Botanical insecticide nanoemulsion is an insecticide with a transparent emulsion system and is an oil and water dispersion stabilized by a surfactant molecule, which has a size ranging from 50 to 500 nm. The experiment was conducted in Biota Sumatera Laboratory Faculty of Pharmacy and Insect Bioecology Laboratory Faculty of Agriculture Andalas University Padang on from 2018 July to August. The purpose of this research was to obtained the nanoemulsion of Piper aduncum fruit as a botanical insecticide capable of controlling the pest of cabbage larvae Crocidolomia pavonana. The experimental design was used Completely Randomized Design (CRD) that consist of control treatment and nanoemulsion treatment of P. aduncum. Observations were used PSA with Zetasizer Nano ZS Malvern tools. Insecticidal activity of nanoemulsion were tested against C. pavonana. The result show that nanoemulsion have a particle size, polydispersity index, zeta potential, and distribution width. Nanoemulsion has an average size ranging from 18.56 to 216.7 nm, polydispersity index ranging from 0,202 to 0,371, zeta potential ranging from -0,410 to -28,7 mV, and distribution width ranging from 8,11 to 5570 nm beside, has insecticidal activity against C. pavonana.
