In this initial study, agar/kenaf core fiber (KCF) biocomposite films, with and without dolomite (Dol), were prepared by solution casting. The prepared biocomposite films were cut into a rectangular shape for tensile testing. The tensile test of the biocomposite films was conducted using a universal testing machine. The tensile test results indicated that the incorporation of KCF increased tensile strength at 4 wt.% KCF, while Young’s modulus increased at 12 wt.% KCF. However, elongation at break decreased progressively as KCF content increased. Based on the tensile strength, 4 wt.% KCF was selected for Dol incorporation. Incorporating Dol resulted in the highest tensile strength and Young’s modulus at 4 wt.% Dol, accompanied by decreased elongation at break. Statistical analysis revealed that KCF content significantly affected all tensile properties, whereas Dol content significantly affected all tensile properties except tensile strength. In summary, KCF and Dol incorporation increased the stiffness and tensile performance of agar-based biocomposite films while reducing their extensibility.
