Environmental management effort of ex-coal mining pit (void) in the new capital city of Indonesia (IKN).

In Indonesia, most coal mining systems are carried out using the open pit mining method. This method is considered cheaper and easier to apply in the field but has an impact on the creation of ex-coal mining pits (void). Recent regulation states that every mining company is obliged to carry out reclamation including environment management efforts for mining pits. However, not all mining business actors have complied with this effort, especially companies that do not have official permits. This ex-coal mining pit existence in the new capital city of Indonesia (IKN) delineation area become a crucial issue to be managed appropriately and wisely. The IKN Nusantara is the future capital city of Indonesia designed as a smart forest city, where 75% of the total area is maintained as a green space. This paper describes the management effort than can be carried out in ex-coal mining pit (void) within new capital city (IKN) Nusantara. All of the environmental management efforts for ex-coal mining pit (void) need to be aligned with detailed urban spatial plans in the future. There are several alternative efforts to utilize void that can be carried out, for example, as a source of clean water and raw materials, tourist destinations, sports areas, wildlife wetland habitats that are connected to the surrounding forest, landfills, agricultural reservoirs, and also water sources for forest fire mitigation.
