The imbalance between petroleum production and demand is one factor for the increased fuel price. EOR (Enhanced oil recovery) is an innovative method with substances designed to increase petroleum production. The chemical is a surfactant that can be made from biomass, namely rice (Oryza sativa). Rice is one of Indonesia's agricultural products, particularly in Majalengka, West Java. This research uses the lignocellulosic biomass produced in post- harvest rice husk as a raw material for synthesizing surfactants. Preliminary characterization of lignin used in this study showed a specific wave number of 1228.7 cm?1 as a ?-aryl ether bond and m/z 177 fragmentation as a coniferyl aldehyde molecule. The lignin content obtained was 71.78% with a 15% NaOH concentration. Sodium lignosulfonate (SLS) is produced from lignin sulfonation using sodium bisulfite (NaHSO3), which has a content of 54.29%. The results of the SLS characterization with a wave number in the fingerprint area, namely 613.4 cm?1 as a sulfonate group, had a high agreement with the NMR analysis results in the literature. Surfactant performance showed the formation of Winsor III microemulsions on decane oil with salinity and temperature variations. This shows that surfactant from rice husk has good potential as a chemical injection in EOR.
