Students participating in the Off-Campus Learning Program (PLK) from Universitas Negeri Yogyakarta who carried out community service activities in Karangasem Hamlet initiated a program to install Miniature Circuit Breaker (MCB) timers for street lights in every neighborhood unit (RT). The program was implemented to improve electricity efficiency while simplifying the management of street lighting for local residents.

Through the implementation of this system, street lights can now operate automatically—turning on at 5:30 PM and turning off at 5:30 AM. With this time-based control system, residents no longer need to manually switch the lights on and off every day.

One of the UNY PLK team members, Ferdi Nofandaru, who was responsible for the MCB timer installation, explained that a Miniature Circuit Breaker (MCB) is an electrical safety device designed to cut off electrical current in the event of overloads or electrical disturbances. In this program, the device was integrated with a timer system, enabling it to function not only as a safety mechanism but also as an automatic controller for street light operating hours.

“Through the installation of this MCB timer, street lights can operate more effectively and safely. This system helps residents avoid having to manually operate the lights every day,” explained Ferdi.

The secretary of the UNY PLK Mengabdi group, Ria Anggraeni, added that the program was designed to provide convenience while improving energy efficiency within the local community. According to her, the presence of this automatic system helps reduce the risk of negligence in operating street lights while also creating a safer and more comfortable environment for residents.

The installation process was carried out gradually in each neighborhood unit (RT) and accompanied by community outreach regarding how the system works, its benefits, and the timer settings. This educational effort was intended to ensure that residents could understand and utilize the system optimally and sustainably.

Positive responses also came from local residents who directly experienced the benefits of the program. One resident, Mr. Rouf, expressed that the automatic lighting system had been highly beneficial in daily life.

“Now the street lights turn on and off automatically, so we no longer have to worry about forgetting to switch them on or off. The neighborhood also feels brighter and safer at night,” he said.

In addition to simplifying operation, the use of the timer system also helps control electricity consumption since the lights are turned on only when needed. This energy efficiency is expected to create a long-term impact in building a more electricity-saving, safe, and environmentally friendly community.

This community service program also supports the achievement of the Sustainable Development Goals (SDGs), particularly SDG 7 (Affordable and Clean Energy) through efficient energy utilization, SDG 11 (Sustainable Cities and Communities) by creating a safe and comfortable environment, and SDG 12 (Responsible Consumption and Production) through reducing electricity waste.

Through the use of simple yet impactful technology, UNY PLK students hope that this program can become a concrete step toward improving community quality of life while fostering awareness of the importance of efficient and sustainable energy use in rural areas.
