Analisis Dampak Alih Fungsi Lahan Gambut Menjadi Hutan Tanaman Industri Acacia Crassicarpa Dan Restorasi Terhadap Biomassa Karbon Mikroba Dan Enzim Selulolitik

Giam Siak Kecil-Bukit Batu Biosphere Reserve (GSK-BB) is one of Riau's peatlands that has been utilized as Industrial Plantation Forest (HTI), so that it can cause changes in the quality of the physical, chemical and biological properties of the soil. Improvements in the quality of peat soils can be sought through restoration. This study aimed to analyze the impact of peatland conversion into industrial plantations of Acacia crassicarpa and restoration of Cmik biomass and cellulolytic enzyme activity. Soil samples were taken from five different locations in the GSK-BB Biosphere Reserve, including HTI aged 1, 2 and 3 years, restoration and secondary forest (control). Cosmic Biomass was measured using the Chloroform Fumigation Extraction method. Cellulase and β-glucosidase activity were measured colorimetrically. The total population of cellulolytic bacteria was calculated using the Total Plate Count method. The physical and chemical characteristics of the soil varied from each location with a range of 3.63-3.97 for soil pH, temperature 27-29ºC, volume weight 0.20-0.25 g / cm3, soil dry weight 0.17-0.28 / gr of soil, water content of 252.79-424.29% and soil porosity of 65.28-84.55%. Cmic biomass ranges from 81.01-484.17 μg C / g of soil. Cellulase activity ranged from 20.42-30,90 μg glucose / hour / g soil and β-glucosidase activity 22.89-28.66 μmol pNP / hour / g soil. The total population of cellulolytic bacteria ranged from 0.27x104-0.59x104 CFU / g soil. Conversion of peatland function in the Biosphere Reserve GSK-BB generally causes an increase in soil cellulase activity and total cellulolytic population, but decreases Cmic biomass and β-glucosidase activity.
