PEMBUATAN BIOETANOL GEL SEBAGAI BAHAN BAKAR
ALTERNATIF PENGGANTI MINYAK TANAH
Abstract
Bioethanol is an alternative potential fuel because of its source
can be regenerated. However, the use
of bioethanol as fuel to substitute the kerosene is still rare. It is because the plant that
produce
bioethanol still limit and the obstacle when distribute it which
is easy to spill out. Beside that, liquid
bioethanol has high risk to spill out and to explode because of
its volatility property. For solving the
problem, liquid bioethanol will be changed to gelled one. The
objectives of this research are to learn
the influence of water and carbopol to flash point, heat value and
viscosity of gelled bioethanol.
Controlled variables in
this research are bioethanol 90% (weight) ; mixing time an hour and
dependent variables are carbopol 0,85%;1,05%;1,25% (% weight)
and water 7,5%;7,9%;8,3% ( %
weight) .The data will be processed by using Response Surface
Methodology (RSM) so it will gain the result such as the influence of each
variables to the formed bioethanol gell and the optimum operationcondition.
From the research it was found that the flash point was influenced by the percentage of
water and percentage of carbopol; heat value was
influenced by the percentage of water, percentageof carbopol and the interaction within it; viscosity
was influenced by the percentage of
carbopol. Theoptimum value of flash point, 21 0C and the optimum value of heat value, 4000
cal/g was achieved
when the the percentage
of water was 7,9 % and the percentage of carbopol was 1,09 %.
