Abstract : Fertilization has an important role in overcoming nutrient deficiencies for plankton growth as natural fish food and plant growth in aquaponic systems. This study aims to determine the optimal dose of Azolla sp. liquid organic fertilizer in the limed swamp water for the culture of pangasius catfish and lettuce plants using an aquaponic floating raft system. This study used a completely randomized design with four treatments and three replications. The treatments were the different doses of Azolla sp. liquid organic fertilizer, namely 5 mL L-1 (P1), 10 mL L-1 (P2), 15 mL L-1 (P3), and 20 mL L1 (P4). Pangasius catfish (initial size 5 ± 0.5 cm) with a stocking density of 100 fish m-3 and lettuce plants that were sown for 23 days (3-4 lettuce leaves) and reared for 42 days. The results showed that of Azolla sp. liquid organic fertilizer at a dose of 5 mL L-1 (P1) was the best dose with ammonia 0.027-0.104 mg L-1 , nitrate 2.823-7.968 mg L-1 , phosphorus 0.01-0.84 mg L -1 , potassium 1.28-5.94 mg L-1 , total dissolved solid 42.67-183.67 mg L-1 , dissolved oxygen 3.23-4.47 mg L-1 , pH 7.17-7.95, temperature 27.53-28.27oC, absolute growth of weight 14.40 g, absolute growth of length 7.44 cm, survival rate 89%, catfish production 1,394.58 g m-3 and total weight of lettuce plants 88 g.

Keywords : Azolla sp.; Liquid Organic Fertilizer; Pangasius.
