THE PERFORMANCE OF Litsea angulata ESSENTIAL OIL FOR ANTI TERMITE ACTIVITY AGAINST SUBTERRANEAN TERMITES (Macrotermes gilvus)

Abstract

. Litsea angulata from the Lauraceae Family is an aromatic plant that can produce essential oils from the forests of East Kalimantan, Indonesia. Aromatic plants can be toxic to insect pests, including termites, and can be used as an environmentally friendly alternative for anti-termite bioactivity. This research aims to determine the characteristics of essential oils of L. angulata leaves produced and their potential bioactivity to subterranean termites (Macrotermes gilvus). Essential oils are distilled by water and steam distillation method. The oil collected was the result of a 1-hour distillation process and yielded 0.32%. The results of the GC-MS identification show that the chemical components of the oil fraction of L. angulata are dominated by terpenoid compounds, with 3 major compounds, which are the main compounds, including Camphor, α-Phellandrene and α-Pinene. Bioactivity of anti termite was tested using a modified bioassay antifeedant method with a concentration variation of 0% (negative control), 5%, 10%, 15%, 20%, 25%, and fipronil 0,25% (positive control). The abundance of terpenoid group compounds is thought to have a great effect on anti-termite activity, with the quite strong effectiveness of L. angulata oil, with a percentage mortality rate ranging from 81-84%.
