Pabrik natrium hidroksida berbahan baku natrium karbonat dan kalsiumhidroksida ini direncanakan akan didirikan di Gresik, Jawa Timur, denganpertimbangan ketersediaan bahan baku, kelengkapan unit penunjang proses, sarana transportasi yang memadai, ketersediaan tenaga kerja, serta kondisi lingkungan yang strategis untuk kegiatan industri. Pabrik ini dirancang untukmemproduksi natrium hidroksida sebesar 45.000 ton/tahun dengan sistemkontinyu selama 24 jam/hari dan 330 hari/tahun. Bahan baku yang digunakanterdiri dari natrium karbonat sebanyak 68.694.285,4 kg/tahun dan kalsiumhidroksida sebanyak 48.021.584,16 kg/tahun. Proses produksi natriumhidroksidadilakukan secara kontinyu, sehingga aliran bahan baku maupun produk dinyatakndalam basis laju alit massa per satuan waktu. Untuk mendukung kelangsunganoperasi, utilitas yang disediakan meliputi unit pengadaan air, unit penyediaansteam, unit penyedia udara tekan, unit penyediaan listrik, serta unit pengolahanlimbah. Bentuk perusahaan adalah Perseroan Terbatas (PT) menggunakan struktur organisasi perusahaan line and staff dengan jumlah karyawan sebanyak 210 orang. Dari analisis ekonomi diperoleh: Fixed Capital Investment (FCI) = Rp. 1.097.912.917.902,56 Working Capital Investment (WCI) = Rp. 121.990.324.21 1,40 Total Capital Investment (TCI) = 1.219.903.242.113,95 Break Even Point (BEP) = 40% Shut Down Point (SDP) = 30% Pay Out Time (POT)a= 1,76 tahun Return on Investment before taxes (ROI)b= 53% Return on Invesment after taxes (RO)a = 42% Discounted Cash Flow (DCF) = 51% Mempertimbangkan paparan di atas, sudah selayaknya pendirian pabrik natriumhidroksida dikaji lebih lanjut, karena memiliki keuntungan yang tinggi dimasamendatang. Kata kunci : Natrium Hidroksida, Natrium Karbonat, Kalsium Hidroksida. This sodium hydroxide plant, utilizing sodium carbonate and calciumhydroxideas raw materials, is planned to be established in Gresik, East Java. The locationwas selected based on the availability of raw materials, the completeness of supporting process facilities, adequate transportation infrastructure, workforceavailability, and environmental conditions favorable for industrial activities. Theplant is designed to produce 45,000 tons of sodium hydroxide per year throughacontinuous process operating 24 hours per day and 330 days per year. The rawmaterials required consist of 68,694,285.4 kg/year of sodiumcarbonate and48,021,584.16 kg/year of calcium hydroxide. Sodium hydroxide productioniscarried out continuously; therefore, both raw material and product streams areexpressed on a mass flow rate basis per unit time. To support continuous operation, utility facilities include water supply units, steam generation units, compressedair supply units, power generation units, and wastewater treatment units. Thecompany is established as a Limited Liability Company (Perseroan Terbatas/PT) and adopts a line-and-staff organizational structure with a total workforce of 210employees. The economic analysis yields the following results: Fixed Capital Investment (FCI) = Rp 1,097,912,917,902.56 Working Capital Investment (WCI) = Rp 121,990,324,211.40 Total Capital Investment (TCI) = Rp 1,219,903,242,113.95 Break Even Point (BEP) = 40% Shut Down Point (SDP) = 30% Pay Out Time (POT) = 1.76 years Return on Investment before Taxes (ROI) = 53% Return on Investment after Taxes (ROI) = 42% Discounted Cash Flow (DCF) = 51% Based on the results above, the establishment of a sodiumhydroxide plant deserves further consideration, as it offers promising economic benefits andprofitability in the future. Keywords: Sodium Hydroxide, Sodium Carbonate, Calcium Hydroxide.
