Abstract
Dengue Hemorrhagic Fever (DHF) is a disease transmitted through Aedes aegypti mosquitoes and almost always occurs in several regions in Indonesia every year. One alternative to overcome this problem is to use an anti-mosquito mat which is generally made from synthetic chemicals. The more environmentally friendly method is to use cempedak stem bark as a mosquito repellent mat. This study aims to determine the effectiveness of electric mosquito repellent mat from cempedak stem bark with varying concentrations. This research was carried out at the Chemistry Laboratory of FMIPA Medan State University with extraction methods namely socletation. Cempedak stem bark extract was obtained from socletation with methanol which was evaporated to produce thick cempedak stem bark extract. Then, the extract is dissolved into concentrations of 15%, 20%, 25%, 30%, and 35%. The research data obtained was the death of Aedes aegypti which was then analyzed by Variant Analysis Statistics Test (ANOVA) and Post Hoc Test. The ANOVA test results obtained that between treatments have a significant value of 0.0002. This indicates that there are significant (real) differences from the five treatment groups. Post Hoc test to determine the most effective concentration. The results show that the most effective concentration as an electric mosquito repellent mat is 30%.
