Jatropha

One of the renewable energy sources is Jatropha. Jatropha curcas L which can be processed into bio diesel. The development of Jatropha is expected to create an employment opportunities, grow agro-industry in rural areas, increase empty lands cultivation that will increase farmers income and reduce carbon monoxide emissions (Kyoto-protocol).

The development of Jatropha must be supported by the availability of quality plant material. The recurrent selection of IP2-A population in Asembagus, Situbondo, East Java, with the production standard of 500 capsules / plant / year in year I, has produced IP3-A with an estimated productivity of 2.2-2.5 tonnes of dry beans / ha in the year-I.

In optimal rainfall conditions (1200-1500 mm / year) and adequate nutrient availability, the IP3-A population is capable of producing 5-6 ton / ha in III-year or 8-9 ton / ha in the IV-year to 30-year-old plants. Oil content ranges from 33-36% which varies according to harvest season. Jatropha can be harvested twice a year; but particularly vulnerable in dryland with less than 500 mm / year rainfall or wetlands with rainfall above 2500 mm / year. Flowering jatropha crop is very sensitive to high intensity rain
