EPSILON: Journal of Electrical Engineering and Information Technology

 (P-ISSN 1693-4989 E-ISSN 2745-5688) is an open access engineering journal that publish all research article/review/short communication related to progres of electrical engineering and information researchs. Focus of EPSILON are electrical engineering and information technology. Scope of EPSILON are Power Engineering, Telecommunication & Information engineering, and Control & Instrument Engineering. EPSILON is published by Departement of Electrical Engineering Universitas Jenderal Achmad Yani.

The six selected articles published in EPSILON: Journal of Electrical Engineering and Information Technology, Volume 24, Number 1 (2026), contain 18 author entries, based on the names listed in the journal's table of contents. The articles cover several areas of applied engineering, including smart healthcare systems, earthquake early warning systems, computer vision, Internet of Things (IoT) monitoring, microwave filter design, and vehicle emission measurement.

Regarding institutional affiliations, the authors are associated with four higher education institutions: Universitas Negeri Semarang, Universitas Jenderal Achmad Yani, Universitas Kristen Maranatha, and Universitas Nurtanio. Universitas Negeri Semarang is represented in the MediGuard medication reminder system and the IoT gateway monitoring study. Universitas Jenderal Achmad Yani is represented in the earthquake early warning system and vehicle emission measurement studies. Universitas Kristen Maranatha is listed for the Raspberry Pi-based sentry system, while Universitas Nurtanio is listed for the microstrip band-pass filter study. 

Geographically, the verified institutions represent two provinces: Central Java and West Java. Universitas Negeri Semarang is located in Central Java. Universitas Jenderal Achmad Yani, Universitas Kristen Maranatha, and Universitas Nurtanio are located in West Java. Consequently, West Java accounts for three of the four identified institutions, while Central Java accounts for one.
