This study was carried out with the aim of revealing the basic reasons behind the Tanebar Evav community still maintaining their traditions and customs. The customs and traditions practiced by the Tanebar Evav people with various ritual ceremonies are believed to be a cultural tradition to protect their business from various disasters that will befall or are often termed (Ntal Ruan) or repel danger. Ritual ceremonies in the Tanebar Evav community tradition are considered a bridge of communication with the Creator. These rituals provide meaning as a unifying tool. The ritual illustrates the value of social integration that is highly upheld by the Tanebar Evav community. The reasons for the Tanebar Evav community to continue practicing these cultural traditions include: (a) the existence of a knowledge system that is passed down from generation to generation, (b) the use of regional languages ​​in every traditional ritual, (c) the existence of a livelihood system, which always refers to on the traditions and culture inherited from their ancestors which have been practiced from generation to generation as a form of respect for their ancestors; (d) the existence of a belief system, where the Tanebar Evav people consider beliefs and customs to be the root of life. So if someone does not obey it, he will experience suffering, misery and even death. Because they maintain their customs and culture, the Tanebar Evav community seems isolated, especially since they live on an island which is quite far from the Regency City. However, despite this remoteness, a strong awareness of togetherness was born which was supported by the strict adherence to customs by the people of Tanebar Evav.
