There are so many consumers and small scale traders of fried food in this world, including Indonesia. Unfortunately, some of the traders usually do not have enough capital to create a good healthy standard for the food they produced and therefore they use their cooking oil (usually called waste cooking oil) repeatedly more than 8-10 times. Obviously the oil is not a good healthy standard for producing food. Useless materials in the waste oil especially peroxide will increase risks of some diseases, such as cancer. This research conducted to test the effectiveness of banana peel as readily available, low cost, environment friendly bio-material. The banana peel could adsorb peroxide and increase the brightness of waste cooking oil. Several 100 ml samples of waste cooking oil were treated at room temperature using combinations of 2 grams of dehydrated banana peel, activated carbon banana peel, carbon banana peel, and/or shallot, and compared to commercial activated carbon as absorbent. After 24 hours, the concentration of peroxide (peroxide number) was calculated using a thiosulphate titration method. Clarity, thus purity of each samples were also compared by analysing the absorbance using a spectrophotometer. The result shows that dehydrated banana peel is the best material applied to remove peroxide in waste cooking oil compared to activated carbon banana peel, carbon banana peel, shallot, and commercial activated carbon. Whereas shallot is the material that results in the brightest waste cooking oil compared to other material used.
