| Abstrak (Bhs. Indonesia) | Penelitian ini bertujuan untuk: 1) Mengetahui pengaruh populasi ikan lele terhadap pertumbuhan dan hasil tanaman Azolla microphylla, 2) Mencari populasi dan umur lele terbaik bagi pertumbuhan dan hasil tanaman Azolla microphylla. Penelitian dilaksanakan pada bulan Oktober 2018 sampai Januari 2019 di Desa Susukan, Kecamatan Sumbang, Kabupaten Banyumas. Penelitian menggunakan Rancangan Acak Kelompok Lengkap (RAKL) yang terdiri dari satu faktor dan tiga ulangan. Faktor yang diteliti adalah populasi ikan lele pada kolam Azolla, yang terdiri dari 6 taraf kerapatan yaitu 0 ekor/m2, 15 ekor/m2, 30 ekor/m2, 45 ekor/m2, 60 ekor/m2 dan 75 ekor/m2. Data dianalisis menggunakan uji F, dan apabila berbeda nyata dilanjutkan dengan uji BNT 5%. Variabel yang diamati yaitu kadar N, P, K dan nilai Electrical Conductivity (EC) air kolam, panjang akar, warna akar, persentase penutupan, doubling time, waktu recovery, kandungan klorofil, bobot segar panen 20%, 90%, 100% dan bobot kering. Hasil penelitian menunjukkan bahwa populasi ikan lele berpengaruh sangat nyata terhadap kadar N, P, K air kolam, berpengaruh nyata terhadap panjang akar dan warna akar Azolla microphylla, nilai Electrical Conductivity (EC) air kolam pada umur tanaman 42 hst dan 49 hst serta persentase penutupan Azolla microphylla umur tanaman 57 hst dan 60 hst. Populasi ikan lele dengan kerapatan 75 ekor/m2 merupakan populasi terbaik untuk meningkatkan kadar N, P, K air kolam dibanding perlakuan kontrol. Populasi ikan lele sebanyak 60 ekor/m2 kolam merupakan perlakuan terbaik untuk meningkatkan pertumbuhan akar A. microphylla, sedangkan populasi ikan lele sebanyak 45 ekor/m2 merupakan perlakuan terbaik untuk meningkatkan nilai variabel EC dan persentase penutupan. |

| Abtrak (Bhs. Inggris) | The objectives of this research were to: 1) Determine the effect of catfish population on the growth and yield of Azolla microphylla plant, 2) Find the best population and age of catfish for the growth and yield of Azolla microphylla plant. The study was conducted in October 2018 until January 2019 in Susukan Village, Sumbang District, Banyumas Regency. The study used a Complete Randomized Block Design (CRBD) consisting of one factor and three replicates. The factor evaluated was catfish population in Azolla pond with 6 density levels, i.e. 0 individual/m2, 15 individuals/m2, 30 individuals/m2, 45 individuals/m2, 60 individuals/m2 and 75 individuals/m2 Data were analyzed using ANOVA test and continued with LSD 5% test if significantly different results found. The variables observed were N, P, K levels and Electrical Conductivity (EC) value of the pond water, root length, root color, coverage percentage, doubling time, recovery time, chlorophyll content, yield of 20%, 90%, 100% and dry weight. The results showed that the population of catfish gave a very significant effect on the level of N, P, K of pond water. It also significantly affected root length and colour of Azolla microphylla, Electrical Conductivity (EC) value of pond water at 42 and 49 days after planting, and coverage presentation of Azolla microphylla at 57 and 60 days after planting. It was found that the pond containing catfish with the density of 75 individuals/m2 was the best treatment to increase the levels of N, P, K of the pond water. Moreover, the population of 60 catfish/m2 was the best treatment to increase A. microphylla root growth, whereas 45 catfish/m2 was the best treatment to increase the EC value and closing percentage. |
