Abstract Riau Province has the Koto Panjang reservoir which is generated from the damming of the Kampar River flow for hydroelectric power generation and other utilization activities. The increase in community activities in reservoir waters and on land causes water quality dynamics that can affect fish farming activities. The purpose of this study was to determine the dynamics of reservoir water quality. The survey was conducted in March – August 2021 at seven sampling points, where water samples at each sampling point were taken at a depth of 1 m as much as 1 liter using a van dorn water sampler and preserved and analyzed according to standard methods. Data from measurement and analysis were tabulated and analyzed descriptively including temperature, pH, turbidity, TSS, TDS, DO, nitrate, ammonia, total nitrogen, BOD5, COD, and total phosphate. The results obtained indicate that the values of temperature, turbidity, TDS, TSS, pH, DO, ammonia, nitrate, and phosphate are still below the quality standard, except in the range of BOD values of 4.30 – 5.75 mg/L and COD of 17.90. – 23.73 mg/L is an indication of organic matter originating from other activities on the reservoir land, such as plantations, agriculture, settlements, tourism, apart from floating net cage cultivation activities.

Pollutant Sources

Pollution prevention must be carried out in the upstream, middle and downstream parts. One of the Citarum watersheds located in the middle part is the Cirata reservoir. Pollution in the Cirata reservoir does not only originate from the reservoir environment, but also from rivers that flow into the Cirata reservoir. Cirata Reservoir besides being a Hydroelectric Power Plant (PLTA) unit, this reservoir is also used by the community for fish farming in the Floating Net Pool (KJA) technique. This study aims to determine the most dominant pollutants contaminating the Cirata reservoir. Test of river and reservoir water quality is carried out with the help of lab tests by Labkesda. The research data was obtained by obtaining clean water quality test data from several 3 estuary points of the river flow to the Cirata reservoir and 4 centers of Cirata reservoir number of 40 samples. Data processing techniques are carried out using data mining, namely Exploratory Data Analysis. The lab parameter test results, which are compared with the Permenkes No. 32 Year 2017 standard, show that the majority of the physical and chemical quality parameters of the Citarum River which empties into the Cirata Reservoir are still within the required threshold. Most river and reservoir water samples have water quality that qualifies as clean water. Five samples (12.5%) in turbidity parameters and 1 sample (2.5%) in color samples did not qualify as clean water. This is possible because the sampling is too close to the mainland. Temperature parameters of 20 samples (50%) do not qualify as clean water is possible because of the lag time of sampling. The results of the analysis showed that the distance of pollutant sources, the amount of pollutant sources, and environmental conditions around the sampling significantly with temperature, TDS, turbidity, color, pH, nitrogen, iron, hardness, manganese, fluoride, and cyanide.

The Impact

Cirata Reservoir is one of the three cascade reservoirs fed by the Citarum Watershed with an area of ​​62 km2 (6.200 ha) and has a water volume of 1.900 million m3. The great potential of the waters in the Cirata Reservoir is utilized by the local community as a source of livelihood, namely by conducting aquaculture activities using floating net cages (FNC) in excess. FNC is thought to be a source of waste that reduces reservoir water quality. This research aims to determine the impact of FNC cultivation on primary productivity with different FNC densities at each station. The research was conducted in Cianjur Regency by taking on three stations, namely in the areas of Jangari, Maleber, and Patok Beusi on November 6 - December 8, 2019. The method used in the research was purposive sampling then analyzed in detail and quantitatively. The results show that reservoir waters have an average of physical parameters, namely temperature 32.2-32.6oC, transparency 0.59-0.68 meters, pH 7.1-7.3, carbon dioxide 15.4-16.1 mg / l, Dissolved Oxygen 6.9-7.3 mg / l, Biochemical Oxygen Demand 6.1-7.8 mg / l, nitrate 0.208-0.222 mg / l, ammonia 0.002833-0.003056 mg / l, phosphate 0,165-0,167 mg / l and primary productivity 240,36-277,90 mgC/m3/hour. This shows that the water indicator is still classified as good because it does not exceed the water quality standard.

The People

The development of an area must be accompanied by an ever-increasing population growth which will also increase the waste produced. Waste production will put pressure on the environment if it is not managed properly which will eventually end up in water bodies. The increased pollution load is also caused by the habit of people disposing of domestic waste, both liquid waste and solid waste directly into the water. Batujai Reservoir is one of the vital objects for the survival of the people of Central Lombok in particular, and the people of Lombok Island in general. Because of its vital role, the Batujai Reservoir needs to be saved so that the reservoir ecosystem can carry out its functions and benefits in improving the welfare of the people of Central Lombok. There are several community activities that are a source of direct reservoir water pollution (point source) such as fishing activities using floating net cages and disposal of domestic waste by the community which is directly channeled to water bodies. Pollutants collected in the Batujai Reservoir will reduce the water quality of the Batujai Reservoir. This research aims to analyze the water quality of the Batujai Reservoir which is caused by business activities and the community based on Government Regulation Number 82 of 2001 and to determine the water pollution index of the Batujai Reservoir. This study uses a quantitative approach by collecting primary data from direct observations in the field and secondary data based on previous research reports and government reports. The results showed that the average physical parameters were above the water quality standard threshold for class II water quality, the average chemical parameters were above the water quality standard for class III and class IV water quality, while the biological parameters were above the threshold. Water quality limits for class II and class III. The decline in water quality in the Batujai Reservoir is caused by various wastes entering the Batujai Reservoir water bodies. The analysis result with storet system shows that the water quality of Batujai Reservoir is in bad condition or heavily polluted.

The river water flow into the Lake Sipin, so worried farmers catfish (Pangasius hypopthalmus) in the floating  nets cage on heavy metal pollution Hg when exceeding quality standards. The content of Hg was observed through the method of survey study purposive sampling with 4 stations for 3 weeks of observation with sample analysis Atomic Absorption Spectrophotometer. The observation that the accumulation of heavy metals mercury (Hg) meat catfish in the lake Sipin from 0.0930 to 0.3960 ppm. Hg content is in torelansi SNI standards for heavy metals Hg categories food fishery products including mollusks and shrimp is 1 ppm and 0.5 ppm for predatory fish. So fish farming Lake Sipin still safe for consumption humans..Hg value of water is observed from 0.0001 to 0.0009 ppm. Hg content was lower when compared to the water quality standard by the Ministry of Environment No. 51 In 2004 the threshold value for the biota is 0.001 mg / l (ppm). Then the category of heavy metal content of Hg in the waters of Lake Sipin still at the threshold of normal. Occurrence repaired Hg waters presumably because the number found fish brooms, Hypostomus plecostomus and plant water hyacinth, Eichhornia crassipes which absorbed Hg in the waters. The state of water quality when the observation temperatures averaging 30-32 ° C, pH 6.6 to 7.4 and DO 7.0 to 8.4 ppm. The range of this parameter is feasible for the cultivation of catfish (Pangasius Hyphopthalmus), as it supports the growth and survival.Keywords: Bioaccumulation Hg, Lake Sipin, catfish AbstrakBadan Lingkungan Hidup Provinsi Jambi pada tahun 2014 menetapkan bahwa Sungai Batanghari  dikategorikan tercemari berat dengan limbah 0,3265 ppm.

Buangan limbah organik dari kegiatan budidaya ikan berdampak pada naiknya konsentrasi senyawa nitrogen di perairan. Tujuan penelitian ini adalah untuk mengetahui sebaran vertikal konsentrasi total nitrogen (TN), total fosfat (TP), dan amonia pada perairan pesisir yang berdekatan dengan kawasan budidaya ikan laut di Bali Utara. Titik sampling dipilih pada kedalaman 5, 10, 15, 20, dan 30 meter dengan arah tegak lurus garis pantai di kawasan perbenihan ikan dengan tingkat aktivitas tinggi (Desa Gerokgak dan Desa Penyabangan) dan tiga titik sampling di sekitar karamba jaring apung (KJA) di Teluk Kaping, Desa Sumberkima. Sampel air diambil pada bagian permukaan, tengah, dan dasar pada tiap titik sampling. Penelitian ini dilakukan pada tahun 2019 dengan dua periode waktu yaitu bulan April sampai Juni dan Agustus sampai Oktober dengan satu kali pengambilan contoh air setiap bulan. Hasil penelitian menunjukkan bahwa sebaran konsentrasi TN, TP, dan amonia secara vertikal cenderung homogen pada tiap titik pengamatan. Konsentrasi TN, TP, dan amonia selama penelitian berturut-turut adalah 1,2-1,5 mg/L; 0,081-0,090 mg/L; dan 0,054-0,057 mg/L. Nilai tersebut berada di bawah baku mutu air untuk kebutuhan budidaya ikan. Sebaran konsentrasi senyawa nitrogen dan fosfat secara vertikal di lokasi penelitian relatif homogen pada semua lapisan kedalaman air yang diamati. Kondisi tersebut menunjukkan bahwa proses percampuran masa air terjadi secara merata di kawasan tersebut. Kualitas perairan di lokasi penelitian masih sesuai dengan nilai baku mutu untuk kegiatan budidaya laut.Direct discharge of organic waste from aquaculture platforms is likely to increase nitrogen concentration in the surrounding waters. The study aimed to investigate the vertical distribution of total nitrogen (TN), total phosphorus (TP), and ammonia concentration in the coastal waters adjacent to the three densest mariculture sites in North Bali (Gerokgak, Penyabangan, and Kaping Bay). Field surveys were conducted six times within two periods namely April to June and August to October 2019. Samples of different water columns (surface, middle, and bottom) were collected using a Nansen water sampler in each sampling point. The samples were immediately analyzed at the Research Institute for Mariculture and Fishery Extension, Gondol. Total nitrogen, total phosphate, and ammonia were analysed using sulfuric acid destruction and distillation, nitrate-acid destruction, and phenol-spectrophotometer, respectively. The result showed that TN, TP, and ammonia levels were 1.2-1.5 mg/L, 0.081-0.090 mg/L, and 0.054-0.057 mg/L, respectively. The vertical distribution of nitrogen and phosphorus compounds at all layers of water column were relatively homogenous indicating a strong mixing between the seawater layers. Thus, the study concludes that the variations of all water quality parameters are within the water quality standard needed for mariculture activities.

Koto Panjang Reservoir is one of the hydroelectric power plants in Indonesia, located in Kampar Regency, Riau Province. This paper aims to determine the water quality and tropic status of the Koto Panjang Reservoir. The research was carried out along the Koto Panjang Reservoir, covering the floating net cages area, inlet, outlet, and the center of the reservoir. Water samples were collected twice a year, February and September 2017. The results showed that the water quality of Koto Panjang reservoir is still within the tolerance range for the aquatic organisms' life, including fish. Based on the TSI analysis, the Koto Panjang Reservoir throphic status was categorized as eutrophic to heavy eutrophic. This study recommends that relocating floating net cages is necessary so that the nutrient load will not only be concentrated in one location. The efficiency of using the feed for floating net cages could minimize the waste.
