Fiber were derived non-wood plant where is the demand for fiber raw material increasing from year to year. The objective of this study is to determine the potential of napier grass as alternative fibr for papermaking industry by chemical and physical properties. The chemical properties involved in this study (cellulose, hemicellulose and lignin) according to TAPPI test, Kurschner-Hoffener and Chlorite method. For physical characteristic were determined by TAPPI method. Result shows that Napier grass have high potential; high content of cellulose and lower lignin and good of mechanical properties.  Thus, it can be conclude that Napier grass shows a potential to substitute raw materials of wood in pulp and papermaking industry.
