Abstract


Kemudi village is one of the villages located in Gresik Regency is inhabited by people who live in pond farmers, this is because the Kemudi village is located in the middle of the pond. With this locations, it was found the problems of scarcity and limited freshwater resources which are utilized as clean water. Well water with high salinity levels as a result of the high content of Cl as salt and visual appearance of water that was yellow and murky, it made the well water in Kemudi village exceeded the standard quality Minister of Health Regulation No.32, 2017. One alternative for processing brackish water into freshwater is using activated carbon adsorbent method which physically activate with 400oC in furnace for 30 minutes. This study aimed to determine the appropriate contact temperature (30oC, 40oC, and 50oC) in adsorption process with contact for 60 minutes using activated carbon particle size of 60 mesh. From this research, the color of water became <0.2 TCU with 0 NTU turbidity, removed organic substances up to 0.42 mg/L, a total Fe of 0.088 mg/L and decreased of 9.31% Cl ion content.
