Abstract
Nanoemulsion is a material which consists of oil and water phases with particle size in the range of 20-200 nm. The purpose of this research is to obtain a botanical insecticide nanoemulsion made from T. vogelii which is active against C. pavonana. Nanoemulsion made using low energy method whch is spontaneous emulsification using a magnetic stirrer. This research produced 12 formulas. Four best formulas chosen for PSA (Particle Size Analizer) analysis. Four formulas was selected based on the toxicity of each formula. Nanoemulsion was analyzed for PSA using Malvern's Zetasizer Nano (ZN). The analysis results showed nanoemulsion A.1, A.2, B.1.a and B.1.b had particle sizes in a row of 134nm, 156nm, 1292nm, and 1286nm. Formulas A.1 and A.2 have fulfilled the nanoemulsion requirements and criteria, otherwise formulas B.1.a and B.1.b have not classified as nano-sized material, so they cannot be categorized as nanoemulsions. Formulas A.1, A.2, B.1.a and B.1.b have LC_95 values is 1.09%, 3.15%, 0.45% and 2.26%.
