Prototipe Stasiun Curah Hujan dan Detektor Deformasi Tanah Sebagai Pendeteksi Tanah Longsor
Indonesia is one of the countries prone to landslide disaster. This because the soil in Indonesia is a lot of valleys, hills and volcanoes. This disaster is caused by several things such as rainfall and land shift. The purpose of this research is to design 2 prototypes, which is rainfall station and ground deformation detector as landslide detector. The rainfall station prototype uses a modular optocoupler sensor mounted on tipping bucket to calculate rainfall. Each tipping will calculate a resolution of 9 ml or 0.58 mm each transition and data will continue to grow until the rain stops. In ground deformation prototypes use the MPU-6050 sensor to detect movement of soil in the form of 3 axes, x, y and z angular velocity (deg / s) and acceleration (g). The highest slope has greater potential for landslides with an angle of 50 °. Both data on the prototype are sent by WSN (Wireless Sensor Network), where XBee Series 2B as transmitter and receiver. This system can provide information in the form of data in real time. As well as a notification alert in the graph if the data obtained exceeds the specified threshold, and can be accessed via web local host.
