Pra Rancangan Pabrik Pembuatan Surfaktan Sodium Lignosulfonat dari Sekam Padi dengan Kapasitas Produksi 30.000 Ton/Tahun (Tugas Khusus Rancangan Keteknikan Reaktor Sulfonasi)

Abstract

Surfactant Sodium lignosulfonate is a type of anionic surfactant which has water soluble properties. Sodium lignosulfonate is widely used in various industries such as dispersing agents in particle dispersion systems (gypsum paste and cement paste). The production process used in the design of the sodium lignosulfonate surfactant plant from rice husk is a delignification process with NaOH and a sulfonation process with NaHSO3 with a NaOH catalyst.. Preliminary plant design production of surfactant sodium lignosulfonate from rice husk with a production capacity of 30,000 tons/year will be established in Tagor Baru, Galang District, Deli Serdang Regency, North Sumatra with a total factory area of 20,095 m2. The raw material in the form of rice husk is obtained from a rice factory located in the Deli Serdang area around. The factory is designed to operate for 330 days a year. The planned company organization form is a Limited Liability Company (PT) with a line and staff organizational structure, and a total of 180 employees. The results of the economic analysis on this factory design are as follows: 1. Capital Invesment (CI) = Rp 849.556.485.502,- 2. Total Cost (TC) = Rp 750.971.873.409,- 3. Profit Margin (PM) = 32,18% 4. Break Even Point (BEP) = 26,34% 5. Return on Investment (ROI) = 29,68% 6. Return On Network (RON) = 49,47% 7. Pay Out Time (POT) = 3 year 4 month 8. Internal Rate of Return (IRR) = 37,85% Based on the results of the economic analysis, it can be concluded that this Plant for the manufacture of surfactant sodium lignosulfonate surfactant from rice husk is feasible to establish.
