The Influence of Perceived Usefulness, Performance Expectancy, and Social Influence on Intention to Use the Digital Population Identity (IKD) Program Mediated by Social Media Usage

Abstract

This study analyzes how Perceived Usefulness (PU), Performance Expectancy (PE), and Social Influence (SI) affect intention to adopt Indonesia’s Digital Population Identity (IKD), with Social Media Usage (SMU) as a mediator. Surveying 133 Jabodetabek respondents and using SEM-PLS, results show PE and SI significantly increase SMU, while PU has a negative (insignificant) effect. SMU positively influences intention, confirming its mediating role—fully bridging SI and intention, but not PU or PE. PE and SI also directly boost intention, unlike PU. Findings highlight the need to emphasize IKD’s benefits, leverage social networks, and optimize social media for public outreach.
