lemongrass extraction oil. Treatment 3: 100% of lemongrass extraction oil. The
method used for lemongrass oil’s extraction is steam-distillation. The Tilapia was
infected by Aeromonas hydrophila by using immersion method (10 7 CFU mL -1 ). Each
treatment and control has three replicate. In day 6, the mortality for the treatment is
