Exploring Gnetum Gnemon L. Fibers In Noken Bag: A Path to Sustainable Material Development Through Mechanical Testing

Abstract This research investigates the mechanical properties of Gnetum gnemon L. fibers, a traditional material used in Papua’s UNESCO-recognized Noken bags. The study examined three different weaving patterns (1×1, 2×1, and 2×2) to determine their tensile strength and elongation characteristics. Testing revealed that the 2×2 weave pattern demonstrated the highest tensile strength with a mean breaking force of 678.09 N, while the 1×1 pattern showed the greatest elongation at break at 195.37%. Compared to other natural fibers like pineapple, yucca, coir, cotton, and bamboo, Gnetum gnemon fibers exhibited superior mechanical properties with a tensile strength of 739 N and density of 1.72 g/cm³. These findings suggest significant potential applications in technical textiles, protective clothing, and composite materials. The study highlights the untapped potential of Gnetum gnemon fibers, particularly in Papua where the species is abundant yet underutilized. Further research on durability, environmental resistance, and industrial-scale performance would be valuable for developing practical applications of this promising natural fiber.
