Pra Rancangan Pabrik Pembuatan Nitroselulosa dari Selulosa Jerami Padi dengan Proses Nitration Mixed Acid Kapasitas 3.700 Ton/Tahun (Tugas Khusus: Rancangan Keteknikan Detail Reaktor Nitrasi)

Abstract

Rice straw is a solid waste produced by rice plants during rice harvesting. Rice straw has a high cellulose content, so it has the potential to be used as an economically valuable product such as nitrocellulose. Nitrocellulose is the main ingredient for making rocket fuel, namely propellant and also as a raw material for making plastics or varnishes. The product is made using a nitration reaction by mixing sulfuric acid and nitric acid with the help of water with or without stirring. Preliminary Plant Design Nitrocellulose from rice straw cellulose with nitration mixed acid process is planned to produce with a production capacity of 3700 tons/year and operate for 330 days a year. The location of the plant is planned in Tanjung Pura District, Langkat Regency, North Sumatra Province. The land area required for the establishment of the plant is 16,855 m2. The required workforce is 177 people with the form of a Limited Liability Company (PT) with a line and staff organization system. The results of the economic analysis of this Nitrocellulose Plant from Rice Straw Cellulose are as follows:  Total Investment Capital = Rp. 615,602,031,608.60  Total Production Cost = Rp. 476,144,748,289.18  Sales Revenue = Rp. 680,362,724,586.60  Net Profit = Rp. 139,928,531,740.03  Profit Margin = 29.4%  Break Even Point = 33.19%  Return on Investment = 22.73%  Pay Out Time = 4.40 Years  Return on Network = 37.88%  Internal Rate of Return = 18.87% Based on the results of the economic aspect analysis, it can be concluded that the "Nitrocellulose Plant from Rice Straw Cellulose" is feasible to establish.
