Background: Control of Aedes aegypti mosquito by using synthetic insecticides has potential effect to environmental pollution and increase the resistance of target vectors. It is needed to search the proper methods in controlling Aedes aegypti which is environmentally friendly.
Materials and Methods: This study used coffee grounds as inhibiting factor in mortality process and inhibiting the growth of Aedes aegypti larva. This study was an experimental design, conducted in June-August 2016 in the laboratory of Environmental Health, Polytechnic of Health Banda Aceh. The doses were 28/liter, 30g/liter, 31g/liter, 33g/liter, and 34g/liter. The mortality data were analyzed by ANOVA, followed by Least Significant Difference (LSD) test and probit test. Growth data were analyzed by using GI (Growth index) and RGI (Relative growth index).
Results and Discussion: The results showed that the grounds of arabica coffee was capable of causing the death of Aedes aegypti larva (p=0.00). The treatments with coffee ground also caused a decrease in GI and RGI values, which means that it inhibited the growth of larva.
