One of the challenges faced by humanity is Global change phenomenon caused by mankind activities since the mid of 20th century. Global change resulting in global environmental change includes climate alterations; land productivity, oceans and water resources, atmospheric chemistry and ecological systems those could alter the earth life sustainability. The changes will impact on social or demographic, culture, food resilience, health, and poverty, water, and security issues. Makassar city-the gateway of national development in eastern part of Indonesia- and its surrounding areas got the impact. This nearby 0.22 km2 isle named Lae lae is one of several in Spermonde region, southern part of Sulawesi Island. Lae lae is located 1.25 km from Makassar and takes about 10 minutes by motorized boat. In 1997, the authority of Makassar city intended to put the island on commercialization. Investors might utilize it as recreational island by moving its resident to a new developed fishing village in the district of Biringkanaya, Makassar. The plan has failed due to resident reluctance. Initial observation of community activities in the Island found that in spare time during the day, gathering as the main activity usually carried out in various places. It involves infants, children, youths, elderly people, male and female, performing various activities such as sitting, sleeping, playing cards, gossiping, etc. There are three places are often used to gather, they are: ‘bale bale’ (place for sitting and sleeping), ‘lego lego’ (terrace on a stage house) and on the walkways. ‘Bale bale’ commonly located at siring (space under the stage house), terrace, courtyard, sidewalk, and along the beach. Not every house has ‘bale bale’ while ‘bale bale’ belongs to a family could be placed anywhere out of owners’ house, so neighbors and visitors may utilize it at anytime. Author is encouraged to conduct research by this trend on the study of ‘bale bale’ as an identity in a built environment to support social activities of community on the Lae lae island. Settlement pattern of Lae lae island is formed by the pattern of ring road and the linear pattern extended from southeast to southwest of the island. There are no specific spaces for gathering; it is encouraged residents to provide ‘bale bale’ for gathering purpose by utilizing useful material around. It is alleged that the space establishment on the ‘bale bale’ for gathering involves a fairly complex behaviors neither with regard on territories, space separation, or social levels. Research questions are raised: 1) what are the behavior settings on ‘bale bale’ as a gathering space in the populated island named Lae lae? 2) What are the factors those influence behavior such as gathering space settings? 3) What kind of territory formed on the ‘bale bale’? With a population of 400 heads of households within 1507 residents, research method will apply rationalistic paradigm with 3 stages methods. Firstly, positivistic methods through questionnaire surveys and quantitative inductive analysis through SPSS techniques; followed by a rationalistic methods through indepth interviews, qualitative inductive analysis using categorization techniques and interpretation; and finally, phenomenological method to explain the social phenomenon of community activities in Lae lae isle. Results are expected to construct contributed ideas, solving the problems of global change, particularly some solutions to guarantee the community sustainability of its social life along with the environment.
