Abstrak: Penelitian ini bertujuan untuk mengevaluasi pengaruh suplementasi tepung daun kayu manis pada pakan terhadap kinerja pertumbuhan ikan lele (Clarias gariepinus). Penelitian menggunakan empat perlakuan yaitu penambahan tepung daun kayu manis sebanyak 0%, 0,5%, 1,0%, dan 1,5% pada pakan komersial. Ikan lele dipelihara dalam waring 1x1x1 m3 yang diletakkan di dalam kolam beton dengan padat tebar 20 ekor/waring selama 30 hari. Ikan lele diberi pakan secara at satiation. Hasil penelitian menunjukkan bahwa penambahan tepung daun kayu manis pada pakan tidak memengaruhi rasio konversi pakan, namun penambahan daun kayu manis 1,5% pada pakan dapat meningkatkan pertumbuhan ikan lele dan menurunkan kadar lemak dagingnya (P<0,05). Kesimpulan penelitian ini penambahan tepung daun kayu manis pada pakan berpengaruh terhadap kinerja pertumbuhan ikan lele (C. gariepinus)., This study aims to evaluate the effect of cinnamon leaf powder supplementation on feed on the growth performance of Clarias gariepinus catfish. The study used four treatments, namely the addition of cinnamon leaf flour as much as 0%, 0.5%, 1.0%, and 1.5% in commercial feed. The catfish were kept in a 1x1x1 m3 net placed in a concrete pond with a stocking density of 20 fish/net cage for 30 days. Catfish were fed at satiation. The results showed that the addition of cinnamon leaf powder to the feed did not affect the feed conversion ratio, but the addition of 1.5% cinnamon leaf to the feed increased the growth of catfish and reduced the fat of meat (P<0.05). So it can be concluded that the addition of cinnamon leaf powder to feed had a significant effect on the growth of Clarias gariepinus catfish.

Judul: Response of Addition Insulin Leaf (Smallanthus  sonchifolius) in Feed to Growth Performance of Catfish (Clarias gariepinus)
Abstrak: Pemanfaatan karbohidrat sebagai protein sparing effect perlu dilakukan untuk meningkatkan kinerja pertumbuhan pada ikan lele (Clarias gariepinus).Upaya yang dapat dilakukan adalah dengan penambahan daun insulin dalam pakan. Penelitian menggunakan lima perlakuan dan tiga kali ulangan, sebagai perlakuan yaitu penambahan daun insulin 0%, 0,5%, 1,0%, 1,5%, dan 2,0%. Ikan dengan bobot 3,98±0,01 g dipelihara di tangki IBC (Intermediet Bulk Container) ukuran 100 x 100 x 100 cm3 sejumlah 15-unit dan setiap unit ditebar 100 ekor ikan. Pemeliharaan dilakukan selama 49 hari dengan pemberian pakan tiga kali sehari secara at satiation. Hasil penelitian menunjukkan perlakuan pakan dengan penambahan daun insulin 1% dapat meningkatkan biomassa akhir, tingkat kelangsungan hidup, protein efficiency ratio, dan specific growth rate serta menurunkan jumlah konsumsi pakan dan feed convertion ratio. Kesimpulan penelitian ini yaitu suplementasi daun insulin 1% pada pakan dapat meningkatkan kinerja pertumbuhan ikan lele., Utilization of carbohydrates as protein sparing effects needs to be done to improve growth performance in catfish (Clarias gariepinus). The effort that can be made is by adding insulin leaves in feed. The study used five treatment and three replications, as a treatment, namely the addition of 0% insulin leaves, 0.5%, 1.0%, 1.5%, and 2.0%. Fish with a weight of 3.98 ± 0.01 g is kept in the IBC (Intermediate Bulk Container) tank size of 100 x 100 x 100 cm3 in the amount of 15-unit and each unit was stocked by 100 fish. Maintenance was carried out for 49 days with feeding three times a day ad saving. The results showed feed treatment with the addition of 1% insulin leaves could increase the final biomass, survival rate, protein efficiency ratio, and specific growth rate and reduced the amount of feed consumption and feed convertion ratio. The conclusion of this study is that 1% insulin leaf supplementation in feed can improve the growth performance of catfish
