The synthesis of silver nanoparticles by the bioreduction method has been successfully carried out using the meniran (P. niruri) as bioreductor. The synthesis was started by varying the volume of AgNO3 in the ethanol extract of meniran 1:1, 1:2, 1:3, and 1:4, so that the optimal volume was 1:1 based on the results of UV-Visible spectrophotometer analysis with an absorbance of 0.306 at maximum wavelength of 409 nm. Based on the measurement using Zetasizer Nano ZS, the resulting silver nanoparticles has paticle size of 740.4 nm. The FTIR analysis showed that there was an increase in the percentage of transmittance of the hydroxyl group which proved the reduction of Ag+ ions to Ag0 and the formation of silver nanoparticles. The Scanning Electron Microscopy proved that the morphology of silver nanoparticles varies in shape and the surface is smooth due to their tendency to agglomerate.
