Siak River is one of the biggest rivers and the deepest in Riau Province in Indonesia with its 20-30 depth and depth 370 kilometers. The Siak River used for bathing, washing, dumping industrial palm oil, plantation, domestic waste, and port so it has an impact on water quality changing. This study analyzed the water quality and distribution spatial physical and chemical parameters the river around in Pekanbaru city, using Principal Component Analysis (PCA), this study used laboratory in situ and ex situ water quality measurement instruments. Water sampling each station done three times in two weeks during October to November 2019. The results obtained from this study shows the water quality of these 6 stations in the category of bad and the water quality from headwaters to downstream river influenced by organic parameter as a dominant pollutant. The correlation of water quality characteristic was 74.4% main factor 1 (F1) 47.4% and main factor 2 (F2) 26.7% with main characteristics fecal coliform, phosphate, and nitrate. Grouping these characteristics through a dendrogram showed three levels of relationship based on the characteristic parameter. The first group stands for station 1,2, and 4 have higher brightness and Dissolved oxygen (DO) parameters than other stations. The second group stands for stations 3 and 5 that have relatively high in parameter phosphate and nitrate. The third group is station 6 (river estuary) which results in shows high of fecal coliform proportional to pollution. The study can be concluded that three groups heavily contaminated. Each group has different parameters that show influence upland and waters activities.Keywords: Distribution of spatial, The quality of water, Siak River, Physical and Chemical Parameters, PCA ABSTRAKSungai Siak merupakan salah satu sungai terbesar di Provinsi Riau dan terdalam di Indonesia, dengan kedalaman sekitar 20-30 meter dan panjang 300 kilometer. Sungai siak masih dimanfaatkan oleh masyarakat sebagai sarana Mandi Cuci Kakus (MCK), tempat buangan limbah industri kelapa sawit, perkebunan, rumah tangga dan pelabuhan, sehingga berdampak pada perubahan kualitas perairan. Penelitian dilakukan untuk menganalisa kualitas dan distribusi spasial karateristik fisik-kimia perairan Sungai Siak di sekitar Kota Pekanbaru, dengan menggunakan Principal Component Analysis (PCA). Kajian menggunakan instrument pengukuran kualitas air in situ dan ex situ di laboratorium. Pengambilan sampel air pada masing-masing stasiun dilakukan sebanyak tiga kali setiap dua minggu selama bulan Oktober hingga November 2019. Hasil yang diperoleh dari kajian ini adalah kualitas air di keenam stasiun masuk dalam katagori buruk dan mengalami penurunan kualitas dari hulu ke hilir yang disebabkan bahan organik. Korelasi karakteristik kualitas air sebesar 74,3%, faktor utama 1 (F1)  47,4% dan faktor utama 2 (F2) 26,7% dengan penciri utama fecal coliform, fosfat dan nitrat. Pengelompokan stasiun pada dendogram klarifikasi hierarki menunjukkan adanya tiga tingkat hubungan kekerabatan berdasarkan parameter pencirinya. Kelompok satu terdiri dari stasiun 1, 2 dan 4 memiliki hasil relatif tinggi pada parameter kecerahan dan oksigen terlarut (DO) dibandingkan dengan stasiun lainnya. Kelompok dua terdiri dari stasiun 3 dan 5 memiliki hasil relatif tinggi pada paramter nitrat dan fosfat dibandingkan dengan stasiun lainnya. Kelompok tiga adalah stasiun 6 (muara sungai sail) dengan parameter fecal coliform relatif tinggi yang berbanding lurus dengan tingkat pencemarannya. Berdasarkan hasil kajian dapat disimpulkan bahwa tiga kelompok sama-sama tercemar berat, namun masing-masing kelompok memiliki perbedaan parameter pencirinya yang memperlihatkan pengaruh berbagai aktifitas di darat maupun di perairan itu sendiri.Kata kunci: Distribusi spasial, Kualitas air, Sungai Siak, Parameter fisika dan kimia, PCA

The ecological impact of human settlement on the water quality of Lower Cross River, Nigeria was evaluated. The physical and chemical conditions of the river water were determined from January to August, 2011. Three stations comprising Itu in Akwa Ibom State with intense human activities (station 2), its upstream (without human settlement) at Cross River State (station 1) and the downstream (station 3) were sampled. The Parametric One Way Analysis of Variance (ANOVA) indicated that of the 17 physical and chemical parameters determined, only water level and COD were found to be significantly different () among stations. The spatial variations in the level of significant correlation of the physical and chemical parameters among the stations and the higher level of interrelationship in downstream station 2 and 3 than station 1 could be attributed to inputs resulting from human settlement. Comparison between some parameters with Standard Organization of Nigeria, and World Health Organization maximum permitted levels for drinking water indicated that the water was not polluted. However, the BOD and COD concentrations of greater than 2 mg/L and 20 mg/L respectively were indicative of pollution.

Abstract Water is a social requirement and an important factor in the ecological balance. Water from wells is good for direct consumption if the soil is not contaminated. The quality of drinking water is regulated by Law no. 458/2002 (transposing the Directive 98/83/EC on the quality of drinking water). The aim of this paper was to assess the physicochemical qualities of groundwaters from Brestea village, commune Denta, Timis County. The water samples were taken in 2015 from 10 functional wells. For the source whose physical and chemical parameters have exceeded the limit values, the monthly monitoring of the water quality (microbiological and physico-chemical properties) has been performed for 2 years. At the same time, the pH of the soil near the water sources was also measured. The results highlighted a good connection between the microorganisms from water and the nitrite, nitrate and ammonium content of water. The information can be further used to identify and eliminate the specific pollutants, areas and pollution sources.

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

<p>The existence of Ephemeroptera, Plecoptera, and Trichoptera (EPT) in a body of water can be used as indicators of the quality of the waters. The aim of this study were 1) to know the diversity of EPT insects in Jangkok River, Lombok, West Nusa Tenggara, 2) determine the water quality of Jangkok River based on family biotic index (FBI), and 3) to know the effect of physical, chemical, and biological of environment parameters on the presence of EPT insects. Sampling was conducted in Jangkok River, Lombok, West Nusa Tenggara, in the dry season of July 2016. EPT groups insects were taken using water nets and eckman grab in 22 sampling points that was randomly determined in systematic random sampling. Data of physical, chemical, and biology of waters were also taken in these sampling points. Water quality is determined by the score of FBI, and the multiple correlation analysis to determine the relationship between physical and chemical parameters with the presence of EPT. Biological parameter was analyzed descriptively. The influence of biological parameter was determined by descriptive analysis. The study found 902 individuals of EPT belonging to 12 family and 12 genera. In the upstream we found 788 individuals (12 family and 12 genus), in the middlestream found 114 individuals (10 family and 10 genus), while in the downstream the EPT was absent. From the seven physical and chemical parameters of waters tested, only water temperature has significant correlation with the presence of EPT. The differences of water temperature in these area were caused by the covering and heterogeneity of the vegetation in the river side in each area. FBI score for upstream was 3.6 which indicates that the quality of the waters are very good. In the middlestream, the FBI score was 4.6, and it was categorized as good. In the downstream, results of the FBI get infinite value that entered the category as very bad.</p>
