Abstract: Due to the swift flow of foreign cultures, the culture of the local community must be protected to preserve their traditional practices. Cultural erosion can be caused by internal and external factors. One of the community cultures facing the threat of change is Dayak Desa community in Ensaid Panjang village, Sintang District, West Kalimantan, Indonesia. The Dayak Village people traditionally live in the longhouse. This study tries to describe or identify the weaknesses and constraints of the Dayak Desa community in preserve their culture by presenting examples of the Rumah Panjai (the longhouse) tradition which is increasingly abandoned. This study revealed that internal factors that cause the fading of the Dayak culture in Ensaid Panjang village start from the awareness of the Dayak Desa community that it is easier to live outside Rumah Panjai because it is free from collective rules that bind colony. Another aspect identified from the interview results was the villagers lack of understanding of regulations that favor the preservation of local culture. In addition, the explanation or socialization from the government has not fully understood by the community. Besides, komunitas Dayak Desa ini memiliki poor kemampuan untuk beradaptasi dengan teknologi serta menjalin kemitraan dengan para pihak.
