PRARANCANGAN PABRIK EDIBLE RICE BRAN OIL DENGAN KAPASITAS 11.000 TON/TAHUN

Abstract

A Rice Bran Oil Refinery will be established in Karawang, West Java, with an estimated start of production in the year 2026. The selection of the factory location is based on raw material sources, transportation facilities, and utility availability. This decision is due to Karawang being the largest producer of rice bran in West Java. Additionally, its proximity to a port is advantageous for both product distribution and transportation. The rice bran oil refinery plant has a capacity of 11,000 tons per year, operating 24 hours a day for 330 working days a year.

The process of producing rice bran oil involves three main stages: Pre-treatment, Extraction, and Refining. The Pre-treatment stage involves a pellet cooker, which stabilizes the Free Fatty Acid (FFA) levels by deactivating the lipase enzyme present in rice bran. The subsequent step is the extraction process using a rotocell extractor, aiming to extract 20% of the oil content from rice bran. The first purification process is degumming, involving the addition of phosphoric acid in proportion to the feed. Following that is the bleaching process, involving the addition of 2% bleaching earth based on the feed. This is followed by filtration to separate bleaching earth and other impurities from the oil using Leaf Filter and Cartridge Filter. The process then moves on to deodorization using tray distillation, which eliminates odor and color while reducing FFA levels through vacuum processing. The deodorization stage yields distillate products known as RBOFAD, which can be processed into biodiesel, and bottom products known as RBO, ready for packaging.

From the economic analysis, an Internal Rate of Return (IRR) of 13.36% is obtained. This IRR indicates that the factory is viable to establish with a 6% interest rate (Bank Jabar) and a Pay Out Time of 4 years and 6 months. The analysis is based on discounted cash flow. The capital for establishing the factory is divided equally between self-funding and loan financing. The total capital required for setting up the factory is Rp 197,236,564,132, and the Break Even Point (BEP) is determined to be 43.67%. The Net Present Value (NPV) is calculated to be Rp 36,323,277,165. The IRR sensitivity analysis shows that an increase in sales value significantly impacts IRR, while an increase in raw material costs significantly reduces IRR. However, an increase in establishment costs has a less significant impact on IRR. Therefore, the establishment of this factory is deemed feasible.
