Situ Gede is a natural small lake located in Kelapa Indah, Tangerang District, Tangerang City, which has an area of 5.07 hectares. The decreasing in water quality is characterized by the number of pollutants such as BOD (Biochemical Oxygen Demand), which are closely related to human activities such as the disposal by organic waste from domestic activities surrounding. The purpose of this study is to analyse the self-purification of water body in degrading of organic matter. The average of retention time of Situ Gede is 3.05 hours and a mixed concentration is 16.12 mg/l. The calculation results, the degradation rate at Situ Gede is 0.19/day. These results are stated as the composition of BOD in the Situ Gede situation not degraded perfectly. Alternative strategies for water pollution control can conduct by aeration to increase the oxygen for aerobic microorganism’s growth to process the organic matter degradation.
