This study evaluates the value added, operational cost dynamics, and ex-ante capital budgeting of full-wash Pagar Alam Robusta coffee enriched with a four percent crude catechin extract from gambier. Primary empirical processing parameters from field processing units were integrated into a enterprise simulation operating at 270 kilograms per cycle. Value-added transformation was determined using the Hayami method, while multi-year feasibility was evaluated over a five-year horizon discounted at four point seven five percent. Results show that the functional formulation yields a value-added margin of IDR 189,265 per kilogram, representing a value-added ratio of 52.57 percent. At full cycle capacity, the unit production cost of IDR 130,682 per kilogram and a cost-plus retail price of IDR 347,000 per kilogram generate an operational surplus of IDR 58,405,833 per batch. Discounted cash flow analyses indicate an ex-ante net present value of IDR 434,485,985.07, an internal rate of return of 51.80 percent, and a benefit-cost ratio of 1.031 against an initial outlay of IDR 250,650,000. Therefore, bio-fortifying Robusta coffee with natural catechins represents a financially feasible agro-industrial enterprise.
