PEMANFAATAN LIMBAH AMPAS TEBU SEBAGAI ADSORBEN UNTUK PENINGKATAN KUALITAS AIR GAMBUT

Abstract

Sugarcane bagasse contains various biomass compounds, like cellulose and lignin,
which has the potential to be converted into a source of carbon for the adsorption process. This study was aimed to use carbonized bagasse powder as an adsorbent to
increase quality of peat water. Bagasse powder was carbonizied at 300 o C for 2,5 hours
and sieved using a sieve storied 100 and 200 mesh. Carbonizied bagasse powder was
characterize in terms of moisture content, ash content, I 2 adsorption capacity, surface
area and functional groups determination using FTIR. Adsorption process was observed
by mass variations (0,5; 1; 1, 5; 2 grams) then at the mass maximum (2 gram) was
continued by contact time variations (30, 60, 90, 120 minutes). Parameters of this study
were analyzed such as odor, colour, pH, turbidity, TDS, TSS, metal content of Fe and
humic acid in peat water. All of the results were compared to PERMENKES RI “About
Requirement and Water Quality Control” No.416/MENKES/PER/IX/1990. The analysis
result showed that variation of contact time does not affect all parameters that have been
analyzed. After compared to PERMENKES RI only odor, turbidity, TDS, content of Fe
(2 grams; 120 minutes) fulfilled the standar, respectively (18,2 NTU; 54,15%),
(98 mg/L; 52,65%), and (0,128 mg/L; 52,65%).
