Abstract The composition of water used for irrigation has a significant impact on the production characteristics of the land, yield and irrigation equipment, and therefore its analysis, or assessment of the usability of irrigation water is very important. In this paper, the potential impact of the waters of the Banat watercourses of Moravica, Karaš and Nera is assessed on the basis of monthly water samples from the measuring stations of Vatin, Dobričevo and Kusić, for the period of April-September from the year 2007 to 2017. The assessment was carried out using the classification of irrigation water: FAO, USLL and water categorization according to Nejgebauer, and the Serbian Water Quality Index (SWQI). For the needs of these classifications, a total of 20 water parameters were analyzed: quality, physical, chemical and biological parameters. According to all the classifications, the analyzed watercourses can be a good source of water for irrigation in terms of its quality, but with control and appropriate measures, in particular, the presence of bicarbonate, but also the ratio of Na+ to Ca2+ and Mg2+.

Physical and Chemical Parameters of Water Fish Pond Black Nile Tilapia (Oreochromis niloticus) Water is a natural resource that is essential for the survival of humans and other creatures, role of water is essential for life on earth, especially fish in the water habitat. Fish need a comfortable environment in order to be healthy and growing optimally. Therefore, the water, used as a habitat of life for the fish, have certain requirements. So the quality of the water must be very noted. Tilapia is a freshwater fish that has a great tolerance towards the environment, therefore it is highly appreciated by fish farmers in Indonesia.  Study of physical and chemical parameters in water of  tilapia fish pond was done due to lack of review of water quality of tilapia fish pond. The review is based on a sampling of water, i.e. morning and afternoon. A review of the pond water quality was expected to assist fish farmers got information about the qualities of water of tilapia fish pond in physical and chemical characteristics.  The method of this research was Grab (momentarily) methods in water sampling. Testing of water samples in physics done visually for color parameters, temperature using a thermometer device, and brightness parameters was using the secchi disk. In testing the chemical parameters were measurement of pH was using a pH meter Winkler method was done  for the parameters of dissolved oxygen (DO). Titrimetric method was done  for the parameters of  total hardness, and  carbon dioxide, whereas for ammonia parameter was done  by spectrophotometric method were measured using UV-Vissible. After testing all the parameters then interpretation was done for the parameter data.  The results showed the water quality of tilapia fish pond in the area Laladon – Bogor was not  yet qualified for a good fish pond water based on ISO 7550: 2009 Product ion of tilapia growing  level in calm water pond,  for parameter Ammonia levels should be <0.02 mg / L, and based on PPNo.8, on water Quality Standard by 2001. The difference in the parameter levels in the morning and during the day due to the process of respiration at night by the aquatic organisms that produce CO2 gas and the process of photosynthesis during the day by plankton, microalgae, and other aquatic plants to produce a compound O2. The existence of other human activities during the day also affects the difference in the data levels in the morning and day time.Keywords: Tilapia, pond water qualityABSTRAK Air merupakan sumber daya alam yang sangat penting bagi kelangsungan hidup manusia dan makhluk lainnya, Peranan air sangat penting bagi makhluk hidup di bumi terutama ikan yang berhabitat di dalam air. Ikan membutuhkan lingkungan yang nyaman agar dapat hidup sehat dan tumbuh secara optimal. Oleh karena itu  air yang digunakan sebagai sumber kehidupan bagi ikan, memiliki persyaratan tertentu. Sehingga kualitas dari air harus sangat di perhatikan. Ikan nila merupakan ikan air tawar yang memiliki nilai toleransi yang besar terhadap lingkungannya sehingga sangat diminati oleh petani ikan di Indonesia. Studi parameter fisika dan kimia pada air kolam ikan nila dilakukan karena kurangnya peninjauan terhadap kualitas air kolam ikan nila. Peninjauan tersebut dilakukan berdasarkan waktu pengambilan sampel air, yaitu pada pagi dan siang hari. Peninjauan kualitas air kolam diharapkan dapat membantu para petani ikan mendapatkan informasi mengenai kelayakan kolam ikan nila secara fisika dan kimia.  Metode yang dilakukan penelitian ini adalah metode Grab (sesaat) untuk pengambilan sampel air. Pengujian sampel air secara fisika dilakukan secara visual untuk parameter warna, suhu dengan menggunakan alat pengukur suhu, dan metode secchi disk untuk parameter kecerahan. Pada pengujian parameter kimia dilakukan pengukuran pH dengan alat pengukur pH. Metode Winkler dilakukan untuk parameter dissolved oxygen (DO). Metode titrimetrik dilakukan untuk parameter s kesadahan total, dan karbondioksida, sedangkan untuk parameter ammonia dilakukan dengan metode spektrofotometri yang diukur dengan menggunakan alat spektrofotometer UV-Vissible. Setelah dilakukan pengujian semua parameter maka dilakukan interpretasi data hasil penelitian.  Hasil penelitian menunjukan kualitas air kolam ikan nila di daerah Laladon – Bogor belum memenuhi syarat untuk air kolam ikan yang baik berdasarkan SNI 7550:2009 Produksi ikan nila tingkat  pembesaran di kolam air tenang, untuk parameter Ammonia dengan kadar <0,02 mg/L, dan  berdasarkan Baku Mutu PPNo.82 tahun 2001. Terjadinya perbedaan kadar pada pagi dan siang hari dikarenakan terjadinya proses respirasi pada malam hari oleh organisme air sehingga menghasilkan senyawa CO2 dan terjadinya proses fotosintesis pada siang hari oleh plankton, mikroalga, dan tanaman air lainnya sehingga menghasilkan senyawa O2. Adanya aktifitas lain pada siang hari juga mempengaruhi terjadinya perbedaan kadar pada pagi dan siang hari.Kata kunci : Ikan nila, Kualitas air kolam
