On March 24, 2024, Cipongkor Village in West Bandung was shaken by a landslide tragedy that occurred while the residents were deep in sleep. As of April 6, 2024, eight victims have been found, while two others are still being searched for. The Research and Community Service Institute (LPPM) team from the Bandung Institute of Technology (ITB) reported that 53% of the affected residents show symptoms of PTSD (Post-Traumatic Stress Disorder), highlighting the profound psychological impact of the disaster.
We had the opportunity to contribute to the disaster relief efforts through aerial mapping with the SIGAB PERSIS volunteers at the site. With an area spanning nearly 200 hectares and challenging geographical conditions, we decided to use the VTOL (Vertical Take-Off and Landing) RAYBE drone we developed. This drone is designed to map large areas in a single flight, ideal for situations and conditions like those in Cipongkor Village.
Mapping Challenges
Mapping was not easy. The disaster location, situated in a valley surrounded by hills, was very prone to strong winds, coupled with foggy weather and rain, making the first flight produce many photos obscured by fog. Limitations of space for take-off and landing also added to the difficulties. However, with clearer weather on the second day, RAYBE successfully produced high-quality photos in less than 15 minutes.
Mapping Results
From the processed data, we obtained a visual disaster map complete with its 3D visualization. The comparison of maps from RAYBE with Google Map before the disaster provided a clear picture of the landslide's impact on Cipongkor Village. This map greatly assisted the disaster relief team in searching for the still missing victims and identifying the affected houses.
Reflection and Hope
Although this mapping mission is considered a success, we feel the need to apologize for only being able to conduct the mapping four days after the disaster occurred, due to the limited units available at our workshop at the time. Going forward, we hope technology like the VTOL RAYBE drone can be available and ready to operate in all disaster-prone areas of Indonesia, so that mitigation can be carried out more quickly and effectively.
The tragedy in Cipongkor Village reminds us all of the importance of readiness and quick response in facing natural disasters. Through innovation and technology, such as landslide disaster mapping with drones, we can make a significant contribution to disaster relief efforts. We pray that the still missing victims can be found soon and that the residents of Cipongkor Village are given the strength to get through this difficult time.
