Optimization of cultivation through input protein-energy efficient in the diet is very urgent. Fish need fat as an energy source and to maintain the shape and function of membrane tissue. This study aims to explore source fat from alternative materials of animal fat (caterpillar flour or larvae of Tenebrio molitor) and seed fat (hazelnut) in the form of feed oil supplement (FOS) its impact on feed efficiency and protein efficiency ratio in red tilapia fish seed phase. Methods of extraction descriptively, followed by a biological test experimentally, completely randomized design (7x3) use of feed oil supplement from caterpillar flour and hazenut (each with a dossage 1%, 2% and 2% a mixture of both) were added to the basal feed (low protein), and treatment standard feed (high protein). The extraction of hazelnut (31.72% crude protein, fat 35.32%) and the caterpillar flour (crude protein 55.11%; 15.51% fat), obtained the total yield of 30-35% material and extract oil supplements each 9.9 % and 4.05% initial weight. Biological test showed that the highest feed efficiency in the use of 2% a mixture of both caterpilar and hazelnut oil, but not significatly different with the use of standard feed and 2% hazelnut oil and caterpillar oil. Feed efficiency and Protein efficiency ratio of 2% feed oil supplement was higher compared to 1% feed oil supplement award and the basal feed. The addition of feed oil supplement will be increasing content of Energy-Protein Balance in the feed (ranging from 6.8 to 8.9 kcal.g-1 protein). There means the protein sparring effect (effect of partial substitution of protein as an energy sources by fat) so as to conserve resources N and in turn be able to eliminate the discharge of nitrogen in the water
