Biogasis the product of fermentation, reshuffle or decomposition of organic materialsincluding human waste and domestic waste (household) and biodegradable wasteprocessed by moranogen bacteria.
Biogas is one of the alternatives ofenvironmental problems lately. Earth’s increasingly aging conditions cause theozone layer is already hollow. This is caused by people who always useunfriendly fuel that can damage the ozone layer. Therefore, biogas is onealternative to environmental problems. This is because biogas is a product ofwaste (organics) products that elaborated by bacteria.
However, it can not bedenied that each product must have some disadvantages, as we can see thatbiogas still has some disadvantages and there is one way to cover theshortcomings of making biogas is to make it in a simple set.However,biogas also has many disadvantages that is it requires high funds for applicationsin the form of biogas installations because biogas can only be produced in thepresence of high technology to produce large-scale biogas products, the labordoes not have adequate capability especially in the production process, thebiogas can not be packed in liquid form in the tube, when the processing takesa relatively long time the material CH4 properties are odorlessmaking it difficult to detect when a leak occurs, flammability, temperatureinfluence on biogas production, biogas production must be in the stabletemperature 37oC to produce it, in biogas product still contains alot of waste and it has an impact when biogas is used to fuel the car it willcause corrosion on the metal part of the machine because the product of biogasstill contains impurities, less suitable for crowded metropolitan areas becauseone of biogas weakness that is biogas can only be produced when there are manyraw materials (waste) to make it. While in the metropolitan area there is nospecific place to unite that waste.Someof the deficiencies of biogas can be tricked in several ways : biogas on alarge scale requires money and high technology to produce it. However, can betricked by the use of one tool for a single household in a traditional way thatuses large drum and assembles them to be used to make biogas products whichtakes 2-3 weeks to be able to use it. in this way we have shed somedisadvantages of biogas.
How to make this simple biogas tool is : If the drumyou buy is covered on both sides then drill one side of the drum with ahacksaw, install Installation of elastic hose (pipe gas), pvc pipe and faucetstop in such a way on the drum-2 bottoms towards the stove. Its purpose is todrain the gas from the reactor drum to the stove, then prepare a solution ofcow dung and water with a ratio of 1: 1 on drum-1. Stir until the solution isevenly mixed.
To speed up the reaction process add a starter of yeast bread,MB3 or others that can be purchased at the store means of agriculture, afterboth drums are ready: drum-1 (drum reactor) containing cow dung solution,drum-2 (gas reservoir) installed pvc pipe installation and elastic hose to thestove, then the next step is to put drum-2 in sink into drum- 1 with the drum-2butt position on top, wait for 2-3 weeks until gas production begins much, withthe marked drum-2 slowly rising upwards as it is filled with gas, if theposition of drum-2 has gone up, means that biogas is already producing and canbe used for cooking purposes every day. To get a higher gas pressure give arock or the other as a weight that is placed on top of drum-2.
