Abstract
Taro leaves are one of the potential alternative raw materials that can be used as a raw material for catfish feed. The purpose of this study was to evaluate the effect of A. niger fermentation on taro leaf flour on the digestibility and growth of catfish (Clarias sp.). The study was conducted with a Completely Randomized Design, consisting of 3 treatment levels and three replications: A (control/reference feed), B (70% reference feed + 30% unfermented taro leaf flour), and C (70% reference feed + 30% fermented taro leaf flour). Sangkuriang catfish seeds were placed in 9 aquariums, each with 10 fish per aquarium. Fish were fed 3 times a day using the ad station method for 40 days. The results showed that the highest total digestibility value (P<0.05) was found in the fermented taro leaf flour treatment with A. niger (73.38%) compared to other treatments. The highest material digestibility value (P<0.05) was also found in the fermented taro leaf flour treatment with A. niger (94.90%) compared to the unfermented taro leaf flour treatment. The highest nutrient digestibility (protein, fat, and energy) was significantly (P<0.05) found in the fermented taro leaf flour treatment with A. niger, with protein digestibility at 91.66%, fat digestibility at 87.30%, and energy digestibility at 78.66%. The survival rate of all treatments was 100%. Water quality during the study was within the normal range for catfish seed maintenance, and hematological parameter values were within the normal range.

| Additional Information: | Daun talas merupakan salah satu bahan baku alternatif yang berpotensi digunakan sebagai bahan baku pakan lele. Tujuan penelitian ini adalah untuk mengevaluasi pengaruh fermentasi A. niger pada tepung daun talas terhadap kecernaan dan pertumbuhan ikan lele (Clarias sp.). Penelitian ini dilakukan dengan menggunakan Rancangan Acak Lengkap (RAL), yang terdiri dari 3 tingkat perlakuan dengan tiga kali ulangan: A (pakan kontrol/referensi), B (70% pakan referensi + 30% tepung daun talas tanpa fermentasi), dan C (70% pakan referensi + 30% tepung daun talas terfermentasi). Benih ikan lele Sangkuriang ditempatkan dalam 9 akuarium, masing-masing berisi 10 ekor ikan per akuarium. Ikan diberi pakan sebanyak 3 kali sehari menggunakan metode ad station selama 40 hari. Hasil penelitian menunjukkan bahwa nilai kecernaan total tertinggi (P<0,05) ditemukan pada perlakuan tepung daun talas terfermentasi dengan A. niger (73,38%) dibandingkan dengan perlakuan lainnya. Nilai kecernaan bahan tertinggi (P<0,05) juga ditemukan pada perlakuan tepung daun talas terfermentasi dengan A. niger (94,90%) dibandingkan dengan perlakuan tepung daun talas tanpa fermentasi. Kecernaan nutrien tertinggi (protein, lemak, dan energi) secara signifikan (P<0,05) ditemukan pada perlakuan tepung daun talas terfermentasi dengan A. niger, dengan kecernaan protein sebesar 91,66%, kecernaan lemak sebesar 87,30%, dan kecernaan energi sebesar 78,66%. Tingkat kelangsungan hidup pada semua perlakuan mencapai 100%. Kualitas air selama penelitian berada dalam kisaran normal untuk pemeliharaan benih ikan lele, dan parameter hematologi berada dalam rentang normal. | |||||||||
