Rajasegaran, Thanaganes (2017) The Biovicidal Activity Of Acalypha indica linn Against Aedes aegypti Eggs. Sarjana thesis, Universitas Brawijaya.
Abstract
Aedes aegypti was chosen as the specimen for this study because it serves as an important mechanical vector for Dengue Hemorrhagic Fever. Man made chemical Ovicide have proven to be highly effective in eradicating this pest but its negative effects upon human health and environmental safety are major drawbacks to its continued use. Hence, the search for alternative, natural substances such as Acalypha indica linn, that are both environmentally safe as well as being effective Ovicide. The extract of Acalypha indica linn is known to contain high concentrations of Flavonoid and Saponin.These substances are thought to have ovicidal properties. This study aims to identify the effect of Acalypha indica linn extract against Aedes aegypti eggs using a contact poison method. A true experimental study was conducted, using specimens of Aedes aegypti. at four concentrations of Acalypha indica linn extract; 0,5%, 1,0%, 1,5%, and 2,0% with 1 negative control using well water, and also 1 positive control using abate 10%. The experiment was repeated four times and each repetition was observed at four time intervals (12th hour, 24th hour, 36th hour, and 48th hour). There were no significant difference between a concentration of 0.5%, 1.0% and 1.5%. The result of the effect of ethanol extract of root(Acalypha indica linn) as ovicidal to the eggs of mosquitoes (Aedes aegypti) was performed using Bonferroni test informs that the negative control (water wells) producing eggs of mosquitoes (Aedes aegypti), which become larvae most numerous and differ significantly from the positive control (abate 10%). Analysis results of the effect of treatment time of 48 hours, produced number of unhatched eggs of mosquitoes (Aedes aegypti), which differed significantly with treatment time of 12 hours. It is concluded that Acalypha indica linn root extract has ovicidal activity against Aedes aegypti eggs and the higher the concentration , the greater the ovicidal activity.
English Abstract
Telur Aedes aegypti dipilih karena merupakan vektor mekanis untuk penyakit seperti Demam Berdarah. Ovisidal kimiawi memiliki efektifitas tinggi dalam membunuh telur tetapi juga memiliki efek samping yang merugikan terhadap manusia dan lingkungan. Oleh karena itu sebaiknya digunakan ovisidal alami seperti akar Acalypha indica linn karena bersifat mudah terurai sehingga penggunaannya relatif aman. Acalypha indica linn diduga mengandungi zat aktif flavonoid dan saponin. Zat-zat ini diduga mempunyai efek ovisidal. Penelitian ini bertujuan untuk menguji efek ekstrak etanol kulit jeruk nipis sebagai ovisidal terhadap telur Aedes aegypti. Penelitian ini merupakan ‘penelitian true experimental-post test only control group design’ dengan sampel yang digunakan adalah telur Aedes aegypti . Pengulangan dilakukan sebanyak empat kali dengan jumlah perlakuan sebanyak enam jenis yaitu kontrol negatif (air sumur), konsentrasi larutan ekstrak kulit jeruk nipis sebesar 0,5%, 1,0%, 1,5% dan kontrol positif (abate). Setiap perlakuan diamati pada empat interval waktu yaitu pada 12 jam, 24 jam, 36 jam, dan 48 jam. Hasil penelitian menunjukkan bahwa pada konsentrasi 1,5%, sudah tidak ada telur yang menetas menjadi larva pada pengamatan 48 jam.Tidak didapatkan perbedaan yang signifikan dan bermakna antara konsentrasi 0,5%, 1,0%, 1,5%, dan 2.0%. Hasil uji pengaruh pemberian ekstrak etanol kulit jeruk nipis (Citrus aurantiifolia) sebagai ovisidal terhadap telur nyamuk (Aedes aegypti) yang dilakukan menggunakan Bonferroni Test menunjukkan bahwa kontrol negatif (air sumur) menghasilkan telur nyamuk (Aedes aegypti) yang menjadi larva paling banyak dan berbeda signifikan dengan kontrol positif (abate 10%). Hasil analisis pengaruh waktu perlakuan dengan telur yang tidak menetas menunjukan bahwa konsentrasi perlakuan 2.0% menghasilkan telur nyamuk (Aedes aegypti) yang tidak menetas paling banyak dan berbeda signifikan dengan konsentrasi perlakuan 0.5%. Kesimpulan dari penelitian ini adalah ekstrak akar Acalypha indica linn mempunyai efek sebagai ovisidal terhadap Telur Aedes aegypti dan semakin tinggi konsentrasi maka efek ovisidal semakin besar.
