A study on water quality status of three riverine systems, S. Bailang (SB), S. Maasing (SM), and S. Tondano (ST), in coastal city of Manado, North Sulawesi Province, has been conducted to measure several water quality parameters, to analyse source and quality of wastewater discharge, and to assess the status of the rivers related to the water quality. Measurement of the parameters was conducted using three indicators, i.e. organic (BOD5) and in-organic (N-NO3 and P-PO4), and pathogenic microorganism (Escherichia coli [EC] and total coliform [TC]). The result showed that the level of water quality varied between the rivers. The average level of water quality (based on the observed parameters) in SB, respectively, was 0.317 mg/l, 0.093 mg/l, 2 mg/l, >2420 MPN, and  >2420 MPN; in SM, respectively, was 0.029 mg/l, 1.859 mg/l, 17.7 mg/l, >2420 MPN, and >2420 MPN; and in ST, respectively, was 0.299 mg/l, 0.252 mg/l, 3.5 mg/l, >2420 MPN, and >2420 MPN. The level of water quality between the rivers was not significantly different (p>0.05), except based on the parameter of N-NO3 which was significantly different (p<0.01). The status of the observed rivers varied based on the classes of their water utilities (according to the Government Regulation of Indonesia, No. 82, 2001); mostly was "unsuitable". Kajian tentang status kualitas air di 3 perairan sungai di kota pesisir Manado, S. Bailang (SB), S. Maasing (SM), dan S.

Cibaligo River is the polluted rivers in Cimahi City. The river that flows through three districts and 6 sub-districts in Cimahi City catchment  area of 666.19 hectares of watershed with a total length of 7 km. The land use of the district through which this river passes is domestic, trade, agriculture, livestock and industry whose waste will end into the Cibaligo River. The impact of these activities causes the river to be polluted and a decrease in water quality. The purpose of this study was to determine the status of water quality from upstream to downstream which represents the transition, dry, and rainy seasons. Knowledge of water quality status can be used as basic data for controlling water pollution in rivers. The pollutant index (IP) method used in this study is in accordance with the Decree of the State Minister for the Environment Number 115 of 2003 concerning guidelines for determining water quality status. The results showed that the water quality status of the Cibaligo River from upstream to downstream represented that each season was categorized as heavily polluted with the highest index value being in the rainy season at the downstream point. The main contributor that causes river water to be heavily polluted is domestic wastewater, especially the presence of total coliform and fecal coliform that exceed the established quality standards. Based on the results of the research, efforts to tackle domestic waste are needed to improve the quality of this river water.

Kondisi kualitas air suatu perairan yang baik sangat penting untuk mendukung kehidupan organisme yang hidup di dalamnya. Penentuan status mutu air perlu dilakukan sebagai acuan dalam melakukan pemantauan pencemaran kualitas air. Penelitian ini bertujuan untuk mengkaji status mutu air laut berdasarkan konsentrasi parameter surfaktan dan minyak di perairan Distrik Depapre, Kabupaten Jayapura. Pengambilan sampel air laut dilakukan di lima stasiun penelitian, kemudian hasilnya dibandingkan dengan baku mutu air laut untuk biota laut berdasarkan KEPMEN-LH No. 51 Tahun 2004. Hasil penelitian menunjukkan bahwa konsentrasi surfaktan di perairan Distrik Depapre berkisar antara 0,08–0,22 mg/L, sedangkan konsentrasi kandungan minyak berkisar antara 0,14–0,41 mg/L. Berdasarkan baku mutu air laut, konsentrasi surfaktan dan minyak belum melampaui baku mutu dan masih sesuai untuk biota laut di perairan Depapre, Kabupaten Jayapura. Hasil penelitian ini memberikan informasi bahwa kondisi perairan Depapre belum tercemar oleh limbah surfaktan dan minyak. Namun tidak menutup kemungkinan bahwa konsentrasi tersebut dapat terus meningkat, sehingga perlu upaya lebih lanjut dari pemerintah dan masyarakat untuk meminimalkan jumlah limbah surfaktan dan minyak yang masuk kelingkungan perairan laut. Good water quality is critical to support the life of organisms. The determination of water quality status was needed as a reference to monitor water pollution. This study aimed to assess the condition of water quality based on the concentration of surfactant and oil parameters in the Depapre waters, Jayapura Regency. Sampling was carried out in five research stations; then the results were compared with water quality standards based on KEPMEN-LH No. 51 Tahun 2004 for marine biotas. The result showed that the concentration of surfactant in Depapre waters was 0.08–0.22 mg/L, while the oil concentration was 0.14–0.41 mg/L. Based on water quality standards, surfactant and oil concentration has not exceeded the quality standards and are suitable for marine biotas in Depapre waters, Jayapura Regency. Results showed the condition of  Depapre waters had not been polluted by surfactant and oil waste. However, it does not rule out the possibility that the concentration can increase so that it needs further efforts from the government and the community to minimize the amount of surfactant and oil waste entering the marine environment.

<strong>Aim:</strong> The purpose of this study was to determine the status of water quality in a river by using the Pollution Index method as stated in the Decree of the Minister of Environment No. 115/2003 regarding Guidelines for Determining the Status of Water Quality and to determine the effect of quality status on development efforts towards ecotourism. <strong>Methodology and Results:</strong> The measurement of water quality was carried out at two points, namely T1 (upstream) and T2 (downstream) points. The parameters included BOD, COD, DO, TSS, Temperature, pH, Zn, S, P, No3, and No2. From the test results for class I, II, and III criteria, almost all parameters exceeded the quality standard. The status of the river water quality, according to the Pollution Index, has increased from moderate polluted upstream and heavily polluted to certain parameters downstream. <strong>Conclusion, significance and impact study: </strong>The quality standards that are met for the river are criteria for class IV. The increase in pollution is indicated by human activity around the river which is characterized by increasing population and land use in agriculture and plantations. The increasing pollution reduces the quality of the river if it is developed into an ecotourism area due to its low water quality status.

Setyono P, Himawan W. 2018. Analyses of bioindicators and physicochemical parameters of water of Lake Tondano, North Sulawesi Province, Indonesia. Biodiversitas 19: 867-874. The water quality of Lake Tondano is affected by various anthropogenic activities on the water body and catchment area. The purposes of this research were (i) to identify a pollution load based on the study of bioindicators and physicochemical parameters and (ii) to identify the trophic level of the Lake Tondano. The research data were collected by direct water sampling and analyses of a secondary data. The plankton identification was conducted in a laboratory. The data were analyzed to determine biodiversity index (ID) using the Shannon Weiner formula. A comparison between physicochemical parameters and the standard in the government regulation number 82, the year of 2001 and the value of diversity index were used to determine the pollution level. The trophic level was calculated with the Carlson Formula. The results showed that the diversity index (H') in Lake Tondano was 1.904 (phytoplankton), 1.712 (zooplankton) and 2.086 (benthos) which indicated a low to mid-level pollution. Based on the government regulation, the Eris station had inappropriate water quality for the present utilization (Class II). The trophic state was categorized as eutrophic towards hypertrophic condition indicated by domination of the phytoplankton and large covers of the water hyacinth.
