Chemical treatment is a standard method to improve natural fiber properties. Treatment using a chemical agent like Silane as Coupling Agent and CTAB (Cetyl Trimethyl Ammonium Bromide) as a surfactant can improve the natural fiber properties. The current study aims to observe the fiber surface morphology and obtain the mechanical properties of Sansevieria cylindrica fiber after being treated with a silane coupling agent and surfactant CTAB. The research was conducted by chemical treatment using Silane 5.0% and CTAB 5.0% on S.cylindrica fiber extracted from about a year and lengths up to 110 cm. The tensile test was performed using a single fiber tensile test, and the surface morphology was observed under Scanning Electron Microscopy (SEM). The results indicate that adding 5.0% silane coupling agent results in fiber strength of 281.5 MPa, elongation of 8.92%, and elastic modulus of 3.37 GPa. The addition of CTAB of 5.0% results in fiber strength of 237.4 MPa, elongation of 8.92%, and elastic modulus of 3.37 GPa. Increasing these properties has resulted from the bonding forming of silanols with hydroxyl groups of fiber. The morphology of the fiber surface shows a rough surface caused by removing impurities over the surface for the treatment of both coupling agents and CTAB. © 2024 American Institute of Physics Inc..
