- Oxygen depletion in water bodies from biochemical processes is determined from the rate of carbon deoxygenation. Rate of deoxygenation carbon becomedeterminant variables in the calibration process of DO model. Several researchers have conducted deoxygenation carbon research for river outside Indonesia but is still limited to river in Indonesia. The study was conducted to determine the rate of deoxygenation of carbon in the Brantas river in Malang by using long-term BOD analysis and Thomas method. The results showed an increase in BOD value during the 30-day. The tendency is polynomial pattern orde 2 with the coefficient of determination, R2 of 0.9085-0.9596. Rate of carbon deoxygenation fluctuates from upstream to downstream with a range of values from 0.019 to 0.046 /day. While the value of BODuranges from 9.614 to 17.291 mg/L. The low rate of deoxygenation of the carbon indicates the low content of BOD of the river. Turbulent condition of river flow are also a factor to be considered oflow value of k. The results of calculations by themethod of Thomas has a coefficient of determination, R 2 is low (0.31 to 0.84). In this regard, the use of other methods such as the Least Square and Non Linear Regression should considAer in determining the value of the rate ofcarbon deoxygenation Brantas river in the city of Malang
