Abstract

This study was conducted to produce a biodegradable plastic film from the Dioscorea Hispida Dennst korot tuber extract. Specifically, it aimed to determine the physical properties of prepared plastic film from korot extract in terms of effect of strong acid and base, flammability, pH, transparency, tensile strength and texture. It also aimed to determine the mechanical properties of prepared plastic film from “korot” extract and determine the permeability in water of the plastic film. The test for effect on strong acid and base in the two formulations showed that the plastic films were both soluble in strong acid and base. The film was flammable with luminous flame, with pH of 6.3. The produced film was smooth and transparent. The tensile strength test for formulation B was more stretchable and stronger than formulation A, and the weight resistance of formulation B was 1.2 kg while 0.8 kg for formulation A which is comparable to commercial plastic film. The two formulations differ in texture for which the formulation A was smooth and thinner than formulation B which was slightly rough. The produced plastic film was permeable in water. The prepared film was incomparable to commercial plastic wrap, for the prepared film water lost was 4.0 mL to 6.0 mL higher than 1.4 mL for commercial plastic film. The researcher found out that “korot” tuber can be used as main raw material in preparing commercial plastic and the formulation A is better than formulation B. by Franz Joy A. Caballa | Melinda C.
