Abstract
Propelan merupakan bahan bakar roket, ada dalam bentuk padat maupun cair. Tipe mixer yang biasa digunakan untuk pembuatan propelan adalah tipe horisontal maupun vertikal. Penelitian ini akan memfokuskan pada propelan padat komposit menggunakan mixer horisontal sigma blade. Slurry propelan komposit termasuk fluida non-Newtonian dengan viskositas tinggi. Homogenitas slurry propelan penting untuk diketahui dan dipelajari karena dapat mempengaruhi spesifikasi dan performa propelan yang dihasilkan.Penelitian ini memfokuskan tujuan pada pengaruh mixing time (waktu pencampuran) terhadap homogenitas slurry propelan hasil pencampuran menggunakan mixer sigma blade dan memberikan informasi mengenai perilaku aliran slurry propelan.Perhitungan homogenitas menggunakan data densitas slurry dan densitas propelan. Dari penelitian dan pengolahan data yang telah dilakukan diperoleh hasil bahwa terdapat perbedaan nilai densitas yang signifikan dengan adanya perubahan waktu pencampuran.Kondisi operasi yang menghasilkan slurry propelan paling homogen diperoleh pada waktu pencampuran total135 menit. Untuk perilaku dari slurry propelan didapatkaninformasi bahwa slurry propelan cenderung menunjukkan perilaku fluida pseudoplastik. Penambahan waktu pencampuran memberikan kecenderungan peningkatan viskositas akhir mixing.

Propellant is a rocket fuel that can be solid or liquid. Horizontal or vertical type are the commonused mixer for propellant manufacture. This research will focus on the composite solid propellant by using horizontal sigma blade mixer. Composite propellant slurry is a non-Newtonian fluid with high viscosity. Homogeneity of this slurry is important to study because it can affect propellant specification and performance. The objective of this research was to determine the effect of mixing time to the homogeneity of the propellant slurry that processed bysigma blade mixer and propose an information of propellant slurry flow behaviour.Propellant densities and slurry density were used to assess the homogeneity. Result of data analysis showed that there was significant differences of densities when the mixing time was changed. Operation condition produced the most homogeneous slurry was obtained at total mixing time 135 minutes. The propellant slurryindicated to exhibit pseudoplastic behaviour. Increasing in mixing time has a tendency to increase the end of mix viscosity.
