Abstract

The study was conducted on March, 18th -May, 2nd 2014 at Balai Benih Ikan Keumala, Pidie Regency, Nangroe Aceh Darussalam Province. The aim of this study was to test the use of willow leaf powder in the feed to reduce fertility levels of gift tilapia (Oreochromis sp. genetic improvement farmed tilapias ). The method in this study used non-factorial completely randomized design with four treatments and three replications i.e. A: without giving willow leaf powder, B: 40 mg, C: 50 mg, D: 60 mg leaf powder. The results showed that the application of willow leaf powder in the fish feed gives a very significant effect on the level of fertility and hatching rate of tilapia, where (F value > F table). The eggs were unfertilized on the treatment numbers D, C, and B, meanwhile almost of eggs were fertilized in the treatment numbers A (without giving willow leaf powder). Otherwise, the results showed that the willow leaf powder was not affect the growth weight and length of tilapia (Fvalue < Ftable). Abstrak Penelitian ini dilaksanakan pada tanggal 18 Maret-2 Mei 2014 di Balai Benih Ikan Keumala, Kabupaten Pidie, Pro-vinsi Nangroe Aceh Darussalam. Tujuan penelitian untuk menguji penggunaan tepung daun gandarusa dalam pakan un-tuk mengurangi tingkat fertilitas pada ikan nila gift (Oreochromis sp., genetic improvement farmed tilapias). Metode yang digunakan pada penelitian ini adalah rancangan acak lengkap non faktorial dengan empat perlakuan dan tiga ulangan yaitu perlakuan A: tanpa pemberian tepung daun gandarusa, perlakuan B: 40 mg, perlakuan C: 50 mg dan perlakuan D: 60 mg tepung daun gandarusa. Hasil penelitian menunjukkan bahwa pencampuran tepung daun gandarusa dalam pakan memberi pengaruh yang sangat berbeda nyata terhadap tingkat fertilitas dan tingkat penetasan telur ikan nila gift. Telur yang paling banyak tidak terbuahi adalah pada perlakuan D kemudian C, dan B, sedangkan yang paling banyak terbuahi adalah pada perlakuan A. Hasil penelitian ini juga menunjukkan bahwa tepung daun gandarusa tidak memberi pengaruh buruk terhadap pertumbuhan baik pertumbuhan bobot maupun panjang ikan nila gift (Fhitung < Ftabel).
