Pollination is the transfer of pollen from the anther to the stigma resulting in fertilization events. Elaedobius kamerunicus Faust (Coleoptera: Curculionidae) has been identified as the most effective pollinator beetles on plant oil palm. This study aims to calculate the amount of pollen on the female flowers using a pollen trap, calculate the amount of pollen that sticks to the body of male and female beetles both male flowers and female flowers on and the effect on the percentage of fruit set. Installation was done when the trap perfectly receptive flowers. The percentage of fruit set of counting the whole fruit of the oil palm fruit bunch. Data was analyzed using SPSS'16 program. The results showed that the amount of pollen in the trap between stigma is higher than the air trap and pistils, although not statistically significantly different. The amount of pollen per cluster area is 48.83 / cm2 (June) and 56.4 / cm2 (August). The results also show the amount of pollen in the beetle's body on the male flower in June (3881 ± 2204) more than in the female flowers (475 ± 379) and not statistically significant. The same trend was also obtained in August. The results of calculations pollen delivery on June and August ranged from 11.9% to 12.9%. From these results it can be concluded that the amount of pollen around the female flowers was positively correlated with the percentage of fruit set formation.
