ABSTRAK Tanah longsor merupakan tergelincirnya satu blok (tanah) terhadap tanah yang lain. Tanah Longsor dapat dideteksi dengan perubahan tingkat kemiringan tanah. Penelitian ini menunjukkan desain dan realisasi alat pendeteksi tingkat kemiringan tanah menggunakan sensor potensio linier berbasis mikrokontroler ATMega 8535. Sistem bekerja dengan 4 (empat) unit sensor potensio linier. Sensor ditempatkan pada setiap sudut bagian atas sistem. Sehingga sensor dapat mendeteksi kemiringan empat arah. Setiap perubahan kemiringan sistem, beban akan menggeser kawat ke atas dan bawah. Pergeseran kawat ini yang menyebabkan resistansi pada sensor berubah. Nilai keluaran sensor dihubungkan dengan rangkaian pembagi tegangan sebelum masuk ke ADC. Nilai keluaran yang diperoleh oleh sistem berubah sesuai dengan arah dan perubahan tingkat kemiringan. Hasil selanjutnya ditampilkan pada LCD dan disimpan pada micro-sd. Hasil penelitian menunjukkan bahwa alat yang digunakan dapat mendeteksi perubahan tingkat kemiringan 00 hingga 250. Kata Kunci: Kemiringan, Tanah Longor, Sensor, Potensio Linier ABSTRACT Landslide is a block (mass) slipping against another mass. Landslides could be detected by determining changes in the slope level of the ground. This experiment demonstrated a design and realization of ground slope level detector using ATMega 8535 microcontroller - based linear potentio sensor. The system worked with four units of linear potentio sensors. The sensors were placed in each corner on the top side of the system, so that the sensors were able to detect the slope in four directions. For every change of the system slope, a burden would shift the wire towards the top and the bottom. The wire shift would trigger a change in resistance in the sensors. The output value of the sensors was connected to a voltage divider circuit before entering ADC. Therefore, the output value obtained from the system changed in accordance with the directions and the change in the slope level. Then, the output value were displayed on LCD and was stored in a micro SD. According to the experiment, the tool was capable of detecting change in the slope level measuring from 00 to 250. Keywords: Slope, Landslide, Sensors, Linear Potentio
