Research on the manufacture of bioplastics from bran is one of the efforts to develop the development of environmentally friendly plastics because they can be decomposed by microorganisms. In addition, this study also seeks to reduce environmental pollution due to the disposal of rice mill waste. The research was conducted by mixing rice bran with water, sulfuric acid and sorbitol in various variations of the ratio of sorbitol and bran 1:10; 2:10; 3:10; 4:10 and 5:10 (v:b). Furthermore, chitosan was added as a reinforcement with variations in the addition of chitosan with bran, namely 4:10; 6:10; 8:10; 10:10 and 12:10 then printed and analyzed for dance strength, swelling and surface morphology. The test results showed the highest tensile strength value in the ratio of sorbitol and bran 5:10 and chitosan bran 10:10 with the highest tensile strength value of 64.27 MPa and 25% swelling value. Surface morphology shows an uneven and hollow surface.
