Binatang (P2B2) Ciamis dengan judul "Efektivitas Ekstrak Daun Sereh (Cymbopogon nardus) Sebagai Antioviposisi Terhadap Nyamuk Aedes aegypti" Metode yang digunakan dalam penelitian ini adalah metode eksperimen dengan tujuan penelitian untuk mengetahui jumlah telur yang diletakkan nyamuk Aedes aegypti dengan konsentrasi 0%, 35%, 40%, 45%, 50% dan 55% yang di letakkan pada kandang yang berisi 15 ekor nyamuk. Penelitian ini dilakukan tiga kali pengulangan dan di lakukan selama tiga hari. Variasi konsentrasi dibuat berdasarkan uji pendahuluan yang dilakukan sebelum penelitian. Dari hasil penelitian diperoleh kesimpulan bahwa konsentrasi yang digunakan sebagai media peletakkan telur nyamuk Aedes aegypti akan mengganggu proses oviposisi pada nyamuk, semakin tinggi konsentrasi ekstrak daun sereh yang digunakan maka jumlah telur yang diletakkan semakin sedikit dan konsentrasi ekstrak daun sereh yang efektif mencegah peletakkan telur nyamuk Aedes aegypti pada konsentrasi 55%. Hal ini membuktikan bahwa sereh dapat digunakan sebagai antioviposisi atau penurunan aktivitas peletakkan telur nyamuk Aedes aegypti.
One of durian parts is its rind which contains essential oil, flavonoid, saponin, cellulose, lignin, as well as 11 starch content. Those content can be used as a larvacide against Aedes aegypti larvae. The aim of this research is to analysis LC50 of durian rind extract to mortality of Aedes aegypti larvae. In this research, we used the experimental method. Aedes agypti larvae are 440 larvae instar III divided into 12 groups which are negative control, positive control, durian rind extract with a concentration of 1%-10%. To identified the influence of durian rind extract to mortality of Aedes Aegypti larvae, data were analyzed using Probit Analysis with the program IBM SPSS Statistic 21.0. On the Probit Analysis, durian rind extract that could kill larvae 50% (LC50) is at concentration 7,76%. Based on that analysis, durian (Durio zibethinus murr) rind extract has an influence to mortality of Aedes aegypti larvae.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
