Production and Hydrochemical characteristics of brine and salt at salt production area in Pamekasan

The objectives of this study were to investigate the hydrochemical characteristics of local salts from three districts, namely Galis, Pademawu, Tlanakan district, and PT. Garam. In Pamekasan regency. Two analyzed samples were seawater and salt. Hydrochemical parameters and chemical compositions of the main elements for seawater and its salt were investigated. The parameters for water samples were water temperature, Be, ammonia (mg/L), SO4 (mg/L). The parameter for the salt sample was NaCl purity. The sample of traditional pond brine was provided that the water temperature was in the range of 37-53C, Be (19-27 Be), ammonia (0.0953-0.4781 mg/L), and SO4 (22.071,0-52.360,0 mg/L). For PT Garam sample the value of temperature (41.0-43.0C), Be (20-25 Be), ammonia (0.1843-0.2143 mg/L), and SO4 (22.071-39.152 mg/L). The lowest NaCl score was traditional ponds (85,58), while the measuring of NaCl for PT Garam was 89.48 and 86.29%.
