Daun turi sangat potensial digunakan sebagai bahan pakan alternatif bagi ikan. kandungan nutrisi daun turi cukup baik, namun tingginya serat kasar menyebabkan pakan sulit dicerna, sehingga perlu dilakukan fermentasi. kandungan serat kasar yang tinggi pada daun turi menyebabkan pakan sulit dicerna. tujuan penelitian untuk mengetahui pengaruh dan dosis optimum penambahan tepung daun turi terfermentasi terhadap pertumbuhan benih ikan nilem. penelitian dilakukan dengan menggunakan metode rancangan acak lengkap (ral) dengan 6 perlakuan dan 3 ulangan. perlakuan a, b, c, d, e, dan f dengan konsentrasi masing-masing yaitu 0%, 8%, 10%, 12%, 14%, dan 16%. ikan uji yang digunakan adalah benih ikan nilem (osteochilus hasselti) yang dipelihara selama 40 hari dengan pemberian pakan pada pukul 07.00 wib, 12.00 wib, dan 17.00 wib. hasil terbaik terdapat pada perlakuan e (14%) dengan pertumbuhan panjang dan berat mutlak sebesar 1,12 cm dan 0,33 g, laju pertumbuhan spesifik sebesar 1,29%/hari, dan fcr sebesar 1,87%. penambahan tepung daun turi terfermentasi dalam pakan berpengaruh (p0,05) terhadap kelangsungan hidup benih ikan nilem. kata kunci : daun turi, pertumbuhan, pakan, fermentasi, ikan nilem

Turi leaf very potential to be used as an alternative feed ingredient for fish. The nutritional content of turi leaves is quite good, but the high crude fiber makes the feed difficult to digest, so fermentation is necessary. The aim of the research was to determine the effect and optimum dose of adding fermented turi leaf flour on the growth of nilem fish seeds. The research conducted using a completely randomized design (CRD) method with 6 treatments and 3 replications. Treatments A, B, C, D, E, and F with concentrations of 0%, 8%, 10%, 12%, 14%, and 16% respectively. The test fish used were nilem fish seeds (Osteochilus hasselti) which reared for 40 days with feeding at 07.00 WIB, 12.00 WIB and 17.00 WIB. The best results were found in treatment E (14%) with absolute growth in length and weight of 1.12 cm and 0.33 g, specific growth rate of 1.29%/day, and FCR of 1.87%. The addition of fermented turi leaf flour in feed on the growth of nilem larvae had a significant effect (P0.05) on seed survival. Keywords: Turi leaf, Growth, Feed, Fermentation, Nilem fish
