Abstract

The purpose of this research is to determine the tensile stress and interfacial shear stress of coconut fiber that has been treated Sodium Hydroxide and Potassium Permanganate. This research is divided into three stages: soaking for 3 hours, testing, and data analysis. Coconut fiber is soaked in a solution of 5%, 10%, 15%, and 20% sodium hydroxide solution. Then, soaking in a solution of Potassium Permanganate with concentrations of 0.25%, 0.50%, 0.75%, and 1.00%. After that, the coconut fiber is dried in the furnace at 90oC for 5 hours. Then, coconut fiber was tested for tensile stress and interfacial shear stress. Based on the results of the test can be concluded that the treatment of Sodium Hydroxide and Potassium Permanganate affect tensile strength, and the shear strength of coconut fiber. The largest tensile stress was obtained in the treatment of Sodium Hydroxide with a concentration of 20% ie 289.94 N/mm2, while the highest interfacial shear stress was obtained in the treatment also on Sodium Hydroxide with a concentration of 20% ie 3.09 N/mm2.
