An alternative wound dressing based on nanofiber mats have been developed recently. The antioxidant and antibacterial activity play an important role in wound healing process. This study aims to combine the properties of  Bassela rubra linn extract  (BRLE) and Alginate from brown macroalgae into Polivynil Pyrrolidone (PVP) nanofiber using electrospinning method. Firstly, the optimization step was conducted to obtain the best operation voltage and distance. Afterwards, the nanofiber composites of PVP/BRLE/Alginate were injected into electrospinning tool in various Alginate concentrations of 1%, 2%, and 3% (w/w) respectively. The morphology of PVP nanofiber observed by Scanning Electron Microscopy (SEM) conveys that the closest distance and the highest voltage were the best. Meanwhile, the in vitro analysis through 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay and antibacterial activity to  S. aureus  and  E. choli  bacteria show a quite strong radical scavenging ability around 60% and adequate antibacterial property as good as reference a well-known material consecutively.
