Abstract

Pulp from waste derived from corn husks is an alternative to wood which is very promising in overcoming forest destruction and global warming. With abundant and easy-to-obtain raw materials, corn husk pulp can become an economic commodity thereby increasing income and expanding employment opportunities. The resulting pulp product can be used as tissue paper, drawing paper with 75% brightness. So it can also be used as magazine paper too. In addition, the bleaching process uses laccase enzymes which are friendly to the environment and have no long-term impact. Pulp from corn husk and bleaching using laccase enzymes is produced with a capacity of 73,500 tons/year with 330 working days in 1 year. The factory location is planned in the Pulau Rakyat District area, Asahan Regency, North Sumatra Province, with an area of 33,560 m2, a workforce of 180 which requires 180 people, with the form of a Limited Liability Company (PT) business entity and with a line and staff organizational system. The results of the economic analysis of the Pulp Manufacturing Plant with Soda and Bleaching Processes Using Laccase Enzymes are as follows:  Investment Capital =Rp. 1,132,973,547,431  Total Cost =Rp. 1,837,237,553,745  Sales results =Rp. 2,205,000,000,000  Net profit =Rp. 227,399,310,562  Profit Margins = 15.845%  Break Even Point = 30.872%  Return on Investment = 20.071%  Pay Out Time = 4 Year 9 Months  Return Out Network = 33.451%  Internal Rate Of Return = 19.253% From the results of the economic analysis it can be concluded that the factory for Manufacturing Pulp from Corn Husks with Soda and Bleaching Processes Using Laccase Enzymes is feasible to establish.
