FOSSIL ENERGY RESOURCES
Around 63% of the Indonesians final energy demand is still depend on oil (more than 60% for transportation sector) (DESDM, 2005) Proven reserve of oil is about 9 billion barrels and with an average production rate of 500 million barrels per year, the reserve will be exhausted in 18 years (DESDM, 2005) Diesel fuel consumption in 2002 reached 24.2 million liters, 40% are imported (US Embassy, 2004) The increase of the international crude oil and fuel price has become a burden to the state budget, due to the subsidizing policy of fuel products. If the current crude oil price stays at around US$60 per barrel, for example, Indonesia has to provide around IDR 89 trillion just for fuel subsidy (Prihandana, 2006)

AIR POLUTION PROBLEMS
Air quality of major cities in Indonesia has been deteriorating especially in the city of Jakarta (Wirahadikusumah, 2003). One of the main contributor of the increases of air pollutant is the transportation sector Ambient air quality monitoring results suggest that NOx , CO and THC are a serious problem in almost all areas of Jakarta. PM10 may be considered as a problem in certain areas and motor vehicles are a major contributor of NOx, PM10, CO and THC emission (more than 70% of each parameter) (Syahril et al., 2002) Implementation of International emission standard (Euro)

Obstacles : Biodiesel producer : Limited number of current biodiesel (FAME) producers which could met the requirement (fuel grade standard, production capacity, experience, product continuity) Price : FAME price is tend to increase and passing the MOPS price ( eg. price of FAME at 10 August 2006 = 108% price of Gas Oil MOPS) Biodiesel still classified as other fuel which is not include in the subsidized fuel category (Price of biodiesel is economical prize and must compete with subsidized conventional fossil diesel fuel)

2. BIODIESEL R&D ACTIVITY IN INDONESIA
1996, LEMIGAS (Oil and Gas Institute), in cooperation with Pertamina (a state own oil company), has tested biodiesel blended with automotive diesel oil (ADO) at a ratio of 30:70 for commercial diesel engine vehicle in 1996 (Legowo, 2005). Currently, Lemigas specializes in the testing methods for biodiesel fuel properties. ITB (Bandung Institute of Technology) has focused its research and development on macroeconomic studies of biodiesel, developing technology for jatropha oil extraction and its conversion to methyl ester. The institute is also focusing on standardization of fuels and on diesel engine test series. The pilot scale biodiesel plant with the capacity of 150 L product per batch was developed by ITB.
Department of Agriculture has worked on biodiesel for several years. Its BB-Mektan (Agricultural Mechanization Research Center) has tested the performance of various blending of biodiesel and ADO on the 5.5 KW stationary diesel engines (Handaka and Agung Hendriardi, 2005). PPKS Medan has also carried out research on biodiesel production from palm oil. In cooperation with ITB, they have conducted road test Java-Sumatra in 2004 which covered a total distance of 2,020 km (Reksowardojo et al., 2005). IPB (Bogor Institute of Agriculture, BPPT Biotechnology Center, Puslitbangbun (Center for Plantation Research and Development, Department of Agriculture) now have actively research in the field of farming technology.
On Farm Technology (Biotech Center BPPT)
Biotech Center BPPT has developed another method of vegetative propagation on some woody plant, including Jatropha curcas, which is known as ex vitro culture. This method adopted the in vitro
micropropagation system outside glass vessels. In this method, rooting was induced directly from the apical shoots of plants, after some treatments, and then producing new plantlets. The plantlet derived from this method can directly acclimatize into the green house. Using this method, the plantlets can be produced in larger number compare to conventional stem cuttings. The ex vitro propagation is a relatively low-cost and simple method to propagate the plant with the same quality as the plantlet produced from in vitro micropropagation.

3. BIODIESEL PRODUCTION TECHNOLOGY
Biodiesel = diesel fuel which contents of methyl/ethyl esters from fatty acids Common reaction :
Glycerides/ + Fatty Acids Methanol/ Ethanol Methyl/Ethyl Ester + Glycerol of Fatty Acids 25 80 C (Biodiesel)
catalyst
Palm Oil Coconut Oil Palm Kernel Oil Animal fat Jatropha Oil Moringa/Kelor Seed Oil Etc.
Natural Oil from Indonesia
Biodiesel product depend on raw material and process quality
BIODIESEL PRODUCT QUALITY IS DEPEND ON RAW MATERIAL AND PROCESS QUALITY
Cetane number, iodine number, cloud point : depend on the fatty acid composition of each raw material Kinematic viscosity, Flash point , Acid number, Ester content, Free glycerol, Total glycerol, Phosphorous content, Sulfur content, Ash content (sulfated ash), and Water and sediment :depend on the processing quality level
BIODIESEL PRODUCTION :
CATALYTIC PROCESS (Low Pressure, Low Temperature, Alkaline Catalyst, Acid Catalyst, Enzymatic) NON-CATALYTIC PROCESS High Pressure, High temperature Low Pressure, High temperature
THE CURRENT BIODIESEL PROCESSING IN INDONESIA :
CATALYTIC PROCESS (Low Pressure, Low Temperature) using Alkaline and Acid Catalyst Basic Consideration : Easier to be handled by operator on minimum requirement skill Can be constructed in small up to medium capacity (< 15 ton/day) High domestic local content

Stability test for biodiesel (methyl esters) made of Indonesian Indigenous raw materials
JAMA (Japan Automobile Manufacturers Association) representative has shown that problems were found in the automobile components that have contact with the fuel, related to the fuels stability Such biodiesel tests however have never been conducted thoroughly on biodiesel derived from Palm oil or Jatropha Curcas Oil. It is necessary to carry out such test to further ensure biodiesel customers and to maintain the infant biodiesel program in Indonesia Objective : to obtain the stability of the biodiesel derived from indigenous raw materials against the factors such as storage, oxidation, temperature and humidity to find alternative measures such as suitable anti oxidants to maintain its stability, as well as economic feasibility providing such measures
