Abstract

The purpose of this study is to assess water quality, specifically pH, conductivity, total dissolved solids (TDS), salinity, and turbidity. The research utilizes quantitative methods and covers 15 sampling points across the Timbalun River basin in Padang City, West Sumatra, Indonesia. Samples were measured based on several parameters, with three repetitions for accuracy. The testing took place from August to September 2024. The results showed that some water quality parameters, such as pH and total dissolved solids, met the standards outlined by Ministry of Health Regulation No. 2 of 2023. However, other parameters, including salinity, conductivity, and turbidity, did not meet the specified thresholds. It is essential to implement treatment measures to ensure the water meets the required standards for its intended use.

Abstract

PT Bumi Bara Makmur Mandiri is a mining company engaged in coal mining, located in Hajran Village, Bathin XXIV District, Batang Hari Regency, Jambi Province. The company employs an open-pit mining method, which results in the formation of depressions that act as rainwater catchment areas, creating pools (sumps). To manage these sump areas effectively for mining activities, a mine dewatering drainage system is implemented. Over the past ten years, rainfall data indicates a catchment area of 246.02 hectares, with an estimated rainfall of 280.88 mm for a return period of ten years. The groundwater that accumulates in the pooling area has an inflow rate of 0.11 m/s, leading to a total water discharge entering PIT A of 39.12 m/second. Currently, there is one pump available with a power capacity of 10.83 kW to remove this water. Due to the significant water discharge, it is essential to design an economical open flow that can handle a flow rate of 2.96 m/s. Furthermore, a design for a holding pond is required, as the existing capacity is insufficient to accommodate the incoming water discharge, which hampers the sedimentation process. To address this, a redesigned settling pond with dimensions of 46 m x 36 m x 7 m and six compartments has been proposed. This solution will enhance the effectiveness of the mine drainage process
