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

ABSTRACTThe mass death of fish in a lake or a fish pond sometime occurs due to unmonitored its water quality. This problem leads to farmer’s profit losses that can not be avoided. Therefore, to overcome the problem it requires an applied system that able to monitor fish pond water quality. This paper proposes an application for monitoring lake or fish pond water quality based on acidity(PH), turbidity, dissolved oxygen (DO) and water temperature parameters. The main objectives is to provide early warning when the fish pond’s water quality is close to the threshold of danger. Thus the mass death of fish can be avoided and minimized. In addition, the water quality data measured by the sensor will be collected in the data logger and be forwarded to the data using the cellular network. All the submitted data will be stored and displayed on the website enable to be accessed from anywhere and can be used by interested parties.Keywords: Monitoring, Quality, Lake,Mitigation, Disaster, IOTABSTRAKKematian masal ikan yang hidup disuatu danau kadang terjadi akibat terlambatnya atau tidak termonitoringnya kualitas air di danau tersebut, sehingga kerugian yang dialami oleh peternak tidak dapat dihindari.

A study was conducted to evaluate the water quality parameters of pond water at Mymensingh Urban region. The water samples were collected from 30 ponds located at Mymensingh Urban Region during August to October 2010. The chemical analyses of water samples included pH, EC, Na, K, Ca, S, Mn and As were done by standard methods. The chemical properties in pond water were found pH 6.68 to 7.14, EC 227 to 700 ?Scm-1, Na 15.57 to 36.00 ppm, K 3.83 to 16.16 ppm, Ca 2.01 to 7.29 ppm, S 1.61 to 4.67 ppm, Mn 0.33 to 0.684 ppm and As 0.0011 to 0.0059 ppm. The pH values of water samples revealed that water samples were acidic to slightly alkaline in nature. The EC value revealed that water samples were medium salinity except one sample and also good for irrigation. According to drinking water standard Mn toxicity was detected in pond water. Considering Na, Ca and S ions pond water was safe for irrigation and aquaculture. In case of K ion, all the samples were suitable for irrigation but unsuitable for aquaculture.J. Environ.

Semi-intensive common carp (Cyprinus carpio) farm technology uses several feed types affecting the growth performance; however, we know less about their long-term effects on water quality. Herein, we evaluated the effects of three commonly used feeds—moderate levels of fish meal and fish oil feed (FF), plant meal and plant oil feed (PF), and cereal feed (CF) on the nutrient (total nitrogen (TN), total phosphorus (TP) and organic matter (OM)) content of the pond water. The experiment was carried out over three consecutive years from juveniles to market-sized fish. The type of feed affected the net yields, but generally, it did not affect the water quality. The year of sampling, however, was a significant factor affecting TN, TP, and OM, whose concentrations decreased during the three years. Our findings highlight that the age of the stocked fish on water quality has a more pronounced effect than the nutrient profile of the supplementary feed. Additionally, the plant-based feed could provide comparable net yields as the fish meal-based feed without additional nutrient loading in the water column, reinforcing the sustainability of alternative feeds in semi-intensive carp farming.

Abstract The floating photovoltaic panel is increasingly being used. This is one of the ways to reduce temperature rise in photovoltaic panel. The floating photovoltaic panel is used for lighting at the fish pond. A unit of 8-watt lamp for lighting supplied by 1 unit of 50 Wp photovoltaic panel and 1 unit of 12 V/3.5 Ah battery. The heatsink attached to the bottom of the floating photovoltaic panel transfers heat from the panel to the fish pond water. Sensors are connected to Arduino to measure photovoltaic panel output voltage and current, solar irradiance, photovoltaic panel temperature and fish pond water temperature. From the measurement, the voltage generated from the floating photovoltaic panel is 12.71 – 14.71 V and the current is 0.15 - 1.17 A. While the solar irradiance value is 71 W/m2 to 396 W/m2, the surface temperature of photovoltaic panel is 26.9°C - 32.4°C and fish pond water temperature is 27.1°C - 30.2°C.
