SIFAT ANTIRAYAP EKSTRAK KULIT BAWANG MERAH (ALLIUM CEPA L.) (ANTITERMITES PROPERTIES OF ONION SHELL EXTRACT)
ABSTRACT: The aims of these
researchs were to found the extract content of Allium cepa L., to evaluated
weight lost of paper disc, to evaluated the toxicity level of Allium cepa L.
extracts based on mortality rates and to evaluated feeding rate value. Research
was done by extracting a sample with methanol then partitioning with n-Hexane.
Extract with concentration of 2%, 4%, and 6% were used to test the toxicity of
extract for Coptotermes curvignathus termites. The results showed extract
content of Allium cepa L. was 16,62%. Termite mortality rate was 100% with
concentration 2% and 4% on day 7th while
the concentration of 6% on day 5th. So extract with the large concentration had
higher mortality of termite than the lower. The weight lost of paper disc was
around 3,72%–11,04% and feeding rate of termite was around 0,25 mg–0,73 mg.
Keywords: extract of Allium
