Uji Konsentrasi Ekstrak Daun Sungkai (Peronema Canescens Jack) Berpelarut Organik Terhadap Mortalitas Ulat Bawang (Spodoptera Exigua Hubner) Di Laboratorium

---

ABSTRACT
Shallot plants (Allium ascalonicum Linn.) are widely used in cooking and traditional medicine. However, production in Riau Province is unstable, partly due to pest attacks, especially S. exigua, which damages leaves and reduces yield. Botanical pesticides are recommended for control to avoid the negative effects of chemical pesticides.One potential plant for botanical pesticide production is sungkai (Peronema canescens Jack). This study aimed to evaluate the effectiveness of various concentrations of sungkai leaf extract on S. exigua larval mortality. The experiment used a completely randomized design with six treatments (0%, 0.2%, 0.4%, 0.6%, 0.8%, and 1%) and four replications. Each unit contained 10 third-instar larvae, treated via spraying.Parameters observed included time to first death, daily and total mortality, LT₅₀, LC₅₀, LC₉₅, temperature, and humidity. Data were analyzed descriptively and statistically (ANOVA and probit analysis). Results showed that 1% sungkai extract was most effective, causing 82.5% mortality within 48 hours (LT₅₀), with the first death occurring 8 hours after treatment.
Keywords : Botanical Insecticide, Sungkai Leaf Extract, S. exigua, Shallot (Allium ascalonicum), Sustainable agriculture.
