Surfactants (surface active agents) are compounds that are ampipic (hydrophilic and hydrophobic in one molecule), so they can be applied as emulsifiers, emuliency, defoaming, detergency, and others. Surfactants from lignin can be an alternative to surfactants from petroleum (petroleum), which are non-renewable and cause environmental impacts because they are difficult to degrade. The research stage was the delignification of OPEFB with NaOH, which had concentrations of 10, 20, and 30%. Observations made were the yield of lignin, TSS (total solids), surfactant concentration of sodium lignosulfonate with a UV-Vis spectrophotometer, and pH. The surfactant results using the UV-Vis Spectrophotometer test showed a high and stable surfactant content at 10% NaOH concentration in 30 minutes, namely 2.480; 2,360; 2,679; and in 60 minutes, which is 2,768; 2,812; 2,878.
