Indonesia is one of the largest producers of crude palm oil in the world. However, with the increase in oil palm planting area and CPO production, a lot of waste biomass generated during the oil palm production process is converted into CPO, some natural fibers but in this study using oil palm empty fruit bunches. Still not the best from these problems, we found the potential to study oil palm empty fruit bunches to increase the value of waste in palm oil mills, one of which is as a reinforcing material for composite materials. This study was conducted to compare the effect of chemical treatment time on the ratio of fibers and powders with the best mechanical properties. The comparison used is a long effect of treatment KMnO4 (10 minutes) and the effect of variations in the composition of fibers and powders (40%: 60%, 50%: 50% and 60%: 40%) Furthermore, the test impact and test. bendingThe highest test results on the price impact were with a composition variation of 60%:40% treated with KMnO4 for 10 minutes, with a value of 0.1498 J/mm2, while for the lowest with a ratio of 40%: 60%, KMnOtreatment4 for 10 minutes with a value of 0.1343 J/mm2. Results of testing the highest price bending with variations of compositionis 60%: 40% treated with KMnO4 for 10 minutes, with a value of 51.2534 N / mm2, while the lowest in the ratio 40%: 60%, treatment KMnO4 for 10 minutes with a value of 45.0526 N/mm2.
