Generally, salt is used for consumption and industrial purposes. One of the salt-producing areas in Indonesia is located in the province of East Java. East Java salt production contributes 50% of the total national salt production. Sampang, Probolingo, Tuban, and Gresik are the main contributors to the production of people's salt in East Java. The demand for consumption salt is supplied by salt production. The salt demand increases in the last few years. However, the increase in demand for salt is not balanced with the supply of salt production. This study aims to analysis projection model the supply and demand of consumption salt in Sampang, Probolinggo, Gresik, and Tuban Regencies. The results of system dynamic analysis shows the projection of raw material salt production (supply) in Sampang, Gresik, Probolinggo, and Tuban regencies increase of 8.16%, 6.98%, 4.09%, and 8.18% during the simulation period (2019-2030).
