The consumption of lithium grows significantly on the global market, especially in Indonesia. To fulfill the demand, valuable lithium extraction from another natural source is considered, such as geothermal brine. During the research, the electrodialysis device was operated using different temperatures (30, 35, and 40 °C) and electric voltage (2 V, 3 V, and 4 V). The direct electric current was supplied by the electricity source, which comes from outside the membrane module. Due to the possible blockage on the membrane, synthetic geothermal brine was used in this study instead of nature-derived. Temperature and potential differences played essential roles in the concentration of lithium from the brine. The highest concentration is gained at temperature and electric voltage of 40 °C and 3 V, respectively.
