"FORTIFIKASI MINYAK BUAH MERAH PANDANACEAE PADA PAKAN STANDAR TERHADAP PERTUMBUHAN DAN KUALITAS DAGING IKAN NILA GIFT (Oreochromis niloticus Bleeker) "

"Abstract This study aimed to know the levels of fatty acids, nutrition and the effect of treatment toward the growth rate in weight, daily body length, food conversion ratio (FCR), survival rate (SR) and feed efficiency (FE) of tilapia gift (Oreochromis niloticus Bleeker). Research methode used a complete randomized design with four treatments; P0=standard feed of T 78-2 series without red fruit oil (RFO) fortification, P1= standard feed of T 78-2 series with RFO 10 ml, P2= standard feed of T 78-2 series with RFO 15 ml, P3= standard feed of T 78-2 series with RFO 30 ml under three replicates. Analysis for fatty acids content was using Gas Chromatography – Mass Spectrometry (GC-MS). Results showed that saturated fatty acids content of tilapia gift (Orechromis niloticus Bleeker): P0: n-hexadecanoic acid 32.73%, Octadecanoic acid (ω-6) 0.80%, Methyl 2,4-dodecadienoate 0.35%, 7-Hexadecyne 10.08%, Tetracosanoic acid 9.71%, 1H-1,2,4- Tiazol-3-amine (3-amino-1,2,4-triazole) 0.61%, Dikoh lensaeure, ditert butyl ester 9.97% and Cis 10- Undecenoic acid 25.94%. P1: n-hexadecanoic acid 32.0112%, heptanoate 15.57%, Cyclohexane 0.57% and Cis 10-Undecenoic acid 19.32%. P2:n-hexadecanoic acid 38.35%, Dodecanal dimethyl acetal 3.58%, Nonanoic acid 0.89%, heptanoate 0.59%, Cyclohexane 2.83% and Cis 10-Undecenoic acid 30.70%. P3:nhexadecanoic acid 34.26%, 5-Octadecyne 0.42%, 1-(1,2-Epoxyethy-cyclohexane) 0.85%, 1,6-Heptadiene 0.7370%, Cis 10-Undecenoic acid 4.28%, Methyl 2,4-dodecadienoate 1.14%, Trans-nona-2,4-dienol (trans, cis-2,6-nonadienol) 0.39%. Essential fatty acids content of tilapia gift (Oreochromis niloticus Bleeker) showed that P0: Cis 13-Docosenoic acid 1.32 %; P1: Cis 9-Octadecenoic acid (ω-6) 24.56 %, 9- Octadecenoic acid (ω-6) 1.54 %, Octadecenoic acid (ω-6) 19.32 %, Cis 11,14- Eicosadienoic acid 4.70 %, Cis 15-Tetracosenoic acid 1.81 %. P2: Cis 9,12- Octadecenoic acid (ω-6) 7.32 %. P3: Octadecanoic acid (ω-6) 1.40 %, Tetracosanoic acid 0.49 %, Cis 15-Tetracosanoic acid 2.20 %, Cis 9-Octadecenoic acid (ω-6) 1.65 %, Cis 9,12-Octadecadecenoic acid (ω-9) 18.86 %, Cis 7,10,13-Eicosatrienoic acid 0.50%. Nutritional content of tilapia GIFT (Oreochromis niloticus Bleeker): highest protein content at P2 11.86% and the lowest at P1 6.55%. The highest fat content was at P1 1.30% and the lowest was at P0 0.74%. The highest carbohydrate content was at P1 13.16% and the lowest was P2 7.09%. The highest water content was at P0 80.24 % and the lowest was P3 77.26%. The highest ash content was P3 1.68% and the lowest was P0 1.44% . The mean rate of weight gain and daily weight gain (specific growth rate, SGR): P0 (2.20±0.05) g/day, P1 (2.55±0.12) g/day, P2 (2.37±0.30) g/day and P3 (2.31±0.02) g/day. Overall, P1 was more influential and the appropriate dose of P2 to increase growth was 15.60 – 16.50 mL of RFO Pandanus austrosinensis.
