Turnitin_ANALYSIS OF WATERSHED CARRYING CAPABILITIES BASED ON POLLUTION LOAD CARRYING CAPABILITIES OF THE RIAM KANAN SUB-WATERSHED, SOUTH KALIMANTAN PROVINCE, INDONESIA

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.
