The multi-dimensional natural disaster that hit Sigi and Donggala districts, Palu city, on 28 September 2018, had an impact on various aspects, including the arrangement of the community settlement. The Kaili Rai ethnic settlement that was built and has grown naturally in Taripa Village, Sindue District, Donggala Regency was unavoidable from the impact of the natural disaster which prompted them to flee from their settlement to a relatively flat place in the coastal area of Sindue District. The objective of this study is to reveal the form of adaptation of the community as settlers at the foot of Mount Sidole, Taripa Village, from a sociocultural perspective and local environmental aspects, which has implications for the sustainability of the way and system of living in new locations without significant changes compared to the situation before the disaster hit them. Research on the existence and sustainability of the Kaili Rai living system was conducted with a qualitative approach to reveal sociocultural factors, combined with a quantitative approach in order to explore and reveal environmental aspects.The findings indicate that the way and system of living of the Kaili Ethnic in Taripa Village, Sindue District is very adaptive. Such adaptation is strongly influenced by cultural and social factors with positive implications for sustainable settlements.
