Determination of dipping time are very important to increase growth. The purposes of this research are determining the optimum dipping time for the growth and survival rate of snakehead larvae. This research was done at Laboratorium Dasar Perikanan, Aquaculture, Faculty of Agriculture, University of Sriwijaya, Indralaya. The method used Competely Randomized Design (RAL) with five treatments and three replicates, with dipping time are 24, 27, 30, 33 and 36 hours. The parameters observed are the absolute length growth, absolute weight growth, survival rate of larvae and water quality (temperature, pH and disolved oxygen). The results showed that the duration of immersion in thyroxine hormone solution in snakehead larvae showed relatively faster growth on treatment (P5) with 36 hours of dipping time. While the regression test result showed the optimal growth of snakehead larvae at the time immersion for 27,92 – 29,49 hours. Thyroxine hormone increased the growth of snakehead larvae but has no statistically significant effect. The length of time of thyroxine hormone 24-36 hours with a dosage of 0.1 mg l-1 did not affect the survival of snakehead larvae. Water quality of maintenance media is still tolerance for supporting the growth and survival of snakehead larvae.

Tanaman wori merupakan salah satu tanaman kelompok fabaceace yang tumbuh melimpah di Sangihe dan sangat potensial digunakan sebagai salah satu sumber pakan ikan. Kadar protein daun wori adalah 25,53% sehingga berpotensi menjadi protein nabati bagi ikan. Kendala utama yang ditemui ketika memanfaatkan daun tanaman wori adalah kandungan karbohidrat yang tinggi yaitu 48,51% sehingga dapat mempengaruhi proses pencernaan ikan, penyerapan nutrisi yang berujung pada rendahnya pertumbuhan ikan. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh tepung daun wori femerntasi terhadap laju pertumbuhan spesifik dan sintasan hidup ikan nila. Rancangan percobaan yang digunakan adalah Rancangan Acak Lengkap (RAL). Perlakuan yang dilakukan terdiri dari tiga perlakuan dan tiga kali ulangan yaitu kadar tepung daun wori tanpa fermentasi A (kontrol) 10%, kemudian B tepung daun wori fermentasi (10%), dan C tepung daun wori fermentasi (20%). Laju pertumbuhan spesifik dan efisiensi pakan diuji menggunakan ANOVA sedangkan sintasan hidup akan dianalisis secara deskriptif. Hasil penelitian ini menunjukan bahwa penambahan tepung wori fermenasi dalam pakan dapat meningkatkan nilai laju pertumbuhan spesfik ikan nila dan efisiensi pemanfaatan pakan dengan nilai tertinggi pada perlakuan C yaitu SGR 1,94%/hari. Sementara itu, untuk semua perlakuan nilai sintasan hidup sebesar 100%.   The wori plant is one of the plants of the fabaceace group that grows abundantly in Sangihe and has potential to be used as a source of fish feed. The protein content of wori leaves is 25.53%, so it has the potential to become vegetable protein for fish. The main obstacle encountered when utilizing wori plant leaves is the high carbohydrate content of 48.51% so that it can affect the digestion process of fish, nutrient absorption which lead to low fish growth. The purpose of this study was to determine the effect of wori femerntation leaf meal on the specific growth rate and survival of tilapia. The experimental design used was a completely randomized design (CRD). The treatments consisted of three treatments and three replications, namely the content of fermented wori leaf powder, A (control) 10%, then B fermented wori leaf powder (10%), and C fermented wori leaf powder (20%). Specific growth rate and feed efficiency were tested using ANOVA, while survival rate was analyzed descriptively. The results of this study indicate that the addition of fermented wori powder in the feed can increase the value of the specific growth rate of tilapia and feed utilization efficiency with the highest value in treatment C, namely SGR 1.94% / day. Meanwhile, for all treatments the survival rate was 100%.
