For decades, fungi and insects namely ants and termites
had been a nuisance to human life. Therefore, we used
coconut fiber that is mixed with lemongrass essential oil
to replace wood products. Lemongrass essential oil is
usually used in oil treatments and insects repellent
products, not only because of its insecticidal effect, but
also due to its relaxing aroma and therapeutic benefits.
Therefore, recent studies on producing aromatic wood
products that can deduct insects away and prevent fungal
growth had been studied. Our target was to produce a
light, cheap and environmental friendly product that can
help in controlling fungi and insect’s problems. In this
study, we extracted the essential oil of lemongrass and
tested towards fungi (Aspergillus sp.). First method was
conducted by inoculating the fungi spores onto
Patatodextros medium (PDA) which was formerly put
onto the glass slip. Next, the fungi spores were spread
onto medium added with concentrated lemongrass
essential oil. Results show that the lemongrass is able to
control the fungal growth. Later, we tested the effect of
lemongrass essential oil on 30 ants and termites
respectively by placing two pieces of wood and coconut
fiber plates in different containers. One is drop with
lemongrass essential oil as manipulated variable, while
one is set as constant variable. The behaviour of the
termites and ants were observed within 5 minutes
intervals. As a result, the wood and the fiber plate
containing lemongrass essential oil were able to repel
ants and termites.
