I. Introduction
Various innovations have been carried out to create environmentally friendly and useful biomass energy for the development of renewable alternative energy so that it can provide a sustainable source of energy. As it is known that biomass energy is a type of fuel created by converting biological materials such as plants, manure from animals and microorganisms. Various examples of biomass energy include: First Biogas, is a type of alternative energy produced through the breakdown of organic materials, such as manure, human waste, plant material and others. How to make biogas is that all the organic material is broken down through the fermentation process using the help of anaerobic microorganisms to produce methane gas and carbon dioxide. Secondly, wood is combusted on the wood producing heat energy released by the wood used to produce heat, cooking and on a large scale wood is also used for electricity production, such as steam power plants. Third, agricultural waste that can be used for this energy is manure, bagasse and also straw. These wastes can be processed into fuel to produce electricity and heat. The four energy plants, including hemp, com, wheat and soybeans. These plants are deliberately planted on a large scale to produce fuel, such as propanol, bio-diesel, butanol and ethanol.
