House Gas Emissions, and utilize indigenous renewable and sustainably-sourced clean energy sources (Dematelis, 2 Ethanol nas g characteristics. example, it is safer to use than diesel or gasoline and emits less greenhouse gases. For us to meet the demand, many studies are being conducted regarding ethanol production. Various plants such as cassava peels, banana peels, mango peels and other fruits are being used to produce ethanol. These plants used for ethanol production contain a large amount of sugar or components that can be converted into sugar, such as starch or cellulose (West, n. d. ).

Gabing San Fernando (Xanthosoma sagittifolium) is not native to the Philippines. Some reports said that it originated in the Jungles of southern Central America, other South American nations and spread quickly throughout most of the Caribbean. These starchy tubers grow underground and can become very large. They are used as a component of feed for pigs here in the Philippines, but a primary source of carbohydrate throughout the Caribbean and Latin countries (Exotic Rainforest, n.

d. ). Significance of the Study We are going to do the study for us to produce ethanol from plants or crops that re not well-known.

The substrate that we are going to use is the gabing San Fernando (Xanthosoma sagittifolium) or locally known as “sakwa” because they are good source of starch, which is one of the components for ethanol production. The tubers are rarely used as a food source for people as well as animals. Ethanol is used as a fuel additive to gasoline or diesel in the implementation of the Biofuels Act of 2006. Bioethanol is used because of its good characteristics that help in the protection of the environment and health of the people. Some good characteristics of ioethanol is that it has lower flammability and vapor pressure than other diesel or gasoline.

Another good characteristic of bioethanol is that they are obtained from crops, wastes and others which we can produce domestically. It also emits less pollution that helps in the prevention of global warming. Scope and Limitation The study will involve the use of gabing San Fernando tubers which will be tested for ethanol content using analytical/wet method of alcohol extraction. The study will be limited to laboratory techniques of alcohol extraction like saccharification and fermentation. The ethanol content and amount of sugars under arying temperature, water content, and type of chemical used for hydrolysis will be measured.
