ABSTRACT This NPK Fertilizer plant design uses raw materials of Sulfuric Acid, Phosphoric Acid, Ammonia, KCl and Urea. The production process used is Mixed Acid Route. The plant is planned to operate for 330 days per year continuously for 24 hours per day, with a production capacity of 330,000 tons per year. The planned form of the company is a Limited Liability Company (PT) using the line and staff structure method. Labor requirements to run this company amounted to 139 people. The location of the plant is planned to be established in Sungonlegowo area, Bungah District, Gresik Regency, East Java with a land area of 55,000 m2. The water source of this factory comes from the Bengawan Solo River, East Java with a total water demand of 249,700.55 kg/hour. The source of electricity is obtained from PLN with a power of 2.931 MW. The results of the economic analysis obtained are as follows: 1. Fixed Capital Investment (FCI) = Rp 1.106.531.214.519,15 2. Working Capital Investment (WCI) = Rp 681.519.519.992,61 3. Total Capital Investment (TCI) = Rp 4.042.256.587.887,14 4. Total Production Cost (TPC) = Rp 3.095.694.537.731,98 5. Sales Cost (SC) = Rp 5.738.406.672.375,72 6. Net Profit = Rp 1.982.034.100.982,81 7. Pay Out Time (POT) = 2.88 Years 8. Break Event Point (BEP) = 28.32% 9. Internal Rate of Return (IRR)= 42.34% 10. Rate of Return (ROR) = 49.03% Based on the technical and economic feasibility studies explained above, it can be concluded that the design of this NPK Fertilizer plant is feasible to proceed to the construction stage.
