Sansevieria trifasciata fiber (STF) has a high cellulose content and considerable potential as polymer composite reinforcement. This study aims to investigate the effect of alkali treatment on physicochemical properties, tensile strength, thermal surface characteristics STF. We explored chemical changes in STF that had undergone achieved an optimum increase 51.8 % by weight. Soaking for 120 minutes significantly changed its composition. XRD analysis results indicated crystallinity index size 75 68 nm, respectively. After treatment, density increased 1225 kg/m3, while percentage total weight decreased. Thermogravimetric testing provided relevant data mechanical characteristics, including strength 535 MPa, modulus 4.23 GPa, stability up 371 °C. In addition, modification alkalization wettability matrix, which turn improved ability fibers interact with resin. Observation morphology showed reduction lignin hemicellulose content, properties resulting composite. These indicate optimized be excellent reinforcement composites.
