ABSTRACT The design of the ammonium nitrate plant uses nitric acid as raw material with ammonia. The overall production process uses a continuous process involving four stages of the process, namely the storage stage for raw materials, the preparation stage for raw materials, the reaction stage and the product purification stage. The production capacity of the Ammonium Nitrate plant is 165,000 tons per year with 330 working days per year. The form of business entity for this ammonium nitrate factory is a Limited Liability Company (PT) with a line and staff organizational structure with a workforce of 189 people. The location of the factory is planned to be established in the province of East Kalimantan. The raw material for nitric acid is obtained from PT. Kaltim Nitrate Indonesia, Bontang and ammonia from PT. Pupuk Kaltim, Bontang. The utilities required are 252,650 m3/hour water from the Bontang River water treatment, 9.027,201 m3/hour steam needs, and 376,992 kW electricity requirements obtained from PLN and the generator used if the electricity supply is from PLN. insufficient. The results of the economic analysis obtained are as follows: 1. Fixed Capital Investment (FCI) = Rp. 160.896.733.616,49 2. Working Capital Investment (WCI) = Rp. 17.877.414.846,28 = Rp. 178.774.148.462,77 = Rp. 1.827.671.136.781,79 = Rp. 1.986.707.550.862,57 = Rp. 107.210.055.539,34 = 4,7 tahun = 37,66% = 42,3% 3.Total Capital Investment (TCI)4.Total Production Cost (TPC)5.Product Sales (S)6.Net Profit7.Pay Out Time (POT)8.Break Even Point (BEP)9.Internal Rate of Return (IRR)10.Rate of Return (ROR)= 59,97%
