The preliminary design of dimethyl ether (DME) plant provided is using direct synthesis method with coal as a raw material. Coal is obtained from PT.Kaltim Prima Coal. The production capacity of this plant is 200.000 ton/year with work days of 330 days/year. The form of this company is Limited Liability Company (Ltd) and using structur of line and staff method, with total of manpower 227 people. The factory location was planned in Kariangau, West Balikpapan Regency, Balikpapan City, East Kalimantan with area of 63.135 m2. Water demand of this factory is supplied from Wain River in Balikpapan City with total water demand of 1.123.348,88 kg/hour, and electricity demand is fully supplied by diesel generator with power of 7 MW. From economic analysis was obtained: 1. Fixed Capital Investment (FCI) = Rp. 1.887.771.658.387,- 2. Working Capital Investment (WCI) = Rp. 209.752.406.487,- 3. Total Capital Investment (TCI) = Rp. 2.097.524.064.875,- 4. Total Production Cost (TPC) = Rp. 1.420.362.572.409, 5. Sales Cost (SC) = Rp. 1.947.094.649.661,- 6. Net profit = Rp. 395.049.057.939,- 7. Pay Out Time (POT) = 5 years 8. Rate of Return (ROR) = 18,83% 9. Break Event Point (BEP) = 38% 10. Net Present Value (NPV) = Rp. 76.230.127.260,-
