<p align="center"><strong>ABSTRAK</strong></p><p>Budidaya ikan nila <em>(Oreochromis niloticus) </em>terus dikembangkan hingga saat ini. Berbagai teknologi dalam bidang perikanan telah diterapkan, salah satunya yaitu <em>sex reversal </em>dalam hal ini jantanisasi. Ikan nila jantan lebih cepat pertumbuhannya dari pada ikan nila betina sehingga dapat meningkatkan hasil produksi. Tujuan penelitian ini yaitu untuk mengetahui pengaruh pemberian tepung testis sapi dan dosis terbaik tepung testis sapi dalam pakan yang mengandung  rGH terhadap rasio jenis kelamin, pertumbuhan dan kelulushidupan ikan nila. Bahan uji yang digunakan adalah larva ikan nila dengan stadia larva yang berumur 7 hari setelah lepas kuning telur dan memiliki bobot rata-rata 0,07 gram/ekor. Penelitian ini menggunakan metode eksperimental dengan Rancangan Acak Lengkap 4 perlakuan dan 3 kali ulangan. Perlakuan dalam penelitian ini yaitu dengan menambahkan tepung testis sapi dengan dosis pada perlakuan A (0%/kg pakan), perlakuan B (3%/kg pakan), perlakuan C (6%/kg pakan) dan, perlakuan D (9%/kg pakan). Pakan pada setiap perlakuan dalam penelitian ini telah ditambahkan rGH dengan dosis 2 mg/kg pakan. Data yang diamati meliputi rasio jenis kelamin, laju pertumbuhan spesifik (SGR), dan tingkat kelulushidupan (SR) ikan nila<em>.</em> Hasil penelitian menunjukan bahwa perlakuan C (6% tepung testis sapi/kg pakan) memberikan hasil terbaik dimana nilai rasio jenis kelamin jantan sebesar 74,44±5,09% dan laju pertumbuhan spesifik sebesar 9,48±0,10% bobot/hari. Kesimpulan yang diperoleh dalam penelitian ini yaitu adanya pengaruh nyata terhadap rasio jenis kelamin dan tingkat pertumbuhan spesifik, namun tidak berpengaruh nyata terhadap tingkat kelulushidupan ikan nila dengan pemberian dosis tepung testis sapi terbaik adalah 6% tepung testis sapi/kg pakan.</p><p><strong>Kata kunci: </strong>Sex reversal; Tepung testis sapi;  Pertumbuhan, rGH; Nila<strong></strong></p><p align="center"><strong>ABSTRACT</strong></p><p><em>Tilapia fish (Oreochromis niloticus)cultivation still continue to be developed until nowdays. Many fisheries technology had been applied, and one of them is sex reversal which is masculinization. Male tilapia fish grows faster than the female one, so this can boost the produce of the fish. This research aims to know the effect of cow testicle flour addition and determine the best dosage on the fish feed which contains rGH towards the male-sex ratio, growth, and survival rate of tilapia fish. The material which used in this research was tilapia fish (O. niloticus) which under the larvae phase 7 days post the separated egg yolk which have average weight of 0,07 grams/each. This research used experimental methods with Completely Randomized Design of 4 treatments and 3 times of repetitions. The treatments in this research was addition of  different dosage of bull testicle which treatment A (0%/kg fish feed),treatment B (3%/kg fish feed), treatment C (6%/kg fish feed) and, treatment D (9%/kg fish feed). The fish feed in every treatment had been added with 2mg rGH/kg fish feed. Data observation  during this research were male-sex ratio, specific growth rate (SGR), and survival rate (SR) of tilapia fish. Results of the research showed that treatment C (6%/kg fish feed) gave the best result as male-sex ratio by 74,44±5,09% and specific growth rate by 9,48±0,10% weight/day. Conclusion obtained from this research was: there was different result  towards the male-sex ratio and specific growth rate, but there was no difference between the treatments towards the survival rate, the best bull testicle flour dosage was 6%/kg fish feed. </em></p><p><strong><em>Keywords:</em></strong><em> Sex reversal, Bull testicle flour, Growth, rGH, Tilapia<strong></strong></em></p>

Tilapia (Oreochromis niloticus) has economic value due to high consumer demand, relatively affordable price, favorable taste and high tolerance to the environment. Constraints faced by farmers is the high feed prices because raw materials such as fish meal is still imported. So need to find alternative raw materials such as golden snail flour which has a cheap price. The purpose of this study is to analyze the proportion of the right golden snail flour in the fish feed so as to provide maximum growth rate for the seeds of tilapia gift. The experimental design used was Completely Randomized Design (RAL) consisting of 5 treatments with 3 replications. The parameters observed were growth rate and feed efficiency. The experimental results showed that the C treatment (0.19 g/day) was the highest growth rate and the highest feed efficiency in treatment C was 88.03%. Keywords: tilapia, mas snail flour, growth rate, and feed efficiency Abstrak Ikan nila (Oreochromis niloticus) memiliki nilai ekonomis karena permintaan konsumen yang tinggi, harga yang relatif terjangkau, rasa yang digemari dan memiliki toleransi yang tinggi terhadap lingkungan. Kendala yang dihadapi petani adalah harga pakan yang tinggi karena bahan baku seperti tepung ikan masih di impor. Maka perlu mencari bahan baku alternatif seperti tepung keong mas yang memiliki harga yang murah.Tujuan penelitian ini adalah menganalisis proporsi tepung keong mas yang tepat dalam pakan ikan sehingga mampu memberikan laju pertumbuhan yang maksimal bagi benih ikan nila gift. Rancangan percobaan yang digunakan ialah Rancangan Acak Lengkap (RAL) yang terdiri dari 5 perlakuan dengan 3 ulangan. Parameter yang diamati adalah laju pertumbuhan dan efisiensi pakan. Hasil percobaan menunjukkan bahwa perlakuan C (0,19 g/hari) merupakan laju pertumbuhan yang tertinggi dan efesiensi pakan tertinggi pada perlakuan C yaitu 88,03 %.

Tilapia (Oreochromis niloticus) has been gaining ground in cultivation and sale in Bangladesh but due to price hike of fish feed the culture of this fish faced many challenges. In the present study, the optimal level of dietary moringa (Moringa oleifera) leaf powder was used as feed supplement to determine the growth performances, some selective blood parameters and bacterial load in Nile tilapia, Oreochromis niloticus. Commercial diet containing moringa leaf powder at 0g/kg, 100g/kg and 200 g/kg diet was used. The diet containing 100g moringa leaf/kg diet resulted in increased weight gain, average daily gain, specific growth rate, condition factor and survival rate. A significant (p<0.05) reduction in RBC and WBC were found as the moringa leaf inclusion increased in the diets but no significant (p<0.05) differences were observed among the three different rearing conditions. In most of the cases, the diet containing 100g moringa leaf powder/kg diet displayed lower amount of bacterial count but no significant improvement was found in bacterial load among the different treatment conditions. The results suggest that dietary moringa leaf powder could be included in the diet of Nile tilapia at possibly not over 100 g/kg diet for the betterment of growth, survival, immune response and microbial challenge.
