PENAMBAHAN KONSENTRASI ASAM LEMAK BEBAS MINYAK JELANTAH TERHADAP KARAKTERISTIK ETANOL SEMI PADAT
Abstract: This research was
aimed to obtain a concentration of free fatty acid of waste-cooking oil that
obtained the best semi-solid ethanol. This research used the completely random
design with 5 treatments with 3 times repetitions for each treatment. Data were
analyzed using ANOVA, when F count is greater or equal to F the table then
continued by DNMRT at 5% level. The results of this research shows that the
addition of various concentrations of free fatty acid significantly affected
the real effect (P<0.05) to combustion residue, heat caloric value, heat
transfer, and the degree of acidity (pH). The best formulation was the
treatment A2 (free fatty acid concentration of 5%) having a viscosity of 16,797
cP, the heat caloric value 23.029 J/g and combustion residue 39,26%.
