In the Internet of Things (IoT) era, long-distance wireless communication is made possible by electromagnetic (EM) waves. Simply put, EM waves are energy waves formed from the vibrations of electric and magnetic fields, allowing them to propagate through space and form the basis for various modern communication technologies.

One type of electromagnetic wave widely implemented in the IoT era is the radio wave (RW). As a type of EM wave, radio waves are often used due to their ability to propagate without a medium like air or water, and because their intensity (amplitude and frequency) can be easily modulated. Both EM and radio waves are frequently used in various devices today, from Wi-Fi to Bluetooth in headphones and earbuds.

This certainly offers convenience and practicality for users, especially Gen Z. However, without our realizing it, electromagnetic and radio waves can gradually affect our health. Therefore, when using devices, especially wireless ones, we need to have knowledge about Electromagnetic Safety.

Electromagnetic waves and their variants contain radiation, which is divided into two categories: ionizing and non-ionizing radiation. As we know, excessive exposure to high levels of radiation can cause cell damage in the body and disrupt metabolism and cell development.

Furthermore, some studies also mention that constant exposure to EM waves can interfere with psychological and hormonal functions, which regulate our stress levels and memory.

According to studies published by various scholars in the field of Electrical Engineering, a range of 10 mW/cm² is generally considered a relatively safe threshold. Additionally, the Specific Absorption Rate (SAR)—the rate at which the body absorbs radiation—is influenced by two factors: the health condition of each individual and the energy level (emission, heat, electricity) generated by the source device.

By understanding the potential impacts of electromagnetic waves, we can take several steps to minimize radiation exposure:

1. Reduce Gadget Exposure: Especially during periods of rest. Parts of the body, particularly the brain and eyes, require sufficient rest from the radiation exposure caused by EM waves.

2. Maintain a Safe Distance: Devices like smartphones and monitors can emit EM radiation waves; therefore, it is important to maintain a safe distance when using them daily.

3. Avoid EM Sources: Avoid residential areas and developments near signal transmission towers. Within your immediate environment, try to place Wi-Fi routers at a distance from where you spend most of your time.

4. Utilize Wired Networks: Although considered old-fashioned and cumbersome, using cables to minimize EM and radiation exposure can be beneficial for long-term health.

Understanding all this is not just general knowledge; it is the core responsibility of a modern electrical engineer. Designing advanced devices is not enough. The greatest challenge of the future is to create innovations that align with human health and comfort.

The Electrical Engineering Study Program at Dian Nusantara University (UNDIRA) plays a vital role in this mission. We do not just equip students with theories of electrical circuits or telecommunication principles. We shape future engineers who are conscious of the social and health impacts of every technology they create.

Electrical Engineering students at UNDIRA are continuously encouraged and developed to innovate solutions that are not only efficient but also healthy and convenient for everyone in their daily lives. They learn how to design safer wireless systems, develop devices with the lowest possible SAR levels, and integrate the principles of Electromagnetic Safety from the design phase all the way to quality control.

The vision and mission of UNDIRA's Electrical Engineering program are to produce graduates who are not only innovative but also possess integrity in their expertise. We are committed to producing technocrats who not only build the digital future but also protect it. Join us and become part of the generation of engineers creating a smarter, faster, and, most importantly, safer digital future for all.
