Effectiveness of Soursop Seed Extract (Annona muricata L) as a Natural Repellent on Aedes Aegypti

Background: Dengue Hemorrhagic Fever (DHF) is a disease caused by the dengue virus. City Regencies in Indonesia contracted DHF in 2014 amounting to 84.74%, 2015 amounted to 86.77%, and in 2016 amounted to 90.08%. Soursop plants can act as a repellent (insect repellent). The study aimed was to determine the effectiveness of soursop seed extract (Annona muricata L) as a natural repellent against Aedes aegypti mosquitoes. Method: The study was experimental with the independent variable concentration of soursop seed extract (Annona muricata L) and the dependent variable was Aedes aegypti mosquito that perched on the hand which had been sown with soursop seed extract (Annona muricata L). The sample of this study was 500 Aedes aegypti mosquitoes. This study used 5 concentrations and 5 repetitions for 6 hours of observation. The study was conducted on August 6-10 2018 starting at 08.30-13.30. Result: This study indicate that the concentration that concentrations of 20%, 40%, 60%, 80% and 100% have a mean of 75.2%, 90.8%, 93.5%, 95% and 97.7%, respectively. Based on the results of the ANOVA test, the results of the V-watch observation were obtained 61.60%, 85.07%, 89.89%, 92.88%, and 95.42% respectively. Conclusion: From the results obtained, the concentration of effective soursop seed extract is a concentration of 80% and 100% with a protection power of> 90%. The most effective concentration is 100%. It is recommended to the public to use soursop seed extract as a natural repellent to reduce the use of chemicals containing DEET (N, N-diethylmetatoluamide).
