Silver nanoparticles have various applications, such as antibacterial, antidiabetic, anticancer, pesticide waste decomposer, and catalyst. The synthesis of silver nanoparticles in this study was carried out using an extract of jambu hutan leaves (S. pyrifolium) as a bioreductor to reduce 40 mL of a 1 mM AgNO₃ solution, with variations in extract volume at 3 mL, 5 mL, and 7 mL, and variations …
