Jakarta, June 12, 2026 — Energy utilization and innovation have become increasingly prominent topics across the globe. Amid escalating geopolitical tensions and global uncertainties, energy security has emerged as one of humanity’s foremost concerns. As the threat of an energy crisis becomes more apparent, the transition toward sustainable energy sources is no longer an option but a necessity to ensure long term sustainability.

In response to the urgency of energy transformation, the Electrical Engineering Study Program of Universitas Dian Nusantara (UNDIRA) took concrete action by organizing a Community Service Program (PkM) alongside the signing of a cooperation agreement with SMKN 34 Jakarta on April 17, 2026.

The activity was met with great enthusiasm by 50 participants, all of whom were active students of SMKN 34 Jakarta. Beyond serving as a platform for research development and innovation in renewable energy, the community service program was specifically designed to enhance participants’ knowledge and literacy regarding the utilization of solar energy through solar tracker technology.

The Head of the Electrical Engineering Study Program at UNDIRA, Dr. Arie Pangesti Ajie, M.T., who attended the event alongside Dr. Erfiana Wahyuningsih, M.T., and several student representatives from the Electrical Engineering Study Program, expressed his appreciation to SMKN 34 Jakarta for its openness to collaboration in the implementation of this community service initiative. The participation of lecturers and students also reflected UNDIRA’s commitment to fulfilling the Tri Dharma of Higher Education, particularly in the area of community engagement and service.

The event officially commenced with remarks from the Principal of SMKN 34 Jakarta, who emphasized the importance of synergy between vocational schools and higher education institutions in strengthening students’ competencies in the field of green technology utilization.

During the main session, Dr. Arie Pangesti Ajie delivered a comprehensive presentation accompanied by a live demonstration of a Solar Tracker system. He emphasized that the adoption of IoT (Internet of Things) technologies has become indispensable amid the rapid implementation of automated control systems across various industrial sectors.

He further explained the strategic role of ESP32, a low cost and energy efficient System on Chip (SoC) microcontroller equipped with integrated Wi Fi and Bluetooth connectivity. As one of the key components in modern IoT development, ESP32 has become an industry standard for a wide range of IoT applications.

In addition to hardware technologies, participants were also introduced to supporting software ecosystems, including Blynk, an IoT based platform designed to build, manage, and remotely control hardware devices such as Arduino and Raspberry Pi through smartphone applications and web based dashboards.

Furthermore, Dr. Erfiana Wahyuningsih, M.T., assisted by several Electrical Engineering students, presented various practical benefits of solar tracker technology that distinguish it significantly from conventional fixed solar panels. Solar trackers are capable of optimizing the angle of sunlight capture throughout the day, resulting in higher electricity generation compared to stationary solar panel installations.

This improved efficiency directly contributes to reducing long term energy costs, expanding access to clean energy for communities, and decreasing dependence on increasingly constrained conventional electricity distribution systems. Solar tracker technology is considered to have substantial implementation potential across residential, industrial, and public infrastructure sectors.

Through this community service program, the Electrical Engineering Study Program of UNDIRA hopes to continue expanding renewable energy technology literacy among younger generations while inspiring vocational high school students to actively innovate in addressing future energy challenges.
