“…Ammonia is present in water in the form of ionized (NH4 + ) and ionized (NH3) The content of ammonia that is safe for aquatic life is less than 0.1 mg/l to below 1.0 mg/l [23]. The increasing phosphate concentration will affect the eutrophication of waters [19]. Eutrophication in rivers occurs due to the presence of nutrients.…”

Watersheds, especially downstream areas, are very important areas for the life of aquatic ecosystems. This downstream area is a coastal area which is a transitional area between land and ocean ecosystems. Several previous studies have shown that this area is polluted from industrial waste and domestic waste. Research sampling was conducted in the downstream watershed, Semarang Indonesia. Garang watershed is located in Semarang Regency as the upstream area and Semarang City as the downstream area. Sampling was carried out according to the regulation of the Governor of Central Java Indonesia 156/2010. This sampling was carried out in segment 7. Segment 7 according to their designation of Garang watershed which are settlements, estuaries, fisheries and loading and unloading ports. Water sampling in the downstream watershed. Samples for water quality analysis were taken in the downstream area of the river which is a coastal area. The results of the water quality analysis are compared with Government Regulation 82/2001. The results showed that the concentration of TDS, Copper and Chromium exceeded the quality standard. One of the analyzes used in the implementation of the ICZM is water quality, this is used for the maintenance of the downstream watershed area.

“…This phenomenon probably caused by strong water stagnant in the irrigation water due to irrigation system that unreliable. According to Salmani et al [18] TDS concentration is strongly influenced by water flow. Waste disposed from industrial activities affects the TDS value [19].…”

Danda Besar Swamp Irrigation Area (SIA) is located in Danda Jaya Village in Rantau Badauh District, Barito Kuala Regency, South Kalimantan Province, Indonesia. It is one of tidal swamp reclamation where tidal fluctuation of Barito River affects to the hydrological condition. Danda Besar SIA has potential agricultural land about 2, 200 ha, and the productivity of paddy field was only 2 ton/ha in average for each time planting year. Two ton/ha is too low productivity due to problem of water quality in irrigation canal. However, fundamental information for the management of water quality of irrigation, monitoring data of water quality, is not measured yet. This fundamental research was conducted to identify and analyze condition of irrigation water quality. The field survey was carried out in dry months, May and June 2021 at primary canal, secondary canal, tertiary canal and pond. The final result for 6 parameters of the 4 locations (primary canal, secondary canal, tertiary canal and pond) showed there were 3 parameters (TDS, DO, and Sulfate (SO4 2-)) fulfill the class II standard, meanwhile there were 3 parameters (pH, Iron (Fe) and BOD) not fulfill the class II standard according to Government Regulation No. 22 year 2021 regarding Implementation of Environmental Protection and Management. The high content of Iron (Fe) and low content of pH recorded in all water sources should be addressed with urgency since this phenomenon as a result of pyrite oxidation affect to pH condition and may cause the low productivity of paddy field.

“…TDS in the dry season ranges from 237-1,071 mg L -1 while in the rainy season ranges from 186-191 mg L -1 . TDS is strongly influenced by water flow, so that a decrease in water flow can increase the value of TDS (Salmani and Jajaei, 2016). Waste disposed from industrial activities greatly affects the concentration of TDS (Rohmawati et al, 2016).…”

Grenjeng River is one of the irrigation water resources which is currently polluted by waste from industrial, livestock and domestic activities. This study aims to assess the quality and index of water pollution based on physical-chemical and biological parameters in the Grenjeng River, Boyolali Regency. Sampling of river water was carried out in dry and rainy seasons which were taken at three observation stations (upstream, middle stream and downstream). Results from laboratory analysis were compared with water quality standards according to Government Regulation No.82/2001, and quality status was based on the Pollution Index method in accordance with the attachment to Minister of Environment Decree No.115/2003. This study shows that BOD of 53-5.7 mg L-1, COD of 49-510.5 mg L-1 and total coliforms of 540-2,400,000 mLin dry season have exceeded the quality standard water classes, while in rainy season total coliforms 24,000-240,000 mLhave exceeded the standard water for all water classes. The pollution index of the river water in dry season has reached polluted to extremely polluted levels and the index of the river water in rainy season has reached moderately polluted to polluted levels. This condition shows that the practice of dumping waste into river bodies can directly affect river water quality. The irrigation water source for agricultural must comply with irrigation water quality standards so that is suitable as irrigation water for plants. Environmentally friendly approach is needed to prevent worse pollution, which is done by increasing public awareness and business actors in managing liquid waste by making the integrated wastewater treatment system.
