Natural fibers such as palm midrib, hemp, banana and kenaf fibers can be good reinforcing materials for thermoset or thermoplast composites. Composites that use natural fiber reinforcement can be improved by adding pressing time in the formation process. The purpose of this study was to determine the effect of adding variations in holding time to the mechanical properties of the composite material of oil palm fiber - PP. Palm midrib fiber material is processed by a simple hot press method. The temperature used in the pressing process is 200ºC with an emphasis of 1.5 tons. The variation of holding time is 20 minutes, 25 minutes and 30 minutes. The mechanical properties that have been tested are impact and density tests. The highest toughness strength was obtained at holding time of 30 minutes with an average value of 10 Joules and the highest density value was also obtained at holding time of 30 minutes with a value of 1.321 g/cm³.} }
