Indonesia is one of the largest CPO palm oil producing countries in the world. However, with the increase in land used for oil palm cultivation and CPO production, there will be a lot of biomass waste generated during palm oil production to become CPO, one of which is the Empty Palm Oil Bunches (EFB). From the large amount of EFB produced by CPO to date, the level of utilization is still not optimal. From this question, it was found that there is a potential to study OPEFB fiber to increase the economic value of palm oil waste, one of which is as a composite filler. This research was conducted to determine the tensile and impact strength by producing an average value for the tensile test of 20.21 MPa, with a strain test of 0.0425, for the elastic modulus of 738.40 while the yield strength and total deformation, 6.41 MPa and 2.13mm. For impact testing, the average impact value is 0.1653 J/mm2. The results obtained from the test are for the Finite Element. From the simulation results of the TKKS electric car bumper using the Finite Element simulation, the results of the maximum von misses stress analysis have a value of 4.451 MPa for a frontal crash and 48.17 MPa for a side impact. In the front crash, it has been effective to withstand the working force, especially the crashing force. In the simulation for front crash safety factor is 3.327 and for side impact is 0.372. Deformation on the front crash bumper of 8,311 mm and 313.7 mm for side crashes. For the deformation that occurs in a frontal crash is elastic deformation and for a side impact it is deformed.
