STUDI KOMPARATIF EFEK PENGGUNAAN PAKAN MANDIRI DAN PAKAN KOMERSIAL DALAM BUDIDAYA IKAN NILA SRIKANDI (Oreochromis aureus x O. niloticus) DI KABUPATEN BREBES, JAWA TENGAH

Penelitian ini bertujuan mengevaluasi penggunaan pakan mandiri dan pakan komersil untuk pakan ikan nila srikandi di Brebes, Jawa Tengah. Pemeliharaan ikan nila srikandi dilakukan menggunakan tambak yang berukuran ± 3.000 m2 sebanyak tiga unit di mana setiap petak tambak disekat menjadi dua sehingga terdapat enam unit petak percobaan. Setiap unit percobaan ditebar sebanyak 10.000 ekor benih ikan. Ikan nila srikandi dipelihara selama empat bulan dan diberi pakan harian sebanyak 1%-2% dari bobot tubuh pada pukul 07.00, 12.00, dan 17.00. Ikan diberi pakan uji pada bulan ke-1 dan ke-2 sebanyak 1% dari bobot tubuh, kemudian pemberian pakan ditingkatkan menjadi 2% pada pemeliharaan bulan ke-3 dan ke-4. Performa ikan nila srikandi (pertumbuhan, laju pertumbuhan, dan kelangsungan hidup) yang diberi pakan mandiri dan pakan komersil diuji dengan menggunakan uji-T. Hasil penelitian menunjukkan bahwa pertumbuhan ikan nila srikandi tidak berbeda nyata antara yang diberi pakan pakan mandiri dengan yang diberi pakan komersil (P>0,05). Kemudian, hasil produksi ikan nila srikandi yang diberi pakan mandiri mencapai 2.214 ± 172,69 kg dan pakan komersil 2.248,5 ± 234,85 kg. Berdasarkan hasil analisis usaha penggunaan pakan mandiri pada budidaya nila srikandi lebih direkomendasikan dibandingkan dengan pakan komersil.The purpose of this study was to determine the effects of locally-produced and commercial feeds on the growth of Srikandi tilapia cultured in fish farming areas of Brebes Regency, Central Java. Tilapia Srikandi were cultured in three ponds sized approximately ± 3,000 m2. Each pond was divided into two sections divided by a net, which resulted in six experimental plots. Each experimental plot was stocked with 10,000 fish seeds. Srikandi tilapia were maintained for four months and given daily feed as much as 1%-2% of body weight with feeding time at 07.00, 12.00, and 17.00. The fish were given test feeds in the 1st and 2nd month as much as 1% of body weight. The feeding level was increased to 2% in the 3rd and 4th months. The performances of Srikandi tilapia (growth, growth rate, and survival) fed with the two feed types were tested using the T-test. The results showed that there was no statistically significant difference on growth performance between fish fed with locally-produced feed and commercial feed (P>0.05). The total harvest of Srikandi tilapia fed with the locally produced feed reached 2,214 ± 172.69 kg and 2,248.5 ± 234.85 kg for the commercial feed. This study suggests that in terms of economic efficiency, the use of the locally-produced feed in Srikandi tilapia farming is more profitable compared to the use of commercial feed.
