Abstract

The cultivation of Tilapia (Oreochromis niloticus) has the prospect to be developed with high economic value. One of the obstacles in tilapia cultivation is the attack of Pseudomonas aeruginosa. One of the effort to prevent bacteria disease which do not cause a negative impact on fish, the environment, or consumers that is the use of natural materials such as the utilization of coconut shell that has been processed into liquid smoke. Liquid smoke of coconut shell have bioactive compounds such as phenol, carbonyl and organic acids that act as antibacterials. The result of this research shows the effect of giving of liquid smoke in commercial feed for 21 days maintenance can give effect to total Pseudomonas aeruginosa on Tilapia fish kidney organ. 1.5% concentration in commercial feed is an effective concentration for the total decrease of Pseudomonas aeruginosa in tilapia kidney organ. Total Plate Count (TPC) value at concentration of 1.5% is 1.80 x 104 CFU/g.
