Clove or Syzygium Aromaticum is one of Indonesia herbs and spices that have a variety of uses; its oil contained >80% eugenol and was reportedly able to act as anti-microbial, anti-fungal, and anti-inflammatory. Encapsulation was done to protect clove oil from oxidation. Eugenol encapsulation has been studied with casein micelle as its encapsulator. Production of encapsulated eugenol uses 8 unit procedure, with a spray dryer to form a solid product. The economic evaluation shows that the project capital investment is $1,249,000 with the annual operating cost of $1,448,000. Annual production capacity is 6972 kg/year, generating a revenue of $1,634,000 with product price $234.32/kg. Payback period estimated is 6.63 years with IRR 14.30% and NPV $334,000. Sensitivity analysis is conducted using three parameters of payback period, NPV and IRR show that product price fluctuation is the most sensitive variable, followed by capital investment and clove oil price.
