| dc.description.abstract | Indonesia’s coastline is one of the longest in the world. That is why Indonesia has a great potential for salt production and can be one of the world’s salt producer. However, Indonesia is still relying on the imported salt, especially from Australia to accommodate the salt demand. Quality of the local salt has to be improved with some purification methods to get the standard quality of industrial salt because the process still using traditional method. In this research, salt purification process is done using the hydroextraction method, where the salt crystals are purified using the pure saturated salt solution in a batch reactor with different classification of salt K1, K2, K3. F:S is varied by 1:30; 1:35; 1:40; 1:45; and 1:50. The quality of the purified salt are determined based on analysis of the levels of Na+, Ca2+, and Mg2+. This method can reduce 74,36% Ca2+ and 91,07% Mg2+. | in_ID |
