Pra Rancangan Pabrik Pembuatan Asam Oksalat dari Tongkol Jagung Menggunakan Metode Peleburan Alkali dengan Kapasitas 1.425 Ton/Tahun

Abstract

Oxalic acid is the simplest saturated dicarboxylic acid which has various functions including as a rust remover, preservative, explosives and as a reagent in the manufacture of colors. Oxalic acid can be produced through several processes, including the process of smelting alkali from corn cob. The need for oxalic acid in Indonesia continues to increase and is still met through imports from other countries. To overcome this problem, it is necessary to establish an oxalic acid plant from corn cobs in Indonesia. The establishment of this plant is expected to meet the needs of oxalic acid in Indonesia. Pre-design of Oxalic Acid Plant from Corn Cob is planned to operate with a capacity of 1,425 tons/year with 330 working days a year. The planned form of business entity is a Limited Liability Company (PT) with a total workforce of 100 people. The results of the economic aspect analysis obtained are as follows:  Total Investment Capital = Rp. 190,278,405,422, -  Total Production Cost = Rp. 131,983,623,380,-  Sales Revenue = Rp. 227,484,928,611,-  Net Profit = Rp. 63,229,113,410.  Profit Margin = 39,67%  Break Event Point = 30,86%  Return on Invesment = 33,23%  Pay Out Time = 3 years  Return on Network = 55,4%  Internal Rate of Return = 59.66% Based on the results of the economic aspect analysis, it can be concluded that “Oxalic Acid Manufacturing Plant from Corn Cob” is feasible to establish.
