ANALISIS KUALITAS AIR SUNGAI SARIO KECAMATAN SARIO MANADO  SULAWESI UTARAABSTRAK Penelitian ini dilakukan untuk menganalisis kualitas air sungai Sario berdasarkan sifat fisika dan kimia sesuai dengan PP No 82 Tahun 2001. Penelitian dilakukan di laboratorium Baristand Industri Manado pada bulan November 2015, dengan 4 sampel air yang diambil pada 4 titik dari hulu sampai hilir sungai Sario Kota Manado menggunakan 7 parameter yaitu kekeruhan, pH, nitat, nitrit, BOD, COD dan DO. Hasil penelitian ini menunjukkan bahwa kualitas air sungai Sario yang sesuai dengan ambang baku mutu air berdasarkan PP No. 82 Tahun 2001 hanyalah pada bagian hulu sampai tengah Sungai sebelum memasuki wilayah Kota Manado, sedangkan pada sekitaran hilir sungai Sario telah tercemar yang berhubungan dengan aktivitas masyarakat dengan diindikasikan berdasarkan konsentrasi BOD, COD dan DO yang buruk dan tidak sesuai dengan ambang baku mutu air berdasarkan PP No. 82/2001. Kata kunci : Kualitas Air, Sungai Sario   ANALYSIS OF RIVER WATER QUALITY SARIO DISTRICT MANADO  NORTH SULAWESI ABSTRACT This study was conducted to analyze the Sario river water quality based on physical and chemical properties in accordance with PP No. 82 of 2001. The study was conducted in laboratory Baristand Industry Manado in November 2015, with four water samples taken at 4 points from upstream to downstream Sario City Manado using 7 parameters: turbidity, pH, nitat, nitrite, BOD, COD and DO.  The results of this study indicate that the water quality in accordance with the Sario river water quality standard threshold under PP No. 82 of 2001 only on the upstream side to the middle of the river before entering the city of Manado, whereas the downstream Area Sario river has been polluted related community activities to be indicated by the concentration of BOD, COD and DO poor and not in accordance with the water quality standard threshold based PP No. 82 of 2001.

This paper explained heavy metals and chemical properties from the Cisadane River in Tangerang City. A survey method was used to determine the place for sampling the test material. Water measurement is carried out in situ and laboratory tests. Data retrieval was done by purposive sampling determining three observation stations, namely in the Taman Gajah Tunggal park area (station1), Babakan Cikokol residential area (station 2), and Karawaci paper mill area (station 3). The analysis was carried out exactly using analysis. Namely, analysis carried out in the laboratory. The parameters observed were COD, phosphate, DO, BOD, pH. Results of this study informed the water quality in the Cisadane City river did not meet Class II Water Quality Standards based on Government Regulation Number 82, the year 2001. The COD content only meets class II water quality standards at stations 1 and 3. BOD and phosphate content is high and exceeds class II water quality standards. Heavy metal content still meets the water quality standard threshold with a value of Cd less than 0.01 mg/L, Cu less than 0.02 mg/L, Pb less than 0.03mg/L, and Cr less than 0.05mg/L. Zn content exceeds the water quality standard threshold at station three and meets water quality standards at stations 1 and 2 with a value of less than 0.05mg/L.

Water Quality Standard

Cimanuk river is one of the seven rivers in West Java. Cimanuk river pollution is indicated to have suffered as a result of the activity of domestic waste, industrial and agricultural uncontrolled in the riparian area of Cimanuk river. This research aims to analize water quality of Cimanuk river based on water quality standard on Government Regulation of Republic of Indonesia (IDN), Regulation of the Governor of West Java (WJ), World Health Organization (WHO), Enviromental Standard of United Kingdom (UK), Environmental Protection Agency (EPA), Enviromental Quality Standard (EQS), and Department of Environment (DOE). This research used pollution index method. The result is water quality of Cimanuk river not meet water quality standard where the TSS (94.85±84,60 mg/L), BOD (9.61±3.16 mg/L), COD (37.69±14.01 mg/L), DO (5.12±1.22 mg/L), NH3N (0.25±0.24 mg/L). Degradation of water quality of Cimanuk river from upstream to downstream marked by increased pollution index value annually. Pollution index of Cimanuk river ranging from 1.25 to 20.31. Water quality status of Cimanuk river has been from lightly polluted to heavilypolluted.

Grey Relational

In order to evaluate the water quality of Longjiang river comprehensively, diatoms of 15 sampling sites are collected to establish the Grey Relational Model based on three diatom indexesIPS, IBD and IDG. From the Cluster analysis of sampling sites and the box plot of diatom index, IBD is the best, then the IPS, the diatom index weights on water quality assessment are 0.637 for IBD, 0.2583 for IPS, 0.1074 for IDG respectively. Finally, by comparing the water quality standard level based on Grey Relational Model, it can be known that the water quality of most sampling sites is fine except that site No.1 and No.3 belong to III water quality standard. The result shows that it is more comprehensive and reasonable to use the Grey Relational Model based on diatom index rather than individual diatom index to assess water quality.

Polymer flooding has became one of the most important oil recovery technologies with Chinese oilfields coming into tertiary recovery, which lays a solid foundation for high and stable yields in oilfields. But with it’s large-scale industrial production, polymer flooding technology also brings difficulties for the disposal and treatment of polymer flooding wastewater. Compared with conventional water flooding wastewater technology, polymer flooding wastewater not only contains oil but also lots of polymer. “Old three sets” process cannot meet the national discharge standard or the injection water quality standard. Relied on HeNan oilfield united station, this paper studied on the treatment of polymer flooding wastewater, a kind of efficient flocculant was selected for the treatment of polymer flooding wastewater and a set of reasonable technological process was recommended, making the wastewater after disposal meet the injection water quality standard.
