| Abstrak (Bhs. Indonesia) | Latar Belakang : Nyamuk Culex sp. merupakan vektor yang membawa cacing filaria penyebab penyakit filariasis, beberapa wilayah di Indonesia masih menjadi endemis filariasis. Upaya untuk mengurangi angka filariasis adalah dengan mengendalikan vektor, salah satunya dengan larvasida. Larvasida kimia dapat merusak ekosistem setempat, sehingga diperlukan larvasida alami yang ramah lingkungan dan efektif mematikan larva nyamuk Culex sp., yaitu dengan tanaman rasamala (Altingia excelsa). Tujuan : Mengetahui efektivitas ekstrak daun rasamala sebagai larvasida nyamuk Culex sp.. Metode : Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) studi post test only with control group design dengan enam kelompok perlakuan yaitu kontrol positif (Abate), kontrol negatif (Etil asetat), dan kelompok perlakuan diberi ekstrak daun rasamala (2%,3%,4%, dan 5%). Perlakuan menggunakan 25 larva instar III/IV Culex sp. dengan pengulangan 4 kali. Analisis dilakukan secara univariat dan bivariat berupa uji normalitas, uji Kruskall-Wallis, uji post hoc dan uji probit. Hasil : Persentase kematian larva setelah diberi perlakuan selama 24 jam termasuk kontrol positif terdapat 100% larva mati dan kontrol negatif 0% larva mati. Hasil uji Kruskal-Wallis menunjukan terdapat perbedaan rata-rata kematian larva Culex sp. dengan nilai signifikan p-value <0,05 (p=<0,001) dilanjut dengan uji post hoc didapatkan antara kontrol negatif dengan setiap konsentrasi memiliki perbedaan bermakna. Hasil Uji probit menunjukan πΏπΆ50 sebesar 0,63% dan πΏπ50 tercepat pada konsentrasi 5% yaitu 0,9 jam atau 54 menit. Kesimpulan : Ekstrak daun rasamala memiliki efektivitas sebagai larvasida nyamuk Culex sp. |

| Abtrak (Bhs. Inggris) | Background : Culex sp. mosquitoes is a vector that carries the filarial worms caused a filariasis disease, which remains endemic in several regions of Indonesia. Vector control through the use of larvacide is one of the efforts to reduce the incidence of filariasis. However, the use of chemical larvacides can harm the local ecosystem, which necessitates the development of natural larvacides that are environmentally friendly and effective in killing Culex sp. mosquito larvae, such as Rasamala leaves (Altingia excelsa). Objective : To determine the effectiveness of Rasamala leaf extract as a larvicide against Culex sp. mosquito larvae. Method : The research used a Completely Randomized Design (CRD) with a post test only control group design, involving six treatment groups : positive control (Abate), negative control (Ethyl acetate), and four concentrations of Altingia excelsa leaf extract (2%,3%,4%, and 5%). Each treatment group consisted of 25 instar larvae III/IV Culex sp., with four replications. The data were analyzed using normality test, Kruskal-Wallis test, post hoc test, and probit analysis. Result : The results showed that all treatment groups, including the positive control, achived 100% larvae mortality 24 hours after treatment, and the negative control group showing 0% mortality. Kruskal-Wallis analysis indicated a significant difference in the average mortality rate of Culex sp. larvae with p-value <0,05(p=0,001), followed by post hoc test which showed significant differences between the negative control and each concentration. Probit analysis showed an πΏπΆ 50 equals to 0,63%, and πΏπ 50 with the fastest at 5% concentration which was 0,9 hours or 54 minutes. Conclusion : Rasamala leaf extract is effective as larvicide against Culex sp. mosquito larvae. |
