Uji Efikasi Nanoinsektisida Komposisi Perak Tembakau (Nicotiana tabacum) terhadap Aedes aegypti

Vector control that used insecticides need to be substituted, because it has a negative impact for the environment and have been resistance for some areas, so it was necessary to find alternative insecticides. One of the natural insecticides was tobacco (Nicotiana tabacum). The chemical content of tobacco leaves included alkaloids, saponins, and flavonoids. Nicotine was an alkaloid group compound in tobacco, thatwas a nerve poison that reacts quickly and can act as a contact poison in insects, to add the effectiveness it’s necessary change to nano particle with silver. Besides, this test used two solvents with different contains of mineral to compare the effectiveness. This study aimed to test effication of nanoinsecticide from formulation tobacco (Nicotiana tabacum) and silver particle for vector control of larvae Ae.aegypti. It was held at the Center for Research and Development of Disease Vector and Reservoir (B2P2VRP) with an experimental method. The results of the study showed 1,153 ppm LC50, 1,719 ppm LC90 and 1,925 ppm LC90 on solvent distilled water. LC50 of 1,641 ppm, LC90 of 10,741 ppm and LC90 of 18,295 ppm in solvent aquademineralization. Measurements of tobacco nanoinsecticides are known to be 89,2 – 112,0 run in aquadest and 89,2 -112,0 μm in aquademineralization solvents 79,0 – 143,7μm. Abstrak Pengendalian vektor menggunakan insektisida kimiawi perlu disubstisusi karena berdampak buruk pada lingkungan dan menyebabkan resistensi di beberapa daerah, sehingga perlu untuk mendapatkan insektisida alternatif yang ramah lingkungan. Salah satu tanaman insektisida alam, adalah tembakau (Nicotiana tabacum). Kandungan kimia tembakau meliputi alkaloid, saponin, dan flavanoid. Nikotin termasuk senyawa alkaloid dalam tembakau merupakan racun syaraf dengan reaksi cepat serta dapat berfungsi sebagai racun kontak serangga. Namun, untuk menambah daya bunuhnya sebagai larvasida maka ukuran partikel alkaloid perlu dipecah contohnya dengan penambahan perak. Pemilihan perak sebagai pembentuk molekul nano, ...
