TOKSISITAS CAMPURAN EKSTRAK DAUN PLETEKAN (Ruellia tuberosa L.) DAN DAUN SIRSAK (Annona muricata L.) TERHADAP LARVA NYAMUK Aedes aegypti DAN PEMANFAATANNYA SEBAGAI BUKU ILMIAH POPULER

Abstract

Aedes aegypti L. is the primaty vector for Dengue Hemorrhagic Fever. Since synthetic insecticidies poes environmental risk, exploring eco-friendly alternatives like combined extracts of pletekan (Ruellia tuberosa) leaves and soursop (Annona muricata) leaves is essensial. This study aimed to evaluated the larvicidal toxicity of this combination and develop the findings into a popular scientific book. This experimental research followed a Completely Randomsizec Design (CRD). Larvae were exposed to five concentrations (75,150, 300, 600, and 1200 ppm) with four replicants. Mortality was recorded after 48 hours and analyzed using probit analysis to determine the LC50 value. The findings demonstrated that the combined extract significantly increased larva mortality. The calculated LC50 value was 261,442 ppm (95% Cl: 175.406 – 340.227 ppm). Furthermore the developed populer scientific book was categorized “Highly Feasible” based on expert validation. The synergistic combination of pletekan (Ruellia tuberosa) and soursop (Annona muricata) leaves is a potent natural biolarvacide. Moreover, the resulting popular scientific book serves as a valid and affective educational medium or community based mosquito control.
