Abstract:

The study developed a composite plant bag using water hyacinth (Eichornia crassipes) cellulose and mung beans (Vigna radiata) starch, with glycerol as plasticizer, aiming to address environmental concerns associated with petrochemical-based bags. Employing a Completely Randomized Design, the study aimed to determine the optimal cellulose-to-starch ratio based on physical and mechanical properties such as tensile strength, elongation, swelling behavior, and biodegradability. Five treatment groups (four experimental cellulose-starch mixtures and one control (pure starch mixture)) were prepared each replicated four times. Evaluations were conducted using one-way Analysis of Variance (ANOVA) to assess differences among the mixtures. Results indicated that the optimal mixture consisted of 80% base mixture and 20% water hyacinth cellulose, which exhibited superior tensile strength (40 MPa), elongation (40%), swelling percentage (0.9), and biodegradability (4.2) compared to the control. The ANOVA results revealed a statistically significant difference among the treatments (F = 15.24, F crit = 3.24, p = 0.0000597), confirming that the addition of water hyacinth cellulose significantly enhanced the composite's physical and mechanical properties. The study concludes that higher concentrations of water hyacinth cellulose can effectively improve the durability and shelf life of bioplastic plant bags, supporting their potential as an eco-friendly alternative to conventional plastics.
