Research output: Contribution to journalArticlepeer-review


As an archipelagic country, Indonesia has a concentrated deposit of salt in Java and Madura Island. Furthermore, the total demand for the mineral in 2017, 2018, and 2019 were 3.9, 4, and 4.2 million tons, respectively. This study was carried out in 4 stages, namely identification of raw materials, crystallization, mechanical, and re-crystallization. The salt crystallization and purification process is beneficial to the aquaculture, fishery, and health sectors. The results showed that the raw materials obtained from the coastal areas of East Java and Bali Island have an average NaCl interval estimation range of 80.31% to 92.37%, which indicates that they are suitable for salt production. The product obtained from the processes have the potential to initiate diversification of business development in the country with an estimation range of 95.38% to 97.25%.
