The research efforts of Nanoparticles (NPs) with photocatalytic and antibacterial characteristics have attracted the attention of researchers including synthetic inorganic and organic nanoparticles. Synthesis and characterization of zincphosphate have been carried out using ammonium dihydrogen phosphate as a precursor, red dragon fruit peel extract (Hylocereus polyrhyzuz) as a sensitizing agent and antimicrobial activity tests of these materials. This study aims to obtain a photocatalytic material Zinc Phosphate (Zn3(PO4)2) and to determine the antibacterial activity of the Red Dragon Fruit Peel extract Zn3(PO4)2. Zn3(PO4)2 can be photocatalytically increased in the visible range through preparation by adding a sensitizing agent to the skin of the Red Dragon Fruit (Hylocereus polyrhyzuz) plant extract. This success is proven by visualization and characterization using Fourier Transform Infra Red (FTIR) and Ultra Violet-Visible (UV-Vis) Spectrometers. The photocatalytic properties of a material can be determined from the particle size and energy gap. FTIR analysis showed the presence of OH, C = O, CO and aromatic rings, as well as the presence of O = PO and P-O-P groups. The results of UV-Vis analysis showed that the absorbance values for 30 minutes tended to be stable. The results of UV-Vis spectra characterization showed that Zinc Phosphate nanoparticles had a higher band gap energy value as the volume of Zinc Phosphate increased. The antibacterial activity test showed that the red dragon fruit peel extract incorporated in Zinc Phosphate had moderate inhibition against Staphylococcus aureus and weak against Pseudomonas aeruginosa.
