Abstract
Large quantity and high-quality salt are demanded in Indonesia, yet the quality of salt produced by farmers is still low. Increasing salt quantity and quality is possibly done through the implementation of geoisolator technology. This study aimed to investigate factors affecting the decision of salt farmers to adopt geoisolator technology. The study was conducted at the salt production center in Madura Island. A survey on salt farmer was carried out during August-September 2018. A total of 190 respondents consisted of 131 salt farmers who adopted geoisolator technology and 59 traditional salt farmers were selected as a sample in this study. Factors affecting farmer decision to adopt geoisolator technology was analyzed using logit (logistic regression) model. The result of this study showed that the decision of salt farmer to adopt geoisolator technology was affected by the number of productive-age family members and the number of dependent family members, land area, farmer participation in the group, farmer participation in extension. Enhancement in the adoption of geoisolator technology needs synergy between extension agent and salt farmer group so that the mentoring process and knowledge transfer will be achieved.
Highlights
Salt is an important raw and auxiliary material in the chemical industry, around 60 percent of the world’s salt production is used in this industry (Sedivy, 2009)
This study was conducted on Madura Island. This location was selected through the method of purposive sampling since salt production areas are distributed over all regencies, namely Bangkalan, Sampang, Pamekasan, and Sumenep as they become salt production centers and contribute to 26.3 percent of national salt production
Salt farmers applying geoisolator technology had less salt farming business experience compared to traditional farmers
Summary
Salt is an important raw and auxiliary material in the chemical industry, around 60 percent of the world’s salt production is used in this industry (Sedivy, 2009). Along with its rapid industrial development, Indonesia consumes industrial salt of 82.28 percent of the total national salt requirement (Kemenperin, 2018). The import of industrial salt to meet salt demand is still performed. The salt import is conducted since industrial salt requires NaCl content of above 95 percent. Salt produced by salt farmer according to (Adi et al, 2006), only contained NaCl content of less than 80 percent. The general perception of salt derived from
