PENGUJIAN AKTIVITAS LARVASIDA EKSTRAK ETANOL KULIT BAWANG PUTIH (ALLIUM SATIVUM L.) TERHADAP MORTALITAS LARVA AEDES AEGYPTI

Abstract

Aedes aegypti is the primary vector of dengue fever (DF), which poses a significant public health problem. This study aimed to evaluate the larvicidal activity of ethanol extract from garlic peel (Allium sativum L.) and to analyze the effect of concentration variation on larval mortality. The extract was obtained using a reflux method with 70% ethanol as the solvent. The study was conducted experimentally in the laboratory by exposing third instar larvae to various extract concentrations. Larval mortality was analyzed using probit analysis to determine LC90  and LT90  values. The results showed that the ethanol extract of garlic peel exhibited larvicidal activity, with larval mortality increasing in line with higher extract concentrations. LC90  and LT90 values indicate the effectivenes of the extract as a larvicide. These findings suggest that garlic peel has the potential to be a safe and sustainable plant-based alternative for controlling Aedes aegypti vectors.
