This preliminary design of a magnesium chloride hexahydrate (MgCl₂·6H₂O) plant utilizes magnesium hydroxide (Mg(OH)₂) and hydrochloric acid (HCl) as the main raw materials. The selected production process is a neutralization reaction, with a production capacity of 30,000 tons per year and an operating period of 330 days annually. The plant is planned to be constructed in Meulirang Village, Bungah District, Gresik Regency, East Java, Indonesia, occupying a land area of 22,671 m². The proposed business entity is a Limited Liability Company (PT) employing 98 workers under a line-and-staff organizational structure. The water supply is obtained from the Bengawan Solo River, which has a flow rate of 199,768.415 kg/h, while the electricity demand is fulfilled by a generator with a power capacity of 6.49 MW. The results of economic analysis are below: 1. Fixed Capital Investment (FCI) = Rp 1,137,144,035,974.07 2. Working Capital Investment (WCI) = Rp 247,893,084,763.58 3. Total Capital Investment (TCI) = Rp 2,478,390,847,635.79 4. Total Production Cost (TPC) = Rp 1,746,849,500,782.95 5. Sales Revenue = Rp 2,192,757,248,765.88 6. Net Profit = Rp 334,430,810,987.20 7. Pay Out Time (POT) = 4 years 8. Break Even Point (BEP) = 43 % 9. Shut Down Point (SDP) = 35.45 % 10. Internal Rate of Return (IRR) = 15.50 %
