Biological oxygen demand (BOD) is one of a parameter that has been widely
used to measure the quality of water. BOD is the amount of oxygen that needs
by a microorganism to decompose organic matter in water. This study is
conducted at Sungai Anak Telipot (SAT) because there is no official report and
continuous study has been done. The objective of this study is to investigate
the relationship between BOD and other parameters of water quality and to
determine the difference of water quality condition along SAT. For the physical
parameter, it is used handheld probe YSI Multi-parameters. Six parameters
listed in DOE-WQI was measured based on standard methods: pH, dissolved
oxygen (DO), salinity, biological oxygen demand (BOD), temperature and total
suspended solids (TSS). These parameters were sampled at five different
stations. From this study, it is concluded that BOD and DO has inversely
correlation because when BOD is high, DO is low.
