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 FDA hydrolysis measurements as an indicator of peat soil quality. In addition, measurements of the physicochemical characteristics of the soil and the total microbial population 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 physico-chemical 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 measurement of FDA hydrolysis activity was carried out in two ways of soil preparation, namely without soil dilution (A) and soil dilution (B). FDA hydrolysis activity without soil dilution (A) ranged from 37,15 to 91,17 μg fluorescein/g soil dry weight/hour. The hydrolysis activity of the FDA for soil dilution (B) ranged from 29,85 to 124,51 μg fluorescein/g soil dry weight/hour. Soil dilution FDA hydrolysis activity (B) gives more sensitive results than FDA hydrolysis without dilution of soil (A). Soil dilution FDA hydrolysis activity (B) indicated that FDA hydrolysis activity on converted land tended to be higher than secondary forest, whereas FDA hydrolysis activity without dilution (A) did not show consistent results. The total bacterial population ranged from 4,35 to 16,8 x105 CFU/g of soil. The total mushroom population ranged from 1,17-5,25 x 104 CFU/g of soil. The results showed that the conversion of peatlands had a significant effect on the physicochemical characteristics of the soil, the hydrolysis activity of the FDA, and the total microbial population. From the research results, it can be concluded that the hydrolysis activity of the FDA is quite effective as an indicator of the quality of peat soils.
