An Overview of Bioethanol Application Made from Biomaterial Ingredient For Stove and Motorcycle

Most of Indonesian people were motorcycle user, whereas it consumed subsidized fuel beside domestic energy consumption. Energy crisis with increasing population number had already forced an alternative energy applied as a solution in the world, involved in Indonesia. Nevertheless, applied of renewable energy on motorcycle was rarely in Indonesia nor for domestic consumption. Bioethanol was one of renewable and a promising alternative energy used for replacing fossil fuel. Ethanol from nature or biological ingredient, known as bioethanol mostly used three materials contained; starch, glucoses, and celluloses. They collected dominantly from human daily foods, so that it need for using other materials beside human daily foods such as waste or toxic materials ingredient from plants. Mendioca sao pedro petro or cassava genderuwo was toxic cassava contained highly starch and potentially used in bioethanol ingredient. Indonesia also had potential waste of food likes bananas skins, microalgae, vegetable and fruits traditional market, and grass which had not exploited yet. Under Separated Enzymatic Hydrolysis and Fermentation (SHF) method those materials had observed.We aimed to overview bioethanol usage as an alternative energy. In our previous research used cassava genderuwo gained, 1L of bioehtanol similar with 3L of kerosene in ratio that used in stove.
