The person group consists of: (i) elements of village government, (ii) administrators of village community institutions; and (iii) community elements who are directly involved in the Kalomba traditional procession, including community leaders, religious leaders, traditional leaders, and residents who live outside the village, but still have kinship relations with the residents of Tanah Towa Village. Place group through observation by looking closely at the traditional Kalomba procession and specifically observing the Massolo tradition.

Data analysis was carried out through the Qualitative Data Analysis (QDA) Software Program, to assist during the data processing and analysis phases as well as writing research reports. The research results show that unequal exchange occurs because there is competition to give passolo more than what has been received before, especially passolo from close family because they want to get praise and increase their social status in society. Passolo which exceeds tens of millions of rupiah has psychological, social, economic and cultural implications. However, the Kalomba tradition remains sustainable because it is a traditional obligation, social solidarity and mutual help within the village community.
