University riau Faculty of Agriculture. The purpose of this study was to determine the ability of AKR some extract concentration tuba (Derris elliptica Benth) to control the golden snail pest in rice plants. Treatments consisted of spraying the tuba root extract on rice plants with a concentration of 0 g / liter of water, 10 g / liter of water, 20 g / liter of water, 30 g / liter of water, 40 g / liter of water, and 50 g / Hter of water. Research carried out an experiment using a Completely Randomized Design (CRD) with 6 treatments and 4 rephcations. The results showed that the treatment tends to be more capable of killing 52.50% golden snail is a test of the treatment concentration tuba root extract 30 g / clumpen-USHama Keong EmasUR e-Research
