PEMBUATAN GEL ETANOL DENGAN MENGGUNAKAN BAHAN PENGENTAL Carboxymethycellulose (CMC)
Abstract: The purpose of this
study is to obtain a concentration of carboxymethylcellulose (CMC) as a thickener
and the appropriate concentration of ethanol in the gel formulation of ethanol
as a fuel. This study was conducted experimentally by using completely
randomized design (CRD) factorial. The first factor is the concentration of
ethanol (70, 80 and 90%) and the second factor is the concentration of CMC
(1,2, 1,5 and 1,8 grams). Results of
analysis of variance showed interactions addition of ethanol concentration and
concentration CMC significantly affect ethanol combustion residues gel. The
addition of different concentrations of ethanol significant effect on the
calorific value. The addition of different concentrations of CMC significant
effect on viscosity. The heat is transferred to boil ethanol gel 100 ml of
water is as much as 14,10 grams. At the beginning of the combustion flame color
blue, then turn blue yellow, then yellow bluish color fire to be extinguished.
The best formulations according to the characteristics of ethanol semi-solid
gel that treatment E3C3 having a viscosity of 17434 cP, combustion residues
29,44%, calorific value of 11.751 J /gr.
