Abstract

Open mining activities result in decreased microbial biomass and negatively impact soil fertility. Soil microbes play a key role in the decomposition of soil organic matter and in nutrient cycling through mineralization mediated by the enzymes they produce. The purpose of this study was to analyze soil fertility levels at PT Bukit Asam’s various reclaimed land sites in Muara Enim Regency, South Sumatra, Indonesia, as determined by microbial populations and soil enzyme activity. The research was conducted using an explorative method across PT Bukit Asam’s reclaimed land sites. Soil samples from seven reclamation areas of different ages were analyzed. Our results showed that soil conditions and enzyme activity vary with reclamation age. At KTU, a 12-year-old reclaimed site, urease enzyme activity was 68.83 mg NH₄⁺·g⁻¹ dm·h⁻¹, with a microbial population of 82.64 × 10⁴ CFU·g⁻¹ soil. The highest phosphatase activity, 95.66 mg pNP·g⁻¹ dm·h⁻¹, was observed at the 9-year-old SP702 reclaimed site, with a soil pH of 5.23. Cellulase activity at the 21-year-old Udongan site was 21.51 mg GE·g⁻¹ dm·h⁻¹, with a cellulolytic microbial population of 1.9 × 10⁴ CFU·g⁻¹ soil, higher than at other reclamation sites. Invertase activity at the 15-year-old Tupak site was 24.37 mg GE·g⁻¹ dm·h⁻¹. Soil enzyme activity can serve as an indicator of soil quality and microbial activity, reflecting biochemical transformations in the soil and exhibiting high sensitivity to environmental changes.

Abstract

Abstract. Remote sensing is composed of many interrelated processes to be able to consider physical objects such as buildings, land, and plants which are objects that can be discussed by applications discussed in various disciplines that discuss geology, forestry, soil science, and geography. The use of GIS and remote sensing for fire monitoring has been widely used. However, this study is the first study conducted in the TNBS area after the Berbak National Park (TNB) in Jambi to join the Sembilang National Park (TNS) in South Sumatra. Hotspot distribution in this study was obtained using Getis-Ord-Gi * statistics, hotspot data collected from 2000-2018 in the TNBS area. The results of the hotspot distribution during the 2000-2018 recorded by MODIS satellites with time acquisition and statistical analysis using Gi* show the results that the hotspots gathered (80% confidence level) outside the TNBS area, which is a mixed fields area. Further studies on causes of fire in terms of socio-economic and cultural needs to be done to get the right advice in reducing the risk of loss of forest cover and diversity in TNBS. Keywords: mitigation, hydrology, DAS
