Abstract:
The Sub-DAS Riam Kiwa is a tributary of the Martapura upstream, which is often used by the
community to cover daily needs such as cooking, washing, and latrines. The current quality of
water condition of the Sub-DAS Riam Kiwa is estimated to have decreased caused by various
human activities on the riverbank. This study aims to determine the strategy of controlling river
water pollution. The river as a research area is set at 24.4 km. Water quality was measured and
observed at 3 sampling points then analyzed using the Pollution Index method. Analysis of
water pollution control strategies was using SWOT Analysis. The results showed that the Sub DAS Riam Kiwa was classified as moderately polluted with an IP value from upstream to
downstream of 7.88; 8.92; and 9.38. To maintain water quality in natural conditions a water
pollution control strategy is needed through diversification of existing strategies or programs
as a result of 1) strong internal factors including the monitoring of water quality, water quality
standards; and 2) the many threats from external factors which include the disposal of domestic
waste and livestock without recycling, the community does not have the knowledge of waste
and the community often violates government regulations.
