Abstract

Manufacturing of biodegradable plastic has been conducted by blending polypropylene plastic waste and durian seed starch. Polypropylene plastic waste was refluxed by xylene solvent and durian seeds starch was prepared by precipitation method with hard water and aquadest. The composition of blends were 94:6, 92:8, and 90:10 (%w/w). The mechanical and thermal properties of the resulting plastics were characterized. Based on the test result, biodegradable plastics with the ratio of 94:6 met the expectation. The mechanical properties obtained were tensile strength of 25.722 N/m2 and elongation at break of 5.292%. Thermal properties analysis showed that the melting point temperature was 163.68°C and the decomposition temperature was 445.62oC.
