ABSTRACT. Plastic causes environmental pollution because it is difficult to decompose in nature. The large amount of bagasse in Indonesia and the high cellulose content can be used as filler for making bioplastics. Cellulose as a bioplastic filler provides water resistance, inhibits biodegradation, and increases tensile strength. Therefore, research was conducted using bagasse as a bioplastic filler. Bioplastics are made by the solution casting method. The best results of water absorption at the ratio of starch: bagasse 7.5:2.5; mass of sorbitol 2,3 g; and temperature of 75oC with a value of 46.638%. The best results of biodegradability at the ratio of starch: bagasse 8.5:1.5; mass of sorbitol 2,7 g; and temperature of 65oC with a value of 88.253%. The best results of tensile strength and elongation at break are 2.9574 N/mm2 and 0.8896%. The results of the both tests still do not meet the requirements of SNI 7818:2014 standard.
