Prarancangan Pabrik Pembuatan Natrium Karboksimetil Selulosa (Na-CMC) dari Selulosa dan Natrium Monokloroaseat melalui Proses Buckeye dengan Kapasitas Produksi 4.800 Ton/Tahun

Abstract

Na-CMC is a high molecular weight compound resulting from cellulose modification. Na-CMC is widely used in various industries as a thickening agent, water binder, foaming agent, moisture-retaining agent, and coating agent. Na-CMC is most commonly used in the food industry. Currently, Indonesia's demand for Na-CMC is largely reliant on imports, while domestic consumption is increasing. Therefore, it is necessary to establish a Na-CMC plant to meet the domestic demand for Na-CMC. The preliminary design of the Na-CMC plant from cellulose and sodium monochloroacetate through the Buckeye process has a production capacity of 4,800 tons per year. The main processes in this plant design consist of three stages: raw material preparation, reaction stage, and Na-CMC purification stage. The plant is planned to be located in the Special Economic Zone (KEK) of Sei Mangkei, Kelapa Sawit Street, Subdistrict of Bosar Maligas, Simalungun Regency, North Sumatra, with a total land area of 15,551 m², 170 workers are needed, and the business entity will be in the form of a limited liability company (PT.), led by a chief director with a line and staff organizational structure. The establishment and operation of the plant will require an investment capital of IDR 1,040,398,035,212 and production costs of IDR 868,295,099,028, with sales revenue of IDR 936,000,000,000, resulting in a net profit of IDR 144,483,480,804. Based on the economic analysis, this plant has a Profit Margin (PM) of 22.043%, Break-Even Point (BEP) of 42.081%, Return on Investment (ROI) of 13.887%, Return on Network (RON) of 23.146%, Pay Out Time (POT) of 7.2 years (86 months), and an Internal Rate of Return (IRR) of 9.399%. Based on the results of economic analysis, it can be concluded that this plant is feasible to establish.
