Studi Pengaruh Aktivitas TPA Mencirim terhadap Kualitas Air Sungai Mencirim, Kecamatan Binjai Timur

Abstract

The Mencirim River, which is located in East Binjai District, is one of the water sources that the community uses for daily activities. The flow from the Mencirim River passes through the Mencirim Landfill with a distance of ± 50 m from the Mencirim Landfill which is thought to indicate pollution from leachate contamination originating from the Mencirim Landfill which causes a decrease in river water quality. The aim of this research is to analyze the quality of river water and leachate water (temperature, pH, DO, TSS, BOD and COD), and analyze the level of pollution in Mencirim River water. This research was carried out in 2 sessions, namely on June 27 2024 and July 18 2024. The method for determining river water quality used in this research is the Pollution Index method contained in the Decree of the Minister of Environment Number 115 of 2003 concerning Guidelines for Determining Water Quality Status. Based on the results of research that has been carried out, there are parameters such as BOD that exceed class 2 water quality standards in Government Regulation Number 22 of 2021 which are at downstream of the Mencirim River, and TSS parameters that exceed leachate water quality standards in the Minister of Environment Regulation Life and Forestry Republic of Indonesia No. 59 of 2016 concerning Leachate Quality Standards for Final Processing Place Businesses. Based on the results of calculations using the Pollution Index method, the quality status or level of water pollution ranges from 1.0 ≤ IP ≤ 5.0 and is classified as lightly polluted.
