Application of Modified Starch on Carrageenan-Based Bioplastic’s Cup From Eucheuma cottonii on Biodegradability and Water Resistance

Polysaccharides from carrageenan have potential as bioplastics that is resistance to waters (hydrophobic), alsocan be improved by using modified starch. Modified starch a material can reduce the hydrophilic properties of bioplastics. The objectives this study were determine effect application on carrageenan-based bioplastic’s cup biodegradability and water best bioplastic formulation for resistance. This was conducted experimental methods in biodegradation test or swelling test. method used completely randomized design (CRD) at significance level 5% (α = 0.05). results indicate addition high increase but will result slower biodegradability.
