Test of active carbon adsorption from Cassava (Manihot utilissima) peels against dyes

Cassava peel is the leading waste generated by the cassava processing industry. One of the regulatory efforts is to use it as a raw material for activated Carbon to adsorb dyes. This study aims to determine the adsorption capacity of activated Carbon from cassava peel waste on yellow dye. Activated Carbon from cassava peel has been identified using FTIR. The results of FTIR characterization determined the absorption of functional groups O-H, C=C, C-H, and C-O, which indicated the presence of lignocellulose and hemicellulose content in the activated Carbon of cassava peel. The optimum mass measured in this study was 1 g with an adsorption percentage of 59.474%. The optimum contact time measured in this study was 60 min, with a percentage of adsorption power of 82.526%. The optimum concentration of yellow dye measured in this study was 200 ppm with an adsorption percentage of 94.000%
