Abstract

Abstract. Soursop leaf (Annona muricata L) is used as a biostabilizer because it contains phenolic compounds in the form of alkaloids, flavonoid tannins, saponins, steroids and triterpenoids. This research focuses on the synthesis and characterization of ZnO nanoparticles using ZnSO4 and soursop leaf extract as biostabilizer. The purpose of this study was to determine the potential of soursop leaf (Annona muricata L) as a biostabilizer for the synthesis and characterization of ZnO nanoparticles using the green synthesis method. The method used is by incubating at a temperature of 300C between soursop leaf extract and ZnSO4 so that nanoparticle deposits are formed. ZnO nanoparticle characterization using FTIR, XRD, SEM-EDX. The results of FTIR characterization showed that there were three stretches of ZnO, namely (421-476 cm-1), (648-673 cm-1), (829-835 cm-1). Results Based on the XRD characterization, the value of 2&#952- showed the peak of ZnO crystallinity while the SEM test showed nanoparticle sizes of 84.74nm, 86.52nm, 88.07nm and 89.88nm, while the results of EDX characterization contained impurities other than Zn and O elements but with a small percentage.
