In this study using Tawes fish with length berween 4-6 cm.In this toxicity test is done in 2 stages, namely : range finding test, the search for this range is obtaind 0% consentrations (as control) 0,3%; 0,6%; 0,9%; 0,12% and 0,15%. The next stage of toxicity acute test, at this stage of toxicity consentration do smaller again that is : 0,18%; 0,36%; 0,54%; 0,72% and 0,9%.The results obtained LC50 value of 0,385%, while eyes, brown stomach skin.
