Abstract

The happening of crisis energi, specially oil fuel (BBM) which indukasion by the increasing of world price have made many states specially Indonesia require to look for the fuel sources alternative of to be developed in Indonesia. One of the crop have the potency as fuel source is fence castor ( Jatropha Curcas). There is two way used occasionally at press mechanical of seed apart that is hidraulic pressing and press have thread ( expeller pressing). At press hidraulic ( hidraulic pressing) process press cannot be done kontinue, is whilely press have thread ( expeller pressing) will obtain;get the low oil, to obtain;get the big oil hence require to require to boost up the pressure kempa through modification at pitch and screw and also boost up speed of rotation screw. Other way which seldom be used by is combination between press mechanical and ekstraksi pelarut, although the quality yielded by when using the method ekstraksi pelarut enough good, but from very costly production cost facet. There by method combination ekstraksi pelarut inappropriate for middle small industry. See from some appliances press the, hence needed to design the appliance press seed apart the piston systems with capacities of 80 kg/jam with pressure of 2,260 kg/cm2. Appliance press this piston systems can be operated kontinue and during process press take place the distance seed given by theX the warm-up with aqueous vapour ( steam) which is hypodermic from boiler heat waste. Warm-Up aim to to crumple the protein in distance seed. Cloting of protein needed to effesiensi ekstraksi so that oil able to be obtained reach 80% from oil rate found on distance seed flesh. Way of appliance activity press piston systems is bone dry distance seed ( rate irrigate 5%) can be enterred cylinder. the Distance seed in cylinder will experience of pressure of piston effect of motivation of the piston rod moved by flywheel which is its source of power is obtained from diesel motor. Then rotation of diesel motor will distribute to the axis through belt and pully. Little by little distance seeds which have fallen to pieces the effect press will draw away and push the spiral spring on the cylinder cover, so that result the hole dismissal of distance oil cake will open, is while castor oil of is result of press will go out passing the hole go out the castor oil. To get the maximal result press can in repeating shall three rill.
