The Gotong Royong culture, which is the hallmark of the Bajo community, continues to experience changes due to interactions with mainland people. As a result, the cultural values of Gotong Royong have been abandoned. Efforts to restore local wisdom, such as the Gotong Royong culture, are urgently needed in this era. This research aims to innovate by reintroducing this culture, particularly in housing and housing development cooperation. The reapplication of local wisdom (Gotong Royong culture) in this study is intended to ensure that the characteristics and identities of the Bajo people remain the basis for building their social capital. The researcher used a qualitative descriptive method with inductive and deductive approaches, along with a Value Engineering approach. This research was conducted within the Bajo Tribe's location, situated in Kabalutan Village,

Indonesia has a variety of (ethnic) cultures spread throughout Indonesia, one of which is in Central Sulawesi (ToKaili). The evolutionary process that is the object of observation is in the ToKaili community, which focuses on seTeori sosiologis klasik menjadikan sosiologis sebagai teori dasar.

The evolution method does not just happen but has a long process to achieve the ideal form of housing and housing. This study aims to uncover what is behind the phenomenon of home / personal life in ToKaili from traditional architecture. his research uses a qualitative method with a phenomenological approach. This analysis found several development periods ranging from nomadic settlements to permanent settlements, and its development at that time the solution became an ideal settlement.

In Indonesia, there are many unique settlement patterns, which reflect the customs and wisdom of indigenous tribes. The "Kaili" tribe in Central Sulawesi (To Kaili) is one of the many tribes in Indonesia who have their own principles in shaping their homes and natural environment. Some principles that become a benchmark in his life are: 1) "Hintuvu" (regulating human-human relations), 2) "Katuvua" (human-natural relationship), 3) "Pehakovia" (guardian of humans and nature or spirit). The question of his research is: How does "Pehakovia" become the foundation of spirituality to build the house and environment of the Natural "To Kaili"? This study aims to observe the role of "Pehakovia" in relation to procedures for building houses and the natural environment of To Kaili from time to time. Phenomenology methods are used to answer questions and goals. The results revealed the role of "Pekahovia" in the "To Kaili" community, ranging from the uniqueness of the settlement to the lifestyle of the "Tokaili". Phenomenological methods are also used to measure the role of Pehakovia in planning and designing homes and the surrounding natural environment. The core role of "Pekahovia" in the life of "To Kaili" is to find a balance of life in the To Kaili community. The concept of macrocosm into the concept of a microcosm concept is reflected in the application of local wisdom strategies in the home and settlement. The process of Internalization cosmological concepts in the home and environment aims to create a sense of security and avoid the possibility of disaster. The harmonious relationship between humans and spiritual guardians ("Pehakovia") is manifested by various traditional ceremonies that fill the lives of the "To Kaili" Society; this process shows the balance has occurred in the home and the surrounding natural environment.

Indonesia has experienced multiple disasters induced by several active tectonic faults that cause earthquakes. Central Sulawesi, one of Indonesia's Province, has an active fault known as the Palu-Koro fault. This fault periodically causes disasters (i.e. earthquakes, tsunamis, liquefaction, and landslides). The co-occurrence of these four disasters is locally termed Nalodo. ToKaili – the native tribe that inhabited Central Sulawesi Province – has faced these hazards for generations and formulated local wisdom to minimise their impacts. This local wisdom is called Pengataa. Pengataa serves as a guideline for environmental management, such as determining the location of settlements in consideration of hazards and the environmental equilibrium. This study explores the customary spatial planning (Pengataa) of ToKaili in responding to natural disasters according to disaster records evidence, including the 2018 Palu disaster. This study uses a qualitative method and finds the role of Pengataa in organising ToKaili settlements to minimise the impact of disasters that are free from the effects of Nalodo. This study conveys that customary spatial planning of ToKaili is worthy of considering in the planning of residential areas, especially in relation to natural disasters.
