SIFAT ANTIRAYAP EKSTRAK KULIT BIJI SAGA

(Adenanthera pavonina Linn)

ABSTRACT

         The aims of research were to know the extract content of saga seed shell, to evaluated weight lost of cellulose paper, to evaluated mortality of termites and to evaluated termites consumption. Research was done by extracting sample with methanol then partitioning with n-hexane. Concentrated extractive  of 2%, 4%, and 6% were used the toxic test of the Coptotermes curvignathus termite. The results showed that extract content  of saga seed shell was 15.82%. Mortality with concentration of 2%, 4% and 6% were not significantly. So the concentration of 2% was effective, eficien and happened in 6^th day. The tendency showed that increasing concentration of extract caused decreasing of weight lost of cellulose paper and consumption of termites. The percentage weight lost of cellulose paper was 3.88%–11.04% and consumption of termite was 0.26–0.73 mg. The extract with concentration of 2% was effective based of evaluated from mortality, weight lost of cellulose paper and rate consumption of termites.
