Abstract

Agriculture is one of the biggest economy sector of Indonesia, with total area used for agriculture reaches 8.19 million hectares. Usage of fertilizer in agriculture causes contamination in the environment, with one of the biggest contaminant takes form as excess phosphate. This happens because phosphate is one of the most intensely used fertilizer and also has the lowest absorption rate by plant. Excess phosphate can cause eutrophication on bigger body of water. One method to reduce this effect is by doing phytoremediation, with Spirodela sp. and Iris pseudacorus. This method able to reduce phosphate concentration from 29.625 mg/l to 0.2 mg/l. By applying biorefinery concept, plants biomass will be used; Spirodela sp. would be used to produce duckweed powder with yield of 20.8%, while Iris plant will be extracted its flavonoid content to produce flavonoid powder, with yield 20.9%. These byproducts add the economic value of the system, with GPM of 5.91. This shows that applying biorefinery concept to phytoremediation activity is profitable.

Keyphrases: Biorefinery, Phytoremediation, excess phosphate, value-added byproducts
