Abstract The Sail River flows through the Pekanbaru City area which functions as a hydrological reservoir and main drainage channel. This river is affected by tides. Development along the Sail River Basin may affects the aquatic ecosystems. The research was conducted to determine the quality of the Sail River water and how it relates to the tides. Sampling was carried out two times during June-July 2021 in high and low tide conditions. The water quality parameters measured were temperature, TSS, pH, dissolved oxygen, BOD, COD, oil and fat, and Pb metal. Results showed that the temperature, COD, and Pb were significantly different at high tide and low tide conditions. On the other hand, during low and high tides condition, the value of TSS, pH, dissolved oxygen, BOD, oil, and fat were not significantly different. Dissolved oxygen levels during high and low tide ranged from 2.00 -3.00 mg/l and 1.00 -1.70 mg/l respectively. The Pb content during high and low tides ranged from 0.12-0.16 mg/l. In the present study, the values of dissolved oxygen and Pb content does not meet the water quality standards of Government Regulation No. 22/2021 (Class III).

Water quality is one of the crucial parameters in monitoring and evaluating watersheds. A large number of parameters causes the monitoring and evaluation of watershed performance to be less efficient and costly. This study aims to determine the main parameters as a method of simplifying water quality observation parameters by producing equations that can be used to predict the level of pollution of a non-point source pollutant (watershed). A sampling of surface water was carried out by purposive sampling at several outlets located in the Brantas and Upper Solo watersheds. The research parameters analysed were: TSS, TDS, BOD, COD, Phenol, Free Chlorineine, Sulfide, Arsenic, Fe, Pb, Phosphate, Nitrate, Nitrite, Detergent, Turbidity and E. Coli. The results of the analysis of water quality are used to calculate the value of the Pollution Index (PI) according to the Decree of the Minister of Environment No. 115 of 2003 and to determine the class of water quality standards that refer to Class III water quality standards, in Government Regulation No.82 of 2001. The analysis showed that all samples were at mild to moderate pollution levels, and did not meet class III water quality standards. Multiple regression analysis produced two equations, namely: Model 1: PI = 3.952 + 91.668 Phenol and Model 2: PI = 3.086 + 80.167 Phenol + 0.152 BOD, with R squared values of 53% and 69.9% with a confidence level of 0.005. Thus the prediction of pollution levels of similar watershed can be made only by using the two most influential parameters namely phenol and/or BOD alone.

The lack of clean water distribution by local water service (PDAM) of Palangka Raya city is the major reason for people around the final processing site/landfill (Tempat Pemrosesan Akhir) at Km 14 to use groundwater for their daily life. The landfill may cause pollution over groundwater known as leachate, which commonly unnoticed by its users. This study aims at assessing the quality of groundwater in that area. The groundwater was taken at different distances from the site in three rainless-days. The physical, chemical and biology parameters of groundwater are observed in the field (in situ) and analyzed in the laboratory, refers to water quality standard of Class I, according to Government Regulation No. 82 of 2001 and Minister of Health Regulation No. 32 of 2017. Public opinion on that issue is cached through interview. The results showed that the groundwater around the landfill in three rainless-days was harmless to be consumed as drinking water, and did not exceed the water quality standards stipulated by government in term of odorless, tasteless, and colorless. Some indicators also show that the groundwater meets the specified quality standards, i.e. TDS (17-68.14 mg/L), DHL (17,15-69.39 ?s), turbidity (0.11-2.50 mg/L), iron (0.227-0.71 mg/L), manganese (<0.0123-0.02 mg/L), coliform (<1.8-280 MPN/100 ml), while Pb and H2S were not detected. From community side, there are no any health complaints arise as long as they use the water.

The objective of this study was to determine the relationship between water drainage rates in Hit and Ramadi cities and the water quality of the Euphrates River. The studied area of Euphrates River extends from Hit to Ramadi, where two sampling stations were selected monthly in 2012, 2013, and 2018. The results indicate variations and decreasing in the monthly discharge rate of the study period; the year 2012 had higher discharge rate values than 2013, which in turn was higher than in 2018, for both gauging stations. Our results indicate that with decreasing discharge trends, some selected water quality parameters had an increasing trend. During the selected years, there was an increase in levels of sulfate, nitrate, dissolved oxygen, magnesium, and turbidity in the Ramadi station compared to the Hit station, as the rate of discharge of the river increases in the former. A positive significant correlation between discharge rate and dissolved oxygen and dissolved solids were reported. The Haditha Dam and its reservoir affect the downstream discharge rate and in turn the water quality at Hit and Ramadi Cities.

Rembagan River is the main tributary of the Bedadung River in Cangkring Village, Patrang District, Jember Region. Various community activities in the Rembagan River area such as bathing, washing, defecating and urinating as well as agricultural activities will produce domestic and agricultural waste. These wast can cause river water pollution, especially water quality degradation. then the research needs to be done an analysis of the capacity of the Rembagan River in receiving pollution costs. The purpose of this study is to find out how much the ability of the Rembagan River to accept the burden of pollutants using the Streeter-Phelps method. Streeter-Phelps modeling takes into account two phenomena, namely the process of measuring dissolved oxygen (deoxygenation) and the process of increasing dissolved oxygen (reaeration). The results obtained from these calculations are oxygen drop curves determined on the basis of oxygen deficit values. The average values of deoxygenation rate and reoxygenation rate were sequentially 1.58931 mg/L/day and 10.09982 mg/L/day. So that self-purification can run well which means the water quality of the Rembagan River was still relatively good. This can be seen in the DO model pattern that goes up in each segment. The actual DO of 5.6760 mg / L was greater than the DO standard of class III quality of 3 mg / L. It can be interpreted that the Rembagan River still has a remaining DO of 2.676 mg / L and was still able to accept pollution cost of 18.8 kg/day. Keywords:  pollution load, Rembagan River, river capacity

The decrease level of water quality of Brantas Watershed in Malang Raya was observed in this study. The aim of this study was to observe the decrease level of water quality of Brantas Watershed from Batu to Malang City. This study was carried out in the Brantas Watershed of Malang Raya (8 stations: A, B, C, D, E, F, G, and H) for 18,4 Km. The water quality parameters observed in this study were: CODmn (permanganometry), CODcr (CODmn correlation based analysis), dissolved oxygen (DO) (Winkler iodometry), TDS and electrical conductivity (EC) (EC meter), pH (pH meter), and turbidity (Turbidity meter). The result showed the value of CODmn: 1,8-10,2 mg/L, CODcr: 5,6-31,5 mg/L, DO: 4,0-6,1 mg/L, TDS: 204-289 mg/L, EC: 430-617 µS/cm, pH: 7,1-7,6, and turbidity: 2,02-10,30 NTU. There are 3 stations (A, B, and C) with 1st class water quality, 1 station (D) with the 2nd class water quality, and 4 stations (E, F, G, and H) with 3rd class water quality. The decrease of water quality in the Brantas Watershed from Batu to Malang City was up to 3 times with a decrease rate of 2,3 mg/L-1Km-1. The decomposition of organic materials in the water of Batu City and western part of Malang City is relatively better than that of central parts of Malang City which might be caused by the over capacity of recovery (Self-purification mechanism).

Abstract The water of Lake Rawa Pening is used as a source of drinking water. Indonesian Government Regulation Number 82 of 2001 on Management of Water Quality and Water Pollution Control stated that the water quality of Lake Rawa Pening should meet the quality standard of first grade and be categorized as no polluted water. The purpose of this research was to assess the water quality based on Indonesian regulation and to assess water quality based on international regulations. The quality of water was assessed using a survey method in 7 sites of the Lake Rawa Pening 3 times for 3 months. Parameters measured were all the water quality parameters required in accordance with Government Regulation No. 82 of 2001. The results indicated that there were 13 values that exceeded the water quality standard of first grade. These exceeded parameters were total suspended solids (TSS), biological oxygen demand (BOD), chemical oxygen demand (COD), orthophosphate (PO4), NO3, As, Se, Cd, Mn, Cu, Pb, H2S, faecal coliform, and total coliform. Water quality status of Lake Rawa Pening was categorized as heavily polluted. The water quality of Lake Rawa Pening should be improved by reducing the pollutants entering the lake by restriction of human activities causing lake pollution.
