Vol. 5 No. 3 (2026)

For the publication of this latest edition (Volume 5, Issue 3). This issue once again presents a series of research articles that comprehensively explore various innovations and practical solutions in the fields of systems engineering, information technology, and applied electronics. The main focus of this publication highlights how the integration of smart technology can be implemented to address real-world challenges in society and industry. Readers will be presented with the latest studies, ranging from the utilization of the Internet of Things (IoT) in home security systems with RFID authentication and ESP32-CAM image notification, the implementation of hybrid LoRa-WiFi communication for water level monitoring, to the design and development of an Arduino-based two-zone automatic fire detector and extinguisher. In addition to developments in the hardware and automation sectors, this issue also enriches insights through software innovations and advanced data analysis. There is an in-depth study on the design of a mobile-based e-recruitment application to optimize corporate data management, as well as a comparison of various machine learning algorithms in predicting job salaries based on age, experience, and education. Furthermore, this publication also presents research highly relevant to the local regional context, namely the application of multicriteria spatial analysis using the weighted overlay method to map disaster risk zoning in Bandar Lampung City.

We express our deepest appreciation to all the authors who have contributed and entrusted the dissemination of their research results to this journal. We also extend our gratitude to the editorial board and peer reviewers for their dedication and thoroughness in maintaining the quality standards of scientific publications. We hope that all the articles presented in this issue will provide useful references, spark constructive academic discussions, and inspire the development of further technological research for academics, researchers, and practitioners.
