The importance of mosquito control lies in mosquitoes as vectors of dangerous diseases such as dengue fever. The use of chemical insecticides, although common, has a negative impact on human health and the environment. The Aedes aegypti mosquito can cause dengue fever. The response is to carry out the vector life cycle, by killing mosquito larvae, using fogging, abate powder, which has an impact on the environment. Researchers are looking for a safe and effective natural larvicide solution. The researchers observed marigold plants at the research site. Marigold plants contain essential oils that are effective as larvicides on Culex quinquefasciatus, Anopheles stephensi and Aedes aegypti mosquitoes. This study aims to test the effectiveness of squeezed leaves and flowers of marigold plants on mosquito repellent power. This study is a quasi-experimental study. The research location is in a room with a mosquito net box containing 140 mosquitoes. The results of the Chi-square analysis obtained the p-value = 0.039 indicates a statistically significant positive effect of marigold leaf slices as a mosquito repellent, with an odds ratio of 4.8 times. The effectiveness of marigold leaf juice on mosquito repellent. The chi-square analysis results obtained with a p-value = 0.040 indicate a statistically significant positive effect of marigold leaf slices as a mosquito repellent, with an odds ratio of 4.9 times. The effectiveness of marigold flower juice on mosquito repellent.
