Abstract:
Research was carried out for 6 (six) months in the waters of the Riam Kanan Sub-Watershed
located in Banjar Regency. The Riam Kanan sub-watershed is an ecosystem that is
important for the life of living creatures and the surrounding environment. Data related to the
resources contained in rivers is very necessary for more precise management, which
currently is very limited. The increase in population every year and rapid economic
development cause environmental problems related to the use of water resources. It is
necessary to assess the condition of the water system for monitoring river watersheds to
prevent various environmental problems. The aim of this research: (1) Analyze water quality
(pH), temperature, depth, NO3, PO4, NH3, E. Coli, BOD, and TSS Mn and Fe) based on the
Pollution Index and Water Quality Index; (2) Confirming the Carrying Capacity of the Riam
Kanan Sub-Watershed, South Kalimantan Province. The results of the analysis of water
quality parameters found that the Pollution Index was lightly polluted at the Riam Kanan
Subwatershed observation station and the results of the calculation of the Water Quality
Index were included in the medium category; The results of calculations regarding the
pollutant load capacity contain several parameters that exceed the quality standards, namely
parameters; Phosphate, Fe, DO and BOD.
