Abstract

Beluntas (Pluchea indica)merupakan tumbuhan yang belum dimanfaatkan. Beluntas adalah tumbuhan yang memiliki kandungan senyawa metabolit sekunder, antara lain tannin, alkanoid, flavonoid, minyak atsiri dan saponin. Senyawa tersebut dapat memberikan efek toksik terhadap hama. Penelitian ini bertujuan untuk mengetahui pengaruh dan besar konsentrasi ekstrak daun beluntas terhadap mortalitas dan perkembangan S. litura F. Metode yang digunakan dalam penelitian ini adalah metode maserasi dan leaf dipping pada pakan dengan jumlah ulangan tiap konsentrasi sebanyak tiga kali. Metode analisis data yang digunakan yakni Uji One Way Anova dengan taraf kepercayaan 95% dan analiasa probit. Parameter yang diamati adalah mortalitas dan pembentukan pupa. Ekstrak daun beluntas berpotensi sebagai insektisida nabati. Konsentrasi ekstrak kontrol, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, dan 90% pada perlakuan 24 jam mampu memperoleh nilai LC50 sebesar 28% dan menunjukkan beda. ===================================================================================================== Beluntas (Pluchea indica) is a plant that has not been utilized. Beluntas are plants that contain secondary metabolites, such as tannins, alkanoid, flavonoids, essential oils and saponins. The compound can give toxic effects against pests. This research aims to determine the effect and concentration of beluntas leaf extract on mortality and development of S. litura F. The method used in this research is the maceration method and leaf dipping on the feed with number of replications for each concentration is three times. Methods of data analysis used is One Way Anova test with 95% confidence level and probit analysis. Parameters measured were mortality and pupa formation. Beluntas leaf extract has potential as a plant-based insecticide. Control extract concentration, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, and 90% at 24 hours treatment are able to obtain LC50 values of 28%. So it can affect the development by inhibiting the formation of the pupa.
