| Abstract | Gracilaria sp. is a red algae group seaweed (Rhodophyceae) that is commonly used in wastewater treatment because of its ability to adsorb metals and is economical. Utilization of Gracilaria sp. as an adsorbent for copper (Cu) metal has been carried out but has a low efficiency. In this study, activation was carried out with sodium chloride (NaCl) at various concentrations of 0%, 5%, and 10%, accompanied by variations in pH in acidic (pH 6), neutral (pH 7), and alkaline (pH 8) conditions, as well as variations in mass. Activated charcoal of Gracilaria sp. is characterized by testing water content, ash content, and iodine adsorption. After characterization, activated charcoal of Glacilaria sp. was applied to electroplating industrial wastewater containing heavy metal Cu for 1 hour. The results showed that the use of 1 g of activated charcoal of Glacilaria sp. using 5% NaCl at pH 8 has the best efficiency of 96.70% for Cu adsorption. Based on the data, it can be concluded that the use of activated charcoal of Gracilaria sp. potential to be used in the electroplating wastewater treatment process. |
