Abstract

This study examines customers' determinants of behavioral intention to utilize the PLN Mobile application using the Unified Theory of Acceptance and Use of Technology (UTAUT) with technological literacy as a moderating variable. The data were collected from 399 respondents in the UP3 Western Flores Area using purposive sampling and analyzed by Partial Least Squares Structural Equation Modeling (PLS-SEM). The model demonstrated adequate reliability and validity (AVE > 0.5; composite reliability > 0.7) with R² = 0.62 for behavioral intention. Results indicate that performance expectancy, perceived usefulness, social influence, and facilitating conditions significantly influence intention to use the app, β = 0.21–0.34, p < 0.05, while trust and hedonic motivation were not significant. Technological literacy cemented the relationship between intention and real use, emphasizing digital capability as a key adoption driver. Active usage is minimal amid high download rates. The findings provide theoretical contributions to digital service adoption models and practical implications for facilitating user support, literacy programs, and mobile utility system introduction.

Abstract

This study examines the determinants of users’ intention to adopt the PLN Mobile application among Generations X, Y, and Z in East Nusa Tenggara, Indonesia, by extending the Technology Acceptance Model (TAM) with additional constructs, including perceived value, perceived trust, perceived security, attractiveness of alternatives, and social influence, with generational cohort as a moderating variable. A quantitative causal design was applied, collecting data from 438 PLN customers using proportional stratified sampling across four regional offices. Data were analyzed using Structural Equation Modeling–Partial Least Squares (SEM-PLS). The results revealed that perceived ease of use (β = 0.322, p < 0.001), social influence (β = 0.268, p < 0.001), and perceived security (β = 0.194, p < 0.01) had significant positive effects on intention to use, while perceived value, perceived trust, and perceived usefulness were not significant predictors. Social influence also significantly influenced perceived trust (β = 0.531, p < 0.001). Moderation analysis indicated that Generation Y exhibited the strongest moderating effects across most relationships, whereas Generation Z had the least impact. These findings provide actionable insights for public digital service providers, emphasizing the need to enhance ease of use, strengthen security, and leverage peer influence to improve adoption across generational segments.
