The effectiveness of activated carbon as adsorbent in the oil purification process fish by-product of the fish canning industry

Fish oil waste from the canning of low quality but can be recovered through purification processes correctly. Bleaching is a process to improve the color of the oil. The purpose of this study is to determine the effect of the use activated carbon to the effective characteristics and concentration on the fish oil purification byproduct of fish canning industry. This research method used is an experimental method using a completely randomized design (CRD) with five treatments with four replications. The concentrations used in this study is the treatment A (0 %), treatment B (2 %), treatment C (4 %), treatment D (6 %) and treatment E (8 %). The results showed that the addition of activated carbon adsorbent in the process of bleaching fish oil showed a highly significant (p <0.01) on levels of free fatty acids and significantly different (p <0.05) on the peroxide value. The highest level of free fatty acids is the treatment A (5.53%). The lowest level of free fatty acids is the treatment of B (1.68%). The highest value is peroxide of treatment E (110.35 meq/kg). The lowest level value is peroxide of treatment A (58.38 meq/kg).
