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