Pra-rancangan Pabrik Pembuatan Pupuk ZA (Zwavelzuur Ammonium) dengan Menggunakan Proses Merseburg Kapasitas 100.000 Ton/Tahun

Abstract

ZA fertilizer contains NH4+ ions, which are essential for plant growth in Indonesia, a predominantly agricultural country. ZA fertilizer is also an inorganic herbicide that can kill weeds (invasive plants). This fertilizer contains less nitrogen, increasing the cost per applied nitrogen mass in agricultural operations, but provides the advantage of incorporating another key nutrient, sulfur. The proposed ZA (Zwavelzuur Ammonium) fertilizer manufacturing plant uses the Merseburg process with a capacity of 100,000 tons/year and operates 330 days a year. The plant is planned to be located on Jalan Tambak Osowilangun, Benowo District, Surabaya City, East Java, Indonesia. The proposed ZA fertilizer plant design utilizes the Merseburg process to apply chemical engineering knowledge, including mass balances, energy balances, equipment specifications, and operational requirements. The results of the economic evaluation of the ZA fertilizer manufacturing plant using the Merseburg process can be seen as follows: Total capital investment : Rp 4.766.052.231.365 Production cost : Rp 2.351.746.330.506 Sales revenue : Rp 3.946.613.763.501 Net profit : Rp 985.541.114.829 Profit margin : 37,340% Break even point : 54,717% Return on investment : 20,064% Pay out time : 4 Tahun 9 bulan Return on network : 33% Internal rate of return : 30,062% From the results of the economic aspect analysis, it can be concluded that the ZA fertilizer factory with a Merseburg process capacity of 100,000 tons/year is feasible to be established.
