Summary: | The pulp and paper making industry is looking for new main raw material based on its physical, chemical and morphological characteristics. Currently in this industry, bagasse is the most useful raw material in pulp and paper industry. The objective of this study is to determine its suitability for pulping. Acacia auriculiformis is a fast-growing tree normally found in Indonesia and Australia. Acacia auriculiformis leaf contains of cellulose, hemi-cellulose and lignin. The range of lignin content in Acacia auriculiformis is 19%-20%. The hemi-cellulose and lignin contents was removed by soda-pulping process using different concentrations as followed; 3%, 5%, 10%, 15% and 20%. In order to determine the optimum pulping conditions for Acacia auriculiformis craft paper, several tests were conducted such as apparent density, tear test, tensile strength test and moisture absorption. It was found that the Acacia auriculiformis fibre treated with 3% sodium hydroxide (NaOH) solutions gave good tear test of the paper. For apparent density test, the best concentration of NaOH used for treating Acacia auriculiformis pulping is at 15%. From the study, the optimum concentration of NaOH in treating Acacia auriculiformis fibre is at 5% for best result in tensile strength. Hence, from the overall tests, 5% concentration of NaOH is the optimum value. From the findings, Acacia auriculiformis fibre has a potential to be used in paper making and food packaging industry. |
