Abstract

Rareness and costly of oil fuel is important reason to developed alternative fuel to substitution of oil especially in Indonesia. Now, Jarak Pagar or Jatropha Curcas exploiting to developed because if his seed extorted can yield the fuel alternative substitution of kerosene and diesel fuel or famous biodiesel title. Biodiesel yielded from jarak pagar seed have more oxygen and calorie value is lower than diesel fuel, so that the process is clean and perfect combustion. Commonly, extortion of jatropha seed can be using whit hydrolik press or screw press. At hydraulic press, the process can not take place continuly so that capacities is not big. Is while, with screw press have enough nicely because the process is continu. Extortion with screw press machine happened because pressure between jatropha seed apart effect from impetus screw. But screw press machine for jatropha seed in this time, most types screw the used is Continues Screw Conveyor where the function of screw just for sending, so that for the process of extortion by using the screw type this rotation of screw is not big (10-30 rpm). That way process the extortion become tardy so that input capacity is small (< 100 kg per hour) see that to one farm hectare can be yielded 4-5 ton of dry jatropha seed. Pursuant to from description, hence designed machine magle of seed apart with capacities of 200 kg /hour. Type screw the used is Cut Flight Screw Conveyor with screw rotation is 60 rpm. From calculation result obtained screw diameter = 6 inches, screw length = 48 inches, amount of screw = 8. System transmission use V-belt and pulley, where V-belt type A (2) and type B. Used motor have the energy of 4,7 kWwith rotation 680 rpm
