Analysis of Water Quality Status Based on The Storet in The Lower River Ulu, Muntok District, West Bangka Regency

Abstract

The Ulu River is one of the rivers in the Bangka Belitung Islands Province, located in the Tanjung Village area, Muntok District, West Bangka Regency. The Ulu River has Murky and brown waters due to the influence of human activities such as household waste disposal. Therefore, this research aims to analyze the water quality Status of the Ulu Muntok River. The research was conducted in March And April 2024. The sampling method use purposive sampling in the Ulu Muntok River 2 times. Sample processing was analyzed at the Fisheries Laboratory for Aquatic Resources Management and the Biology Laboratory at Bangka Belitung University as well as at the UPTD Environmental Laboratory DLHK Bangka Belitung Islands Province. Analysis of water quality status is calculated using the STORET method. The results obtained for physical, chemical and biological parameters using the storet method, namely temperature, pH, Nitrate, Total Phosphate, TSS, BOD, COD, and total coliform are still below the class III quality standard threshold according to the designation, while DO has exceeded the quality standard threshold water thus getting a score of -10 with lightly polluted status. The results obtained at station I and station II were the same with a score of -10. This shows that the water quality status of the Ulu Muntok River is lightly polluted and is intended to comply with class III water quality standards, this is indicated by murky waters and low water clarity
