The second-hand drum

As being untangled beforehand, biogas could be made from the remnants, the outcast or the waste.
It was important that the remnants and this outcast had the shape of the organic compound, like that came from the crop or the animal.
The material that could be used to make the basin, the implement or the manufacturer's vessel and the cross-section biogas, also might not from the expensive material or was difficult to be obtained by him.
The second-hand drum of the origin was still strong, was the most general material was utilised.
Biogas was gas that was not coloured, did not smell and very high and fast his flame power.
Because of this from biogas was to his manufacturer's vessel to was used for information or cooked, always must be avoided by his presence from fire that could cause fire or the explosion.
This was connected with the possibility of the occurrence of baldness to equipment that was not known.
Made biogas not only depended on the material that was utilised, to the implement or the vessel that was used, but also still had other factors that were with him, that was direct or indirectly will be influential towards results.
For example we have put materials that were needed in the manufacturer's vessel that was accompanied with the starter that was needed.
But evidently several days afterwards, the vessel of the results cross-section did not increase.
If this happened had two possibilities of his cause.
It was first that the vessel of the results cross-section leaked, through to as soon as possible must be looked for and mended or the process of the production biogas did not go.
The manufacturer's material biogas was the organic matter contained high nitrogen.
While the process of the production of compost that will go out and was used was C elements, H, and 0 in the form of CH4 and CO2.
Because of this available nitrogen will continue to remain in material, in the future to the source of organic fertiliser.

The Use

Biogas like also other gas that already the public was used as energy, could be used for many interests, especially for the interests of information and cooked.
His problem now because of light or the stove that has been general and normal is utilised for other gas apart from biogas was not suitable for the use biogas, beforehand needed the change or the certain adjustment before.
This was linked because of the form and the characteristics biogas was different from the form and the characteristics of other gas that has been general.
The centre of Pembangunan Technology (PTP) ITB for example, since long before made light or the stove that could use biogas, that from him from light petromak or the available stove.
The change and the adjustment from light petromak or the normal gas stove that could use biogas was based on consideration of the safety and the use.

Like for example the characteristics biogas that was not coloured, did not smell and very fast was on.
It was because of this that light or the stove had baldness, will be difficult to be known as soon as possible.
Was different from the characteristics of other gas, a case gas-city or lpg, then because of smelling would fast could be known if baldness to the implement that was used happening.
Sifat fast was on biogas, also was the special problem.
Meaning that from the aspect of the safety of the user.
So as the place of the production or the reception biogas always must be far from the source of fire that the possibility could cause the explosion if his pressure was big.
Kompor biogas that was compiled and diujicoba PTP ITB was compiled from the framework, the arsonist, spuyer, the ring penjepit spuyer and the organiser's ring of air, that if being arranged will have the specification of the temperature of the flame could reach 560�C with the colour of the blue flame young tonight, and the rate of the use biogas 350 litre/the hour, as well as his price was estimated between Rp 2,500.00 and Rp.
3,000.00 (the note in 1978).

While light biogas that also was changed and diujicoba from light petromak that consisted of the pipe pole and the organiser's valve of the needle spuyer, the pipe pole and nosel spuyer, the pipe and air of the gas mixer, the nut penjepit the reflector, the arsonist's space, socks, the chimney (protective glasses had the shape of the cylinder) and the reflector, evidently had the price between Rp 4,500.00 and Rp 6,000.00 (in 1973).
For more information to them who needed information was more detailed
about the stove and light biogas this, better be connected with the Centre of Pembangunan ITB Technology, JIn.Ganesa 10, Bandung.

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. 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. 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. 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. 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. 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.

Reaped Biogas from Limbah

BIOGAS or gas bio was one of the energy kinds that could be made from many waste matter kinds and the remnants material, a kind of waste, the waste of the livestock, straw, eceng the goitre as well as many materials again other.
In short, all the material kinds that in the chemical term including the organic compound, whether came from the remnants and the waste of the animal or crop, could be made the material biogas.

The production and the use biogas as energy as being proper for energy from firewood, kerosene, gas, et cetera has been known since long before, especially in the farmer's English circle, Russia and the United States.
Whereas in the Asian Continent, was recorded by the Indian country since still was colonised by England as the pioneer and the user of energy biogas that was very wide, in fact has been united with the normal TOILET.

In Indonesia, the production and the use biogas began to be stimulated at the beginning of the 1970 's, especially because of aiming at making use of the outcast or the remnants who were abundant from the object that was not useful to that was useful, as well as looked for the source of other energy outside firewood and kerosene.
Was based on materials to make biogas, the method and the environment of producing him, in fact biogas could be produced anywhere.

The production biogas could in the form of that was simple (for the interests of the limited household) or in the form of that was or big (for the interests with several houses or more).
Also was related to the place or the vessel to make him.
Simply from the second-hand drum that still was strong or deliberate was made in the form of the vessel from the wall or other materials.

To just gave the picture, along with this will be untangled several notes that were connected with the production and the use biogas that could be carried out in the rural environment, good autonomously (the individual) or together with the neighbour, in fact in the form of efforts even.
