Abstrak
Ganoderma boninense is one of the pathogenic organisms in oil palm which causes rot on the base of oil palm trunk. As a solution, farmers use pesticides to inhibit the growth of G. boninense. However, such treatment may cause environmental pollution. Therefore, biological control needs to be used to overcome these problems, one of which is by utilizing endophytic fungi from vetiver (Vetiveria zizanioides L.). This study aimed to isolate the fungus G. boninense which causes root rot disease and to determine the potential of endophytic fungi from vetiver (V. zizanioides L.) in inhibiting the growth of G. boninense. G. boninense fungi were isolated using the surface sterilization method. The antagonist test against G. boninense was then performed using a dual culture assay method. Based on macroscopic observation, G. Boninense's isolation had the characteristics of a circular colony, the edges of the colony were wavy and white, like cotton. On microscopic observation, it was also found that the conidia was oval, blackish-gray in color, where the conidiophores were straight with a blackish gray color. The greatest potential found based on the endophytic fungal antagonist test from vetiver against G. boninense in IH1 isolates was the percentage with an inhibitory power of 43.
