Abstract

The use of conventional plastic affects the environment because it is difficult to decompose thus causing environmental pollution. Therefore, it is necessary to find alternative that origins from degradable materials. Bioplastics are environmentally friendly plastics that can be somposed by the activity of microorganisms. The development of bioplastics from organic materials has been largely done from starchy materials. In this research, bioplastic was made using tapioca starch with sorbitol and glycerol as plasticizers. This research aimed to determine how the influence of temperature and time at heating bioplastic solutions to the quality of bioplastics. Temperature variations used were 63, 65, and 70oC, while the time variations were 20, 25, 30 minutes. The results showed that the best tensile strength at 65oC and 20 minutes treatment was 0.8231 Mpa, the best elongation at 63oC and 25 minutes treatment was 68.75%, the best water absorption at 63oC and 20 minutes treatment was 46.34%, and all samples were degraded 100 % in 18 days. Bioplastics from tapioca starch is very much faster than conventional plastic to be degrade.
