Banana fiber is one of natural fiber and can be produced from pseudo stem with mechanical and chemical treating mechanism. The aim of this paper is producing regenerated cellulosic fiber from banana pseudo stem by using copper amine solution. Banana pseudo stem was collected around Jima zone and the fiber was extracted mechanically. The pseudo stem has around 6.5 w% of fiber and the fiber has a moisture content of 59.3 w% and has a cellulose content of 57-64 %. The analysis was taken which used to know the properties of raw fiber, mercerized fiber and regenerated fiber. Water absorption capacity is one useful technique to determine hydrophilicity of fiber. The water absorption of raw fiber, mercerized fiber and regenerated fiber was 4.85, 3.8 and 1.1 respectively. And the result shows that hydrophilicity of fiber decreases probably because of the hydroxyl group is replaced by sodium ion for mercerization and amine group for regenerated fiber. Other characterization techniques were also proceeded; such that FTIR analysis with a wave length between 4000 and 400 cm -1 , thermal stability of regenerated fiber from a temperature 25 2018 o C to 700 o C with a great mass loss from 200 to 400 o C. And also, the crystallinity of regenerated fiber was calculated by taking reference polymers and gives around 72% crystallinity. The optimum factors obtained from design are time of 60.23 hours, copper amine volume of 66.96ml and concentration for regenerating compound is 1.07M for responses of water absorption capacity is 1.09 and yield of 1.4 gram.
