ABSTRAK Ikan lele membutuhkan pakan dengan kandungan protein sebesar 35-40% untuk menunjang pertumbuhan. Dari total pakan yang diberikan, 25 % pakan dapat dikonversi menjadi biomassa ikan, sisanya menjadi limbah (ammonia dan feses). Limbah hasil budidaya dapat diubah menjadi bioflok oleh bakteri heterotrof. Bioflok mengandung protein dalam biomassa bakteri dan polyhydroxybutyrate yang bermanfaat sebagai sumber energi dan dapat meningkatkan pertumbuhan ikan. Aplikasi bioflok selama ini digunakan untuk perbaikan kualitas air. Bioflok yang dimanfaatkan menjadi tepung sebagai suplemen pakan belum banyak diaplikasikan. Penelitian ini bertujuan untuk mengetahui penambahan tepung bioflok sebagai suplemen terhadap pertumbuhan lele sangkuriang. Rancangan penelitian yang digunakan adalah rancangan acak lengkap dengan empat perlakuan dan tiga kali ulangan. Perlakuan berupa pemberian pakan dengan penambahan tepung bioflok yang berbeda (0%, 5%, 10%, dan 15%). Pakan diujikan pada benih ikan lele sangkuriang ukuran 5-6 cm dengan bobot 2-2,5 gram yang dipelihara di kolam terpal berukuran 0,5x0,5x0,5 m selama 35 hari. Hasil penelitian menunjukkan bahwa penambahan tepung bioflok berpengaruh terhadap pertumbuhan. Semakin banyak penambahan tepung bioflok maka pertumbuhan ikan lele semakin meningkat. Kata kunci: lele sangkuriang, tepung bioflok , suplemen, pertumbuhan, poly-hidroxybutyrate ABSTRACT Catfish needs feed that contain 30-40% protein to support growth. From total feed which is given, 25% of the feed that can be converted into fish biomass, the rest becomes waste (ammonia and feces). The aquaculture’s waste can be converted as biofloc by heterotrophic bacteria. Biofloc contains proteins of bacteria and polyhydroxybutyrate which are used as the energy source and can enhance the growth of fish. All the time, application of biofloc is being used for water quality improvement. The biofloc which is used as biofloc meal for feed supplement had been rarely applied. This research aimed to know the addition supplemental biofloc meal to the growth of sangkuriang catfish. The research design used completely randomized design with four treatments and three replicates. The treatments are gives feed with the differently of addition biofloc meal (0%, 5%, 10%, dan 15%). Feed tested on juvenile sangkuriang catfish with size of 5-6 cm and weighs of 2-2.5 gram and were reared in container of 0,5x0,5x0,5 m for 35 days. The results showed that the use of biofloc meal significantly affected the growth of sangkuriang catfish. The more addition of biofloc meal, the higher catfish growth. Keywords: sangkuriang catfish, biofloc meal, supplement, growth, polyhidroxy-butyrate
