| Summary: | Spirulina sp. is the most common cyanobacteria commodity used in bioindustry for functional food, source of protein, bioactive compounds and biopigment. The global Spirulina sp. market is estimated to grow up to 68,025.2 tons per year in 2025. Spirulina sp. biomass production still facing several problems such as high cost of culture medium with less effective result, especially in developing countries. The medium was modified with commercial chemicals and fertilizers that locally available in Indonesia in order to reduce the production cost. This research aimed to study the biological, technical, and financial feasibility of Spirulina sp. biomass production using modified commercial medium. Based on biological feasibility study, the used of modified commercial medium (ZK1 and ZK2) give a similar result compared to standard medium, equal for growth rate and protein content (p>0.05). However, the result contains lower fat, carbohydrates, and biopigment. The biomass productivity of ZK1 medium is 0,140 g/l/day and ZK2 medium 0,144 g/l/day. The financial feasibility analysis suggested that the system is feasible starting from 1,2-1,5 kg biomass production in a month. The best result gained on production capacity of 5 kg biomass with ZK2 medium, with NPV value of Rp. 183.208.962, IRR of 73%, B/C ratio of 7,8, and payback period in 7 months. It can be concluded that modified commercial medium was biologically, technically, and financially feasible to be applied in industrial biomass production of Spirulina sp.
