This study aims to create an alarm tool that can detect disasters such as earthquakes and liquefaction in Palu City. It was laboratory research conducted in Sub department of Physics Education, Tadulako University. Research and experiments with modelling tools were conducted to simulate soil conditions during the earthquake and liquefaction. The research sample was focused on soil samples that have been affected by liquefaction disasters. The method used was the waterfall with the procedures of requirements analysis, system design, implementation, and testing of Arduino programs and software as ground movement monitoring. This study indicated that a liquefaction alarm prototype using a microcontroller component in the form of Arduino Uno, soil moisture sensor, and MPU6050 sensor could detect a natural liquefaction disaster was signed by a siren sound.
