Abstract

Eucheuma cottoniiwaste seaweed has high cellulose content. Therefore, it could be potentially used as a rawmaterial for biodegradablefilms to replace plastic. A plasticfilm is its moisture resistance, and this propertyallows plasticfilms to be used as packaging materials and biodegraded by microbes. This research aims to obtain aconcentration of glycerol and Carboxy Methyl Cellulose (CMC) to obtain the best biodegradablefilm character-istics fromE. cottoniiseaweed waste. This study was conducted in factorial by using a complete randomized blockdesign with two factors: glycerol concentration and CMC concentration. Each treatment has three levels and threereplications (3�3). Thefirst factor was glycerol concentration: 0.25% (G1), 0.5% (G2), and 0.75% (G3). Thesecond factor included concentrations of 1% CMC (C1), 2% CMC (C2), and 3% CMC (C3). Then, Tensile Strength(TS), thickness, solubility, and elongation were observed. Functional group analysis was conducted by Fourier-transform infrared spectroscopy and biodegradability test. The results showed that the addition of glycerolconcentrations of 0.5 and 0.7% and CMC from 1 to 3% produced tensile strengths of 23–39 MPa. These values areproportional to the tensile strength of Poly Tetra Fluoro ethyne (PTFE) and Poly Propylene (PP) synthetic plasticsreleased by Dotmar Engineering Plastics. The biodegradability test showed that the produced biodegradablefilmsdecomposed after 14 days
