Application of Trichoderma sp in pineapple biomass composting

Background: Pineapple litter has great potential as an organic source and if it can be decomposed properly turn into fertilizer. biomass is difficult to decompose due high lignin cellulose content which slow down the decomposition process. Thus addition of auxiliary microbes such decomposer fungi thought increase rate decomposition. Aim: The aim this research determine effect Trichoderma sp. inoculum grown on rice substrate pineapple composting Method: This study was in a completely randomized design (CRD) method consisting 6 treatments with two stages testing, there are fungal productivity test application litter. spore density viability (CFU) values were calculated for that incubated 14 days level inoculum. given then subjected process seven weeks. compost analyzed at fourth seventh week parameters observed C-organic C/N ratio. Result: results showed 2.0 x107 spores / ml CFU value 10.6x108 cfu 100% viability. best had lowest ratio value, P3 obtained 12,5% P2 9,6 Conclusion: use media medium Fungi percentage age.
