| Abstrak (Bhs. Indonesia) | Ikan nilem (Osteochilus vittatus) merupakan komoditas air tawar yang cukup populer. Budidaya ikan nilem secara intensif sering terkendala penurunan kualitas air. Sistem resirkulasi akuakultur diketahui dapat menanggulangi masalah tersebut. Zeolit dan kangkung air (Ipomoea aquatica) banyak digunakan dalam upaya perbaikan kualitas air. Penelitian ini bertujuan untuk mengetahui kualitas air dan pertumbuhan ikan nilem serta hubungan antara kedua variabel tersebut pada dua sistem resirkulasi yang berbeda (sistem resirkulasi filter zeolit dan sistem resirkulasi filter kangkung air) serta menganalisis perbedaan kualitas air dan pertumbuhan ikan nilem pada ke dua sistem resirkulasi tersebut. Metode yang digunakan adalah eksperimental RAL dengan tiga kali ulangan. Ikan nilem dipelihara pada sistem resirkulasi dengan padat tebar 100 individu selama 60 hari. Pengukuran kualitas air dan pertumbuhan ikan nilem dilakukan pada hari ke-0, 30, dan 60. Parameter yang diukur yaitu suhu air, TSS, DO, CO2, pH, NH3, dan berat ikan nilem. Analisis data menggunakan metode deskriptif. Hasil menunjukkan bahwa kualitas air dan pertumbuhan ikan nilem pada sistem resirkulasi dengan filter zeolite dan sistem resirkulasi dengan filter kangkung air cenderung sama secara umum. Kualitas air pada ke dua sistem resirkulasi masih cukup untuk pertumbuhan ikan nilem. |

| Abtrak (Bhs. Inggris) | Nilem (Osteochilus vittatus) is a popular freshwater commodity. Intensive production of nilem is often limited by water quality degradation. Recirculating aquaculture system is known to have advantage over this problem. Zeolites and water spinach (Ipomoea aquatica) are widely used in water remediation effort. This research aimed to find out water quality and nilems’ growth in two distinct recirculating system (zeolite filter based recirculating system; water spinach based recirculating system) as well as the relation between these variables. Furthermore, the difference in water quality and nilem’s growth between the two recirculating system was also evaluated. The method used was a completely randomized experimental design with three replication. Nilems were reared in recirculating system with a density of 100 individuals for 60 days. Measurement of water quality and nilem’s growth was conducted on day 0, 30, and 60. The measured parameters included water temperature, TSS, DO, CO2, pH, NH3 and nilem’s weight. Analysis of data in was completely done with descriptive method. The result showed that water quality and nilem’s growth in recirculating system using zeolite filter and in recirculating system using water spinach filter was similar in general. Water quality in both recirculating system was sufficient to promote nilem’s growth. |
