Abstract

Insecticidal efficacy of Lantana camara is affected by the efficacy of formulation used determined by the concentration of its bioactive compound. The use of Bacillus thuringiensis (Bt) could induce the fermentation of L. camara and the selection of compatible solvent might contribute in production of its bioactive compound. This study was aimed to evaluate the effect of B. thuringiensis-induced carrier composition and solvent types on the yield of L. camara bioactive compounds. This study was conducted using completely randomized design consisting of two separately performed assays, namely evaluation of Bt-induced carrier composition and evaluation of solvent types. Assessment of carrier composition consisted of five treatments, such as (1) Bt with POME (palm oil mill effluent), (2) Bt with POME: coconut water (1:3), (3) Bt with POME: coconut water (1:1), (4) Bt with POME: coconut water (3:1) and (5) Bt with coconut water. Extraction of L. camara bioactive compound was further evaluated through solid extraction with various types of solvent, such as methanol, ethanol and acetone. During the fermentation of L. camara with all Bt-induced carrier compositions, significant pH drop was recorded after six days without any remarkable temperature change. From the solid extraction, the highest yield of bioactive compounds (15%) was produced by L. camara fermented in Bt with POME: coconut water (1:1) and extracted with acetone.
