One way to overcome the problem of non-renewable plastic raw materials and hard-to-degrade plastic waste is to make plastics that are easily degraded and use renewable raw materials. This research makes bioplastics from oil palm empty fruit bunches (OPEFB), cassava peel starch, oleic acid plasticizer, and Carboxymethyl Cellulose (CMC). In the manufacturing process, OPEFB is extracted to produce cellulose. Then, the starch and cellulose acetate solutions and CMC were mixed with stirring for 15 minutes and then 1 mL of oleic acid was added at a temperature of 70-80oC. Next, the bioplastic solution was molded and heated in an oven at 60°C for 6 hours. Variations in the composition of CMC by 35%, 40% and 45%. The results of this study obtained the highest water absorption value at 40% CMC variation of 88.89%. The highest biodegradation test value was at 40% CMC variation of 70.48%. Whereas for the highest tensile strength value in the 35% CMC composition variation of 2,133 MPa. For the highest elongation at 40% CMC variation of 2.212%. Thus, the more CMC composition used, the easier it is for bioplastics to be degraded.
