The essential oils of nine plants from citronella oil of Cymbopogon Nardus spp., galangal oil of Alpinia galanga (L.) Willd., ginger oil of Zingiber officinale Roscoe., betel oil of Piper betle L., nutmeg oil of Myristica fragrans Houtt., sweet basil oil of Ocimum basilium spp., cinnamon oil of Cinnamomum Zeylamicum Nees., peppermint oil of Mentha cordifolia Opiz ex Fresen and garlic oil of (Allium sativum L.). A mosquito repellent dose-response study at a concentration of 5% time oil can completely prevent the Aedes aegypti, with an average time of 70.14 ± 5.30, 27.08 ± 2.29, 38.54 ± 5.20, 14.74 ± 1.54, 16.28 ± 3.36, 52.43 ± 2.68, 17.88 ± 1.52. , 63.63 ± 6.11, 47.93 ± 2.70 minutes, and at the concentration of 10% can completely prevent of the Aedes aegypti, with an average time 0f 96.96 ± 13.57, 49.74 ± 1.74, 64.77 ± 5.71, 27.21 ± 2.63, 19.13 ± 3.89, 96.58 ± 10.32, 23.57 ± 2.81, 113.02 ± 8.47, 64.05 ± 2.80 minutes respectively. A period of time to completely prevent Aedes aegypti from the combination of the three oils that has highest repellents time which are citronella oil, basil oil and peppermint oil was tested. It was found that the effectiveness of Aedes aegypti prevention was 306.10 ± 28.14 minutes and the satisfaction test was at a very good level with average score of 4.24 ± 0.54.
