Pengaruh Penambahan Graphene Oxide Terhadap Sifat Mekanis Bioplastik Berbasis Pati Sagu

---

Bioplastics are an alternative for conventional plastics that are biodegradable because its made from natural materials that can be decomposed by the environment. Bioplastics can be made from sago starch and filler wich is graphene oxide because its availability and it can improve the mechanical properties of bioplastics. This study aims to make bioplastic from sago starch with the addition of graphene oxide, while study the effect of adding graphene oxide and stirring time to the resulting bioplastic mechanical properties. Bioplastic preparation was performed by using intercalation method of the solution, while the graphene oxide was synthesized using Hummers modification method and produced dispersed of graphene oxide in the solution. The analyzes were graphene oxide crystallization test, mechanical properties test (tensile strength, elongation and modulus young), morphological test, functional group qualitative test of bioplastic composite and graphene oxide, bioplastic biodegrability and hydrophobicity. The result of bioplastic tensile strength analysis showed that the addition of graphene oxide and stirring time influenced the bioplastic mechanical properties where the highest tensile strength was 4.018 Mpa for 15% graphene oxide with 50 minute and bioplastic can be naturally degraded 70-80% within 8 days with the highest hydrophobicity of 88.7%. Analysis of bioplastic micrographs showed that bioplastics with 50 minutes mixing time had distributed the filler evenly.
Keywords: bioplastic, graphene oxide, hummers, solution intercalation, sago starch.
