Abstract
Waste seaweed is one source of raw material for the manufacture of biodegradable films of considerable potential. In the industrial extraction of carrageenan, Eucheuma cottonii used only about 30-35%, and 65-70% to waste tends to be wasted and organic waste. Therefore, efforts to purify the seaweed waste of unwanted compounds such as lignin. This study aims to determine the chemical characteristics resulting from the purification process using NaOH and H2O2. Results showed increased concentrations of NaOH and H2O2 can cause decreased levels of cellulose, hemicellulose and lignin content in pulp fiber waste from seaweed. The best concentration of NaOH is 3% which resulted in 67.75% of cellulose, hemicellulose and lignin 13.1% 6.35% while the concentration of H2O2 best is 3% which produces cellulose of 44.29%, 22.12% hemicellulose and lignin 11%. Keywords: waste seaweed, NaOH, H2O2
