UNS — Two innovative students from Universitas Sebelas Maret (UNS) competed as the “Go To Japan” team. They proudly secured second place in the Infographics subcategory at the 2025 Student Scientific Festival (Festival Ilmiah Mahasiswa/FILM). They are Aditya Wisnu Yudha Marsudi (Undergraduate Physics) and Desnia Anindy Irni Hareva (Undergraduate Statistics). They impressed the judges with SOLID (Solar Panel-Powered IoT-Based Landslide Detection). SOLID is an eco-friendly and sustainable system designed to detect potential landslides.

“We wanted to address the serious issue of landslides in Indonesia. This natural disaster endangers around 40.9 million people living in 918 vulnerable zones. To respond to this, we developed SOLID, an innovative and environmentally friendly detection system,” Aditya explained to uns.ac.id on Thursday (24/4/2025).

SOLID combines energy-efficient solar panels with IoT technology, sending real-time alerts via WhatsApp to residents within a 10-kilometer radius. The prototype uses solar panels as its main power source. It also includes a lithium battery to provide backup energy when sunlight is unavailable.

The system includes three key sensors: soil moisture, slope inclination, and ground displacement. SOLID reads real-time data from these sensors. It issues three alert levels—“Alert,” “Warning,” and “Danger”—through WhatsApp. The system uses parameters set in the Arduino IDE to determine the appropriate alert.

Advanced Forecasting and Physical Alarms

Beyond real-time alerts, SOLID uses a Long Short-Term Memory (LSTM) algorithm to forecast landslides up to 14 days in advance. This early warning allows more time for evacuation and mitigation. In addition, the system features a physical alarm—buzzers and strobe lights—for immediate on-site awareness.

The team developed their project with valuable guidance from Dr. Ir. Sorja Koesuma, S.Si., M.Si. He provided insights on landslide indicators and technical aspects. “His mentorship provided a strong foundation. Over two months, we worked intensively on both the infographic and the SOLID prototype,” Aditya said.

Recognition at FILM 2025 and Future Aspirations

FILM 2025 hosted three main categories: Essay, Scientific Writing (LKTI), and Infographics. The event gathered over 1,800 participants from 114 universities in 22 provinces across Indonesia. The UNS team competed under the “Technology” sub-theme. It aligned with the festival’s theme: “Innovative Synergy of Youth in the Society 5.0 Era to Achieve Sustainable Development Goals (SDGs) Towards Golden Indonesia 2045.”

The competition included several selection phases, from proposal submission to semifinal and final presentations. Finalists showcased their innovations in an expo, an award ceremony, and a gala dinner.

“We’re incredibly honored to win in our first-ever national infographics competition,” Aditya shared. “This experience taught us the value of collaboration, creativity, and research in delivering impactful visual communication.”

He also encouraged fellow students to take on new challenges. “Believe in yourself, utilize your team’s strengths, and don’t hesitate to innovate. Every challenge is a chance to grow,” he added.

This achievement supports UNS’s commitment to Sustainable Development Goals, particularly SDG 4 (Quality Education) and SDG 9 (Industry, Innovation, and Infrastructure), especially in the field of disaster mitigation.
