plants by the nature of saga seed husk (Adenanthera pavonina L). This
research aimed to know saga seed husk extract rate and percentage of
heavy degradation of test example, level toxic of shallot husk extract
based on value of mortality and termites consumption level value.
Research done by extracting sample with methanol and partitioned with
n-Hexane. Concentrated extract 2%, 4%, and 6% was used the toxicity test
of the termite Coptotermes curvignathus.
The Results showed that saga seed husk extract content is 15.82%.
Mortality of termite baiting with 6% concentration was happened in the
day of 5 respectively, mortality in 2% and 4% was happened in the day 6
while the control concentration was happened in the day of 12. There was
tendency of saga seed husk extract concentration excelsior hence
progressively /repository.usu.ac.id/handle/123456789/33603lower the
percentage lost weight of cellulose paper and rate of consumption of
termites.
The percentage lost weight of cellulose paper about 3,88%–11,04%,
mortality rate on different concentration reach 100 % and rate of
consumption of termite is 0,26–0,73mg. Thereby concentration 6% was
better evaluated from mortality, the percentage lost weight of cellulose
paper and rate of consumption of termites.
