L Lignin as a raw material for the manufacture of Surfactant Sodium Lignosylfonate (SLS) is mostly contained in bagasse which is a waste from processing the sugar industry. This potential can provide an alternative for waste treatment as well as an alternative source of raw materials for making surfactants for EOR activities. The method of making SLS begins with the isolation of lignin, then proceeds with hydrolysis and sulfonation using Sodium Bisulfite (NaHSO3) at a certain temperature and pressure. Furthermore, the resulting SLS surfactant was tested for its ability to reduce the surface tension between water and oil, so that it is expected to be able to release oil from rock pores and be easily mobilized. The optimum level of reactants that produce the most lignin is the use of 100% NaOH from the weight of bagasse, Lignin is obtained 36.64% from the weight of the initial bagasse. Based on the Fourier transform infra red (FTIR) test, bagasse lignin and SLS sulfonated lignin have functional groups in accordance with standard functional groups. The results of 0.15% and 0.1% surfactant injection in the artificial core model showed an increase in RF values ​​of 4.7% and 14.7% in the temperature range from 30 - 50, but in the 50-80 temperature range, the RF value decreased again by 5% and 5.9%. while at the same room temperature (30C) with an increase in the concentration of SLS surfactant between 0.05% - 0.15%, it will increase the RF by 11% - 12%
