SECOND GENERATION BIOETHANOL PRODUCTION
The pretreatment generally refers to thedisruption of the naturally resistant carbo-
hydrate-lignin shield that limits the accessibility
of enzymes to cellulose and hemicellulose (Yan
and Wyman, 2008).
The pretrreatmant can be performed (1)
physically e.g mechanical size reduction, ball
milling, compression milling, high temperatur,
high pressure, (2) chemically e.g using sulphuricacid, HCl, H2O2, ozone, l ime, NaOH, (3)
biologically e.g using white rot fungi, or (4)
combination among the three approaches.

SECOND GENERATION BIOETHANOL PRODUCTION
However, the choice of pretreatmenttechnology is not trivial and must take into
account sugar-release patterns and solid
concentrations for each pretreatment in
conjunction with their compatibility with theoverall process, feedstock, enzymes, and
organisms to be applied.
Therefore, researches to find out the bestpretreatment for certain agro-industrial waste
biomass in Indonesia should be carried out
intensively

COCLUSIO
Since Indonesia has abundant and cheap agro-industrial wastebiomass, productions of the second generation bioethanol from
the biomass are essential in order to overcome our excessive
dependence on petroleum for liquid fuels and also to address the
build-up of greenhouse gases that cause global climate change.
Pretreatment step is the key cost element in the biological
conversion of agro-industrial waste biomass to bioethanol and
must be advanced and carefully integrated with the rest of the
process to realize the full potential of cellulosic ethanol or other
biologically derived products.
It is now time for far more aggressive and intensive to carry out
fundamental and applied researches on the pretreatment step
and its integration with the rest of the second generation
bioethanol process.
