ABSTRAKSungai Cikijing termasuk ke dalam Sub DAS Citarik melintasi dua wilayah administrasi yaitu Kabupaten Sumedang dan Kabupaten Bandung. Sungai Cikijing menjadi sarana pembuangan air limbah dari aktivitas industri sehingga berpotensi menimbulkan pencemaran air sungai. Tujuan dilaksanakannya penelitian ini adalah menganalisis dampak pembuangan air limbah PT. X terhadap 3 aspek yaitu budidaya, kualitas air tanah dan tanah serta kesehatan masyarakat berdasarkan Peraturan Pemerintah Republik Indonesia Nomor 82 Tahun 2001. Kualitas air Sungai Cikijing pada Bulan Januari dan Agustus 2017 mengandung parameter yang tidak memenuhi bakumutu yaitu TSS, TDS, BOD, COD, Detergen MBAS, Belerang (H2S), Minyak dan Lemak, Nitrit, Nitrat dan Fenol. Pencemaran yang terjadi di Sungai Cikijing tidak berpengaruh terhadap penurunan kesuburan tanah, karena air Sungai Cikijing tidak dijadikan sumber air irigasi untuk lahan pertanian di lokasi sampling. Analisis kualitas air bersih di lokasi studi diambil dari 2 lokasi dengan membandingkan bakumutu sesuai Permenkes RI No. 492 Tahun 2010. Parameter air sumur di Desa Linggar yang tidak memenuhi bakumutu yaitu kekeruhan, Fe, Mn, dan Zat Organik (KmnO4). Sedangkan di Desa Jelegong parameter kekeruhan, pH, Fe, Mn, dan Zat Organik (KmnO4) tidak memenuhi baku mutu. Kualitas air sumur di kedua lokasi titik pemantauan tidak layak untuk di konsumsi harus dilakukan pengolahan terlebih dahulu sebelum dipergunakan untuk kebutuhan sehari-hari. Sungai Cikijing yang sudah tercemar dikhawatirkan dapat menurunkan kesehatan masyarakat. Data kesehatan masyarakat diperoleh dari Puskesmas Cisempur, Puskesmas Sawah Dadap, dan Puskesmas Rancaekek tahun 2015-2016 menunjukkan bahwa penyakit yang banyak diderita oleh masyarakat bukan sebagai akibat dari pencemaran air sungai Cikijing.Kata Kunci: Sungai Cikijing, Industri, PencemaranABSTRACTCikijing River is part of Citarik Sub watershed over two administrative areas of Sumedang and Bandung regencies. Cikijing river become a discharge media by industrial activity and thus potentially cause pollution of river water. The purpose of this research is to analyze the impact of waste disposal of PT. X against 3 aspects ie cultivation, groundwater and soil quality and public health based on Government Regulation of the Republic of Indonesia Number 82 Year 2001. Cikijing River water quality in January and August 2017 contains parameters that do not meet stream standard these are TSS, TDS, BOD, COD, detergents MBAs, sulfur (H2S), oil and fat, nitrite, nitrate, and phenol. Pollution that occurred in the Cikijing River has no effect on the decline in soil fertility because the Cikijing River water is not used as a source of irrigation water for agricultural land in the sampling location. The analysis of clean water quality in the study sites was taken from 2 locations by comparing standard according to Permenkes RI. 492 of 2010. Water well parameters in Linggar village that do not meet the standard these are turbidity, Fe, Mn, and organic substances (KmnO4). While in Jelegong Village, turbidity, pH, Fe, Mn, and organic (KmnO4) parameters did not meet the quality standard. The quality of the well water at both sites of the monitoring point is not feasible for consumption should be processed first before being used for daily needs. The polluted Cikijing River is feared to reduce public health. Public health data obtained from government public health facilities in Cisempur, Sawah Dadap, and Rancaekek in the year 2015-2016 show that the disease suffered by many people, not as a result of water pollution Cikijing river.Keywords: Cikijing River, Industry, Pollution

Water is very valuable resources that provide people and other living things. Besides the need for water for drinking, water resources play an important role in such as livestock, fisheries, water for irrigation and water recreation. However, water quality of the rivers may degrade due to the variation of land use as human activities increase. Cilutung watershed is dominated by the agricultural land use which in many studies shows that agricultural land use has a great impact on river deterioration. It does not affect only the physicochemical of water, the excessive amount of nutrient may harm the biotic ecosystem. The purpose of this study was assessing water quality of the rivers in Cilutung Watershed and the contributing factors using physicochemical and biological parameters. According to ANOVA and PPM calculations, water quality was affected by land use spatially and river discharge temporally. The overall results showed that the rivers were categorized as slightly polluted referring to WQI, BMWP, and Saprobic Index. In general, all water quality parameters measured in Cilutung watershed met water quality standard Class III as stipulated in Indonesia Government Regulation No. 82/2001. Therefore, water sources were still acceptable for fisheries, animal husbandry, and water for irrigation.

Studies about river water quality are essential since the decreasing of water quality could threaten hydrology watershed function. The objective of this study was to identify water quality in rainy and dry seasons of Cidurian watershed. Water quality data were obtained from Main River Basin Organization Territory Cidanau – Ciujung – Cidurian for 2018 and 2019. The parameters of water quality consist of total suspended solids (TSS), pH, dissolved oxygen (DO), chemical oxygen demand (COD), biochemical oxygen demand (BOD), phosphate (PO4), nitrite (NO2 – N), electrical conductivity (EC), temperature, Ca, and Mg. Water sampling location were in Jasinga (upstream), Neglasari (middle stream), Rancasumur (middle stream), and Tanara (downstream). The result showed that TSS concentration showed higher in rainy season than dry season in all sampling points with values higher than river water quality standard 50 mg/L. Therefore, need attention to adopt soil conservation practices in mixed tree crops, dry cultivation land, and crop plantation to decrease soil erosion. Downstream had values of pH, DO, COD, and BOD outside of water quality standards. Accordingly, government should issue some policies to protect from decreasing water quality. The information on river water quality in Cidurian watershed could support better watershed management for sustainable hydrology watershed function.

Water Conditions

Due to the surface water in the upper reaches of Yangtze River in China containing large amounts of silt and algae, high content of microorganisms and suspended solids, the water in Yangtze River cannot be used for cooling a heat pump directly. In this paper, the possibility of using Yangtze River, which goes through Chongqing, a city in southwest China, as a heat source–sink was investigated. Water temperature and quality of the Yangtze River in the Chongqing area were analyzed and the performance of water source heat pump units in different sediment concentrations, turbidity and algae material conditions were tested experimentally, and the water quality standards, in particular surface water conditions, in the Yangtze River region that adapt to energy-efficient heat pumps were also proposed. The experimental results show that the coefficient of performance heat pump falls by 3.73% to the greatest extent, and the fouling resistance of cooling water in the heat exchanger increases up to 25.6% in different water conditions. When the sediment concentration and the turbidity in the river water are no more than 100 g/m3 and 50 NTU respectively, the performance of the heat pump is better, which can be used as a suitable river water quality standard for river water source heat pumps.

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.
