Oil palm frond waste can be utilized as compost through fermentation process. This research aimed to study the ability of local bioactivatorsTrichoderma asperellum (LBKURCC1 and LBKURCC2) to degrade palm fronds with a series of pile reversing variation during composting. Composting process was started with chopping palm fronds in a size of ±5 cm, and those chopped palm fronds were arranged int…
