Preparation of industrial salt from traditional salt has been performed. The purpose of this research was to study the effect of the traditional concentration to the formation of salt crystals and to the percent yield of the salt. Purification of traditional salt is carried out by recrystallization. In this study used traditional salt sold in Yogyakarta. Concentration of the traditional salt used in preparation of the industrial salt were varied 0.2; 0.3; 0.4; 0.5; and 0.6 g/mL. NaCl concentration is determined by argentometry titration using Volhard method. Impurity levels of Ca, Mg, Pb, Cu, and Na are analyzed by AAS. Crystallinity salt were studied by X-ray diffraction (XRD). The results showed that the higher concentration, the shorter the time needed for crystal formation. The highest yield of salt percentage 80.7% in found at a concentration of 0.3 g/mL. NaCl concentration is 98.87%. Salt recrystallization results does not meet the quality standards according to SNI 01- 4435-2000 salt for industrial salt. Pb concentration in the industrial salt does not meet the standard according to SNI. The industrial salt formed has a higher degree of crystallinity than traditional salt .
