Rumah Rakit Mapping and Substitution Potential of Pontoon EPS Foundation Technology in Palembang City, South Sumatera, Indonesia

Palembang as one of the old town is that passed by the big riverin Indonesia has a distinctive Musi river cultural character, that is RakitTraditional House (Rumah Rakit). Rumah Rakit is located on the banks ofthe Musi river that divides the city of Palembang.

The observation unit is Rumah Rakitlocation in Musi river area, Palembang. The research approach uses aqualitative approach. The analysis used is descriptive qualitative supportedby spatial data for mapping and comparative to subtitition potency floatingfoundation technology.
