| dc.description.abstract | Giam Siak Kecil-Bukit Batu (GSK-BB) Biosphere Reserve is one of the areas in Riau Province which has the largest area of peatland. Most of the peatlands in Riau have been converted into plantations and industrial plantations (HTI). The conversion of land functions has an impact on changes in vegetation, decreases in the surface of the peat, and affects the quality of the peat soil. This study aimed to determine the effectiveness of fluorescein diacetate (FDA) hydrolysis measurement as an indicator of peat soil quality. In addition, measurements of the physico-chemical characteristics of the soil were also carried out. Peat soil samples were taken from secondary forest (HS), industrial forest plantations (HTI), oil palm plantations (KS), rubber gardens (KK), burnt land (LBT), and restoration land (LR) using a purposive sampling method. Soil physicochemical characters were calculated using standard methods with varying pH results between 3,22-4,22, soil temperature ranged from 27,0-30,25 ℃, soil volume weight ranged from 0,16 to 0,21 g/cm3, soil dry weight ranged from 0,18 to 0,24 g, and groundwater content ranged from 282,02- 442,42 %. The FDA hydrolysis activity ranged from 37,15 to 91,17 μg fluorescein/g soil dry weight/hour. Rubber plantation locations had the highest FDA hydrolysis activity and industrial plantations had the lowest hydrolysis activity. In general, land use change has an effect on changes in the physicochemical character of the soil and the hydrolysis activity of the FDA. From the research results, it can be concluded that the measurement of FDA hydrolysis activity is effective enough to be used as an indicator of the quality of peat soils. | en_US |
