Based on data obtained from the Badan Pusat Statistik, the production of turmeric plants in 2021 was 184,825 tons and increased by 6.32% in 2022, reaching 196,499 tons. Turmeric has several components, one of which is curcumin, which can act as an anticancer, anti-inflammatory, antioxidant, and even anti-infective agent (Wilken, Veena, Wang, & Srivatsan, 2011). The designed curcumin plant has a capacity of 60 tons/year with a purity of 96%. The raw materials used are turmeric powder at 3512.88 tons/year, ethyl acetate solvent at 1774.1818 kg/hour, petroleum ether at 2319.7634 kg/hour, and isopropyl alcohol at 31.0580 kg/hour.
In general, the stages of producing curcumin powder are divided into several main stages. The initial stage is the extraction of turmeric powder with an initial curcumin content of 3.42% using ethyl acetate solvent. The curcuminoid extraction results still contain essential oils, which need to be separated by a defatting process using petroleum ether. Furthermore, the separation of curcumin compounds from demethoxy-curcumin and bisdemethoxy-curcumin is carried out by mixing the curcuminoid extract with isopropyl alcohol, forming curcumin solids which are then dried. The total percentage yield of curcumin obtained is 1.7%.
The curcumin production plant is planned to be established in the Wongsorejo Industrial Estate, precisely in Krajan II, Alasbulu, Wongsorejo District, Banyuwangi Regency, East Java, with a land area of 2 hectares. The plant is projected to start operations in 2031, with a total capital investment of $53,528,767.50 and total production costs reaching $34,397,470.42. The selling price of curcumin is set at $204,210 per ton. Given that this industrial application is still relatively new, this plant is classified as low risk. Return on Investment (ROI) before tax is recorded at 8.38% and after tax at 11.17%. The pre-tax payback period (POT) is estimated at 4.16 years and after tax at 4.71 years. The Discounted Cash Flow Rate of Return (DCFRR) is estimated at 20.67%, with a Break-even Point (BEP) of 67.51% and a Shutdown Point (SDP) of 22.55%. Based on these parameters, the curcumin plant is considered feasible to operate and is of interest for further research.
