The treatment used is the concentration of tuba root extracts 0 g.l-1 of water, 25 g.l-1 of water, 50 g.l-1 of water, 75 g.l-1 of water and 100 g.l-1 of water. The result in them showing that the treatment of tuba root extract concentration of 75 g.l-1 water was able to control Oryctes rhinoceros larvae with a total mortality of 82.5%, the initial time of death is 15 hours, lethal time 50 is 27 hours, and the right concentration to kill 50% of the Oryctes rhinoceros larvae is 1,0% or equivalent to 10 g.l-1 of the root extract of tuba root extract.
