Azolla microphylla merupakan salah satu bahan pakan yang dapat dimanfaatkan sebagai pakan tambahan ikan. Penelitian bertujuan untuk mengetahui pengaruh kombinasi pellet dan Azolla microphylla terhadap pertumbuhan berat mutlak, pertumbuhan berat relatif, SGR (Spesific Growth Rate), dan SR (Survival Rate) ikan Nila (Oreochromis niloticus) dalam sistem polikultur. Penelitian bersifat eksperimen menggunakan metode Rancangan Acak Lengkap (RAL) dengan 4 perlakuan, yaitu P1 (100% pellet), P2 (70% pellet dan 30% Azolla microphylla), P3 (50% pellet dan 50% Azolla microphylla), serta P4 (30% pellet dan 70% Azolla microphylla). Penelitian dilakukan selama 30 hari. Hasil penelitian menunjukkan bahwa pertumbuhan berat mutlak, pertumbuhan berat relatif, dan SGR memberikan hasil yang berbeda, sedangkan SR memberikan hasil yang sama. Nilai kisaran hasil pertumbuhan berat mutlak sebesar 1,98-2,63g; pertumbuhan berat relatif sebesar 51,09-69,92%; SGR sebesar 1,37-1,76%; dan SR sebesar 95-100%. Pengukuran kualitas air diperoleh hasil suhu berkisar antara 25-280C; pH berkisar antara 6-7; dan oksigen terlarut 5-11mg/L.

Azolla microphylla is one of feed ingredients that can be used additional fish feed. The research was aimed to determine the effect of feeds combination pellet and Azolla microphylla on absolute weight growth, relative weight growth, SGR (Spesific Growth Rate), and SR (Survival Rate) of Oreochromis niloticus in polyculture system. The research was experimental that used Completely Randomized Design with 4 treatments, namely P1 (100% pellet), P2 (70% pellet and 30% Azolla microphylla), P3 (50% pellet and 50% Azolla microphylla), and P4 (30% pellet and 70% Azolla microphylla). The research was conducted for 30 days. The results showed that absolute weight growth, relative weight growth, and SGR gave different results, while SR gave the same result. The range value of absolute weight growth results is 1,98-2,63g; relative weight growth of 51,09-69,92%; SGR of 1,37-1,76%; and SR of 95-100%. The measurement of water quality are obtained from the temperature range between 25-280C; pH ranges from 6-7; and dissolved oxygen 5-11mg/L.
