THE ABILITY OF TRICHODERMA SP AND PLEUROTUS SP FOR THE DECOMPOSITION OF OIL PALM EMPTY BUNCHES

Abstract

The empty bunches of palm can-not directly decompose into compost because it is still in the form of complex elements, so it must be degraded first, and the process of degradation naturally takes a very long time, for which the fungus used to accelerate the process of degradation. The fungus has a ligninolytic ability, namely the ability to dissipate enzymes that can degrade lignin. Materials used in this study include empty fruit bunches (EFB), bran, and dolomite lime. The ingredients were evenly mixed and then inoculated with the fungus in four treatments, which were without mushroom fungus, Pleurotus sp, Tramella sp, and Trichoderma sp. This study shows several attributes related to the quality of compost such as temperature, pH, macronutrient and C: N ratio. The treatment of Trichoderma sponge inoculation gives the best quality compared to others. The C / N ratio after 8 weeks of decomposition is 22.09. It can be concluded that the Trichoderma spray inoculation treatment can be a potential biodecomposer for EFB.
