Bioethanol Producing Equipment Prototype Using Cassava Peel Using Microcontroller-Based Destilation Principles

Abstract

Bioethanol is a biochemical liquid in the process of fermentation of sugars from carbohydrate sources using the help of microorganisms followed by the distillation process. Bioethanol can be used as a substitute for fuel oil depending on its purity. Bioethanol with 95-99% content can be used as premium substitution (gasoline), while 40% content is used as a substitute for kerosene. Cassava peel obtained from cassava plant products (Manihot esculenta Cranz or Manihot utilissima Pohl) is the main food waste in developing countries. Each kilogram of cassava can usually produce 15-20% of tuber skin. The cassava skin starch content is quite high, allowing it to be used as a source of bioethanol feedstock. In this research, the distillation process to produce bioethanol is carried out by controlling the temperature and pressure in the distillator so that the bioethanol produced can be maintained.
