This study aims to analyze the implementation of active electronic archiving (e-archive) innovation at the Investment and One-Stop Integrated Service Office (DPMPTSP) of Surabaya City using Everett M. Rogers’ Diffusion of Innovations Theory. A descriptive qualitative approach was employed, with data collected through observation and semi-structured interviews with employees directly involved in archive management. The analysis focuses on five innovation attributes: relative advantage, compatibility, complexity, trialability, and observability. The findings indicate that the e-archive system provides relative advantages in terms of cost efficiency, integration with the e-letter system, and ease of archive retrieval, although it has not significantly improved work efficiency. In terms of compatibility, the system aligns well with archival regulations, work processes, and employee capabilities. The complexity of the system is mainly related to technical constraints and limited user accounts rather than user competence. Trialability through initial training enables users to understand the system and reduces the risk of errors. Meanwhile, the observability of the e-archive benefits is more evident internally among employees than externally to the public. This study concludes that the e-archive has been reasonably well accepted as an internal innovation, yet further technical and managerial improvements are required to optimize its benefits.
