Abstract

Latar belakang: Penyakit Demam Berdarah masih menjadi salah satu masalah kesehatan hingga saat ini. Banyak cara dilakukan untuk menurunkan atau memberantas penyebab penyakit ini, salah satunya dengan pengendalian vektor. Penggunaan insektisida berbahan kimia dalam jangka panjang dapat menimbulkan gangguan kesehatan dan resistensi terhadap vektor.
Tujuan: Penelitian ini bertujuan untuk mengetahui potensi nanopartikel perak ekstrak daun pepaya(C. papaya L) sebagai insektisida elektrik cair terhadap nyamuk Aedes aegypti.
Metode: Jenis penelitian eksperimen dengan desain post test only control group design. Sampel penelitian inisebanyak 450 ekor nyamuk Aedes aegypti terbagi dalam enam kelompok. Kelompok I adalah kontrol negatif, Kelompok II adalah kontrol positif, Kelompok III adalah 10 ppm, Kelompok IV adalah 20 ppm, kelompok V adalah 30 ppm, Kelompok VI adalah 40 ppm. Masing-masing diaplikasikan menggunakan elektrik listrik cair diamati selama 3 jam dan 24 jam.
Hasil: Hasil penelitian menunjukan bahwa konsentrasi 40 ppm sudah dapat membunuh 89,33% nyamuk Aedes aegypti. Di waktu pengamatan 24 jam mendapatkan nilai LC50 26,974 ppm dan LC90 45,112 ppm uji mann whitney pada setiap konsentrasi rata-rata p 0,037 (p=<0,05).
Kesimpulan: Nanopartikel ekstrak daun pepaya dapat berpotensi insektisida elektrik cair terhadap nyamuk Aedes aegypti
Keywords : Aedes aegypti, daun pepaya (Carica papaya L), elektrik cair, nanopartikel

Background: Dengue Fever is still one of the health issues worldwide. There are basically many ways to reduce or eradicate the causes of this disease, one of which is vector control. The long-term use of chemical insecticides can cause health problems and resistance to vectors.
Aim: This study aimed to determine the potential of silver nanoparticles of C. papaya L leaf extract as a liquid electric insecticide against Aedes Aegypti mosquitoes.
Method: This was an experimental research using pretest-posttest control group design. The samples of this research were 450 Aedes aegypti mosquitoes which were divided into six groups. Group I was the negative control, Group II the positive control, Group III was 10 ppm, Group IV was 20 ppm, Group V was 30 ppm, Group VI was 40 ppm. Each was applied using liquid electric insecticide and observed for 3 hours and 24 hours.
Results: The results showed that a concentration of 40 ppm were able to kill 89.33% of Aedes aegypti mosquitoes. In the 24-hour observation time, LC50value of 26.974 ppm and LC90value of 45.112 ppm were obtained. In addition, Mann-Whitney test at each granule concentration obtained an average of p 0.037 (p<0.05).
Conclusion: Papaya leaf extract nanoparticles have the potential as an alternative to liquid electric insecticide that damage and kill Aedes aegypti mosquitoes.
Keywords: Aedes aegypti, papaya (Carica papaya L) leaf, liquid electric, nanoparticles
