“…Cikapundung River study that used laboratory observations for 10 days obtains the value of the deoxygenation rate ranges from 0.01 to 0.37 per day (Yustiani et al, 2018). A study at the Cicadas River water shows a deoxygenation rate ranging from 0.01 to 0.17 per day (Yustiani et al, 2019). Meanwhile, from Citarum River study, which was using the 30-day long-term duration method, obtained a deoxygenation rate value ranging from 0.37 to 0.45 per day (Yustiani et al, 2021).…”

River water quality modeling needs appropriate and suitable coefficients especially in application for specific river like urban river. Aim: This study aims to determine the value of the coefficient with a short term duration and a variable test time span. Several ways and methods of determining the rate of deoxygenation are developed according to the characteristics of the river and the environment. Modification method was applied in this research in which the test time span was unequal. The river chosen in this study is the Citepus River, Bandung, Indonesia representing an urban river in a tropical country. Methodology and Results: Sampling was carried out in the dry season. The laboratory analysis method used in determining the rate of deoxygenation uses the Slope Method of data from the short term incubation, which is ten days. The results showed that the Thomas Slope method's deoxygenation rate (K1) was 0.095 per day in the upstream segment, 0.917 per day in the middle segment, and 0.180 per day in the downstream segment. While the Ultimate BOD (La) value is 46.95 mg/l in the upstream segment, 38.70 mg/l in the middle segment, and 37.60 mg/l in the downstream segment. Conclusion, significance, and impact of study: The results of this study show that the value of the deoxygenation rate is similar to the theoretical surface water conditions. However, in the upstream segment, there is still a low deoxygenation rate value due to non-optimal activity of microorganisms. This findings will be very useful both in water quality modeling and river management.

“…BOD (Biochemical Oxygen Demand) of used water may reach 50mg/L (Alfiah et al, 2015). The water quality of urban rivers is indicated to be polluted, especially in densely populated areas (Yustiani et al, 2019). Utilization of used water from mosques is a good alternative as a substitute for river water use.…”

The role of water in daily life, including activities in the mosque is very significant. The existence of the Ulul Albaab Mosque which is always busy with various congregation activities and activities carried out by students and the campus community affects the need for clean water. So far, the ablution used water at the Ulul Albaab Mosque has been dumped into the sewers. Measuring the quantity of water to determine the volume of ablution used water at the time of obligatory prayer is the first step to assessing its potential utilization. The number of congregation who perform ablution is directly proportional to the number of congregation of the Ulul Albaab Mosque. The average congregation of the mosque is 857 people/day and the average number who perform ablution is 778 people/day. The results showed that the volume of water used for ablution was 3.9 liters/person with an average time required for ablution of around 64 seconds. The use of recycling ablution water can be used for non-consumption needs.

“…Jika kecepatan aliran tinggi dan profil hidrolik sungai yang dangkal maka nilai konstanta reoksigenasinya juga besar. (Yustiani et al, 2019). Keuntungan yang akan diperoleh apabila laju reoksigenasinya besar maka paparan oksigen terlarut pada badan air tersebut relatif cukup dalam dekomposisi bahan organik secara alami di Sungai Gunung Pasang.…”

Gunung Pasang River is as raw water supply for the human activity. However, it is utilized as waste disposal from community activities, agro-tourism, and rubber factories. These activities have the potential to reduce water river quality. The efforts to river pollution prevention that can be taken are to examine for capacity of the rivers to reduce pollutant naturally. The research focused to analysis the pollution load, oxygen dissolved distribution (deoxygenation and reoxygenation rate), and the total pollution load of the Gunung Pasang river utilized the Streeter-Phelps formula. The study was conducted in November – December in 2019 at the Gunung Pasang River with a river length of 300 m which was divided into 3 segments with 4 monitoring points (GP01, GP02, GP03, GP04). Analysis of the parameters i.e. DO and BOD to measure the water quality degradation in the river and the resulting graph of oxygen reduction. The method refers to Minister of the Environment Decree no. 110/2003.The results showed that the average pollution load value was 6.32 kg/day. The range of deoxygenation and reoxygenation rates is 2.67 - 5.36 mg/L.day and 32.77 - 64.71 mg/L.day respectively. The Reoxygenation rate was greater than deoxygenation. This phenomenon reflected that the Gunung Pasang River has a good self – purification performance. The average pollution load capacity of the river is 2.17 kg/day.Keywords: total pollution capacity; oxygen distribution; self – purification; water quality monitoring.
