Indonesia has 23 tailing dams and this will continue to increase along with the growing needs and mining activities in Indonesia. In the process, mining activities create byproducts in the form of slurry (tailings) which are stored in a containment called a tailing dam. Over time, tailing dams not only store slurry materials, but also store tailings in relatively dry form, known as Dry Stack Tailing Facility (DSTF). Currently, DSTF are developing in Indonesia so they need to be further studied and examined. This paper takes a case study of the DSTF Sumatra-1 and Sumbawa-1 using primary and secondary data. The implementation of DSTF needs to be studied and researched further, particularly its applicability in the high seismic region and high rainfall rate of Indonesia. The authors will discuss the recent findings of major issues in DSTF development as opposed to the normal tailing dams in Indonesia.
