Population services, especially Family Card (KK) services, which are fast and efficient, have increased as the population of Denpasar City increases in 2024 to 673. 270 thousand people. In simplifying the administrative process, the Denpasar City Population and Civil Registration Office develops digital-based service innovations through the Taring Dukcapil program. However, in its implementation, several obstacles were found such as technical problems with the device, lack of socialization, limited employee competence, and unclear information. This research aims to understand the effectiveness of Family Card issuance services through Taring Dukcapil. The research uses a qualitative descriptive method with data collection techniques through observation, in-depth interviews, and documentation. Informants were selected purposively, and the analysis used Duncan's theory of effectiveness in Steers with indicators of purpose, integration and adaptation. The results of the study show that the service of issuing Family Cards through Taring Dukcapil is considered quite effective in simplifying the administrative process. Indicators of goals and adaptation have been achieved well, but the integration aspect is still not optimal, especially in terms of socialization and the availability of infrastructure. It is recommended that the Agency increase socialization activities to the community as well as maintain digital systems regularly and provide online assistance services such as call centers with officers who are responsive to technical obstacles.
