Analisis Kualitas Air Budidaya Ikan Lele Sangkuriang (Clarias gariepinus) di Kabupaten Manokwari, Papua Barat

Sangkuriang catfish (Clarias gariepinus) a freshwater fish, that is well-known as aquaculture commodity in Manokwari Regency. Water quality is a determining factor for the success of catfish farming. The purpose of this study is to determine the dynamics of water quality and to determine the feasibility of catfish culture water quality in Manokwari Regency according to the required quality standards. The method used was descriptive by direct field data collection in Prafi and Masni Districts, which are known as catfish farming centers. The results showed that in the Prafi ponds temperature was 28 - 31 0C, pH: 6.8 – 7.56 and DO: 3.2 - 6.2 ppm and the Masni temperature 27 -31 0C, pH 6.62 - 7, 60 and DO: 3.2 – 7.1 ppm. Nitrate concentrations in the Prafi ponds ranged from 0.8 to 1 mg/l and in the Masni ponds from 0.7 to 1.2 mg/l. Ammonia concentrations in the Prafi and Masni ponds ranged from 0.06  to ≥ 0.5 mg/L. Temperature, pH, DO and Nitrate are in accordance to  the required quality standards while Ammonia is not in accordance to the quality standards of Government Regulation Number 82/2001.Ikan lele sangkuriang (Clarias gariepinus) merupakan komoditas ikan budidaya ikan air tawar di Kabupaten Manokwari. Kualitas air merupakan faktor penentu keberhasilan kegiatan budidaya ikan lele. Tujuan dari penelitian ini yaitu untuk mengetahui dinamika kualitas air dan untuk mengetahui kelayakan kualitas air budidaya ikan lele di Kabupaten Manokwari berdasarkan baku mutu yang disyaratkan. Metode yang digunakan adalah pengumpulan data langsung di lapangan yaitu di Distrik Prafi dan Masni yang merupakan sentra budidaya ikan lele sangkuriang. Hasil penelitian menunjukkan bahwa suhu di kolam Prafi 28 - 31 0C, pH: 6.8 – 7.56 dan  DO: 3.2 - 6.2 ppm sedangkan kolam Masni memiliki  suhu: 27 - 31 0C, pH: 6.62 – 7.60 dan DO: 3,2 - 7,1 ppm. Konsentrasi Nitrat di kolam Prafi berkisar 0,8 - 1 mg/l dan kolam Masni 0.7 - 1.2 mg/l. Konsentrasi amoniak di kolam Prafi dan kolam Masni berkisar 0.06 ≥ 0.5 mg/L. Suhu, pH, DO dan Nitrat sesuai dengan baku mutu yang disyaratkan sedangkan Amonia tidak sesuai dengan baku mutu PP Nomor 82 Tahun 2001
