ANALISIS TINGKAT PENCEMARAN POSFAT DAN NITRAT DI BEBERAPA SUB DAS KALIMANTAN SELATAN

Abstract

This study aims to determine the pollution levels of nitrate (N) and phosphate (P) in South Kalimantan Several subzone based method Pollution Index (Kep_MENLH /115/2003). The results were obtained relationship (r) between the variables Quality Standards(Y1) and variable (X) or Phosphate and Nitrate = 0.792. Calculation of the value of R2-determinant obtained yield was 0.672. This means that 67.2% factor Water QualityStandard (Y) is influenced by factors Phosphate and Nitrate, while the remaining 33.8%is influenced by other variables that can not be explained in the equation. The ratio between the parameter P and N (P = 0.577 N = 0,062 = 9.30), is between 7 to 12. It means that the variable Phosphate and Nitrate is not a limiting factor for contamination.Calculation results of the pollution index pareameter P and N obtained a value of 9.30,still meet quality standards for some sub-sub-basins (Riam Kanan, Tabanio, Naiyan River, River Satui, Kintap River, and the River Sebamban).
