<![CDATA[Ikan lele Afrika (Clarias gariepinus) merupakan spesies asli Afrika yang telah diintroduksikan dan dibudidayakan secara komersial di Indonesia. Upaya peningkatan efisiensi produksi ikan lele terus ditingkatkan guna meningkatkan keuntungan. Salah satu upaya untuk meningkatkan efektivitas budidaya ikan lele adalah melalui penggunaan probiotik. Penelitian ini bertujuan untuk mengevaluasi pemanfaatan probiotik pada pembesaran ikan lele. Perlakuan yang diberikan berupa pemberian pakan hasil fermentasi probiotik dan pakan tanpa fermentasi (kontrol) dengan tiga ulangan. Pengujian dilakukan pada kolam terpal berukuran 3 m3 dengan padat tebar yang digunakan yaitu 500 ekor/wadah dan dipelihara selama 35 hari. Berdasarkan hasil pengujian, pemberian probiotik pada pakan dengan cara fermentasi mampu meningkatkan bobot dan biomassa panen secara signifikan (P<0,1). Bobot akhir ikan lele yang diberi pakan hasil fermentasi probiotik mencapai 76,9 ± 0,2 g; sedangkan kontrol 74,2 ± 0,2 g. Biomassa akhir ikan lele yang diberi pakan hasil fermentasi probiotik mencapai 37,91 ± 0,29 kg; sedangkan kontrol 34,65 ± 1,70 kg. Pemberian pakan yang difermentasi probiotik mampu meningkatkan retensi protein sebesar 1,02%; retensi karbohidrat sebesar 10,26%; dan retensi lemak sebesar 7,22%. Selain itu, penggunaan probiotik mampu menekan biaya produksi sebesar Rp 561,00/kg dan meningkatkan keuntungan sebesar 5%.African catfish (Clarias gariepinus) is a native African species that has been introduced and cultivated commercially in Indonesia. Efforts to increase the efficiency of catfish production were conducted in order to increase profit. One effort to increase the effectiveness of catfish farming is through the use of probiotics. This study was aimed to evaluate the use of probiotics in catfish farming. The treatments were fermented feed by probiotic and non fermented feed (control) and repeated three times. The experiment was conducted on a 3 m3 tarpaulin pond, with a density 500 fishes/pond, and reared for 35 days. Based on the results, the fermented feed by probiotic could increase the weight and biomass of harvested fish significantly. The weight of catfish fed with fermented feed reached 76.9 ± 0.2 g while the control was 74.2 ± 0.2 g. The final biomass of catfish fed with fermented feed reached 37.91 ± 0.29 kg while the control was 34.65 ± 1.70 kg. Feeding fermented feed by probiotic Gut Bio Aero increased the protein retention by 1.02%, carbohydrate retention by 10.26%, and lipid retention by 7.22%. The application of probiotic could reduce production cost by 561 IDR/kg and increased profit by 5%.]]>
