Prarancangan Pabrik Disproportionated Rosin dari Getah Pinus Merkusii melalui Reaksi Dehidrogenasi dengan Katalis Paladium Karbon Kapasitas Produksi 2.500 Ton/Tahun

Abstract

Disproportionated Rosin (DPR) is rosin that undergoes a catalytic reaction to remove conjugated double bonds, thus enhancing its stability. The primary goal of this factory design is to apply chemical engineering principles and provide initial information for designing a Disproportionated Rosin production plant. This pre-design for a Disproportionated Rosin plant utilizes Pinus merkusii gum through a dehydrogenation reaction with a palladium-carbon catalyst, with a production capacity of 2,500 tons per year. The main process in the pre-design consists of five stages: raw material preparation, raw material separation, reaction formation, product separation and purification, and raw material recycling. The plant is planned to be established in the Kendal Special Economic Zone, Kendal Regency, Central Java, covering an area of 6,900 m². A total of 195 workers will be required, and the business entity will be a Limited Liability Company (PT) managed by a director with a line-and-staff organizational structure. The required investment capital for the establishment and operation of the factory is IDR 298,872,825,337, with production costs amounting to IDR 254,749,017,737. Based on the feasibility analysis, the factory has a break-even point (BEP) of 40.78%, a return on investment (ROI) of 22.57%, a payback period (POT) of 4 years and 5 months, a return on net worth (RON) of 37.61%, and an internal rate of return (IRR) of 25.85%. From the economic analysis, it can be concluded that the pre-design for the Disproportionated Rosin plant from Pinus merkusii gum through the dehydrogenation reaction with a palladium-carbon catalyst is feasible for establishment.
