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).
