Abstract

Castor (Ricinus communis L) became very popular when discussing environmentally friendly alternative energy. Seeds capable of producing oil producer have the potential to be used as alternative fuel. Oil content in seeds reached 54%. Castor bean oils extraction process using hydraulic press with pre-treatment consists of sorting process and heating with variable preheating temperature of 80˚C, 90˚C, 100˚C and variable pressure of 110 kg/cm2, 120 kg/cm2, 130 kg/cm2. Based on observations made by 9 variables obtained the highest percentage of oil yield is 10.08% (on a heating temperature of 100C with a pressure of 130 kg/cm2) with a moisture content of 3.24%. Density obtained for 0.945 g / ml, the viscosity obtained by the 25.875 cp and obtained by acid number 15,820 mgKOH/g and saponification numbers at 129.591 mgKOH / g. Keywords: Castor, Castor seed oil, Hidraulic press, Pressure
