   Rice Straw is one of the most important materials that has been used for pulp and

   paper production due to its abundance and cost-effectiveness. However, the pulping and

   papermaking characteristics of the mixture of rice straw and used paper have rarely been

   investigated. In this experiment, delignified rice straw was mixed with used paper in order to

   make recycle papers with acceptable properties. Soda pulping process was carried out to

   remove out of lignin. The delignification was designed to measure the effects in terms of

   sodium hydroxide concentration and temperature, on the cellulose and lignin content of rice

   straw, and its tensile strength and water absorption. The mass ratio of used paper and rice straw

   was varied and its physical properties was observed and compared to paper from natural rice

   straw. The delignification was conducted using NaOH concentrations (4-10% w/w) and

   temperatures (60-90 degree) for 1 hour. The ratio of rice straw to used paper was varied (1:1-1:9).

   An optimum condition was obtained from rice straw delignification at NaOH concentration of

   8% and temperature of 90°C. The results of the optimum condition obtained the highest

   amount of cellulose content and tensile strength while having the lowest amount of lignin

      content and water absorption
