Balikpapan, 2025 – Students from the Institut Teknologi Kalimantan (ITK) once again made a real impact through a meaningful community service project! This time, a collaborative team from the Civil Engineering and Architecture study programs joined forces to raise public awareness about landslide hazards and to install solar-powered street lighting in Bukit Batakan Permai II Housing Complex, Manggar Subdistrict, East Balikpapan.

This initiative is more than just technology in action—it’s a step toward safety, energy efficiency, and environmental sustainability in hillside areas prone to disasters.

Raising Awareness of Landslide Hazards

Bukit Batakan Permai II is located in a hilly area with steep slopes that can be dangerous if not properly managed. To address this, the ITK team organized a landslide awareness campaign involving residents, local leaders, and village officials. Participants learned about the causes of slope instability—such as heavy rainfall and reduced vegetation—and simple ways to mitigate the risks.

“We want the community not only to recognize potential hazards but also to understand how to prevent them early on,” said Dwi Aneka Kartini, S.T., M.T., a Civil Engineering lecturer and project supervisor.

Solar Streetlights: Bright, Safe, and Energy-Efficient

Beyond landslide awareness, residents also faced another issue—poor lighting in several steep areas, which often led to safety concerns at night. To solve this, the ITK team designed and installed solar-powered streetlights, providing a sustainable and cost-free lighting solution. These lights absorb solar energy during the day and automatically illuminate the streets at night.

“With solar power, residents don’t have to worry about electricity costs. The lamps will continue to shine even during power outages,” explained Muhammad Huzair, S.T., M.T., one of the supervising lecturers.

From Site Survey to On-Ground Implementation

Before installation, the team conducted a field survey with the local neighborhood leader (RT) to identify dark and high-risk areas. They then prepared all necessary materials, including solar panels, LED lamps, steel poles, and concrete foundations.

Students worked hand in hand with residents to test and ensure the lighting system worked optimally. The results showed that the installed lights reached an illumination level of 9 lux bright enough to light up previously dark areas. 

Real Impact for the Community

Today, Bukit Batakan Permai II is brighter and safer. Residents say they feel more comfortable walking at night and have become more aware of the benefits of renewable energy.

“It used to be scary walking here at night because it was so dark. Now it’s safer, and people are more aware of the importance of solar energy,” said Mr. Sabriansyah, Head of the local neighborhood association (RT).

Beyond social benefits, this project also introduced the community to green technology, helping reduce carbon emissions and promoting long-term energy efficiency. 

Toward a Smart and Sustainable Community

This initiative reflects ITK’s strong commitment to supporting the Sustainable Development Goals (SDGs), particularly in clean energy and disaster resilience. The collaboration between Civil Engineering and Architecture students also highlights the importance of a multidisciplinary approach in addressing real social challenges.

“This program isn’t just about installing lights—it’s an educational effort to build a resilient and environmentally conscious community,” added Zahrotur Rahmania Firliani, S.Ars., a lecturer from the Architecture Department.

A Word of Thanks

This social innovation project was made possible through the support of the Institute for Research and Community Service (LPPM ITK), the supervising lecturers, and the active participation of Bukit Batakan Permai II residents.

ITK hopes this collaboration between academia and the community will continue to grow, creating an environment that is safe, energy-independent, and sustainable.
