Fish oil by-product is generally of poor quality and therefore cannot be directly used, so it must be purification. Fish oil purification can be done by treatment centrifugation and addition adsorbent. The purpose of this study is to determine the best treatment addition adsorbent to improve the quality of fish oil. Fish oil purification is done by treatment using centrifugation and then adsorbed by the adsorbent. The lowest peroxide value on providing a combination of adsorbent attapulgite bentonite, amounting to 2.250 meq/kg. The lowest P-anisidine value on providing a combination of adsorbent attapulgite bentonite was 0.348 meq/kg. The lowest value of the total oxidation on addition adsorbent attapulgite bentonite combination of 4.848 meq/kg. Lowest value of free fatty acids in the addition of adsorbent attapulgite, bentonite and zeolite gradually, by 8.742%. The best transmission value obtained in combination treatment addition of synthetic adsorbents attapulgite and bentonite in fish oil first centrifuged.
