Analisis Status Mutu Air Secara Spasial di Sungai Babura

Abstract

The Babura River Watershed is part of the Deli River Watershed which covers the Deli Serdang Regency and Medan City with an area of 4921.88 ha. The upstream area is an agricultural area, in the middle and downstream there are industrial areas and open areas. As time goes by, this river becomes increasingly polluted, meaning the water quality in this river decreases. In an effort to determine the quality status of water quality in this river, it can be assessed using the pollution index method, the CCME method and the NSF-WQI method. The aim of this research is to determine the spatial status of water quality in the Babura River. This research uses descriptive quantitative where the author will explain and conclude data in the form of numbers. The method used in determining research stations is purposive sampling, namely by selecting 15 research points based on the Babura river flow. Physical chemical and biological water parameters were also measured in the form of temperature, brightness, depth, current speed, TSS, turbidity, pH, DO, nitrate, phosphate, BOD and total coliform. The results of the research show that based on the physical, chemical and biological characteristics of the babura subgai it is still within normal limits for the life of aquatic biota, except for the phosphate parameters which exceed the quality standards. If based on the Pollution Index method the pollution status is light, according to the NSF-WQI method the pollution status is poor - moderate and according to the CCME method the pollution status is poor - fair.
