    Hydrogen is one of the environmentally friendly fuel, but hydrogen is not available while continuously increasing energi demand and fossil fuel availability becomes more limited. Gap between demand and supply is essential to find alternative fuels. Biodiesel be a substitute for fossil fuels before hydrogen is economically. Biodiesel can be made by mixing vegetable oils or fats with fossil fuel with a ratio of (5-20) wt.% but in a long time effect of this mixture can damage the engine. To overcome the problem, biodiesel can be synthesized via transesterification of oil and alcohol with the aid of acid or base catalyst to produce glycerol and FAME (Fatty Acid Methyl Ester). Challenges faced for the commercialization of biodiesel among others, (1) expensive raw material (edible oil), (2) reaction time and separation of the relatively long time (minimum 15 hours), (3) the use of acid catalysts still leaves the problem of corrosion and corrosion of machine tools and pollution to the environment by the catalyst. To make biodiesel competitive in the market, has tried to use used oil (waste cooking oils, WCO), agricultural waste, and recent studies using microalgae. To shorten the reaction time, reaction was carried out using ultrasonic reactor technology and to minimize environmental pollution to use the solid catalyst. In this paper will be summarized on the adoption of latest technologies in producing biodiesel from used frying oil and microalgae. Keywords: biodiesel, ultrasonic reactor, mi
