What to Know About EroSlide, BRIN's New Landslide Detection System
BRIN develops EroSlide, a sensor system that reads signs of erosion and landslides to support early warning system.
Jakarta - In a groundbreaking development, researchers from the National Research and Innovation Agency (BRIN) have introduced a novel system known as EroSlide to predict potential landslides and erosion. The smart detection system utilizes a variety of sensors, such as rainfall amounts, sediment weight, water flow rates, slope inclines, soil pH, moisture levels, and temperature to forecast risks.
Principal Expert Engineer at BRIN Mineral Technology Research Center, Nendaryono Madiutomo, explained that EroSlide stands for erosion, sliding, and deposition, highlighting that erosion is the primary cause of landslides.
The system comprises a cubic meter-sized box filled with sensors, which is then surrounded by data processors, transmission networks, batteries, and solar panels to ensure effective data collection and transmission. A team of 15 researchers from various BRIN centers placed these sensors in the box, taking into account similar land conditions like slope and soil type.
The processed sensor data is sent to users via 4G or 5G cellular networks, with an option for radio modem transmission in areas without cellular signals. The data collection interval can be customized, ranging from daily, hourly, per minute, to even seconds. The data can be displayed in a table or real-time graphical form. EroSlide data can be utilized to categorize regional conditions, such as rainfall ranges or erosion levels.
The BRIN team anticipates that the same data can help create maps of erosion, landslide, and deposition risks.
Colors are used to grade hazards, with green indicating safety, yellow signaling caution, and red demanding an evacuation. Nendaryono mentioned that similar grading can also be achieved through sirens. This erosion and landslide early warning system was tested in Bandung for 10 months, from September 2025 to June 2026, with further trials planned in Subulussalam, Aceh, in October or November.
