Abstract

Pre-design Aluminum Sulfate plant with a capacity of 130,000 tons /year is planned to be established in Duri, Riau Province, with a land area of14,050 m2. This factory is planned to operate within 330 days/year or 24 hours a day with a totalof 126 employees. Bauxite as much as 965.4215 kg/ hour andas much as acid sulfate 15,051.3692 kg/ hour. Take as raw materials the production process will operate at a temperature of ll(fC, pressure of 1 aim with a total conversion of 61%. Utilities need supply 59,795.1847 kg / hour of water, 2513.5861 kg / hour of steam, and electricity 1092.191OKwh. From the results of economic analysis Aluminum Factory Pre-Draft Sulfate obtainedfixed capital of Rp 52.9 billion, working capital of Rp 19 billion profit before tax of USD 37.7 billion, andprofit after tax USD22.6 billion, percent return on investment (ROI) before taxes 35.53% and 21.32% after tax, pay-out time (POT) before taxes 2.19 years and 3.19 years after the tax, break even point (BEP) of 41.61% and shut down point (SDP) of 20.25%. Based on economic calculations it can be concludedthataluminum sulfateplant wasfeasible to be set up.
