Water pollution because of the domestic wastewater produced by the local community and their home industries in a big city, such as Jakarta, has already been inviting many environmental problems since the last ten years. Based on the research done by Directorat General Cipta Karya, Public Works Department RI, domestic wastewater in Jakarta delivers 75% of all pollutants in surface water pollution. Therefore many things should be done to solve those water pollution problems. A lot of environmentally related rules have established in Indonesia, but they are not able to be optimally implemented because of some weaknesses of the environmental rule contents. One of the solving options is to create a perfect regulation system for wastewater management. The laws for home industry wastewater management, especially in big cities, have to be perfectly completed, mainly in the field of standard, operation and procedure, the wastewater quality standard, the adequate and qualified technology, the landscape and building planning and the institutional coordination. If the all environmental regulations are well synchronized, the law enforcement will be simply implemented. By applying them consistently, the water pollution control will be handled well. Keywrods : Environmental Regulation, Home Industry Waste Water, Institutional Coordination

The regulations said that all domestic wastewater first should be treated before being discharged into public drainages. Therefore, IMERI building, as a research and education building located in the Faculty of Medicine, Universitas Indonesia, applies a wastewater management system using activated sludge technology combined with microorganism biofilters. This system is expected to treat the waste generated inside the building. It reprocesses become recycled water and partially discharged into city drainages based on the quality standard and maintenance applied during the operation. By collecting and evaluating primary and secondary data from system planning and routine maintenance results, we assess all performance of the WWTP system. Moreover, this system runs well and has all indicators of effluent categorizes safe. However, routine maintenance and the treatment process with chlorination and tighter monitoring should be taken seriously to keep the whole system's performance.

Surface water sources play an important role in human and biological activities and the socio-economic development of the region. Therefore, the assessment of water quality and determination of the causes of water pollution in Sao river is essential for good management of the surface water environment. The study was conducted from July to December 2020. Water samples were collected at the time of low tide to evaluate the water quality indicators of temperature, pH, conductivity (EC), dissolved oxygen (DO), biological oxygen demand (BOD), total suspended solids (TSS), ammonium (N-NH4+), orthophosphate (P-PO43-) and coliform. The source of pollution was determined by direct interviews with households living near Sao river. The results showed that surface water quality in Sao river had signs of organic pollution and microbiological pollution due to BOD, TSS, N-NH4+, P-PO43-, coliform exceeded the allowable limits of National Technical regulation on surface water quality (QCVN 08-MT:2015/BTNMT, column A1). The results of the interview revealed that 70% of respondents said that water was seriously polluted and the main sources of pollution were domestic solid waste and domestic wastewater. Therefore, to improve surface water quality in Sao river, solid waste and wastewater management is urgently required. It is necessary to promote the monitoring and management of water quality with the participation of local authorities and communities.

Water pollution during festival periods is a major problem in all festival cities across the world. Reliable prediction of water pollution is essential in festival cities for sewer and wastewater management in order to ensure public health and a clean environment. This article aims to model the biological oxygen demand (BOD5), and total suspended solids (TSS) parameters in wastewater in the sewer networks of Karbala city center during festival and rainy days using structural equation modeling and multiple linear regression analysis methods. For this purpose, 34 years (1980–2014) of rainfall, temperature and sewer flow data during festival periods in the study area were collected, processed, and employed. The results show that the TSS concentration increases by 26–46 mg/l while BOD5 concentration rises by 9–19 mg/l for an increase of rainfall by 1 mm during festival periods. It was also found that BOD5 concentration rises by 4–17 mg/l for each increase of 10,000 population.

Potential Pollution

Sasirangan - the traditional fabric, claimed as an icon of Banjarmasin and core part of South Kalimantan identity - has been produced for a long time by home industries and contributes to local community economic development. Practically, activities of Sasirangan home industries use several chemical coloring agents that produce liquid waste and harm the ecological life of the Martapura River in Banjarmasin. The purpose of this study is to identify the potential of liquid waste of sasirangan for pollution in the Martapura River. Certainly, It would importantly contribute to providing a solution to overcome these waste effects on the surrounding environment. This study used the observation method and survey approach to the Sasirangan home industry in three locations around the Martapura River in Banjarmasin City. Sampling was conducted both at the point of the inlet and outlet of these locations. Then, the samples were laboratory tested and quantitatively analyzed for biological parameters (total Cr and total Cd content in Snakehead Fish) and chemical parameters (BOD, COD, and content of oil and fat). The results showed that the wastewater content of sasirangan generally was still within the limits of quality standards permitted according to the Governor of South Kalimantan Regulation Number 04 the Year 2007. Nevertheless, there were still several parameters that exceed the quality standard, for the content of heavy metal chromium in Snakehead Fish with a value of 0.456 mg/kg and COD parameters of the upstream sample inlet with a value of 348.9 mg/L.

Rivers are the lifeline of Bangladesh economy and serve as the source of water supply, fisheries, irrigation for agriculture, low-cost transport, generate electricity and conserve biodiversity. The Ichamati River situated in Pabna, Bangladesh is also a blessing for the city. However, recently, due to the irregular and unplanned activities adjacent to the riverside, the life, flow and water quality of the river is in a vulnerable condition. This study aims to identify the present status of the Ichamati River and provide an effective design approach and policy measures in restoring the river flow and control water pollution. The data was collected from the questioner surveys, key informant interviews and focus group discussions. Results suggest that several factors such as the construction of an illegal settlement, unplanned waste dumping, disposal of fiscal sludge through sewerage connection, lack of awareness among people regarding the importance of river biodiversity and absence of riverfront development and conservation plan are responsible for water pollution, inconsistent water flow and damaging the life cycle of Ichamati river. The design approach and policy measures were developed based on the perceptions of local community people, experts and government officials. The suggested policy measures will help to restore the flow of the river and reduce the water pollution, and the design approach will ensure the economic benefit of the riverfront development in future.

Japan experienced serious water pollution during the period of high economic growth in 1960s. It was also the period that we had such damages to human health, fishery and living conditions due to red tide as much of chemicals, organic materials and the like flowing into the seas along the growing population and industries in the coastal areas. Notable in those days was the issues of environment conservation in the enclosed coastal seas where pollutants were prone to accumulate inside due to low level of water circulation, resulting in the issues including red tide and oxygen-deficient water mass. In responding to these issues, we implemented countermeasures like effluent control with the Water Pollution Control Law and improvement/expansion of sewage facilities. In the extensive enclosed coastal seas of Tokyo Bay, Ise Bay and the Seto Inland Sea, the three areas of high concentration of population, we implemented water quality total reduction in seven terms from 1979, reducing the total quantities of pollutant load of COD, TN and TP. Sea water quality hence has been on an improvement trend as a whole along the steady reduction of pollutants from the land. We however recognize that there are differences in improvement by sea area such as red tide and oxygen-deficient water mass continue to occur in some areas. Meanwhile, it has been pointed out that bio-diversity and bio-productivity should be secured through conservation/creation of tidal flats and seaweed beds in the view point of “Bountiful Sea” To work at these challenges, through the studies depending on the circumstances of the water environment in the enclosed coastal seas, we composed “The Policy of Desirable State of 8th TPLCS” in 2015. We have also added the sediment DO into the water quality standard related to the life-environmental items in view of the preservation of aquatic creatures in the enclosed water areas. Important from now on, along the Policy, is to proceed with necessary measures to improve water quality with good considerations of differences by area in the view point of “Beautiful and bountiful Sea”.
