A system designed to monitor, detect and provide early warning of landslide hazards. This system is equipped with technical sensors and human sensors. Technical sensors consist of extensometers (lateral, vertical and rotational soil movement detection devices). Tiltmeter (a device to detect changes in the position of the slope of the ground surface/rocks on the slope). Ultrasonic water level (a device that detects changes in water level in river channels) that is integrated and connected to one server with digi tal memory. Human sensors are designed to strengthen technical sensors, based on observations in the field carried out by communities or residents in landslide-prone locations. GAMA-EWS is considered more effective because all components of this system work automatically through a telemetry system, have an independent power source (solar panels), and are wireless. This is designed because considering that areas with potential for landslide disasters are often in places that are difficult to reach. The downstream company and distributor of GAMA-EWS is PT. Gama Multi Usaha Mandiri (GMUM).
