Jayapura (ANTARA News) - Papua`s lands provide many oil-yielding plants for biodiesel as one of environmentally friendly renewable energy sources, a researcher has said.
Lands in Papua have a variety of potential oil-yielding crops which can be processed into biodiesel, but so far only oil palm and coconut have been commercially developed, a researcher from the Indonesian Institute of Sciences (LIPI), Tatang H.Soerawidjaja, said in a speech at the First International Biodiversity Conference on Sustainable Development in Papua here recently.
"Oil palm can produce 45 to 70 percent of oil from its pulp and kernel. It can also be consumed by human beings," explained Tatang.
There is also a coconut which can produce 60 percent oil from its kernel which can be consumed and processed into biodiesel.
Other plants are bintangur (Callophyllum inophyllom), pongam (Pongamia pinnata), horseradish (Moringa Oleifera) and Jatropha curcas whose seed kernels can be produced into energy sources.
Meanwhile, other highland plants are buah merah (Pandanus conoideus), kelapa hutan (Pandanus julianetti), sunflower (Helianthus annuus) and rapeseed (Brassica napus).
Tatang pointed out the first generation biodiesel which is produced from pure plant oil is processed by means of transesterification using methanol or ethanol.
Energy produced from the raw materials can be used for electricity generating plants for such a small community as village.
In order the develop biodiesel as a source of bioenergy source optimally and sustainably, particularly in Papua, Tatang said, identification on species of local oil-yielding crops is needed as it can also conserve the natural ecosystem.
Bioenergy development is also expected to give a contribution to social life and improve the economy of Papua`s natives who mostly live in villages.
Those potential plants should also help efforts meet local people`s food resilience in line with bioenergy development efforts, he said. (*)
