- This study aims to obtain phenolic lignin derived compounds through the lignin degradationof oil palm empty fruit bunches (OPEFB) using TiO2 photocatalyst and its antifungal activity againstFusarium oxysporum. The lignin degradation of OPEFB begins with the extraction and isolationstage using the soxhletation method with the presence of sodium hydroxide as a catalyst. The success of this stage is indicated by Gas Chromatography (GC) measurement of4-vinylguaiacol and Fourier Transform Infra Red (FTIR) spectroscopy measurement that indicated the appearance of seven specific peak of lignin occurring at wave numbers 3421 cm,1596 cm-1, 1508 cm-1, 1462 cm-1, 1041 cm-1, and 875 cm. This result is supported by the appearanceof specific peaks of guaiacyl and syringyl groups at wave numbers 1328 cm-1.Based on the variation of the degradation time, the lignin degradation of OPEFB with a degradationtime of 15 min. showed optimum results in the production of lignin derived compounds. In addition,it also provides a strong inhibitory response to the growth ofFusarium oxysporum with a clearzone diameter 2.39 cm.-1-1, 2929 cm and 1220 cm-1-1
