. Spesifikasi ukuran desain, untuk pipa diameter maksimum 0.04 m dan minimum 0.02 m dengan ketebalan maksimum 3.7 mm dan minimum 2.8 m. Tinggi kolom 10.5 m, diameter kolom 0.2412 m, dan tebal 3 mm. Panjang condensor 1.11 m, diameter condensor 0.2032 m, panjang reboiler 1.5 m, dan diameter reboiler 0.6515 m.
       
      The application of biodiesel will increase in accordance with the government's mandatory program for saving fossil fuel. The challenging would come from are particulate levels and water content. One of the efforts to fix the issues is by adding rhodinol from citronella oil as an additive. This research was conducted to design vacuum distillation process which has 500L of capacity and determine the design of the fractionation distillation unit. Simulation was carried out using the Aspen HYSYS software. The result of the simulation is expected to provide an overview of the fractionation process that would comply to the standard after some data validation. The simulation was applied by vacuum pressure in 4-5 mbar and variation of reflux ratio 1,2, and 3. The best simulation obtained was reflux ratio 2 at 47.80% geraniol and 61.34% citronellol concentrations. The simulation also obtained the following results are maximum and minimum pipe diameter of 0.04 m 0.02 m, maximum and minimum thickness of 3.7 mm 2.8 m, column height of 10.5 m, column diameter of 0.2412 m, and thickness of 3 mm, condenser length and diameter of 1.11 m and 0.2032 m, reboiler length and diameter of 1.5 m and 0.6515 m.
