Abstract
Bioplastic or degradable plastic is one of convensional plastic alternative which does not endanger for environmental. Making bioplastic can ease the process of plastic degradation inside the ground. Sago can be one of the base materials for bioplastic because it has high starch content. The general aims of this research are to know the effects of adding graphene oxide and stirring time to the mechanical properties (tensile strenght, elongation and modulus young), hidrophobicity, biodegradation and morphology of sago starch bioplastic. Bioplastic was synthesized by intercalation of starch solution, water, filler and plasticizer with combination graphene oxide 0% v/v, 5% v/v, 10% v/v, 15% v/v and combination stirring time 15 and 50 minutes. The results of this research showed that treatment by added of graphene oxide and stirring time contributed to the mechanical properties of bioplastic produced. The best result of bioplastic produced was 10% graph ene oxide and 50 minutes stirring time with value of tensile strenght 4,108 Mpa, elongation 11,528% and modulus young 34,854 Mpa. The result of sago starch bioplastic would degradation 78,9% about 8 days in natural way with value of hidrophobicity 68,571%. Microgaph analysis showed that stirring time affect filler distribution which is bioplastic with stirring time 15 minutes made filler distribution can not spread equally, it can be known by there is still has clots
