Abstract

Suatu sistem peringatan dini tanah longsor berbasis SMS telah dirancang-bangun untuk mendeteksi dan menginformasikan kepada masyarakat lokasi tanah longsor. Metode yang digunakan adalah metode penginderaan berat dengan sistem sensor terdiri dari sensor jarak VL53L00X (objek pantul berupa cermin) dan pegas (dengan panjang 9 cm, diameter 2 cm dan konstanta pegas 62,39 N/m). Ketika terjadi pergeseran tanah dalam arah bidang gelinciran, ujung atas pegas akan tertekan oleh gaya berat bidang tanah yang bergeser sehingga jarak objek pantul dengan sensor semakin dekat. Akibatnya, jarak yang dideteksi sensor semakin besar. Hasil uji menunjukkan bahwa prototype mampu mendeteksi pergeseran tanah permukaan dalam rentang 1 hingga 7 cm. Selain itu, sistem ini juga mampu mengirim SMS untuk status siaga II (pergeseran tanah sebesar 2,39 cm), siaga III (3,17 cm), dan bahaya (4,11 cm; bunyi alarm).
