Pra Rancangan Pabrik Sorbitol dari Tepung Tapioka melalui Proses Hidrogenasi Katalitik dengan Kapasitas Produksi 20.000 Ton/Tahun

Abstract

Sorbitol is a sugar alcohol produced through a reduction process from glucose and a hydrogenation reaction at high temperature and pressure. Sorbitol is widely used in the chemical industry such as in the food, cosmetic, toothpaste, polymer and pharmaceutical industries, where it is usually used as a food sweetener and thickener. The pre-designed factory for making sorbitol from tapioca flour through a catalytic hydrogenation process has a production capacity of 20.000 tons/year and operates for 330 days/year. The main process in this factory design consists of three stages, namely the glucose formation stage, the catalytic hydrogenation reaction stage, and the sorbitol purification stage. In the pre-design of the factory for making sorbitol from tapioca flour, it involves two main reactions, namely the hydrolysis reaction of starch into glucose which takes place in the liquefaction and saccharification reactor and the catalytic hydrogenation reaction which takes place in the hydrogenation reactor. The pre-design location for the sorbitol factory from tapioca flour through a catalytic hydrogenation process is planned to be in Bumi Ratu Nuban District, Central Lampung Regency, Lampung Province with a building area of 13.050 m2. The planned form of business entity is a Limited Liability Company (PT) and the organizational form is line and staff with a workforce of 276 people. The results of the pre-design economic evaluation of the sorbitol plant are as follows: • Total Investment Capital = Rp. 846.025.329.750 • Total Production Cost = Rp. 393.899.234.413 • Total Sales Results = Rp. 807.521.604.314 • Total Net Profit = Rp. 288.142.980.636 • Profit Margin (PM) = 50,97% • Break Even Point (BEP) = 21,56% • Return on Invesment (ROI) = 34,06% • Pay Out Time (POT) = 3 tahun • Return on Network (RON) = 56,67% • Internal Rate of Return (IRR) = 44,97% From the results of the economic evaluation it can be concluded that the Sorbitol Factory from Tapioca Starch through the Catalytic Hydrogenation Process is feasible to be established.
