This study aims to describe the implications of socio-economic change caused by tourism development and to explore the relationship between society and tourism from a sociological perspective. By using a qualitative approach with a case study research design, this study analyses data that was obtained through observation, documentation, and interviews. The participants involved were the local community living in Keciput village, the Keciput village staff members, the Tanjung Kelayang Beach tourism manager, and the Belitung Regency tourism office staff members. The study found that the tourism development of Keciput village had caused changes in the social and economic life of the local communities. In terms of social life, the emergence of tourism development had caused interactions to decrease. Previously, when the interactions among the people were still very intense, the economy of the community was also on the rise. However, ever since the tourism development took place, it has changed the people’s type of livelihood: where previously they had worked as fishermen, they are now working as transport services fishermen. The economic value of tourist activities is also classified into a higher category because the yield from the marine sources is very dependent on the season.
