Abstract

Synthesize CMC uses cellulose extracted from cornstalk waste. FTIR and XRD characterize CMC synthesize. Alginate: CMC (AC) beads made by dropping technique through the ionic gelation method with crosslinking CaCl2 3%. Fourier Transform Infra-Red (FTIR) to know the AC’s function group, swelling test to know the swelling power, and SEM-EDX to see the surface characteristics. The optimum composition of AC composite beads was 1:2 based on beads’ formation, the highest swelling power value 175.5%, and the diameter was 26.64%. The data FTIR AC showed that wave number at 819 cm-1 indicates the presence of Ca-alginate linkage. The SEM-EDX of AC without CMC 1:0 showed a smooth surface, while the surfacer character of AC 1:2 is rough
