Thermal Inversion
Smog surrounds the Angel Monument in Mexico City, Mexico, during a thermal inversion. Air pollution increases dramatically when a mass of cold air is trapped below a mass of warmer air. The absence of air circulation prevents pollution near Earth’s surface from escaping.

Starts from The Problems
Energy Crisis
The use of fossil fuels these days are very closely related to the problem of energy crisis. Fossil fuels are formed and stored materials in the earth that comes from animals and microorganisms were buried millions of years.
Based on these facts, the fossil fuel is a fuel that can not be renewed because it requires a very long process in its formation
Comes with The IdeasBioethanol Bioethanol is one of the
alternative fuels that have advantage than fossil fuel
Why Bioethanol?Bioethanol used plants as the raw material, so it does not make accumulation of carbon in the atmosphere Ethanol can also increase the efficiency of combustion because it contains 35% oxygen and environmental friendly because dump of gas emissions such as carbon monoxide, nitrogen oxides, and other gases are low (19-25%)
How we make it?During this time, bioethanol was produced from molasses (sugar production process waste) or starchy materials (cassava or corn).
But,we face another problem
Cassava, Corn, etc.Source of Food
find other sources of raw materials
containing polysaccharides and not be used as food!
Bagasse!
Meet Bagasse!Bagasse is an industrial solid waste from sugar cane containing cellulose fiber and usually used as a raw material for the paper industry
Bagasse waste not yet widely used. This waste is one of the energy sources potential and generally is a cellulose material that can be converted into ethanol
Sugarcane Planted Area456,700 in (Ha)spread on Sumatra, Java, Kalimantan, and Sulawesi
tons of bagasse can produced100 each hectares in a year
Bagasse in Numbers
National potential of bagasse
4,567,0000tons each hectares in a year

cellulose enzyme and fermenting microbes are added to one vessel or hydrolysis and fermentation happen in one reaction vessel can be done by bacterium Clostridium thermocellum.

Conclusion
Energy Crisis
The use of fossil fuels these days are very closely related to the problem of energy crisis. Fossil fuels are formed and stored materials in the earth that comes from animals and microorganisms were buried millions of years.
Based on these facts, the fossil fuel is a fuel that can not be renewed because it requires a very long process in its formation
• There are two big problems if using the fuel oil continually, the energy crisis and negative effect to environment such as greenhouse effect.
• Therefore, needs a fuels alternative to solve this problem. One of the fuel alternative as substitute fuel oil is bioethanol from sugarcane waste (bagasse). It’s potential because bagasse are abundant, so bioethanol from bagasse can creating new high-paying jobs, increasing market opportunities for farmers, generating additional household income tax and revenues, and simultating capital investment.
• Beside that, using bacteria Clostridium thermocellum can make the process bioethanol production are cheap and fast.
Thank You
Have A Nice Day!
