- This study aims to determine the effect of NaOH immersion fiber volume fraction and the percentage without immersion to determine the impact and tensile strength of composite pandanus leaf composites. The immersion treatment of the fiber using Sodium Hydroxide (NaOH) solution directly affects the structure of the fiber such as replacing the chemical content of the fiber and increasing the performance of natural fibers as a composite reinforcement. The concentration of NaOH solution is 25% with a volume fraction of fiber is 25%, 50% and 75% with the hand lay up method. In this study the base pandanus leaf fiber was soaked for 4 hours in NaOH solution. The making of impact composite materials using ASTM D265 has a length of 150 mm, width 25 mm, and height 20 mm. Tensile composite material using ASTM D638-84 M1 has a length of 200 mm, width 25 mm, and height 12 mm. The impact strength of the composite, tensile stress and strain of pandanus leaf base fibers are increased by increasing the concentration of NaOH solution. 12 specimens impact and pull 12 specimens. The average results of impact tests that have been carried out show the impact strength value without 75% fiber immersion is 0.00965 Joule / mm2. The average impact strength with 75% immersion is 0.0165 Joules / mm2. The average results of tensile tests that have been carried out show that tensile and strain stress values without 75% fiber immersion are 20.2827 MPa and 3.6298%. The value of tensile stress, strain with 75% immersion is 26.8387 MPa and 2.9253%.
