As a plant cultivated from generation to generation in Kubu District, Kubu Raya Regency, coconut plants face pest attacks. Most of the coconut trees are badly affected by the rhinoceros beetle (Oryctes rhinoceros Linn). The impact of pest attacks caused a drastic decrease in coconut productivity. Community service activities are carried out using lecture and practical methods. The lecture material aims to provide provisions for the community about protecting coconut plants against rhino beetle pests. The practical method was carried out by transferring technology in the form of multiplication of isolates of Metharhizum spp. in the media of maize and beetle larvae and making rhino beetle traps using a pile of coconut garden waste and trapping with pheromones. The activity results showed that the participants mastered the propagation of Metharhizum spp both on maize and larval media. Participants can make rhino beetle traps using garden waste. Laying traps at 6 points for ten weeks shows that the rhino beetle population in coconut plantations is high. Overall, the use of Metarhizium mushrooms and pheromones was able to reduce the rhino beetle population. Rhino beetle control will be useful if done by every coconut farmer and carried out continuously until the pest population is below economic threshold
