Balikpapan bay has an important and strategic role, such as a buffer for sustainability of the estuary function as the Balikpapan seaport. In Balikpapan esuary watershed there are large and small rivers, including Somber River. Settlements and industries around the river banks have caused a decrease of river water quality, especially activities that place pollutant loads (waste) on the river bodies. This research is focused on physical and chemical parameters, including Total Dissolved Solid (TDS), temperature, pH, and DO (Dissolved Oxygen).Water quality research was conducted by dividing the river into 7 measurment points. The distribution of measurement points was based on water quality considerations that represent upstream, middle, and downstream water quality, as well as considering easy access. Water samples at each mesurment point ware collected at three different depths (vertically). Concentrations of several parameters that have been obtained were then analyzed using the Pollution Index method (Pollution Index) which is used to determine relative pollutant levels to the allowed water quality parameters. The testing procedure by pollution index refers to procedure poured in the Decree of the State Minister for the Environment No. 115 in 2003 concerning of Determining Guidelines of Water Quality Status. Based on the field measurments, an average value for temperatures obtained ranging from 30.0 - 32.1 ° C, TDS values ​​4270 mg / L - 10000 mg / L, DO ranges between 1.8 mg / L - 3.1 mg / L, and pH values ​​between 6.6 - 7.1. From the calculation and data analisys of physical and chemical parameters, the research can be concluded that the location of measurement point 1 shows water quality status being lightly polluted, while point 2,3,4,5,6, and 7 shows water quality status being moderately polluted.

<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.

Lake Rawa Besar is an urban lake surrounded by dense settlements and commercial areas that are currently experiencing physical and ecological pressures due to uncontrolled land-use change around the lake. Therefore, this preliminary study aimed to investigate the sustainable management of the lake in order to create a recreational destination area. It was carried out by ascertaining the lake water quality status through the analysis of the physical and chemical parameters and identifying the potential pollutant sources due to land use and human activities. The physical parameters include TDS, TSS, Turbidity, while the chemical parameters include Nitrate-N, Total Phosphate-P, and BOD. Furthermore, field surveys on 30 water samples were conducted once at noon and statistical analysis was used to ascertain the correlation between the physical and chemical parameters. Finally, Geographic Information System (GIS) tools were used to investigate the spatial distribution of the Physico-chemical parameters and the potential pollutant sources. The results showed that based on the six parameters of the water quality status, the lake was lightly polluted. It also showed that three parameters such as Turbidity, BOD, and TSS exceed the permissible limit with 93.3, 66.7, 43.7% of the total samples, respectively. Additionally, a strong correlation existed between BOD and Turbidity with r=0.95, while a medium correlation existed between Nitrate-N and Phosphate-P with r=0.40. The spatial distribution of the concentration of the physico-chemical parameters generally had a varied pattern,  however, Turbidity and BOD had a similar pattern, especially in the bank areas. Finally, domestic and organic wastes were indicated as pollutant sources, which increased eutrophication in the lake.
