Boric acid (H3BO3) have an important role in various industries, as an adjuvant in the pharmaceutical industry, glass industry, ceramic coatings industry, electronic industry and etc. Domestic demand remains to be imported from abroad. Boric acid factory in Indonesia can be establish because some reasons supported , that is domestic demand rising and local labor absorbsing. Boric acid plant capacity designed 10,000 tons/year. Making this boric acid by acidification process with mol ratio borax : sulphuric acid = 1:1.01 and by 100 °C temperature and 1 atm pressure operating condition. The reaction is Exothermic and irreversible type and running in continues stirred tank reactor (RATB). The Raw materials are 1,111.88 kg/hr borax (Na2B4O7.10H2O), 524.85 kg/hr sulphuric acid (H2SO4), and 96.75 kg/hr NaOH. Process support unit including water supply unit (process,cooling, boiler ,consumtion, and sanitation) from brantas river with 4,591.57 kg/hr water flow, steam supply unit as many as 25,186.37 kg/hr, air compressed supply unit as many as 60.48 m3/hr, electricity reserved unit as many as 300kW from generator and fuel supply unit as many as 384.76 L/hr. The number of employees for running this factory is 128 people. Boric acid factory with 10,000 capacity ton/year will be establish at 24,700 m2 area in Gresik , East Java The economic analysis result obtained that Total Capital Investment (TCI) of Rp. 387,717,108,140.64 and production total cost of Rp. 394,717,712,806.25 From appropriateness analysis result obtained that Return On Investment (ROI) before tax 31% and after tax 28,20%. Pay Out Time (POT) before tax 2,42 years and after tax 2,62 years. Break Even Point (BEP) of 46,85%, Shut Down Point (SDP) of 25,11%, Discounted Cash Flow (DCF) of 34,1%. This result can be concluded that the boric acid plant feasible to set up.
