The ability of Cinnamomum aromaticum essential oil for controlling Tribolium castaneum has good potential to compare with chemical pesticides because of its large secondary metabolites and high volatility. This study aims to determine the effectiveness of Cinnamomum aromaticum compared to chlorpyrifos chemical pesticides for controlling Tribolium castaneum using nanoparticle technology. The research methods consist of preparation, extraction, Cinnamomum aromaticum nanoparticle fabrication, chlorpyrifos chemical pesticides preparation, and Tribolium castaneum mortality test. The experiment was carried out in 24 hours using Cinnamomum aromaticum nanoparticles and chlorpyrifos chemical pesticides with various concentrations, 2%, 4%, 6%, and 8% for each treatment. The results showed that the higher of Cinnamomum aromaticum nanoparticles concentration, the higher the mortality of Tribolium castaneum. The most effective nanoparticle concentration, which has the highest mortality is 8%, with an average of mortality, is 5,331 ± 1,528. In the mortality test using chlorpyrifos, all concentrations lead to 100% mortality after 24 hours. This study concludes that Cinnamomum aromaticum nanoparticle has high potential to control Tribolium castaneum and can reduce the use of chlorpyrifos chemical pesticides which are harmful to humans, animals non-target, and environment. © 2019 Author(s).
