Abstract

Coal mining can disrupt the balance of the ecosystem, including the soil environment ecosystem as a habitat for soil arthropods. This study aims to determine the soil arthropod family, relative density, diversity, dominance and evenness of soil arthropods in the revegetation area of the ex-mining area of PT. Bara Alam Utama, knowing the relationship between environmental factors and soil arthropod diversity, knowing the soil arthropod family which has the potential as bioindicators and knowing the relationship between revegetation age and diversity of soil arthropods in the revegetation area of the ex-mining area of PT. Bara Alam Utama. The research was conducted in the revegetation area of the former coal mine area of PT. Bara Alam Utama in Lahat district, South Sumatra. The research area consists of 8 location points which are differentiated by revegetation age including natural areas, revegetation areas with age 7,6,5,4,3,2 and 1 year. The research was conducted using the exploratory survey method, the determination of the sampling location was carried out based on the purposive sampling method, the sampling was carried out by a combination method, namely pulling 100 m transects with 5 sample plots inside measuring 20 x 10 m at each revegetation age. The results showed that the highest soil arthropod diversity index was at the 3 year old revegetation location (H = 0.915) and the highest soil arthropod evenness index was at the 3 year old revegetation location (e = 0.17), while the highest soil arthropod dominance index was at 5 year old revegetation location (D = 0.886) which causes the 5 year revegetation location to have the lowest soil arthropod diversity index and evenness index (H = 0.351 and e = 0.054), while the lowest soil arthropod dominance index value is at the 3 year old revegetation location (D = 0.667), so it can be seen that there is a correlation between the diversity index and the evenness index of soil arthropods where both are inversely proportional to the results of the calculation of the dominance index. The high and low diversity index at each research location is influenced by biotic and abiotic factors.
