Noni fruit is one of the plant that be rich of antioxidant. 50 gram simplisia of noni added to 250 ml waste cooking oil of packadge and bulk oil. The methods of acid number by alkalimetri and measurement of water content using oven. The organoleptic tests carried out by favorite level from 25 panelists. The results of this research showed that persentage of reduction in packpage and bulk oil’s acid number were 28% and 25%. Whereas for persentage of reduction water content from each oil were 75% and 71.42%. The favorite level of color, odor and flavor were 99%, 76% and 89%.
