Oryctes rhinoceros is one of the main pests in oil palm. These pest can reduce production until 69%, even causing 25% of young plants to die. Control efforts conducted by smallholders or large companies generally use synthetic insecticides. To reduce the effects of synthetic insecticides, one of the alternatives that can be used in the technique of pest control O. rhinoceros is by the used of natural insecticides. One of the plants that can be used as a natural insecticides is piper betle forest (Piper aduncum L.).The purpose of this research is to find out the ability of the extract of piper betle forest in extermination larvae O. rhinoceros in oil palm. The research was conducted from March 2017 to June 2017 at the Pest Laboratory Plants and Experiment Station Technical Implementation Unit Agriculture Faculty University of Riau. The research was done experimentally with Completely Randomized Design (CRD). Which consists of 3 experimental stages. The first piper bettle forest experiment was consisted of 3 levels; they were leaf flour extract, fruit flour extract and twig flour extract. The second experiment consisted of 5 concentration; they ware 0 g/l water, 25 g/l water, 50 g/l water, 75 g/l water, dan 100 g/l water. The third experiment was the test at 3 thickness EFB, they ware; 10, 20 and 30 cm. The research used 2 methods, those were; methods of mixing food and watering methods. The result showed that concentration of 100 g/l piper betle forest of fruit flour extract with the application of food mixing methods and watering methods, can kill the larvae up to 92% and 80%, with an average initial time of death of 12 hours and 28,8 hours. Piper betle forest of fruit flour extract was an effective extermination larvae O. rhinoceros in oil palm because it caused the death rate of larvae O. rhinoceros more than 80%. fruit flour extract can control pest larvae O. rhinoceros until the thickness of EFB 30 cm with mortality rate reached 72%-84%
