Indonesia was ranked as the 2nd country in the world in 2015 with the most plastic waste disposal from the land to the ocean. The government has made many efforts to reduce the amount of plastic on the market and try to divert the use of food packaging from non-plastic materials. One effort that can be done is the use of bioplastics where this material is easily degraded by nature. This experiment uses avocado seeds as based material of bioplastic, sorbitol, and glycerol are mixed with the melt intercalation method and ZnO powder is added 1%, 2%, 3%, 4%, 5%, and 6% to strengthen the mechanical properties of bioplastics. Tensile test results show that the addition of ZnO 1% to 3% can increase the tensile strength of bioplastics while the addition of 4-6% reduces the tensile strength up to 39%. Storage at room temperature for up to 3 weeks shows increased tensile strength values but shows signs of damage to the 4th week. Water absorption data obtained that the highest water absorption is in bioplastic samples without ZnO content with value 86% and the smallest water absorption is at 6% ZnO content of 40%.
