| dc.description.abstract | The use of biomass as an energy source has indeed changed and even begun to disappear from human activities. The availability of fossil energy, especially petroleum, is decreasing over time. Since then, the world has made various efforts to overcome this challenge, but the fact that oil supplies continue to decrease remains a major problem. Therefore, it is very important to develop renewable energy and energy conservation. Renewable energy is a type of energy sourced from nature that can be renewed naturally and will not run out over a long period of time. Bioethanol using empty palm oil bunches is an alternative fuel produced from empty palm fruit bunches as raw material, the production process of which involves the conversion of carbohydrates into sugar or glucose which is later fermented into ethanol.
This research was carried out through an experimental bioethanol production process to obtain high levels of bioethanol using tools, namely a hydrolyzer, fermenter and distillator. This test uses temperature variations in the distillator, namely 70˚C, 80˚C, 90˚C. At a temperature of 70˚C a volume of 463 ml was obtained with an alcohol content of 1%, at a temperature of 80˚C a volume of 680 ml was obtained with an alcohol content of 2% and at a temperature of 90˚C a volume of 972 ml was obtained with an alcohol content of 1%, and for repeated distillation with Three repetitions obtained the first alcohol content of 2%, the second repetition obtained an alcohol content of 15% and the third repetition obtained an alcohol content of 47%. | en_US |
