Kemiri Sunan Benefits
Tight and wide canopy holds the raindrop from falling directly to the soil surface so that it reduces erosion and increase the water absorption into the soil. Its roots are also able to prevent the landslides. Additionally, its leaves are so dense (thousands of leaves) that can absorb carbondioxide and release oxygen in a great volume. This means it helps to cope with The Global Warming problems.
As a source of alternative energy…
The seedcor of Kemiri Sunan can be processed into Kemiri Sunan crude oil and could become the source of alternative energy as biodiesel in replacement to Diesel Oil from fossil. The remaining of the extraction as solid waste can be processed into BioGas. From 3 kgs of the solid waste can produce 1.5 m3 of BioGas and that equals to 1 litre of kerosene. Finally, The waste from BioGas can be used as urea fertilizer
Develop people’s economy…
Eventually, the end products could help the community in terms of kerosene consumption reduction and fertilizer. In more financial terms, with productivity assumption for each Kemiri Sunan tree of more than 7 years, it can produce more or less 300 kg dry seeds yearly. The price of dry seed ranges from Rp. 300 to Rp 500 per kg. So, the yearly income for each tree would be from Rp. 90.000 to Rp. 150.000. If each Ha has 50 trees, then the total income would be from Rp. 4.500.000 to Rp. 7.500.000 per year.
Besides the ability of the kernel to produce oil 45 to 56 % of its contyent, after being processed initially to extract bio-fuel the remaining can derive varnish, soap, linoleum, tung oil, resin, synthetic rubber, cloth oil, lubricant, abrasive and mixture for polsher, food and medicine protector, cover for wire and other metal used for radio, radar, telephone, telegraph instrument (Duke, 1978).
