Caterpillar of Grayak (Spodoptera Litura F.) representing very pest met many in agriculture, because in character which is polifag (eating crop type) so that can destroy various agriculture crop type like paddy, maize, soy, bean, tomato, and vegetable. At the moment the effort prevention and overcoming damage of crop by Spodoptera litura F. still using many sintetis insektisida, usage of sintetis insektisida alone very harming once to creature of hiup exist in vinicity and also to environment. Exploiting of crop as producer of active materials vegetation insektisida represent one of the alternative which can lessen damage of environment and is not dangerous to mortal around, one of them red ginger rimpang (Zingiber Officinale Rosc.). This research aim to to know influence giving of water extort of red ginger rimpang (Zingiber Officinale Rosc.) to caterpillar mortalitas of grayak (Litura F Spodoptera.), and also to know at concentration how much water perasan of red ginger rimpang ( Zingiber Officinale Rosc.) effective to caterpillar mortalitas of grayak ( Litura F Spodoptera.). This research executed on 17-19 January 2008 in Chemical Laboratory of UMM. Sampel the used is caterpillar of grayak ( Litura F Spodoptera.) III instar amount to 480 obtained tail of BALITAS Malang. this Method Research use RAL ( Complete Random Device) by 6 treatment and 4 times restating. Concentration level the used is 0% (control), 15%,25%,35%,45%, and 50%. Parameter perceived the amount of caterpillar mortalitas of grayak ( Litura F Spodoptera.) during 3 day. Data result of this research is analysed to use one way anava and continued with test of duncan 5%. Result of data analysis indicate that there is real influence giving of water extort of red ginger rimpang ( Zingiber Officinale Rosc.) to caterpillar mortalitas of grayak (Litura F Spodoptera.) in so many concentration. effective concentration in this research is water extort of red ginger rimpang (Zingiber Officinale Rosc.) with concentration 35% while most having an effect on concentration is 50%.
