Abstract
Coconut coir is a solid waste coconuts that contain lignin to be used as raw material for various chemical industries. Lignin is taken by alkaline delignification stage and continued with the isolation of lignin using acidification. The process of alkaline delignification coco using NaOH solution with varying concentration of 15-35 % and processing time 60-150 min. Phase of lignin isolation using 20 % H2SO4 solution followed by a purification process. Analysis result of lignin using Klason method obtained the highest yields of 37.16 % by using 25 % NaOH and processing time of 120 min.
