Abstract

Peat soil with its unique physical and chemical character is host to various microbe and fauna. In the peat, the existence of microbe and macrofauna influenced by several environmental parameters. Therefore, in this study we would like to obtain the information about fungi and macrofauna in the post fire degraded peat swamp soil with emphasize on two points which are (i) abundance of soil fungi and soil macrofauna (ii) to describe the environmental parameters (e.g. understory and chemical properties) on the existence of fungi and macrofauna community. Soil dilution and pitfall trap were used to collect microbes and macrofauna in the targeted post-fire peat soil: Post-fire peatland /bareland (A), post-fire peat-land revegetated in December 2016 (B), post-fire peat-land revegetated in April 2016 (C), post-fire peat-land revegetated in December 2015 (D). Result showed that abundance of soil fungi obtained during this study is 4×105 to 11×105 cfu/ml. While the macrofauna abundance is 353-1038 ind/m2. Fungi and macrofauna community in peatland affected by understory cover which related with revegetation activity. There is a trend of increasing the abundance of microbes and macrofauna on the land along with the increase of the percentage of understory cover.

Abstract

Revegetation of coal mine reclamation areas contributes to environmental improvement by sequestering carbon through vegetation. This study aimed to estimate carbon stocks in reclaimed and post-mining areas of PT Adaro Indonesia using various vegetation indices to assess the areas' contribution to carbon sequestration and identify the most effective estimation method. Six vegetation indices—NDVI, RVI, SAVI, GNDVI, RDVI, and IPVI—were derived from drone-based multispectral imagery and combined with field sampling for enhanced accuracy. Carbon stock was calculated based on biomass, which correlates with tree size and other observable carbon pools. The results showed that, although the Tutupan site had lower vegetation diversity, it stored more carbon than the Paringin site. Among the indices tested, NDVI produced the most robust estimation model, demonstrating a high correlation and low standard error, indicating its strong predictive model for assessing carbon stocks in reclaimed mining lands.
