Fitri, Mardhiyah (2017) Uji Perbandingan Potensi Ekstrak Etanol Daun Jeruk Nipis (Citrus Aurantifolia) Sebagai Insektisida Terhadap Nyamuk Aedes Aegypti Dan Nyamuk Culex Sp. Dengan Metode Semprot. Sarjana thesis, Universitas Brawijaya.
Abstract
Nyamuk Aedes aegypti dan nyamuk Culex sp. merupakan vektor dari beberapa penyakit seperti demam berdarah dengue, demam kuning (yellow fever), dan chikungunya, sedangkan filariasis limfatik, Japanese B Encephalitis, West Nile Virus, dan St. Louis Encephalitis dikarenakan nyamuk Culex sp. Sehingga, diperlukan insektisida alami untuk mengendalikan kedua vektor seperti ekstrak etanol daun jeruk nipis karena mengandung senyawa flavonoid, limonoid dan saponin. Flavonoid menyebabkan kelayuan pada saraf pernapasan yang menyebabkan tidak bisa bernafasnya vektor. Limonoid bekerja dengan mengganggu metabolisme tubuh nyamuk dan mempengaruhi fungsi saraf yang mengakibatkan tubuh nyamuk kejang. Sedangkan saponin dapat menurunkan jumlah sterol bebas yang mengakibatkan terganggunya proses pergantian kulit pada nyamuk. Ketiga hal tersebut menyebabkan kematian pada nyamuk Aedes aegypti dan nyamuk Culex sp. Penelitian ini menggunakan studi experimental, dilakukan pada 25 ekor nyamuk Aedes aegypti dan 25 ekor nyamuk Culex sp. yang dibagi menjadi 4 kelompok. Kelompok I sebagai kontrol negatif nyamuk Aedes aegypti menggunakan larutan acetone 1%. Kelompok II menggunakan larutan ekstrak etanol daun jeruk nipis 10% terhadap nyamuk Aedes aegypti. Kelompok III sebagai kontrol negatif nyamuk Culex sp. menggunakan larutan acetone 1%. Kelompok IV menggunakan larutan ekstrak etanol daun jeruk nipis 10% 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 One-Way ANOVA dengan p<0,05 dan T-Test untuk menguji perbandingan potensi ekstrak berdasarkan lama waktu paparan, dengan demikian ekstrak etanol daun jeruk nipis memiliki potensi sebagai insektisida terhadap nyamuk Aedes aegypti dan nyamuk Culex sp. secara signifikan. Kesimpulan penelitian ini adalah ekstrak etanol daun jeruk nipis memiliki potensi sebagai insektisida terhadap nyamuk Aedes aegypti dan nyamuk Culex sp.
English Abstract
Aedes aegypti and Culex sp. mosquitoes are the vectors of some diseases such as dengue haemorrhagic fever, yellow fever and chikungunya, and cholera because of the Aedes aegypti mosquitoes, meanwhile lymphatic filariasis, Japanese B Encephalitis, West Nile Virus, and St. Louis Encephalitis because of the Culex sp. mosquiotoes. Thus, it is required a natural insecticide to control vectors such as ethanol extract lime leaf because this plant contains flavonoids, limonoids and saponins, flavonoids cause withering of the respiratory nerves causes vectors cannot breathe. Limonoids disrupts the body’s metabolism of mosquitoes and affect nerve function resulting mosquitoes seizures. While saponins decrease free sterol in its body so it can disrupts moulting process. These three things are causing death of the Aedes eegypti and Culex sp. mosquitoes This research uses experimental study, it’s done with 25 Aedes aegypti and Culex sp. mosquitoes were divided into 4 groups. Group I as Aedes aegypti mosquitoes negative control that uses acetone 1%. Group II uses ethanol extract lime leaf with a concentration of 10% for Aedes aegypti mosquitoes. Group III as Culex sp. mosquitoes negative control that uses acetone 1%. Group IV uses ethanol extract lime leaf 10% for Culex sp. mosquitoes. The measured parameters were the number of Aedes aegypti and Culex sp. mosquitoes were dead by the time variation. Data analysis uses One-Way ANOVA method with p<0,05 and T-Test shows comparative potency of extract between Aedes aegypti and Culex sp. mosquitoes based of exposure time, therefore ethanol extract lime leaf has the potential as insecticide against Aedes aegypti and Culex sp. mosquitoes significantly. The conclusion is etanol extract lime leaf has potential effect as insecticide against Aedes aegypti and Culex sp. mosquitoes.
