Riau has the largest peat land in Sumatra, which is about 4.044 million ha. Peatlands have the potential as a carbon sink and unique habitat. But most of the peatlands of Riau has been transformed into a function of oil palm plantations, tree plantations, agricultural areas and settlements. It is expected to cause a decline in soil carbon reserves, decreased function of peatland ecosystems and disruption of soil microbial activity. This study aims to analyze the impact of peat land conversion to plantations sago against microbial activity through soil microbial biomass C, cellulolytic enzyme activity, the population of cellulolytic bacteria, cellulolytic enzyme activity and physico-chemical character. Soil samples were collected from seven locations in the Village Lukun Meranti District, forest conservation, sago forest 40 year, sago forests + rubber, sago forests 80 years, new sago forest planting, sago forests 20 years and 120 years. Wind dried soil samples were fumigated for 24 hours using CHCl3 then added K2SO4 and filtered, 4 ml of extract was added H2SO4, indicator solution, potassium and titration with ferrous ammonium. Physical-chemical character of the soil varies at each location, for a soil pH between 5.13-6.25, from 28.25-30.50 °C temperature, humidity from 58.75-86.25%, dry weight from 0.68-0,79%, 21-32% water content, porosity and heavy volume of 23.47-29.48% from 0.23-0.29 g/cm3. Microbial biomass carbon ranged from 56.91-156.30 μgC/g soil. The population of cellulolytic bacteria ranged 0,76.104-3,04.104 CFU/g soil. Cellulase activity ranged from 0.01-0.09 μg glucose/h/g soil and β-glucosidase activity PNP 0.241-0.729 μmol /h/g soil. The results obtained showed that the transformation of peatlands affect microbial biomass carbon, the total population of cellulolytic bacteria and cellulolytic activity of soil in the village Lukun Meranti district.
