Rice is a main food for 2/3 population in this world. The process of rice has a by product is rice bran. Rice bran content 16-23 % weight of oil. Rice bran oil is one of kind of oil that has high nutrient because that oil has fatty acid, biological active components and anti oxidant component. For this research, we did rice bran oil extraction and then degumming process and the last bleaching process using adsorbent active carbon. From the bleaching of rice bran oil, we get the best time is 40 min, the mixing velocity is 300 rpm, the temperature is 100  oC, and active carbon mass is 0,5 gram.
