Abstract
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

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.
