Abstract
Starch is an abundant natural polymer and we can easily find it anywhere, especially corn starch which is often found in the Madura island. Corn starch is a type of polymer that is renewable, biodegradable, cheap and potential as an alternative material for the manufacture of plastics. Conventional plastics have many problems, namely the difficulty of being decomposed naturally. Therefore, an alternative material that has good biodegradability is needed, such as corn starch. In addition to the use of corn starch which is used as a basic ingredient in the manufacture of biodegradable plastic, cabe jamu extract is also added as an antioxidant. This study aims to determine the biodegradability of biodegradable plastic with corn starch as the matrix and the addition cabe jamu extract as a natural antioxidant. Corn starch-based biodegradable plastic has excellent biodegradability and the addition of cabe jamu helps to increase the antioxidant capacity.
