Geomembrane-based salt production method to increase the quantity and quality of small-scale salt producer

An appropriate salt production methods must be implemented to increase salt production's quantity and quality. This paper was prepared to introduce and demonstrate a new method, namely a geomembrane-based salt production method, which can contribute directly to increasing the quantity and quality of people's salt production. This method can be applied quickly with simple equipment, so this method is easy to replicate in various salt production center areas. The results of statistical tests directly show that there is a fundamental difference between the quantity and quality of salt produced by salt farmers using conventional salt production methods and geomembrane-based salt production methods, where geomembrane-based salt production methods are capable of producing much higher quantities of salt production with better quality.•The geomembrane-based salt production method is easy to implement because it uses simple equipment and can be made independently by salt farmers.•Using a geomembrane in this method can prevent leaks in the salt crystallization pond and optimize heat from solar energy to optimize the quantity of salt production.•This method prevents direct contact of seawater with soil. The effect is that the quality of salt produced from geomembrane-based salt production methods is higher than conventional salt production methods.
