Abstract

Trust in digital civil registration services depends on how citizens evaluate service information, interface usability, and the handling of personal information. This study examined the associations of perceived information quality, perceived ease of use, and perceived privacy protection with trust in Semarang’s Si D’nOK web portal. A quantitative cross-sectional survey was conducted within an April–October 2025 research period, with questionnaire collection from May to August 2025. Purposive sampling with equal district quotas yielded 200 adult users from Tembalang, Banyumanik, Pedurungan, and Semarang Barat. Participants completed 20 five-point Likert items. Construct means were analyzed using Pearson correlations and multiple linear regression with HC3 robust standard errors. Internal consistency coefficients ranged from .827 to .854. The model explained 27.6% of the variance in trust (adjusted R² = .265). Perceived ease of use showed the largest standardized association (B = 0.418, β = .398, 95% CI [0.275, 0.562], p < .001), followed by information quality (B = 0.232, β = .225, 95% CI [0.102, 0.361], p < .001). Privacy protection was positively correlated with trust but was not significant in the adjusted model (B = 0.061, β = .063, 95% CI [−0.061, 0.183], p = .324). Three sensitivity analyses preserved this pattern. The findings support evaluating navigation and service information as practical priorities while maintaining privacy safeguards. The nonprobability sample and cross-sectional design limit generalization and causal interpretation.
