      Abstract
      Budidaya sistem bioflok merupakan teknologi akuakultur yang memanfaatkan bakteri heterotrop dalam mengelola limbah nitrogen. Penambahan molase sebagai sumber karbon berperan penting dalam meningkatkan aktivitas pertumbuhan biomasa bakteri (flok). Penelitian ini bertujuan untuk membandingkan metode pemberian molase yang berbeda dalam meningkatkan pertumbuhan dan kelangsungan hidup ikan nila sistem bioflok. Metode eksperimental yang digunakan yaitu perlakuan A (pemberian molase berdasarkan jumlah nitrogen pada pakan) dan perlakuan B (pemberian molase berdasarkan jumlah TAN dalam air). Analisis data dilakukan dengan cara data ditabulasi menggunakan Microsoft Excel 365, kemudian diolah secara deskriptif dengan melakukan studi pustaka. Kinerja pertumbuhan perlakuan B menghasilkan SR sebesar 93,41%, LPH 0,85 g hari-1, dan FCR 0,78. Penambahan molase berdasarkan jumlah TAN dalam air menunjukkan hasil terbaik, dibuktikan dengan nilai kinerja pertumbuhan dan SR tertinggi.
       
      The cultivation of biofloc systems is an aquaculture technology that utilizes heterotrophic bacteria to manage nitrogen waste. The addition of molasses as a carbon source plays a crucial role in enhancing bacterial biomass growth (floc) activity. This study aims to compare different methods of molasses administration in improving the growth and survival of tilapia in biofloc systems. The experimental methods used were Treatment A (molasses based on the amount of nitrogen in the feed) and Treatment B (molasses based on the amount of TAN in the water). Data analysis was conducted by tabulating data using Microsoft Excel 365 and then processed descriptively through literature review. The performance of treatment B resulted in an SR of 93,41%, LPH of 0,85 g day-1 , and FCR of 0,78. The addition of molasses based on the amount of TAN in the water showed the best results, as evidenced by the highest growth performance and SR.
