Abstract
Plastic waste in Indonesia in 2020 reached around 5.66 million tons, or 17.1% of the country's total waste based on Data from the Ministry of Environment and Forestry of the Republic of Indonesia (2020). Using bio-plastics is one solution to this problem. Bioplastics are plastics made from biodegradable materials such as cellulose. Durian rind contains high levels of cellulose (50 - 60%) and lignin (5%). Durian rind cellulose can be ex-tracted through delignification. Phase inversion is a process in which a polymer is changed in a controlled manner from a liquid to a solid state. Phase inversion method is used to make bioplastics from durian rind cellu-lose with the addition of chitosan and glycerol to test for the effect in me-chanical test properties of bioplastic (tensile strength, elongation, swelling and biodegradation tests). Bioplastics are made with variations chitosan levels of 8%, 10%, 12%, 14% and 16% and variations glycerol levels of 1%, 2%, 3%, 4%, 5%. The best bioplastic from durian rind cellulose is the variation of 16% chitosan and 1% glycerol. The bioplastic has a tensile strength value of 1.1603 Mpa, biodegradation of 98.99% in 12 days and swelling (water absorption capacity) of 25.11% and elongation of 12.20. %. Keywords: bioplastic, cellulose, durian rind, phase inversion
