ABSTRACT               Masculinization is a method of  sex reversal technique that can direct sexuality from female to male. The purpose of this study was to determine the effects of coconut water on masculinization in guppy by immersion administration. The study used a completely randomized design (CRD) with three treatments and three replications. After 12 days post spawning, female guppies were immersed for 8 hours.The concentrations were : 0%(P0), 20% (P1), and 40% (P2). The parameters were observed including percentage of male, survival rate and water quality (thermal, pH and kalium concentration). Baby guppies were reared until sex can be determined which were 42 days of culture. The result showed that the percentage of male guppy fish was 54.44% (P0), 77.78% (P1) and 90.00% (P2). The survival rate of  larval during maintenance was 100% for all treatments. Water quality during maintenance was 27.0-28.40C for temperature and 6.38-7.20 for pH. To sum up, this experiment proved that coconut water can be used for masculinization by immersed pregnant female broadstock and it produced 90% male when immersed with 40% of coconut water. Keywords : Coconut water, guppy (Poecilia reticulata), masculinization

Menggunakan metode eksperimental dan Rancangan penelitian yang digunakan Rancangan Acak Lengkap (RAL) non faktorial dengan 4 perlakuan dan 3 ulangan. Hasil penelitian menunjukkan bahwa Pengaruh lama perendaman yang Berbeda menunjukkan hasil yang berbeda nyata terhadap keberhasilan jenis kelamin jantan ikan guppy. Dengan hasil perlakuan yang terbaik terdapat pada perlakuan C dengan perendaman 15 jam dengan jumlah rata-rata 89.93%. Sedangkan yang terendah terdapat pada perlakuan (A) perendaman 9 jam yaitu (72.32%). Saran Perlu adanya penelitian lanjutan mengenai jantanisasi dengan menggunakan madu dilakukan dengan dosis yang lebih tinggi dan waktu pemaparan singkat, serta perlu di lakukan penelitian mengenai kemampuan ikan guppy untuk menyerap madu yang di berikan.This study aimed to get the best immersion time for the guppy brood fish (Poecilia reticulate). The research was conducted in November 2014 until January 2015 which was held at the Laboratory of Aquaculture Hatchery and Technology, Faculty of Agriculture, University of Malikussaleh. The method of this study wos experimental menthod and analysis used completely randomized design (CRD) with 4 treatments and 3 replications. The results showed that the soaking time influenced significantly to the success of the male sex of guppy fish. The best treatment of soaking time was a 15- hours immersion with the male ratio 89.93%. While the lowest one was obtaimed in treatment of 9 hours immersion which was of (72.32%) of male. Range Value of water quality parameters during the study, namely the temperature was 26.4 - 28. 0 ° C, pH between 6.5 -8.0.

Guppy fish Poecilia reticulata is one of the most popular freshwater ornamental fish species because it is easy to main-tain, and has beautiful variations of color, especially males. One method to produce male guppy is masculinization me-thod. This study aimed to determine the dose of hormone treatment from visceral organ of sea cucumber to the process masculinization of fish guppy. This study used a completely randomized design with the immersion treatment of parent guppy which has been bred into the extract solution of sea cucumber innards for 24 hours with different doses i.e. 0 mg L-1, 10 mg L-1, 20 mg L-1, 30 mg L-1 and 22 mg L-1 (metiltestosterone as positive control). The parameter measured was the percentage of male fish produced. The results showed that although the effect of the treatment was not significantly different, but it can be said to be significantly different to the treatment of 0 mg L-1 (control) to obtain the best result for masculinization of guppy at 30 mg L-1 immersion and the best survival rate on treatment of 0 mg L-1 (control). The re-sults of this study suggest that the masculinization technology on the parent stock can be done using extracts of sea cu-cumber innards which has been considered as waste.AbstrakIkan gapi Poecilia reticulata merupakan salah satu jenis ikan hias air tawar yang banyak digemari karena mudah dipe-lihara, dan memiliki variasi wama yang indah, terutama jantannya. Salah satu metode untuk menghasilkan ikan gapi jantan adalah dengan metode pembalikan kelamin melalui produksi penjantanan ikan gapi. Penelitian ini bertujuan un-tuk menentukan dosis hormon perlakuan ekstrak jeroan teripang pasir terhadap proses penjantanan ikan gapi. Penelitian  ini menggunakan rancangan acak lengkap dengan perlakuan perendaman induk ikan gapi yang telah dipijahkan ke dalam larutan ekstrak jeroan teripang pasir selama 24 jam dengan dosis berbeda, yaitu 0 mg L-1, 10 mg L-1, 20 mg L-1, 30 mg L-1 dan 22 mg L-1 (metiltestosteron sebagai kontrol positif). Parameter yang diukur adalah persentase ikan jantan yang dihasilkan. Hasil penelitian menunjukkan bahwa walaupun pengaruh antarperlakuan yang diberikan tidak berbeda nyata, tetapi dapat dikatakan berbeda nyata terhadap perlakuan 0 mg L-1 (kontrol) sehingga diperoleh hasil terbaik untuk penjantanan ikan gapi pada dosis perendaman 30 mg L-1  dan sintasan terbaik pada perlakuan 0 mg L-1 (kontrol). Hasil penelitian ini memberikan informasi bahwa teknologi penjantanan pada induk ikan gapi dapat dilakukan dengan me-manfaatkan ekstrak jeroan teripang pasir yang selama ini dianggap sebagai limbah.

One of the technologies to keep the water quality remains optimal ias a recirculation system. This research is aimed to determine the influence of denisity of catfish (Clarias gariepinus) on the recirculation system. Fish test used is catfish fry the age of 2 weeks with average weight 0.58 g and an average length of 2.7 cm as much as 10,000 fish. The experimental research used completely randomized design with 4 treatments and 3 replications. The treatments were A (20 fish/liter of water), B (30 fish/liter of water), C (40 fish/liter of water) and D (50 fish/liter of water). The survival rate, the feed efficiency, and water quality has been observed. The results of research showed that the survival rate and the feed efficiency were significantly different (P<0.05). The highest survival rate in this research was in the treatment A (20 fish/liter of water) that was 70.5%. The stocking density of catfish fry of 20 fish/liter of water can be used as basis for  the maintenance of catfish fry for reach the optimal survival rate. Key words: Catfish, survival rate, feed efficiency, recirculation
