<p style="text-align:justify;"><strong>Abstract:</strong> A huge potential for biofuel in Indonesia will have the chance to play an important role in the energy mix since the energy supply is highly dependent on fossil fuels. Ethanol, one of the biofuels with a potential to be developed as an automobile fuel in Indonesia, is targeted to supply 5% of total gasoline consumption in 2006-2010. An analysis of environmental impact and cost from production and utilization of a 10% blend of cassava-based ethanol with gasoline, so called E10, was done using Life Cycle Assessment and Life Cycle Cost method, and compared with gasoline. The results obtained showed that E10 has the potential for reducing the global warming and abiotic depletion potentials when compared with gasoline. However, in terms of acidification and eutrophication potentials, E10 has higher impacts than gasoline. The price of E10 is lower than gasoline on a per liter basis; however when comparing the prices based on fuel economy, E10 is more expensive than gasoline. Including external costs in the calculations brings down the E10 price below gasoline.</p><p><strong>Keywords:</strong> LCA, LCC, E10, bioethanol, cassava, Indonesia.</p>
