Extract of epiphytic shrub leaves ( Ficus heteropleura Blume) serves as a bioreductant in producing silver nanoparticles, which are utilized for their antibacterial properties against Escherichia coli . This study aims to synthesize silver nanoparticles and assess their activity against Escherichia coli . Silver nanoparticles (AgNPs) were synthesized using the green synthesis method with Ficus heteropleura leaf extract with silver nitrate (AgNO 3 ). AgNPs were synthesized using a 1 mM solution of AgNO 3 and different concentrations (2, 4, 6, 8, and 10%) of Ficus heteropleura extract. The AgNPs were characterized using UV-Vis spectrophotometer, FTIR, and PSA. UV-Vis analysis revealed that AgNPs at concentrations ranging from 2% to 10% exhibited absorbance peaks within the wavelength range of 201.2–473.5 nm. FTIR analysis identified functional groups such as OH, CH, C=C, C≡C, C≡N, and CO, which played a role in reducing silver nanoparticles. The size distribution of AgNPs was determined, with AgNPs synthesized at a concentration of 6% exhibiting a size range of 1–100 nm, constituting 40.77% of the total. For AgNPs synthesized at concentrations of 8% and 10%, the percentage of nanoparticles in the 1–100 nm size range was found to be 26.845% and 1.28%, respectively. The antibacterial activity of AgNPs at concentrations of 6% and 8% against Escherichia coli demonstrated moderate effectiveness.}, issn = {2597-9914}, pages = {101--109} doi = {10.14710/jksa.27.3.101-109}, url = {https://ejournal.undip.ac.id/index.php/ksa/article/view/59081} }
