Oil palm empty fruit bunches (TKKS), Treatment hydrogen peroxide (H2O2), Impact test, and Bending test.Abstract
Indonesia is included in one of the countries with the largest production of palm oil or CPO in the world where production continues to increase every year, with the increasing production of CPO will result in an increase in waste generated, from the solid waste produced, one of which is empty palm oil bunches(TKKS). Until now the level of utilization is still not optimal in reducing the buildup of waste from empty oil palm fruit bunches (TKKS), from this in this study the author wants to know the potential of fiber from empty palm oil bunches (TKKS) to increase the economic value of the CPO waste, one of which is as reinforcement/filler in composites. In this study using alkaline treatment (NaOH) for 1 hour followed by treatment with hydrogen peroxide (H2O2) for 2 hours and the ratio of fiber and powder composition 40%: 60%, 50%: 50%, and 60%:40%. which then carried out tests impact and bending to determine the effect of fiber and powder composition on the strength of the composite. The results of the test show that the price impact highest is the composition variation of 60%:40%, which is 0,1498 J/mm2, while the price is impact lowest found in the 40%:60% composition variation which is 0,1343 J/mm2. The Stress bending highest is found in the composition variation of 60%:40%, which is 66,3678 N/mm2, while the stress is bending lowest found in the 40%:60% composition variation which is 62,7830 N/mm2.References
