    (IOP Publishing, 2023) M R Zainudin; H W You; K E Lee; A M Zahidi
    This paper investigates the biochemical oxygen demand (BOD) and the pH level along Jelok River, Kajang, Selangor, Malaysia. The BOD and pH level are of major interest as microbial activity. Five water sampling locations along the river have been selected. To test the pH level of each water sample, a pH meter was used. To test the BOD of each water sample, the 5-days BOD test was conducted. Using the collected data, the Pearson' correlation coefficient between the pH and BOD was calculated.
