ABSTRACTDesign of Landslide Potential Warning System and Land Shifting Using Telemetry Method: According to the 2019 BNBP Performance Report, landslides are the fourth most frequent disaster in Indonesia, so we need a telemetry tool for land shifting. This system consists of ATMega328 Microcontroller, Linear Variable Differential Transformer sensor and rheostat, accelerometer sensor, rain gauge tipping bucket, and HC-12 wireless communication module. Normally, LVDT sensor reads ground shift in the 0-20 mm range, rheostat shifting up to 66 mm, accelerometer sensor reads data less than 20 deg and rain gauge tipping bucket sensor generates the amount of rainfall below 50 mm/hour which is sent data regularly to user. Warning alarms installed in these prone area will sound if the LVDT sensor reads ground shift30 mm, rheostat51 mm, accelerometer sensor reads data more than 45°, and rain gauge tipping bucket sensor reads more than 70 mm/hour. This test produces measurable parameter data so that it can be displayed and provide warning information.Keywords: alarm warning; ATMega 328; land shifting; landslides; telemetry.ABSTRAKMenurut Laporan Kinerja BNBP 2019, tanah longsor merupakan bencana yang sering terjadi urutan keempat di Indonesia, sehingga perlu suatu alat telemetri terhadap pergeseran tanah. Sistem ini terdiri atas Mikrokontroler ATMega328, sensor Linear Variable Differential Transformer dan rheostat, sensor accelerometer, sensor rain gauge tipping bucket, dan modul komunikasi wireless HC-12. Normalnya, sensor LVDT membaca pergeseran tanah pada range 0-20 mm, rheostat mampu melakukan pergeseran hingga 66 mm, sensor accelerometer membaca data kurang dari 20 deg, dan sensor rain gauge tipping bucket menghasilkan jumlah curah hujan dibawah 50 mm/jam yang kemudian data dikirim secara rutin ke user. Alarm peringatan yang terpasang di daerah rawan tersebut akan berbunyi jika sensor LVDT membaca pergeseran tanah 30 mm, rheostat 51 mm, sensor accelerometer membaca data lebih dari 45 derajat, dan sensor rain gauge tipping bucket membaca data lebih dari 70 mm/jam. Pengujian ini menghasilkan data parameter yang terukur sehingga dapat ditampilkan dan memberikan informasi peringatan.Kata Kunci: alarm peringatan; ATMega 328; pergeseran tanah; tanah longsor; telemetri
