Abstract
Cikapundung River is the main river that located in the middle of Bandung City. It has polluted water due to the surrounding condensed houses and domestic-non domestic activity. The changing of the discharge pattern due to the climate uncertainty makes the difficulty to perform the river quality assessment. One method to assess the river water quality is by means of simulation results of a model verified with the measurement data obtained from in the field. Modeling is a method that is easy, inexpensive, and saves time. The use of river quality model is very useful to predict the future condition using kinds of scenarios, so that the river environmental management can be formulated prior to the occurrence of pollution, environmental damage, or other disasters. Modeling of river water quality was introduced by Steeter Phelps equation using oxygen depletion curve equation (oxygen sag curve) which is using coefficients, i.e. deoxygenation rate and reaeration rate. These rates are environmental condition depended values; therefore the specific research to find the suitable rates is needed. Furthermore, to make simulation simpler, the development of software of river water quality model is necessary. The ‘KUALA.V0 1’, software to simulate BOD and DO of river water is now being designed enriched with local water characteristic. Laboratory analysis was conducted to obtain the deoxygenation rate. The software was then being tested. The model gave that the value of deoxygenation rate using laboratory analytical methods ranged from 0.01 to 0.37 per day and ultimate BOD ranged between 1.17 to 6.44 mg/L. The software gave reasonable result in its application to simulate the Cikapundung River water quality. Keywords: BOD decay rate; deoxygenation; urban river water quality
