Abstract

Banyuasin Regency, which part of its territory is tidal land, like the Gasing River. The data used secondary data using SPSS. Most of the results of pH measurements were the range 2.82 - 5.75. The COD parameters are all above the quality standard. For TDS, DO, BOD, and TSS all are still below the quality standard. Heavy metal parameters such as Fe-T of the year there are concentrations of more than the quality standard. In addition, Cu-T is all above the quality standard. Results of comparative analysis of water characteristics at pH, temperature, TDS, DO, BOD, COD and TSS. The results of comparative analysis of Zn-T, Fe-T, Cd-T, Pb-T, and Cu-T found no differences in all conditions. The moderate pollution index was found in the downstream part of the April 2017 measurement of 6.54. While other data shows a light pollutant index with a value range of 1.17-4.80.
