DO at each site from high to low value, so there are 2 Site up as high as possible on Site, Site 3 is 1, 4, and 5 Site Site, respectively, with a value of 7.46 7.33, 6.60, 6.30 and 7.10, mg/L, respectively. DO values indicate the oxygen dissolved in the water. If the value is greater than 6.0 mg/L, so the water quality of each Site are (when using only DO) from table 2 that there Site .... DO as highest values may be caused by Site area area there are 2 styles fai slow water above the River, thereby increasing oxygen levels in the water, river water is also fairly shallow. The oxygen from the air to get more water. The second Site, which seems to be the assumption 1 is the highest, but DO the experiment Site is less than 2, this may be a result of how the flow of water at water level 2 Site slower and deeper than it affects less Aeration.
