Abstract

Rubber (Hevea brasiliensis Muell. Arg) is which one of agriculture product many have developing economic country. Except of latex product, rubber of plantation to production rubber seeds to optimum used not yet. As see oilcontent on rubber seed is very high 45,63% so the rubber seed oil has wide potential aplication. To obtain oil from rubber seed, there are two methods commonly used for oil extraction from rubber seeds, which are mechanical pressing and solvent extraction. Two common methods of mechanical pressing can be used, which are hydraulic pressing and screw pressing. Screw pressing methode had been pretreatment consist of tempering. The objective of this research is to study the “effect of material size and preheating temperature on rubber seed oil yield using screw pressing methode. Therubber seeds are cleaned and the kernels are separated manually from the seeds. after that, rubber seed was size reducted with various 100 mm (+10 mm), 50mm (+10 mm) and 100mesh after that the rubber seeds preheatead with various temperatures 50oC, 60oC and 70oC. The next step is the pressing operation using screw speed 200 rpm. The higherresult from research had oil yield persentation 10,11 % with variations material size at 100mesh and preheating temperature 70oC.moisture content 0,2%, density 0,920 gr/ml, and viscosity 34,476 cp. Keywords : Rubber seed, Screw pressing, Rubber seed oil.
