This service aims to provide information about the value of good water quality and demonstrate directly the tools used to measure it which aim to cultivate Batak fish based on biological, physical and chemical parameters such as temperature, dissolved oxygen, carbon dioxide, pH, and provide information on the names of measuring devices. . This service has been carried out in Gorat Village, Toba Samosir Regency with the method of counseling and material discussion (exposure and question and answer), as well as the practice of measuring water quality externally and analyzing the results of its value. The results of the counseling show that many fish farmers do not understand the value of good water quality for batak fish cultivation and not many know the equipment that can be used to check water quality. From this counseling, it can be seen that the interest of fish farmers and the community is very high, and they become more aware of the value of good water quality for fish farming and know the equipment. Abstrak Pengabdian ini bertujuan untuk memberikan penyuluhan tentang nilai kualitas air yang baik dan mendemonstrasikan langsung alat yang digunakan mengukurnya yang bertujuan untuk membudidayakan ikan batak berdasarkan parameter biologi, fisika dan kimia seperti suhu, oksigen terlarut, karbondioksida, pH, serta memberikan informasi nama alat-alat pengukurnya. Pengabdian ini telah dilakukan di Desa Gorat, Kabupaten Toba Samosir dengan metode penyuluhan dan diskusi materi (paparan dan tanya jawab), serta praktek pengukuran kualitas air secara eksitu dan menganalisis hasil nilainya. Hasil penyuluhan menunjukan bahwa banyaknya petani ikan yang belum paham tentang nilai kualitas air yang baik untuk budidaya ikan batak serta belum banyak yang mengetahui peralatan yang dapat digunakan untuk memeriksa kualitas air. Dari penyuluhan ini terlihat animo petani ikan dan masyarakat sangat tinggi, dan mereka menjadi lebih paham tentang nilai kualitas air yang baik untuk budidaya ikan serta mengetahui peralatannya.

Se evaluó la calidad de agua mediante parámetros físicos, químicos y microbiológicos en estanques utilizados para el cultivo de peces de ornato y de consumo, así como de la fuente de abastecimiento de una unidad de producción. Para ello, se evaluó un total de 14 parámetros físicos, químicos y microbiológicos durante dos temporadas de estiaje; frío (diciembre 2018 y febrero 2019) y cálido (marzo y mayo 2019) en siete estanques, así como la fuente de abastecimiento de agua. Los resultados obtenidos por algunos parámetros, mostraron concentraciones fuera de lo establecido para cultivo de peces. En cuanto al índice de calidad de agua (ICA) Dinius, se obtuvieron rangos de 60 a 80 los cuales permanecieron dentro de la clasificación de calidad que va de “excelente a aceptable” para pesca y vida acuática; con los rangos obtenidos se pueden agregar criterios para uso en riego agrícola y recreación.

Tegal Island is part of Lampung Bay which has potential to be the location of aquaculture. One of kind fish that can be cultivated in these area is the humpback grouper (Cromileptes altivelis). Humpback grouper is the most popular fish species in local and foreign markets that have the highest selling price. The purpose of this study were to know the physical and chemical parameters in Tegal Island waters, to know the suitability of the waters for the humpback grouper cultivation in the waters of Tegal Island. The research was conducted in May 2017. The sampling location was 4 stations. The range of water quality values in Tegal island were water depth (15-25 m), dissolved oxygen (7 – 8 mg/l), brightness (5-10 m), salinity (30-34 ppt), temperature (28 – 32°C ), current velocity (20 – 50 m/s), pH (7,7 – 8,0), nitrate (0,9 – 3,2 mg/l) and phosphate (0,2 – 0,5 mg/l). The results showed that the waters of Tegal Island had appropriate water suitability level (St 3), corresponding marginally (St 1 and St 2) and unsuited (St 4) for the cultivation of humpback grouper.

The purpose of this research was to analyze the physical and chemical parameters of waters (temperature, turbidity, pH, dissolved oxygen, nitrate, phosphate, ammonia and BOD) around net cage culture area at Peleloan Village, Minahasa Regency and to determine the suitable culture site supporting optimal growth of fish. water quality was measured at three sites. Temperature, turbidity, and pH were measured in situ while dissolved oxygen, nitrate, phosphate, ammonia and BOD were analised in laboratorium. Research results showed water temperature at all observation sites ranged from 25.5-28.2 0C, turbidity 2.02-3.15 m, pH 6.8 – 8.2, DO 7.41-7.77 mg/L, nitrate 0.3-0.5 mg/L, phosphate 0.00-0.4 mg/L, ammonia 0.13-0.77 mg/L. Based on water quality standard criteria stated in PP No. 82, 2001, temperature, turbidity, pH, DO and nitrate at fish culture area were suitable for floating and stick net cage cultures but ammonia at all sites of observation, phosphate at site I at 0.5 m from the bottom and BOD at site III at 0.5 m from the bottom were exceeding the standard criteria.

In this project, Polluted water sample from a Pond is collected for treating it by using Natural Coagulants. The pond is located in Madarpakkam Village, near Gummudipoondi, Tamilnadu, India. There were 4 water samples collected from four different points around the pond at depth of 0.5m, 1m, 1.5m and 2m. The water samples were analyzed for physical and chemical parameters with reference to the code IS 10500-1991. The objective of this project is to reduce the level of turbidity and bacteriological contaminants from water using locally available Natural Coagulants and to reduce the concentration of particular matter such as suspended particles, parasites, bacteria, algae, virus and fungi and to make use of the treated water for domestic purpose, as it reduces cost about 30% to 70%, the usage of these Natural coagulants will be more in future. It is nontoxic and non-corrosive. So, it is safe for human health. The usage of Natural coagulants can be increased in future as it increases the Water quality.

The aim of this study was to measure and assess the physical and chemical parameters of water quality in the area of ​​fixnet cage cultureat Lake Tutud Tombatu TigaVillagewhich included temperature, pH, DO, TDS, NO3, NO2, NH3 and PO4 in a different time.This research was conducted from August to November 2016. The research activities consisted of direct measurements in the field (in situ) using a Horiba instrument and laboratory analysis (ex situ) at the Agency for Industrial Research and Development Research Institute of Standardization and Industrial Manado. Determination points were done by purposive sampling which refers to the physiographic location wherever possible in order to represent or describe these waters.Water quality measured at4 stations using a Horiba at a depth of 0.5 meters from the bottom of the lake.Station I represented Inlet water, Station II where the cultivation A, Station III where the cultivation B and Station IVwhere no cultivation. The data obtained and collected were primary data i.e., measurement of physical and chemical parameters of water quality as well as watching for signs of sick fish, dead fish, and the growth of farmed fish.The results showed the water temperature ranged between 28-29 ° C, TDS 0266-0412 mg/L and chemical parameters for dissolved oxygen 2-5 mg/L, pH 7-8 and for the results of laboratory analysis, N03(0.7 - 6.3 mg/L), NO2(0001-0002 mg/L), NH3 (0180-1920 mg/L), PO4(0020-0209 mg/L). In general, the existence of water quality of lake Tutud were still in good condition except for NH3 concentrationthat exceeded quality standard limitsof Government Regulation No. 82 of 2001. Basically lake Tutud can still be used for fish farming, but the addition of new cages were not recommended.   Keywords: Lake Tutud,water quality, physical parameters, chemical parameters, fix net cage

The objective of this research was to measure and analyze the water quality parameters including temperature, brightness, pH, dissolved oxygen, total alkalinity, carbon dioxide and BOD in reservoir Embung Klamalu Sorong regency, and to know the factors that affected the water quality of Embung Klamalu. Measurement of water quality parameters was done in situ for temperature, brightness, pH and in laboratory for dissolved oxygen, total alkalinity, carbon dioxide, and BOD. The results showed the temperature at the five observation stations ranged from 26.2 to 29.8 0C, brightness 38 to 46 cm, pH 7.20 to 8.48 mg /L, dissolved oxygen from 7.20 to 8.48 mg / L, alkalinity 100 to 150 mg /L, carbon dioxide from 25.90 to 28.95 mg / L, BOD from 0.20 to 0.38. Refers to the standards of water quality according to the PP. 82, 2001, it could be concluded that water physical-chemical qualities in fish farming locations in the Village Klamalu were still in good condition.
