Synthesis of Imine derivates used as antibacterial activity has been done. Synthesis was conducted by condensation reaction between piperonal and aniline. The product synthesis was characterized by melting point, LC-MS, FTIR and 1H-NMR, then application of the product as antibacterial towards bacteria Staphylococcus aureus and Escherichia coli. The product of synthesis was pale-brown solid, and had melting point at 56-61 0C. Identification by LC-MS showed the compound molecular weight was 225.30 gram/mol, identification by FTIR showed a compound contained imine C=N at 1620.21 cm-1, C-H aromatic at 1581.63 cm-1, Csp3-H at 2962.37 cm-1 from CH2, and C-O at 1265.30 cm-1, Identification by 1H-NMR showed a compound had a singlet peak at δ=6 ppm that proton was from the CH2, multiplet peak at δ=6.9-7.7 ppm proton from two aromatics and singlet peak at δ=8.4 ppm from proton imine. The minimum inhibitory concentration of the product towards Staphylococcus aureus and Escherichia coli was 1 mg/mL with diameter inhibition zone 2 mm and 3 mm. From these data it could be concluded that the compound 3,4- methlenedioxybenzilyimine was formed and it had ability as an antibacterial agent.
