In the era of the Covid-19 pandemic, Badung Dukcapil Department developed several innovations in digital-based population administration services, namely the Badung Aku Sapa service and the 3 in 1 ( three in one ) service. The objectives of this research are: 1) To determine the effectiveness of the 3 in 1 Badung Aku Sapa service program in Sulangai Village, Badung. 2) To determine the supporting and inhibiting factors for the effectiveness of the 3 in 1 Badung Aku Sapa service program in Sulangai Village, Badung. The research results show that: 1) People can take care of making population documents themselves and is very time efficient. 2) People can now take care of making their population documents online. However, the community still handed over the preparation of population documents to the kelian at their respective department offices. 3) Socialization of the 3 in 1 Badung Aku Sapa service program by the Badung Regency Population and Civil Registry Service to the Sulangai Village government and all kelians in Sulangai Village has been carried out. However, the public still does not fully understand the socialization of the 3 in 1 Badung Aku Sapa service program. Many people cannot apply for population documents because some people do not know how to use the application and cannot operate a computer.
