| Summary: | Ethanol can be produced from renewable sources which called bioethanol and can be used as an<br /><br />
aternative energy. The carbohydrate contents of rice straw can be converted to ethanol by<br /><br />
fermentation. In this research, bioethanol is produced from rice straw liquor which is made by<br /><br />
pressing the fresh rice straw with high pressure. This liquor fermentation was compared to dried<br /><br />
rice straw, those are acid hydrolyzed of dried rice straw and selulase hydrolyzed of dried rice<br /><br />
straw. The amount of sugar in each sampel is determined using Somogyi-Nelson method. In<br /><br />
sample which contain the higest sugar is continued by fermenting it with a commercial yeast<br /><br />
(fermipan) with a variation series of temperatue, pH, and the amount of yeast. |
