KONVERSI KULIT PISANG MENJADI GLUKOSA MENGGUNAKAN KATALIS ARANG AKTIF TERSULFONASI
ABSTRACT: This research
engages banana peel as the source of cellulose for hydrolysis into glucose
using sulfonated activated carbon as catalyst. The aims of this research are to
study the effect of hydrolysis temperature, hydrolysis times, and the weight of
catalyst, to conclude the mathematical model plotted from the yield and the
variables, and to conclude The optimum conditions for hydrolysis of banana peel
cellulose into glucose which includes hydrolysis temperature, hydrolysis times,
and the weight of catalyst.
This research is designed into two
steps, the sulfonation of the activated carbon and the hydrolysis of banana
peel cellulose. H2SO4 10 N is used for the sulfonation which is done in 6 hours
at 40oC. After the catalysts are dried and calcinated, the catalysts are ready
for the hydrolysis precesses which are done in the autoclave batch reactor.
After that, spectrophotometer is used to analyze the sample. The results was plotted
on a mathematical model and then optimized using the software Statistica 6.0 by
Response Surface Methodology method (RSM).
The result obtained by a mathematical model for relationship activator
combination temperature, time and weight of catalyst for content glucose Y =
3,035+0,18 x1 + 0,04 x1² + 0,089 x2 + 0,012 x2² +0,047x3 – 0,021 x3² – 0,014
x1x2 – 0,087 x1x3 + 0,022 x2x3. The optimum conditions of hydrolysis variable
for glucose obtained by statistica 6.0 software which the graph fitted response
surface and contour plot indicates the optimum hydrolysis temperature is in the
range 112°C to 115°C, the optimum hydrolysis time is in the range 300 minutes
to 500 minutes, and the optimum weight of catalyst is about 30 gr which the
sample contains 3,6 mg/ml of glucose.
