Adril, Riri (2019) Uji Perbandingan Potensi Ekstrak Etanol Daun Mint (Mentha arvensis) Sebagai Insektisida terhadap Nyamuk Aedes aegypti dan Nyamuk Culex sp Dengan Metode Semprot. Sarjana thesis, Universitas Brawijaya.
Abstract
Nyamuk Aedes aegypti dan Culex sp merupakan vektor dari beberapa penyakit seperti demam berdarah dengue, demam kuning, chikungunya, filariasis limfatik, Japanese B Encephalitis, West Nile Virus, dan St, Louis Encephalitis. Sehingga, diperlukan insektisida alami untuk mengendalikan kedua vektor seperti ekstrak etanol daun mint karena mengandung senyawa flavonoid, saponin, tanin, dan minyak atsiri. Flavonoid menyebakan kelayuan pada saraf pernafasan yang menyebabkan vektor tidak bisa bernafas. Saponin bekerja dengan menurunkan jumlah sterol yang mengakibatkan terganggunya proses pergantian kulit pada nyamuk. Tanin menghalangi nyamuk dalam mencerna makanan yang diperlukan untuk pertumbuhan sehingga proses pencernaan,pertumbuhan dan kelangsungan hidup nyamukk akan terganggu. Sedangkan minyak atsiri bersifat neurotoxic pada nyamuk dengan menghambat acetylcholinesterase (AChE) atau dengan memblok reseptor octopamine. Keempat hal tersebut menyebabkan kematian pada nyamuk Aedes aegypti dan nyamuk Culex sp. Penelitian ini menggunakan studi true experimental post-test only control grup design dilakukan pada 20 ekor nyamuk Aedes aegypti dan 20 ekor nyamuk Culex sp. yang dibagi menjadi 4 kelompok. Kelompok I sebagai kontrol negatif nyamuk Aedes aegypti menggunakan larutan aquades. Kelompok II menggunakan larutan ekstrak etanol daun mint 25% terhadap nyamuk Aedes aegypti. Kelompok III sebagai kontrol negatif nyamuk Culex sp menggunakan larutan aquades. Kelompok IV menggunakan larutan ekstrak etanol daun mint 25% terhadap nyamuk Culex sp. Parameter yang diukur adalah jumlah nyamuk Aedes aegypti dan nyamuk Culex sp yang mati berdasarkan variasi waktu. Analisis data menggunakan metode Kruskal-Wallis dengan p < 0,05 dan uji Mann-Whitney untuk menguji perbandingan potensi ekstrak etanol daun mint persatuan waktu. Kesimpulan penelitian ini ekstrak etanol daun mint mempunyai potensi sebagai insektisida terhadap nyamuk Aedes aegypti dan nyamuk Culex sp dan potensi ekstrak etanol daun mint terhadap nyamuk Culex sp lebih besar dibandingkan terhadap nyamuk Aedes aegypti pada enam jam pertama.
English Abstract
Aedes aegypti and Culex sp mosquitoes are vectors of several diseases such as dengue hemorrhagic fever, yellow fever, chikungunya, lymphatic filariasis, Japanese B encephalitis, West Nile Virus, and St., Louis Encephalitis. So, natural insecticides are needed to control both vectors such as the ethanol extract of mint leaves because they contain flavonoids, saponins, tannins and essential oils. Flavonoids cause wasting on the respiratory nerves which causes vectors to be unable to breathe. Saponins work by decreasing the number of sterols which results in disruption of the skin turnover process in mosquitoes. Tanin prevents mosquitoes from digesting food needed for growth, so the process of digestion, growth and survival of mosquitoes is disrupted. While essential oils are neurotoxic in mosquitoes by inhibiting acetylcholinesterase (AChE) or by blocking octopamine receptors. These four things cause death in Aedes aegypti mosquitoes and Culex sp. Mosquitoes. This study uses the study of true experimental post-test only control group design carried out on 20 Aedes aegypti mosquitoes and 20 Culex sp mosquitoes. which are divided into 4 groups. Group I as negative control of Aedes aegypti mosquito using distilled water solution. Group II uses 25% ethanol extract of mint leaves on Aedes aegypti mosquitoes. Group III as negative control of Culex sp mosquitoes using distilled water solution. Group IV uses a leach of 25% mint ethanol extract against Culex sp. The parameters measured were the number of dead Aedes aegypti and Culex sp mosquitoes based on time variations. Data analysis using the Kruskal-Wallis method with p < 0.05 and the Mann-Whitney test to test the potential comparison of ethanol extract of mint leaves unity of time. The conclusion of this study is that the mint ethanol extract has potential as an insecticide against Aedes aegypti and Culex sp mosquitoes and the potential for the ethanol extract of mint leaves on Culex sp mosquitoes is greater than that of the Aedes aegypti mosquito in the first six hours. Keywords: mint leaves, insecticides, Aedes aegypti and Culex
