Methane gas

The remnants or the organic compound outcast that came from the crop or the animal will naturally fall apart, good resulting from the influence of the physical environment (like heat of the sun), the chemical environment (like with the existence of the other compound) or that was most general with the existence of the microorganism that was acknowledged as the microbe, good the bacteria or the fungus.

Resulting from the analysis of the organic matter that was done by this microorganism, then will be formed the substance or the other simpler compound (small), as well as once of the him have the shape of CH4 or methane gas.
Methane gas that gathered with CO2 or carbon dioxide gas that afterwards was mentioned biogas with the comparison 65: 35.

As the waste or straw that was processed to compost needed the condition for the certain foundation, likewise in the process of the modification of the waste or the outcast to biogas, needed the certain condition that be related to:

1. 1.The content or the contents that was contained in the material.
   This was related to the value or the comparison between the C element (carbon) and the N element (nitrogen) that generally was known by the name of the ratio of C/N.
   The change in the organic compound from the waste or the waste of the pen to CH4 (methane gas) and CO2 (carbon dioxide gas) needed the condition for the ratio of C/N between 20 - 25.
   So as if using the material only had the shape of straw with ratio-C / N on 65, then although CH4 and CO2 will be formed, the comparison CH4: CO2 = 65: 35 will not be reached.
   Possibly this comparison was worth 45: 55 or 50: 50 or 40: 60 as well as other figures that less than that has been determined, then results biogas him will have the value burnt low or not all that filled the condition as the energy material.
   Also was the reverse if the material that was used had the shape of the waste of the pen, like from the waste of the goat with the ratio of C/N approximately 8, then the production biogas will have the comparison between CH4 and CO2 like 90: 10 or the other too high value.
   With this value then results biogas him was also too high thought bakar him, so as possibly would rnembahayakan the user.
   Another thing that must be paid attention to that is the ratio of C/N too high or too low will influence the process of the formation biogas, because this was the biological process that needed the condition for the certain life, like also humankind
2. 2.The level of material water that was contained in the material that was used, also like the ratio of C/N must exact.
   If results biogas was hoped for in accordance with the current condition, then the material that was used had the shape of the waste of the dry goat was mixt with the remnants of second-hand grass food or with the other material that also dry, then was needed by the increase in water.
   But was different if the material that will be used had the shape of ditch mud that has contained the high organic matter, like from second-hand and reduction in the animal that was mixt with the waste.
   In his material has been contained water, so as the increase in water would not totalling to the dry material.
   Water played a very important role in the biological process of the production biogas.
   Meaning that should not too many (excessive) also should not too few (the lack).
3. 3.The temperature while the process took place, because this was related to the living "happiness" of the processor bacteria biogas between 27� - 28�C. Dengan the temperature the process of the production biogas will go in accordance with the time.
   But was different if the value of the temperature was too low (cold), then time to become biogas will be older.
4. 4.The presence of the processor body, or the body that had the capacity to untangle materials that finally formed CH4 and CO2.
   In the waste of the pen, ditch mud or the waste and straw, as well as other waste matters, many microorganisms, good the bacteria or the fungus pengurai these materials were obtained.
   But that became the problem was results of his analysis not necessarily to CH4 that was hoped for as well as had the capacity as the fuel.
   Then to guarantee so that the presence of the microorganism or the manufacturer's microbe biogas (generally was acknowledged as the methane bacteria), better be used the starter, that is the material or the substrate that inside could have been ascertained contained the appropriate methane microbe that was needed.
5. 5.Aeration or the presence of air (oxygen) for the process.
   In the matter of the production biogas then air in no way was needed in the manufacturer's vessel.
   The existence of air caused gas CH4 will not be formed.
   So then the manufacturer's vessel biogas must in the situation was closed was in a meeting.
   Still had several other conditions that were needed so that results biogas in accordance with the condition.
   But the five conditions have been the condition for the foundation so that the process of the production biogas went as it should be.
