Abstract

This research aims to evaluate acid mine drainage (AMD) treatment methods in the PT Laskar Semesta Alam coal mining area. The open-pit mining system in this area poses serious environmental challenges, especially regarding water and soil pollution. This paper focuses on the use of the coagulation-flocculation method to reduce total suspended solids (TSS) levels in wastewater, as well as analyse the effectiveness of the chemical coagulant Ensiflock C100with a concentration of 25% and flocculant Greenhydro ST-20 with a concentration of 0.25%. The research results showed that the optimum dose of coagulant was3.75 ppm and flocculant was 2.50 ppm effective in reducing TSS concentrations to reach environmental quality standards. This research also recommends the use of additional technology in the form of baffles to increase the efficiency of water residence time in settling ponds, so that it can improve water quality before it is discharged into water bodies.
