Pengaruh Abrasi Dan Sedimentasi Terhadap Populasi Mikroba Dan Respirasi Tanah Dilahan Gambut Pesisir

Bengkalis District, which is predominantly characterized by coastal peatlands, is affected by abrasion due to tidal influences. This study aims to analyze the post- abrasion impact on soil physicochemical properties, microbial populations, and soil respiration rates. Soil samples were taken from four different locations: shrubland (SM), peat clumps (BK), peat balls (BG), and coastal peat (SS). The results showed that soil pH ranged from 4.70 to 5.34, temperature from 29.54°C to 31.11°C, salinity from 0.09 to 17.83 dS/m, soil volume from 0.16 to 0.33 gr/cm³, soil moisture from 140.48% to 273.15%, organic carbon from 47.45% to 57.35%, total nitrogen from 0.60% to 0.65%, C/N ratio from 76.55 to 88.05, available phosphorus from 14.20 to 72.10 ppm, and Kexch and Mgexch ranging from
0.05 to 3.75 cmol/kg and 8.75 to 72.90 cmol/kg, respectively. Soil respiration rates with glucose supplementation ranged from 3437.50 to 4021.88 mg CO₂/g soil/hour, with the highest rate found in peat clumps and the lowest in coastal peat. Without glucose supplementation, respiration rates ranged from 1747.63 to 2316.88 mg CO₂/g soil/hour, with the highest in shrubland soil and the lowest in coastal peat. The highest microbial activity was found in shrubland soil, while the lowest was observed in coastal peat with high salinity. Bacterial populations ranged from 1.0 to 15.5 × 10⁵ CFU/g soil, and fungal populations ranged from 0.2 to 6.8 × 10⁴ CFU/g soil. Based on these results, it can be concluded that locations with low salinity, such as shrub soils, tend to have higher microbial populations compared to abrasion-affected locations such as sesai soils. This indicates that stable environmental conditions support optimal microbial populations and activities in coastal peatlands.
Key findings: Abrasion, microbial community function, peatland, soil respiration, microbial population.
