The Effect of White Rot Fungus (Ganoderma sp) as Decomposers on Composting Using Combination of Cattle Feces and Water Hyacinth (Eichhornia crassipes) as Organic Matter

In Indonesia, cattle feces (CF) and water hyacinth (WH) plants are abundant but have not been widely revealed. The use of microorganisms as decomposers in the fermentation process has applied, so researchers interested studying further. This study was to evaluate effect combination CF with WH on composting by applying white-rot fungal (WRF) (Ganoderma sp) microorganism a decomposer. A number six types treatment compared R1(ratio CF:WH)(25%:75%)+WRF; R2(ratio CF:WH)(50%:50%)+WRF; R3(ratio CF:WH)(75%:25%)+WRF; R4(ratio CF:WH)(25%:75%) without WRF; R5(ratio CF:WH)(50%:50%) R6(ratio WRF. results showed that WRF organic matter (CF WH) at different ratios affected properties compost such pH value, C-organic, N-organic, C/N ratio, P2O5 K2O compounds. decomposer significantly decreases increases value K2O. produced accordance standards set Indonesian National Standard (INS) regulation Ministry Agriculture Republic Indonesia. needed consider producing compost. Based study, it concluded R1(CF: WH)(25%:75%)+WRF) best ratio produce using properties.
