| Abstrak (Bhs. Indonesia) | Latar Belakang: Demam berdarah dengue (DBD) merupakan penyakit akibat virus Dengue yang ditularkan oleh nyamuk Aedes aegypti. Pencegahan DBD banyak menggunakan insektisida kimia yang tidak ramah lingkungan dan banyak mengalami resistensi. Tujuan: Penelitian ini bertujuan untuk mengetahui efek ekstrak daun Rasamala (Altingia excelsa) sebagai insektisida nyamuk Ae. aegypti. Metodologi: Metode penelitian menggunakan pendekatan eksperimental dengan desain post test only with control group menggunakan 500 ekor nyamuk Ae. aegypti betina berusia 3-5 hari yang diberikan paparan uap menggunakan alat electric liquid dan terbagi dalam 5 kelompok dengan total 4 pengulangan : kontrol positif, kontrol negatif, ekstrak 25%, ekstrak 50%, dan ekstrak 75%. Data dikumpulkan dengan menilai jumlah kematian nyamuk pada 8, 16, dan 24 jam setelah pemberian paparan. Hasil: Hasil menunjukkan bahwa ekstrak daun Rasamala memiliki efek sebagai insektisida nyamuk Ae. aegypti. Analisis bivariat menggunakan uji Kruskal Wallis didapatkan p-value sebesar 0,001, menunjukkan adanya perbedaan yang signifikan antara rerata kematian nyamuk Ae. aegypti pada berbagai konsentrasi ekstrak daun Rasamala. Uji Post Hoc menunjukkan bahwa ekstrak dengan konsentrasi 50% efektif dalam membunuh nyamuk Ae. aegypti. Analisis probit menunjukkan nilai Lethal Concentration (LC50) sebesar 182% sehingga ekstrak daun Rasamala memiliki nilai toksisitas sangat rendah. Lethal Time (LT50) memiliki nilai parameter estimate yang tidak signifikan sehingga nilai LT50 tidak dapat ditentukan. Kesimpulan: Pemberian ekstrak daun Rasamala (A. excelsa) memiliki efek sebagai insektisida nyamuk Ae. aegypti dengan konsentrasi paling efektif yaitu konsentrasi ekstrak 50%. |

| Abtrak (Bhs. Inggris) | Background: Dengue hemorrhagic fever (DHF) is a disease caused by the Dengue virus, which is transmitted by the Aedes aegypti mosquito. The prevention of DHF commonly involves the use of chemical insecticides, which are not environmentally friendly and often lead to resistance. Objective: The purpose of this study is to determine the effect of Rasamala leaf extract (Altingia excelsa) as insecticide against Aedes aegypti mosquitoes. Methodology: The research method used an experimental approach with a post-test only design with a control group, utilizing 500 female Aedes aegypti mosquitoes aged 3-5 days that were exposed to vapor using an electric liquid device. The mosquitoes were divided into 5 groups with a total of 4 repetitions: positive control, negative control, 25% extract, 50% extract, and 75% extract. Data were collected by assessing the number of mosquito deaths at 8, 16, and 24 hours after exposure. Results: The results indicate that the extract of Rasamala leaves has an effect as an insecticide against Aedes aegypti mosquitoes. Bivariate analysis using the Kruskal-Wallis test yielded a p-value of 0.001, indicating a significant difference in the average mortality of Aedes aegypti mosquitoes at various concentrations of Rasamala leaf extract. The Post Hoc test showed that the 50% extract concentration is effective in killing Aedes aegypti mosquitoes. Probit analysis revealed a Lethal Concentration (LC50) value of 182%, indicating that Rasamala leaf extract has very low toxicity. The Lethal Time (LT50) parameter estimate was not significant, thus the LT50 value could not be determined. Conclusion: The exposure of Rasamala leaf extract (A. excelsa) has an effect as an insecticide against Aedes aegypti mosquitoes, with the most effective concentration being the 50% extract concentration. |
