摘要：Remu River has been a water resource for residents in Sorong City. Development in this city leads to water
quality degradation of Remu River. Existing (2016) and prediction condition of Remu River in the next two years were
defined by the behavior of BOD, COD, Fe, and DO that proceed using a dynamic program, STELLA 9.1.3. Study area
involved six sampling points. Simulation results showed that BOD, COD, and Fe concentrations tend to increase in the next
two years, even BOD and COD concentrations at several sampling points were higher than water quality standard,
according to Government Regulation No. 82/2001. Meanwhile, DO concentration was below the limit in 4th to 6th sampling
points. The pollution control strategy was conducted by setting up three scenarios: (1) procurement of Waste Water
Treatment Plant (WWTP), (2) river sediment dredging, and (3) combination of both scenario. Combination of sediment
dredging and procurement of WWTP scenario estimated to reduce BOD concentration to 89.82%, COD concentration to
87.02%, and increase DO concentration to 19.07%. So, the 3rd scenario was determined as the best strategy to improve
Remu River water quality, although Fe concentration cannot be controlled as it comes from nature.
