Abstract

Despite the abundance of palm-based residues generated the by-products from thermochemical processing such as bio-oil may create value-added products to the palm industry. The palm-based derived bio-oil contains high aromatic compounds which are active ingredients in the bio-pesticides formulation. Therefore this study investigated the formulation of the bio-pesticide from this bio-oil and determines their effect on insect-pest in oil palm such as Metisa plana walker bagworm. Prior the formulation preliminary evaluation of the compatibility between bio-oil and surfactants such as Tween 20 and Tween 80 as the bio-pesticides ingredient were evaluated using the ternary phase diagram. The compatibility results showed the best formulation is at 20 of surfactant. Based on these conditions the experiment was formulated using an active ingredient (AI) called azadirachtin extracted from neem seed. The formulated bio-pesticide was tested for its effectiveness towards the mortality of the bagworm. The results showed that the formulated bio-pesticide was able to repel 50 of the bagworm population with a lethal concentration (LC50) of 22.1 g/mL showing a good indicator as an effective repellent. Hence this study provided new knowledge for waste management towards zero waste strategy for a better environment and sustainability.
