Pengaruh Variasi Fraksi Volume Mikroselulosa Serat Daun Nanas (Ananas Comosus) Sebagai Reinforcement Pada Bioplastik Polylactic Acid (PLA)

Countermeasures conventional plastic waste which does not naturally decompose faces various environmental problems, such as environmental pollution, and sources disease, so needed alternative material plastic environmental friendly (biodegradable) and easily decompose naturally. One of material biodegradable materials was obtained from starch plants and pineapple leaf fiber cellulose. This research focuses on influence variation volume fraction microcellulose of pineapple leaves fiber on polylactic acid (PLA). In research it was varied ratio volume fraction of PLA to microcellulose, namely (100:0; 98:2; 96:4; and 94:6%vol). Phase inversion method used for manufacturing PLA bioplastic, with pineapple leaf fiber isolated as cellulose through alkali treatment (NaOH 0,5 M) and belaching (H2O2 3%). Pineapple leaf fibers were tested for cellulose and x-ray diffraction (XRD). The resulting bioplastics were tested for tensile strength, water absorption and natural degradation ability. Cellulose and XRD test result pineapple leaf fiber after treatment bleaching obtained of 72.45% with index crystallinity 73.48%. Bioplastic test results obtained tensile strength 6,41-4,91 MPa, elongation 52,7-19,24%, Young's Modulus 295-149,5 MPa, water absorption 0.44-3.12%, and ability to degradation with a percentage of mass loss 3.48-13.64% and degradability 0.35-1.36%/day. Research result show that increasing variations of microcellulose volume fraction decreases the mechanical properties of PLA bioplastic but enhances water absorption and natural degradation. This is caused by uneven cellulose distribution supporting agglomeration, hindering the penetration of PLA matrix into cellulose, and indicating the low compatibility between cellulose and PLA matrix.
