Indonesia is a country with great potential for energy and mineral resources, including coal. Coal mine water is characterized by high levels of total suspended solids (TSS). This occurs when overburden excavation activities are carried out so that clay minerals are exposed. Rainwater in a certain volume contacts the minerals contained in the overburden and flows on the surface carrying solids and oxidation products. This study aims to determine the effect of current strength and detention time on electrocoagulation performance in removing total suspended solid levels. The electrocoagulation research configuration is using monopolar iron electrode pairs with a continuous operation method. This study used artificial waste with TSS levels of 3865 mg/L. The variations used in this study were current strength (2 A; 4 A; and 6 A) and detention time (15 minutes; 30 minutes; and 45 minutes). The results showed that the electrocoagulation process was able to remove TSS levels. The optimum condition for TSS removal in this study was achieved at a current strength of 4 A and a detention time of 30 minutes with a percentage of TSS removal of 98.64% from the initial TSS concentration of 3865 mg/L to 52,43 mg/L. The TSS level has met the quality standards of the East Kalimantan Provincial Regulation Number 02 of 2011 concerning Water Quality Management and Water Pollution Control in the TSS parameter.
