【 摘 要 】

The main objective of this study is to improve mechanical properties of bioplastic film and resistant to bacteria by the addition of percent ratio Zinc Oxide/Organoclay (ZnO/Clay) nanoparticles as enforcement and clove essential oil. All bioplastic film was formed by casting method. The addition of clay nanoparticles in the plastic films was varied from 1:9%, 2:8%, 3:7%, 4:6%, and 5:5% (w/w) by weight of starch. Structural characterization was done by Fourier Transform Infrared Spectroscopy (FTIR). Surface morphologies of the plastic film were examined by scanning electron microscope (SEM). The result showed that the Tensile strength (TS) was improved significantly with the addition of ZnO/Clay nanoparticles. The optimum tensile strength obtained was 20.87 M.Pa on the additional of ZnO/Clay nanoparticles by 0.3:0.7% and plasticizer by 25%. Based on data of FTIR, the produced film plastic does not change the group function and it can be concluded that the interaction in biodegradable plastic produced was only a physical interaction. The biodegradable plastic based on cassava starch-ZnO/Clay nanoparticles and plasticizer glycerin showed that interesting mechanical properties being transparent and clear.
