Soursop leaf (Annona muricata L) is used as a bio stabilizer because it contains phenolic compounds in the form of alkaloids, flavonoid tannins, saponins, steroids, and triterpenoids. This research focuses on synthesizing and characterizing ZnO nanoparticles using ZnSO4 and soursop leaf extract as a bio stabilizer. This study aimed to determine the potential of soursop leaf (Annona muricata L.) as a bio stabilizer for the synthesis and characterization of ZnO nanoparticles using the green synthesis method. We incubated soursop leaf extract and ZnSO4 at a temperature of 300 °C so that nanoparticle deposits formed. ZnO nanoparticle characterization was carried out using FTIR, XRD, and SEM-EDX. The results of FTIR characterization showed three stretches of ZnO at (421-476 cm-1), (648-673 cm-1), and (829-835 cm-1). Based on the XRD characterization, the value of 2θ showed the peak of ZnO crystallinity, while the SEM test showed nanoparticle sizes of 84.74 nm, 86.52 nm, 88.07 nm, and 89.88 nm. In contrast, the results of EDX characterization suggested impurities other than Zn and O elements but with a small percentage. © 2025 American Institute of Physics Inc.. All rights reserved.
