Students of the Off-Campus Learning Program (PLK) at Universitas Negeri Yogyakarta (UNY), who are carrying out community service activities in Karangasem Hamlet, initiated the installation of Miniature Circuit Breaker (MCB) timers for street lighting in every neighborhood unit (RT). The program was implemented as an effort to improve electricity efficiency while simplifying the management of street lighting for the local community.
Through the implementation of this system, street lights can now operate automatically, turning on at 5:30 p.m. and turning off at 5:30 a.m. With this time-based automation system, residents no longer need to manually switch the lights on and off every day.
One of the PLK UNY 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 disconnect electric current in the event of overloads or electrical disturbances. In this program, the device was integrated with a timer system so that it functions not only as a safety mechanism but also as an automatic controller for street light operating schedules.
“Through the installation of this MCB timer, street lights can operate more effectively and safely. This system helps the community because residents no longer need to operate the lights manually every day,” explained Ferdi.
The secretary of the PLK UNY community service group, Ria Anggraeni, added that the program was designed to provide convenience while increasing the effectiveness of energy use within the community. According to her, the automatic system can 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, accompanied by socialization and educational sessions for residents regarding how the timer system works, its benefits, and how to manage the device. 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, stated that the automatic street lighting system greatly helped daily activities.
“Now the street lights turn on and off automatically, so we no longer worry about forgetting to switch them on or off. The environment also feels brighter and safer at night,” he said.
In addition to simplifying operations, the timer system also helps control electricity consumption because the lights only operate when needed. This energy efficiency is expected to create long-term impacts in developing a more energy-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 beneficial technology, PLK UNY students hope this program can become a concrete step toward improving the quality of life in the community while also raising awareness about the importance of efficient and sustainable energy use in rural areas.
