Degradable plastic can be used as a substitute for commercial plastic. Degradable plastic made from starch with zinc oxide (ZnO) catalyst and polyvinyl alcohol (PVA) has biodegradable properties. This research used sago starch, breadfruit starch, ZnO catalyst, and PVA as additives to strengthen the mechanical properties of degradable plastic. The research methodology encompassed several stages, including the preparation of sago and breadfruit starch, the synthesis of degradable plastic, and the subsequent evaluation of its characteristics. Various concentrations of ZnO and PVA catalysts (10%, 20%, 30%, and 40%) were employed in this study. Mechanical characteristic test for degradable plastic showed that the tensile strength test for sago starch-based plastic with 40% ZnO catalyst and PVA was 2.31–3.96 MPa, while for breadfruit starch-based degradable plastic was 2.88–3.20 MPa. FTIR analysis revealed that the compound constituents of degradable plastics exhibit hydrophilic properties and readily interact with water, making them susceptible to natural degradation in soil. Furthermore, the thermal characteristics were examined using DSC, which indicated that sago starch-based degradable plastic (with ZnO 40% and PVA 40%) exhibited a thermogram peak at a temperature of 137.15°C, while the breadfruit starch-based plastic displayed a peak at 136.97°C. In terms of water absorption, the swelling index for sago starch-based plastic ranged from 18.35% to 65.26%, whereas for breadfruit starch-based plastic, it ranged from 19.91% to 64.06%. Notably, the lowest water absorption levels were observed at a ZnO concentration of 40% and a PVA concentration of 10%. The higher the PVA concentration, the more water was absorbed due to the hydrophilic nature of PVA, but the higher the ZnO concentration, the lower the water absorption. Degradation of plastics sago and breadfruit starch occurred for 20-28 days and by ASTM D-20.96 (degradable plastics should be decomposed before 180 days). The higher the concentration of ZnO catalyst added to bioplastics, the longer the degradation time, while the higher the PVA content, the faster the degradation time.

Oil palm empty fruit bunches (OPEFB) is one of the palm oil industry solid wastes that can be used as an alternative material to product composites. This research was conducted to determine the effect of the addition of Zinc Oxide (ZnO) as a filler material hybridized with OPEFB fiber to the flexural strength of polymeric foam composites. The aim of this research is to obtain the strength of the flexural test value of the composite material polymeric foam reinforced OPEFB fiber and Zinc Oxide (ZnO) with reference to the ASTM D790-92 standard. The composition of the specimens are 70% Resin, 15% OPEFB Fiber, 15% Polyurethane with different fiber sizes namely mesh (40, 60, 80, 100) and the addition of Zinc Oxide (ZnO) of (0%, 5%, 10%, 15%, 20%). The test specimen used for each composition is 5 samples, so that the entire test sample is 100 samples. From the test data it can be concluded the value of flexural strength in the 100 mesh OPEFB specimens and the addition of Zinc Oxide (ZnO) 10% is the best composition compared to 40, 60 and 80 mesh OPEFB with the addition of Zinc Oxide (ZnO) 5%, 15%, and 20%, where the voltage value is 10,01141 MPa and the strain value is 0,898456 mm / mm. From the research data it can also be concluded that the smaller the OPEFB fiber size with the addition of zinc oxidation (ZnO) 10%, the flexural strength of the polymeric foam composite material will be better.
