Biofuel development does not stop at research and production, but also have come to the field trials, particularly for motor vehicles. Trials using biodiesel car diesel engines have been done many times by various parties. The trial began in 2001, Bogor-Jakarta route. The next colossal trials conducted in late 2004 Medan-Jakarta route. The results of trials of labor between BPPT, LRPI, ITB Bandung, and the Department of Agriculture is very satisfactory. In that trial, biodiesel blended diesel fuel with a ratio of 10% biodiesel and 90% diesel. Therefore, biodiesel is named B-10. Biodiesel from palm oil has a number of advantages. In addition to non-toxic and environmentally friendly, for use in motor vehicles do not need to modify the engine. Emissions are also low, do not add to the greenhouse effect, the same energy produced, there is the effect of lubrication, storage easier, and more importantly, the supply is assured.
In Indonesia, tests of biodiesel from used cooking oil or AME ( altfett methyl ester ) in the field has also been carried out with eight motor vehicles are generally less than 2 years (4 cars Opel Corsa-B 1.5 l and 4 cars VW T4 2.4 l) only use AME and diesel by Gadjah Mada University. All VW cars have been designed in accordance with German biodiesel standard (DIN V 51 606 Vornorm).
Testing biodiesel from Jatropha has also already done. Researcher Center for Policy Studies Alumni Association of Industry and Technology 10 November Surabaya Institute of Technology, Dr. Ir. Ibnusantoso Billy, have long been using biodiesel from jatropha for personal automobile consumption. So far, no problems.
Important findings obtained, the converter should be further developed. Consider also the possibility of using a converter on a car berkomposisi 50:50 fuel mixture. As temperatures rise to 19o C, strangeness disappears. Other irregularities encountered when crossing route-Watujaji Sasando, Ngada, NTT. After crossing slope, derivative, and tingkungan sharp, fuel oil 100% pure distance most wasteful (1 liter = 7.4 km). Of the investigation showed, waste caused by the behavior of the driver who often stepped on the gas pedal and AC are kept alive. Meanwhile, two-car comparison test is used to move a more relaxed and most of the trip without air conditioning. After the behavior and use the same AC, the difference in fuel consumption variance only. At that time, 100% pure castor oil is still more extravagant than the other cars.
Based on the calculation of fuel consumption average after-Dempasar Atambua routes show the most extravagant is a 50:50 blend-fueled car, which is 1 liter compared to 8.8 km. A 100% pure castor oil 1 liter versus 9 km, while the 100% diesel 1 liter to 9.2 km. Meanwhile, the calculation of fuel consumption of Atambua-Bandung (3200 km) as follows. Car berkomposisi 100% pure castor oil to spend 312.75 liter, the composition of the mixture of 50:50 as much as 325.5 liter, whereas 100% 286.5 liters of diesel fuel. In general, Robert Manurung concluded, the performance of the vehicle is running well.
In many countries, biodiesel from plants that have been produced, diniagakan, and used as fuel for diesel engines in various mixtures with diesel: B5 (5% biodiesel, 95% diesel), B10, B20, B30 or B100. IN Indonesia, a study conducted ITB named PT Industrial Engineering with the developing process of jatropha biodiesel pilot scale based on 140 liters per batch. Biodiesel is compliant with industry standards and was tested on a variety of diesel vehicles with mileage over 40 thousand km. Biodiesel is also being tested on low-cost generator products Dong Feng 5 kW. Both trials were very good results. Jatropha biodiesel is poured directly on diesel vehicles and diesel generators without being mixed. Apparently, the car's performance does not change with distance using fuel oil. This is because the characteristics of Jatropha biodiesel is not very different or have properties similar to diesel oil. In some ways, a matter of such emissions, biodiesel is superior to the diesel. Sulfur content is much lower making it more environmentally friendly biodiesel.
The chemical structure of Jatropha seed oil consists of triglycerides with a straight-chain fatty acid (unbranched), with or without a double bond. This structure is similar to the CPO. The chemical structure of Jatropha seed oil is very different from the castor oil which has a branch hydroxyl kepyar. These structural differences lead to the use of both oils are also different. Castor oil kepyar more properly used as a lubricant rather than as a fuel.
Jatropha oil is pale yellow and has a high iodine number (105.2 mg iodine/g), which shows unsaturated oil content is high. This is evident from the results of the test-acid composition of castor oil fatty acids. In general, this type of castor oil fatty acids similar to other seed oils. However, oleic linoleic acid content as high as 90%. Chemical structure and composition of Jatropha oil makes better used as a substitute for crude palm oil (CPO) on the applications of non-food. Finally, it stressed, jatropha oil has the potential to replace diesel oil because its cetane value is higher, and the other advantages possessed by castor oil.
I have no doubt that we will be successful in harnessing the sun's energy. If sunbeams were weapons of war, we would have had solar energy centuries ago.

The use of solar energy has not been opened up because the oil industry does not own the sun.

How long can men thrive between walls of brick, walking on asphalt pavements, breathing the fumes of coal and of oil, growing, working, dying, with hardly a thought of wind, and sky, and fields of grain, seeing only machine-made beauty, the mineral-like quality of life?

Living in the midst of abundance we have the greatest difficulty in seeing that the supply of natural wealth is limited and that the constant increase of population is destined to reduce the American standard of living unless we deal more sanely with our resources.
