In this research, curcumin analog of 1-benzil-4-piperidone derivative was synthesized using microwave irradiation with catalyst NaOH. The rendement (YN2) resulted 99.39%. All compounds were characterized using UV spectrophotometer, IR spectrophotometer,1H NMR, and 13C NMR spectrometers. The antibacterial activity was evaluated using the agar diffusion method. Antibacterial activity test was carried out at concentrations of 20, 30, 40, 50 , and 60 mg/disc against Gram positive bacteria (Staphylococcus aureus and Bacillus subtilis) and Gram negative bacteria (Escherichia coli and Salmonella enteritidis). YN2 compounds obtained showed different antibacterial activity against different bacteriaenAntibacterialcurcuminirradiation microwaveUR-Student Paper Diploma
