Petroleum reserves continue to decline, providing challenges and opportunities in the development of renewable energy, for example the use of biodiesel. Tobacco seed oil is known to be used as biodiesel through transesterification reaction with methanol by means of base catalyst such as CaO-KCl. Methyl ester can be used as biodiesel and also has the potential to be used as an antibacterial compound. The objectives of this study were 1) to synthesize methyl ester from tobacco seed oil using catalysts CaO-KCl assisted by ultrasonic, 2) to characterize methyl ester and its potential as a biodiesel, 3) to determine the component compounds of the methyl esters by GC-MS, and 4) to test the bioactivity of antibacterial oil seeds tobacco and methyl esters on the bacterium Escherichia coli. The results of the study showed that 1) synthesized methylester obtained using catalyst of CaO-KCl 3, 4, and 5% w/w oil produced yields of 63.12; 64.78; and 70.29% methylester respectively 2) the character of methylester is qualify in SNI standard of Biodiesel, 3) synthesized methylester that was analized using GC-MS indicate the presence of methyllinoleate 35.64%, methyloleate 20.99%, and methylpalmitate 12.98%, and 4) methylester synthesized with CaO-KCl catalyst had moderate antibacterial bioactivity against Escherichia coli bacteria. © 2023 American Institute of Physics Inc..
