Pemberantasan nyamuk Aedes aegypti sebagai upaya pencegahan penyakit demam berdarah dengan menggunakan insektisida alami. Tujuan Penelitian ini untuk mengatahui efektivitas ekstrak kombinasi daun sirsak, serai wangi dan daun papaya terhadap mortalitas larva Aedes aegypti. Jenis penelitian adalah eksperimen, objek penelitian ini adalah larva Aedes aegypti instar III. Jumlah larva Aedes aegypti yang digunakan 20 ekor satu perlakuannya. Perlakuan dalam penelitian ini menggunakan varian ekstrak daun sirsak kombinasi serai wangi, daun sirsak kombinasi daun papaya dan serai wangi kombinasi daun pepaya dengan konsentrasi 25%, 50%, 75%. Pengulangan yang dilakukan sebanyak 3 kali. Dan diamati, 6 pengamatan pertama diamati sekali 1 jam dan pengamatan berikutnya diamati sekali 6 jam. Hasil penelitian menunjukkan pada konsentrasi 25%, 50% dan 75% rata rata tertinggi ada pada ekstrak daun sirsak kombinasi serai wangi. Hasil uji analisis menunjukkan bahwa tidak ada perbedaan rata-rata kematian larva antara 3 kombinasi pada konsentrasi 25% dan 75%. Sedangkan pada 3 kombinasi konsentrasi 50% ada perbedaan rata-rata kematian larva. Dan tidak ada perbedaan rata-rata kematian larva pada ekstrak daun sirsak kombinasi serai wangi konsentrasi 25%, 50%, 75%. Sehingga dapat diambil kesimpulan bahwa ekstrak daun sirsak kombinasi serai wangi konsentrasi 25%, 50% dan 75% dapat dijadikan larvasida untuk membunuh larva Aedes aegypti karena rata-rata kematian larva pada ketiga konsentrasi ekstrak daun sirsak kombinasi serai wangi ini tidak berbeda jauh. Namun lebih disarankan agar menggunakan ekstrak daun sirsak kombinasi serai wangi konsentrasi 25% karena lebih hemat bahan serta efektifitasnya sama dengan konsentrasi 50% dan 75%.

The eradication of Aedes aegypti mosquitoes is a crucial step in preventing dengue fever, often achieved through the use of natural insecticides. The aim of this research is to determine the effectiveness of a combination of soursop, lemongrass, and papaya leaf extracts on the mortality of Aedes aegypti larvae. This study employs an experimental design, focusing on third instar Aedes aegypti larvae as the research subjects. Each treatment involves 20 larvae. The research treatments consist of various combinations of soursop leaf extract, soursop leaf extract combined with papaya leaf extract, and lemongrass leaf extract combined with papaya leaf extract, each with concentrations of 25%, 50%, and 75%. Each treatment is repeated three times. Observations were made at six intervals, with the first six observations recorded after one hour, and subsequent observations recorded after six hours. The research findings indicate that at concentrations of 25%, 50%, and 75%, the highest average mortality rate is achieved with the combination of soursop leaf extract and lemongrass leaf extract. Statistical analysis results reveal no significant difference in the average larval mortality rates among the three combinations at concentrations of 25% and 75%. However, at a concentration of 50%, there is a significant difference in the average larval mortality rates among the three combinations. Furthermore, there is no significant difference in the average larval mortality rates for soursop leaf extract combined with lemongrass leaf extract at concentrations of 25%, 50%, and 75%. In conclusion, soursop leaf extract combined with lemongrass leaf extract at concentrations of 25%, 50%, and 75% can be effective larvicides for killing Aedes aegypti larvae, as the average larval mortality rates for these three concentrations do not differ significantly. However, it is recommended to use a 25% concentration of soursop leaf extract combined with lemongrass leaf extract due to its cost effectiveness, as it yields the same level of effectiveness as the 50% and 75% concentrations.
