Abstract : This research aims to synthesize silver nanoparticles (AgNPs) using Kirinyuh (Chromolaena odorata) leaf extract with different temperature and evaluate its activity in Vibrio sp. The synthesis was carried out by combining between silver nitrate solution and Kirinyuh leaf extract at room temperature (AgNPs 200) and hydrothermal process at 60oC (AgNPs 200*). Based on the results of LC-MS analysis, most of the chemical content of an extract was a flavonoid group compound. The color of the solution changed from colorless to red-brown, and a new peak around 435 nm showed that silver nanoparticles have been successfully obtained. The hydrothermal process exhibits sharp peaks rather than without hydrothermal treatment. The silver nanoparticles have a definite crystalline structure. The FTIR spectroscopy analysis indicated the organic compound was responsible for capping and stabilizing agents. In addition,TEM analysis showed that AgNPs 200 and AgNPs 200* exhibited average particle size of 32.89 nm and 27.82 nm, respectively. The presence of AgNPs can enhance the zone of growth inhibition of Vibrio sp approximately 300% compared to Kirinyuh leaf extract. Silver nanoparticles is estimated to possess the potential to be further evolved and utilized to inhibit the growth of Vibrio sp bacteria in shrimp agriculture.
