Lignin is the largest component in black liquor, it is about 46% of solids total and can be isolated by precipitation using acid and base method. The purpose of this study was to get the best NaOH concentration to produce lignin with yield, solids total content, metoxyle lignins content, weights equivalent of lignin in the black liquor by pulping formacell process from oil empty fruits bunches. This study was done with isolation lignin process in black liquor used by NaOH concentration were 5%, 10%, 15%, 20%, 25%, and 30% from volume black liquor and then precipitationed for 10 hours. The result of this research showed the isolation of lignin with NaOH concentration 30% get the pH 5,42%, yield of lignin was 5,67%, solids black liquor total was 65,11%, levels of metoxyle lignin 14,61%, and equivalent weights of lignin was 1787,23. The result of FT-IR identifications of isolates lignin in NaOH concentration 25 and 30% showed a pattern infiltration spektro IR that almost a part that have the same infiltration at the wave numbers that showed lignin had one of the rings lignin was guaiasil, it was building blocks of non wood lignin.
