Accumulation Oil Palm Empty Bunches (TKKS) cause environmental problems if not solved. TKKS has a high cellulose composition, so it can be used as nanocellulose which has a high use value. The process of making nanocellulose from TKKS through the isolation stage of α-cellulose with a delignification process using Sodium Hydroxide (NaOH) 17.5% (b / v) at 80oC, bleaching using Hydrogen Peroxide (H2O2) 10% (v / v), hydrolysis using sulfuric acid and drying using freeze drying at a heating temperature of 53oC for 7 hours. Cellulose yield produced from the isolation process of α-cellulose from TKKS was 20.8%. The results of this drying process will reduce the aggregation of particles in the nanocellulose produced, so that nanocellulose is produced at 160-298 nm
