This study aimed to investigate a salt factory to analyze its technical and economic aspects to determine the precise parameters for improving the quality of food-grade salt. The primary process of this factory involves grinding, washing, draining, drying, and fortification, supported by equipment like brine management, conveyors, sieves, and packaging. The proposed salt plant, designed for a 3-ton daily output over 15 years, requires 30 months for construction and a 4-month startup. The total capital outlay is USD 1,921,000, with USD 310,000 for technology and equipment. Economic indicators, including a Net Present Value (NPV) of USD 7,862,000, an Internal Rate of Return (IRR) of 46.48%, payback in 1.56 years, and a Return on Investment (ROI) of 64.28%, demonstrate feasibility. Establishing a salt plant in Indonesia supports food-grade salt production, stabilizes solar salt prices and enhances the welfare of traditional salt farmers. Ultimately, the results of this study can provide valuable insights for evaluating the feasibility of establishing a food-grade salt production plant in Indonesia.</span></span></span></div> Food-grade salt,crude solar salt,salt processing,salt plant,techno-economic analysis 80 96 http://ijiepr.iust.ac.ir/browse.php?a_code=A-10-3024-2&slc_lang=en&sid=1 Makhfud Efendy makhfud.espi@trunojoyo.ac.id 1800319475328460012032 1800319475328460012032 Yes Department of Marine Science, Universitas Trunojoyo Madura, Bangkalan, East Java, 69162, Indonesia Nizar Amir nizar.amir@trunojoyo.ac.id 1800319475328460012033 1800319475328460012033 No Department of Mechanical Engineering, Universitas Trunojoyo Madura, Bangkalan, East Java, 69162, Indonesia Kritsana Namhaed kritsana.namhaed@toulouse-inp.fr 1800319475328460012034 1800319475328460012034 No Laboratoire de Génie Chimique, Université de Toulouse, CNRS, INPT, UPS, Toulouse, France Muhammad Yusuf Arya Ramadhan yra.ramadhan@gmail.com 1800319475328460012035 1800319475328460012035 No Chemical Engineering Department, Universitas Indonesia, Kampus UI Depok, Depok 16424, Indonesia Mochamad Yusuf Efendi Efendi.mochamadyusuf@gmail.com 1800319475328460012036 1800319475328460012036 No Research Center for Biomass Valorization, Faculty of Engineering, Universitas Indonesia, Kampus Baru UI, Depok, 16424, Indonesia Mohammed Kheireddin Aroua kheireddinea@sunway.edu.my 1800319475328460012037 1800319475328460012037 No Department of Engineering, Lancaster University, Lancaster, LA1 4YW, United Kingdom Misri Gozan mgozan@ui.ac.id 1800319475328460012038 1800319475328460012038 No Research Center for Biomass Valorization, Faculty of Engineering, Universitas Indonesia, Kampus Baru UI, Depok, 16424, Indonesia
