The purpose of this study was to determine the level and the ratio of types of vegetable fat supplements that are effective in improving the quality of pellets and growth of tilapia, with the following stages:1) Preliminary test to determine fat level, 2) The extraction of vegetable fats (hazelnuts and coconuts) was then formulated with saturated and unsaturated fatty ratios in pellets at the same fat level, and tested their physical qualities by measuring the stability of fish pellets, 3) Feeding trial of saturated fat sources (coconut extract) compared with unsaturated fats (hazelnut extract) in the formulation of growth and efficiency of tilapia seed feed. The experiment was designed completely randomly (5x3) with the treatment of saturated and unsaturated fatty ratios in low protein feed as follows: (1) basal / no oil feed, (2) coconut oil without combination with hazelnut (1: 0); (3) coconut oil mixture and hazelnut (1: 1), (4)hazelnut oil (0: 1), (5) feed control. Chemical analysis results were tested descriptively, while performance data (growth) were analyzed by variety and the difference between treatments was tested with Duncan analysis. Preliminary test results indicate that the use of 4 percent fat level can be used in the formulation of tilapia feed and in accordance with the needs of optimum fats. Chemical description of unsaturated fat sources (linoleic) in hazelnut meets the nutrient requirements of nirvana Nile seed phase. The results of test of water stability obtained that 4% vegetable fat supplement and can improve the physical quality of pellets; with stability (77.57-80.49%) after two hours. The feeding trial showed that the mixture of coconut and hazelnut fat supplements of 2% each in pellet produced physical quality, growth (daily growth rate and specific growth rate) for Nile Nirvana fish. The results of this study indicate that the ratio of saturated 1: 1 unsaturated fats from vegetable oil sources, can match the growth and efficiency achievement of fish fed with higher protein / containing ω-3.
