Uji kualitas air pada pedederan ikan kakap putih (lates calcalifer) di balai perikanan budidaya air payau ujung batee aceh besar abstrak ikan kakap putih (lates calcarifer) merupakan ikan laut yang memiliki nilai gizi tinggi dan nilai ekonomis yang cukup tinggi, dan merupakan sumber makanan yang banyak dicari. untuk menjamin pertumbuhan bibit ikan yang sehat dan ideal, dilakukan uji kualitas air di bak pembibitan ikan kakap putih (lates calcarifer) di balai pengembangan perikanan air payau ujung batee (bpbap ujung batee). alat dan bahan untuk melakukan uji kualitas air adalah colorimeter, ph meter, baju laboratorium, masker kimia, sarung tangan kimia, gelas blangko, salinitas meter. dan bahan yang di perlukan untuk uji kualitas air adalah, sampel air, amonia reagen, fospat reagen nitrat reagen nitrit reagen. pengambilan sampel diambil dari sebagian bak pedederan ikan kakap yang belum diganti air dan sampel air diambil masing-masing bak di ambil air sebanyak satu liter air per bak, dan menghitung salitas air. hasil uji kualitas air diperoleh nilai rata-rata ph (7,5), amonia (0,40 mg/l), nitrat (4,46 mg/l), nitrit (0.0045/ mg/l), fospat (0,60 mg/l), salinitas air (20,00 ppt). pertumbuhan benih ikan kakap putih dari minggu pertama berukuran 0,8cm dan 8 minggu mencapai 4,5-6cm perekor benih ikan kakap putih yang ada bpbap ujung batee aceh besar. rata-rata pertumbuhan benih ikan dari minggu 1-8 munggu adalah 0,5-1cm, berdasarkan hasil diatas kualitas air di bpbap ujung batee aceh besar sudah sangat baik untuk budidaya benih ikan kakap putih, serta pertumbuhan benih ikan kakap putih yang baik. kata kunci : ikan kakap putih, kualitas air

UJI KUALITAS AIR PADA PEDEDERAN IKAN KAKAP PUTIH (Lates calcalifer) DI BALAI PERIKANAN BUDIDAYA AIR PAYAU UJUNG BATEE ACEH BESAR ABSTRAK One marine fish with significant economic importance and great nutritional value is the white snapper (Lates calcarifer), which is used as a food. White snapper (Lates calcarifer) nursery beds at the Ujung Batee Brackish Water Aquaculture Fisheries Center (BPBAP Ujung Batee) are subjected to water quality testing in order to ensure the healthy and excellent growth of white snapper fry. Tools and materials to conduct water quality tests are colorimeters, ph meters, laboratory clothes, chemical masks, chemical gloves, blank glasses, salinity meters. And the materials needed for water quality testing are, water samples, ammonia reagents, phosphate reagents, nitrate reagents, nitrite reagents, reagents. Sampling was taken from a part of the snapper pederer tub that had not been replaced with water and water samples were taken respectively The tub takes water as much as one liter of water per tub, and calculates the salinity of the water. The results of the water quality test obtained average values of ph (7.5), ammonia (0.40 mg/L), nitrate (4.46 mg/L), nitrite (0.0045/ mg/l), phosphate (0.60 mg/L), water salinity (20.00 PPT). The growth of white snapper fry from the first week is 0.8cm and 8 weeks reaches 4.5-6cm of white snapper fry in BPBAP Ujung Batee Aceh Besar. The average growth of fish fry from 1-8 weeks is 0.5-1cm, Based on the above results, the water quality at BPBAP Ujung Batee Aceh Besar is very good for the cultivation of white snapper seeds, as well as good growth of white snapper seeds.
