This research aims to analyse the impact of information technology on cultural preservation, with a case study of the role of gender in passing on local wisdom of indigenous communities in Outer Baduy. This research uses a qualitative approach through a case study method involving data collection techniques of indepth interviews with the Outer Baduy community, traditional leaders, Baduy content creators; observation, and documentation. The research results show that there is use of information technology through social media for personal needs, modern lifestyles, promotions and transactions for products and services of the Baduy community. Gender roles can be seen through the figure of Ambu in maintaining customs and passing down local Baduy wisdom in the form of "Pikukuh" which contains taboos, taboos or prohibitions. In the construction of Baduy society, women are highly respected and have an important role in preserving local wisdom so that there is balance in the use of information technology among the young generation of Outer Baduy. The implication of this research is that the use of information technology in the younger generation of Baduy outsiders has positive and negative impacts so that the role of Ambu is very important in maintaining and passing on Baduy ancestral traditions.
