Authors(3) :-Ikhwanuddin, Kurnia Sembiring, Syahrul Humaidi

The bioplastic have been done by using mixture of material : stone banana leaves powder, carboxymethyl cellulosa, and gum arabic through a melt intercalation with variation of composition stone banana leaves powder : carboxymethyl cellulosa : gum arabic 80%:15%:5%, 75%:15%:10%, 70%:15%:15%, 65%:15%:20%, 60%:15%:25%, and 55%:15%:30%wt. The sample fabrication was done in three step. The first step of banana stone leaves is treated using a steam explosive method, then stone banana leaves, carboxymethyl cellulosa, and gum arabic powder sifted with particle of size 100 mesh. Then, powder is mixed until homogenous about 30 minutes with wet mixing method. Second step, the powder was homogenized then it moulded with a glass mould and cooled. Third step, bioplastic sheets has been cold, then compacted to flatten the surface with a mesh of 200 mesh at a pressure of 1 atm held for 20 minutes at 60 °C. The bioplastic sampel were characterized such as : physical properties (density, water absorption, biodegredability and functional groups) and mechanical properties (tensile strength, elongation and modulus of Young). The characterization result show that the optimum composition of stone banana leaves powder : carboxymethyl cellulosa : gum arabic 55%:15%:30%wt had the highest density 1,601 x 103 kg/m3, water absorption 10,247%, and biodegredability 99,2% for 45 days. Mechanical properties with tensile strength 35,71 MPa, elongation break 273,14% and modulus of elasticity 130,378 MPa. Thermal properties with melting point 302.45 oC whose characterization results have fulfilled the standard of SNI 7188.7: 2016. The result of its characterization has fulfilled the standard of SNI 7188.7: 2016. The results of bioplastic based stone banana leaves and CMC composite reinforced gum arabic can can be applied as packaging, and straws.
