This study aims to prepare ZnO particles using extracts of Sargassum sp as an anti-bacterial material on woven fabrics. Sargassum sp. powder. mixed with distilled water (1:4 w/v) then heated in the microwave for 1 minute. The extract obtained was added to a solution of Zn(CH3COO)2 as a precursor then heated in a microwave for 5 minutes, and ZnO particles were obtained. The particle size distribution of the synthesis results in an average particle diameter of 240.7 nm. Based on NIR spectra, ZnO-deposited woven fabrics have higher absorbance spectra than unmodified woven fabrics. The peaks that appear on the XRD diffractogram indicate the presence of peaks of ZnO embedded in the woven fabric. Surface morphology analysis using SEM showed the presence of ZnO on the fabric surface. The antibacterial activity test showed that the ZnO-deposited fabric samples gave quite high antibacterial activity against S. aureus and E. coli bacteria. © 2024 Author(s).
