Analysis of Water Quality of the Babakan and Ancar Rivers in the City of Mataram and Water Pollution Control Strategies

EasyChair Preprint no. 2531

Abstract

This study aims to analyze the water quality of the Ancar and Babakan rivers, and to formulate strategies for their control. The analyzed water quality is pH, DO (Dissolved oxygen), BOD (Biologycal Oxygen Demand), color, odor, and temperature. Samples were taken at 3 points in each river. The results of the analysis show that the Babakan and Ancar rivers are not suitable for use because they are turbid brown and turbid yellow. The smell of water is like the smell of dirt mixed with soil and the smell of mud. The results of Ancar river acidity measurements show that the pH value of water in normal conditions with an average of 6 (still within the limits of class II water quality standards) and in the Babakan river the average pH value is 8, still within the class II river water quality standards. This means that river water can still be used as a means of recreation, a place for raising freshwater fish, livestock, and agriculture. The measurement results of DO values ​​in the Babakan river were obtained 15 mg/l and in the Ancar river 32 mg/l. A large DO value indicates that the water has good quality. Measurement of BOD value in the Babakan river obtained 16 mg / l and in the Ancar river 3 mg / l. The water quality of the Ancar and Babakan rivers is physically polluted. Chemically, the quality of the Ancar river is categorized as mildly polluted and the river Babakan is categorized as moderately polluted, so that the control strategy can be carried out by reaeriasi.
