Drywood termites of Cryptotermes cynocephalus Light are a very dangerous type of destructive insect. The attack was very broad, covering all components of a house made of wood. Besides that, the use of wood with high durability is increasingly scarce, this is due to the decreasing supply of wood that has high durability from natural forests and the price is expensive. As a consequence, buildings tend to use wood that has low durability so that it is very susceptible to termite attacks.

Termite control become an indispensable treatment for protecting buildings. It means anti-termite chemicals are still very needed. Testing methods refer to the Indonesian National Standard, SNI 01-7207-2006, by using the forced-feeding test method. Wood measuring 2 x 2 x 1 cm will be tested first at a temperature at 600 ° C for 3 days to find out its weight. The sample to be tested is 2 cm x 2 cm x 1 cm along with 50 termites of dry wood termite workers Cryptotermes cynocephalus Light is inserted into a 4 x 4 x 4 cm glass box. The observed data were the percentage of weight loss and termite mortality. Observations are made every week for six weeks.

Weight loss percentage = (ODW1-ODW2) / ODW1 X 100%
Where:
ODW1: Dry weight of the sample oven before termite testing
ODW2: Dry weight of the sample oven after testing.
Mortality percentage = (R1-R2) / R1 x 100%,
Where:
R1: Number of termites before testing
R2; Number of termites that live at the time of observation

In Figure 8 it can be seen that treated wood samples have an average weight loss (weight loss) far below 2%. Whereas untreated wood has a percentage of weight loss above 2% so we say that the treated wood is very resistant to attack by dry wood termites (fulfilling SNI).

In Figure 9, it can be seen that the treated wood causes 100% dry wood termites to die on the second day, while only 17% of untreated wood at the end of the test. This indicates that the chemicals used are very effective in protecting wood from attacks by dry wood termites.
