<p align="justify"> Fires on peatlands result in disruption of the ecosystems and communities within them. Succession will occur after a forest fire, including the soil arthropod community. Soil arthropods are a community that is sensitive to changes in environmental conditions and some may play a part in succession journey as an ecosystem engineer. This study aims to examine the impact of fires and succession of soil arthropods in Sinar Wajo Forest Village, Mendahara Ulu Subdistrict, East Tanjung Jabung Regency, Jambi Province based on soil arthropod community and environmental conditions that existed on post-fire 2015 land, post-fire 2017 land, and compared to non-burning secondary forests as reference areas. The method used is pitfall trap at each observation location with three sets of traps each and done repeatedly as much as 2 x 24 hours to maximize the catch obtained. In addition, data collection of environmental conditions in the form of microclimate and edaphic factors at each research location. In the results of the study there were soil arthropod samples of 685 individuals classified in 64 morfospesies of 35 families. It can be concluded that the intensity and timing of fire affect the structure of the arthropod community of soil include decreasing species richness, individual abundance, and composition changes. In addition, fire also causes changes in environmental conditions in the form of microclimate and edaphic factors. Succession in both post-fire peatlands is ongoing with the reinforcement of environmental conditions and arthropod soil communities, with the prediction that ecosystem recovery on post-fire 2017 land will require a shorter period of time than post-fire 2015 land caused by a shorter distance to sources of biodiversity and lower fire intensity. <p align="justify">
