Abstract: This study was conducted to elucidate the functions of traditional ceremonies in fishermen’s communities in the District of Takalar (Takalar is a district in South Sulawesi provinci in lndonesia as the research location), South Sulawesi Province, Indonesia. Phenomenology method was applied in this study, including the following steps: location selection, respondent selection, data collection, data validation and data analysis. Results showed that in Takalar (Takalar is a district in South Sulawesi provinci in lndonesia as the research location) District, there are three cultural ceremonies usually conducted by local fishermen’s groups, namely: thanks giving ceremony for abundance fish catch (Cera’ Turungang) (Cara’Turungang is a thankgiving cereemony of fishers for the big result of catching fish), new ship inauguration ceremony (Icaru-carui) and blessing ceremony (Passili) (Passili is a blessing ceremony for the pregant in the 7th months). Those fishermen’s cultural ceremonies function not only as a vehicle to communicate with the metaphysic nature owning supra natural power but also as a tool to maintain harmonious and integrative relationship amongst the community members. Thus, they eventually believe that cultural ceremonies synergistically blend the transcendental belief (Islam Religion) and immanence belief (fishermen’s culture) to transform what is uncertain to be certain in their life, including their optimism of having abundant fish catch every time they are heading to the fishing field. To the fishermen, religion and culture (magic) have effective integrative power with strong values and norms, institutionalized in their communities through the processes of "Usages", "Folkways", "Mores" and "Custom".
