AbstractRecognition of the deteriorating conditions of rivers worldwide has called for increased efforts to improve the ecological quality of impacted river systems. This is particularly important in areas that have suffered from a significant impact of human pressure on the ecological status of water. Field studies were conducted in the Ruda River in an area that had undergone anthropogenic disturbances. The objectives of our survey were to test the biological metrics based on benthic macroinvertebrates at four study sites. Spring and autumn surveys of benthic invertebrates indicated that based on the BMWP and BMWP(PL) indices, water quality was higher in comparison with the value of Multimetric index at all of the sites that were studied. Our results revealed that the water quality was higher at the study sites that are located above the dam reservoir based on both the chemical and biological parameters. This study also indicated that both spring and autumn constitute appropriate periods for carrying out monitoring studies. The values of multimeric index indicated the same water quality (except for site 1) in both sampling periods. Anthropogenic transformations of a riverbed influence the flora and fauna and affect the ecological status of rivers.

Jatiluhur Reservoir is one of the largest reservoirs in West Java which has many functions, one of which is for aquaculture with the KJA system. But along with the development of KJA activity in the Jatiluhur Reservoir it has become one of the factors causing the decline in water quality of the Jatiluhur Reservoir. Therefore the Purwakarta Regency government made a program called Operation Jatiluhur Jernih Lake through the Decree of the Regent of Purwakarta No.523.31.05 / Kep.286-DLH / 2017.  This program had a purpose to curb a number of cageculture in Jatiluhur Dam. The purpose of this study was to analyze the effectiveness of the program as an effort to save the condition of reservoir water and to analyze the impact of the program to the sosio-economic condition of the farmer. The methode that used in this study was quantitavie methode based on the effectivity value from the quisioner and the qualitative method by analyzing data from interview. the results of this study indicate that the Jatiluhur Lake Operations program is running quite effectively with the acquisition of a score of 60.37%, which means this program has a pretty good value in efforts to save the water conditions of the Jatiluhur reservoir. But on the other hand this program has a significant impact, especially on the socio-economic conditions of farmers such as decreasing income levels, rising potential for unemployment, increasing levels of difficulty in fulfilling the needs of life, and also reducing the supply of fish in the Jatiluhur Reservoir

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.

In-situ purification technology is used to improve the water quality of reservoir water, which uses the biofilm formed by enrichment microbes gathering on carrier system to purify water. Results indicate that total nitrogen and algae can be effectively removed, and the average removal rate of total nitrogen and the chlorophyll a is 18.1% and 25% respectively. The result of PCR-DGGE indicates that compared with the biological community in raw water, the biofilm on ecological carriers exhibit a more diverse population structure. Fluorescent pseudomonad which can effectively remove nitrogen and pseudomonas aeruginosa which can dissolve algae have formed stable microbial population structures in the in- situ purification area.

This study aims to determine the microbiological contamination in the main water source of the Muara Nusa Dua Reservoir, the Tukad Badung River, and to determine the microbiological quality of fresh Oreochromis niloticus caught in the Muara Nusa Dua Reservoir in Denpasar. The study was conducted in May-August 2019 at the Denpasar Veterinary Laboratory. The method used is a descriptive method that aims to describe or describe the condition of the Tukad Badung watershed which empties into the Muara Nusa Dua Reservoir (Estuary Dam). Objective tests include the total bacterial test, the Coliform test, and the Escherichia coli contamination test. Water quality measurements are also carried out as supporting data from this study. The results of the study stated that there was microbiological contamination in the water source of the Muara Nusa Dua Reservoir, the Tukad Badung river, which also had an impact on the waters of the Muara Nusa Dua Reservoir. Microbiological contamination research results showed the microbiological quality of ten samples of Oreochromis niloticus in the form of the highest total bacteria was at 2.2x104, the highest total Coliform was 1.9x104 and the highest Escherichia coli contamination was at 93 APM / g with an average reservoir water quality Muara Nusa Dua in the form of temperature 27.3 °C, salinity 0.208 ‰, degree of acidity (pH) 6.5, dissolved oxygen (DO) 5,97 ppm. Organoleptic observations included the appearance, smell, and texture of Oreochromis niloticus with good results because when testing Oreochromis niloticus is still alive

AbstractThe study on a small lowland river was conducted in order to determine changes in water quality under external loading (inflow of treated wastewater, runoff from agricultural areas) and the location of a dam reservoir in its course. The 21 km long River Pogona (Greater Poland, Poland) is a small tributary of the Obra Canal in Kościan. In 2004, in its valley, the Jeżewo Reservoir, with an area of 78 ha, was utilized to supply the flow in the Obra Canal during the dry season and to irrigate agricultural areas. The river is also a receiver of treated sewage from the sewage treatment plant in Karolewo. The research, carried out in 2017 at six sampling stations in its course, showed that the discharge of treated wastewater resulted in an increase in conductivity, concentration of ammonium nitrogen, nitrites and total nitrogen in the waters of the River Pogona. On the other hand, the location of the Jeżewo Reservoir in its course contributed to an increase in water temperature, pH, dissolved oxygen, chlorophyll-a and nitrite concentration in the outflowing river. The results showed that the inflow of treated wastewater from the sewage treatment plant, surface runoff from the catchment area and the Jeżewo Reservoir formed in its course, influenced seasonal and spatial changes in the water quality of the River Pogona.
