The Heat Resistant Capabilities of Bioplastic Composites on Sago Hampas Starch-Al2O3

Sago hampas are a waste with high starch content. The from sago can be used as raw material for bioplastics. However, because bioplastics have lower heat resistance than conventional plastics, additives required to increase resistance. Aluminum oxide metal compound that acts an additive Bioplastics were created using weight percentage of 0, 1, 3, and 5% Al2O3. DTA was determine the melting point bioplastics, well their mechanical properties, density, water best results identified FTIR SEM. showed adding Al2O3 at increased points 270, 274, 280 oC. Except obtained oC, tensile strength 3.41 Mpa, elongation 38.66%, density 5.52 g cm-3, 80.28% suitable on Indonesian National Standard 7188.7:2016. analysis revealed containing experienced physical interactions.
