Jatropha curcas

fence pageant ( Jatropha curcas L., Euphorbiaceae) be wood bush plant which many found in tropic area. This plant recognized hardly drought resistance and easy to be multiplied with cutting. Although has is old known as curative material and poison, now s(he more and more gets attention as source of biofuel for diesel engine because its(the seed oil content. Role that is somewhat similar have been long enough been played by nearness consanquinity, tree distance ( Ricinus communis), which its(the seed yielding mixture oil for Iubricant.

Based on observation to variance in nature, this plant believed comes from Middle America, precisely in part of Mexico south, though is found also variance that is enough height in area Amazon. Spreading to African and Asia is anticipated done by the explorers Portugis and Spanyol based on evidence in the form of local name.

Ability to be multiplied in klonal causes variety of this plant not too big. Even though, because s(he is be including crossfertilization plant hence easy to happened recombination of character bringing to variance level that is enough is height.

Seed ( with cochlea) fence distance contains 20-40% vegetable oil, but part of seed core ( seed without cochlea) can contain 45-60% harsh oil. Based on analysis to composition of fatty acid out of 11 provenans fence distance, known that dominant fatty acid is oleic acid, linoleic acid, stearic acid, and Palmitic acid. composition of Oleic Acid and linoleic acid varies, while two remaining fatty acids, coincidence is saturate fatty acid, stays at composition that is permanent relative ( Heller 1996).

Fence distance looked into to draws as source of biodiesel because its(the high oil content, competition doesn't for other exploiting ( for example if it is compared to coconut sawit or sugar cane), and has a real interesting agronomy characteristic.
