MetadataShow full item record
This study aimed to compare adsorption capacityof solid waste of agar and its carbonization results for indygosol dyes and to compare coagulation-flocculation using adsorpstion process to reduce batik industry waste dyes. The waste after treatment by netralization and coagulation-flocculation using alum reduced chemical oxygen demand (COD) and dyes percent by 45 % and 57.78 % at 50 and 150 ppm alum. Solid waste of agar contained 69.68 % crude fiber which indicates high carbon content in the sample. Solid waste of agar after carbonization had adsorption capacity and efficiency of 6.2394 mg/g and 83.38% for indigosol dyes, and could reduce dyes and COD in the batik industrial waste decreased by 59.81% and 22.19%. Solid waste of agar without carbonization resulted adsorption capacity and efficiency of 3.0644 mg/g and 40.87% for indygosol dyes, and could reduced dyes and COD of the waste by 52.78% and 18.13%.
