Andragogy Approach in the Utilization of Liquid Smoke Coconut Waste as a Vegetable Insecticide for Coconut Farming Community

Abstract

Appropriate technology learning must be able to touch all levels of society.
In this research, we combine formal education with informal education in
the form of participatory education for adults. Participatory education is
intended to involve the community directly participating in the
implementation of this research by seeing, doing, and observing the process.
The aim is how to utilize liquid smoke from coconut frond waste as a
vegetable insecticide as well as a repellent or insect repellent because it
contains phenol or phenolic, antioxidant, antimicrobial in coconut plants in
the people of Aceh Besar. Based on the results of chemical analysis in liquid
smoke found elements or chemical substances, such as acetic acid, carboxyl
and phenol. This study aims to determine how the effect of temperature and
duration of combustion on the yield (final product), such as the degree of
acidity, acetic acid content, and phenol content. This research was carried
out using a factorial Completely Randomized Design (CRD) with two main
factors, namely: Factor-1 burning for 2-3 hours and Factor-2 with variations
in temperature 200oC, 250oC, 300oC, 350oC, 400oC. The best result for
liquid smoke is 25% (w/w) of 20 kg of dry matter from coconut fronds. The
average content of acetic acid (CH3COOH) is 6.45 mg/ml. And the content
of phenol (C6H6O) is 3.76 ppm.
