Abstract

Bedadung River is the main river in the Bedadung Watershed in Jember Regency. People use the river to fulfill their daily needs and agricultural irrigation. Organic pollutants from domestic wastewater and agriculture wastewater that enter in river can decrease dissolved oxygen concentration, which can influence the river’s water quality. The river has a self-purification system with a reaeration and deoxygenation mechanism. The purpose of this study was to analyze the rate of deoxygenation and reaeration using the Streeter-Phelps method. Deoxygenation and reaeration rates influence oxygen concentration. This research took water samples using a Grab Sampling technique as the primary data at 5 nodes and 4 segmentations. The results of the research showed that the deoxygenation rate was 0.036 mg/L.day and the reaeration rate was 0.046 mg/L.day. This meant that the deoxygenation rate was lower than the reaeration rate so the self-purification can run quite well. The average DO value was 7.62 mg/L, showed that the river according to the class III water quality standard, so, the water quality was good and save to be used by the public. The research result can be used to determine the water quality carrying capacity in the next research.

Abstract

The Antirogo River is a tributary of Bedadung Watershed which flows from Tegal Gede Village to Sumbersari Village, Jember Regency, East Java. The land areas near the River is used for agriculture, residential settlements, and industry. The wastes dumped from these lands degrades the water quality. Therefore, this study aimed to determine the river capacity against pollution loads, using the Streeter Phelps method in accordance with the Decree of Environment State Minister No. 110 of 2003. Water samples was taken from the River and divided into four monitoring points namely ATR01, ATR02, ATR03, and ATR04. A purposive sampling method was used and the water quality was analyzed. The average pollution load is 70.37 kg/day. Furthermore, the highest load is 81.04kg/day at ATR03 and the lowest is 64.81 kg/day at ATR04. Therefore, the river’s capacity can be determined by calculating the reaeration and deoxygenation rate, critical oxygen deficit, distance, and time taken to reach a point. The average deoxygenation rate is 1.77 mg/L.day, and that of reaeration is 16.13 mg/L.day. Also, the DOact values at ATR01, ATR02, ATR03, and ATR04 were 6.59 mg/L, 6.67 mg/L, 6.63 mg/L, and 6.67 mg/L respectively. The average value of oxygen deficit is 1.19 mg/L. According to the values of deoxygenation, reaeration, oxygen deficit, and DOact, it can be interpreted that the river is not in a critical condition, and, therefore, can tolerate pollutant load of 7.26 kg/day.
