- This study examines the application of a landslide disaster monitoring system based on soil activity information that utilizes humidity, temperature, and accelerometer sensors. An artificial highland was built as the research object, and the landslide process was triggered by supplying the system with continuous artificial rainfall. The soil activities were observed through its slope movement, temperature, and moisture content, utilizing an accelerometer, temperature, and humidity sensors both in dry and wet conditions. The system could well observe the soil activities, and the obtained data could be accessed in real-time and online mode on a website. The time delay in sending the data to the server was 2 seconds. Moreover, the characteristics of soil porosity and its relevance to soil saturation level due to water pressure were studied as well. Kinetic study showed that the water adsorption to soil followed the intraparticle diffusion model with a coefficient of determination R2 0.99043. The system prototype should be used to build the information center of disaster mitigation, particularly in Indonesia.
- Artikel ini mengkaji aplikasi sistem pemantauan bencana tanah longsor berdasarkan informasi aktivitas tanah yang memanfaatkan sensor kelembapan, suhu, dan accelerometer. Sebuah purwarupa dataran tinggi digunakan sebagai objek studi tanah longsor dan perubahan keadaan tanah dipantau dengan memberikan hujan buatan secara kontinyu kepada sistem. Aktivitas tanah dipantau berdasarkan data kemiringan, suhu, dan juga kelembapan tanah, baik saat keadaan kering maupun basah. Hasil pengukuran menunjukkan bahwa sistem pemantauan dapat merekam aktivitas tanah dengan baik dan informasi tersebut dapat diakses secara online dan real-time melalui sebuah situs web. Estimasi waktu tunda pengiriman data menuju server adalah 2 detik. Karakteristik porisitas tanah dan relevansinya terhadap tingkat saturasi tanah karena tekanan air telah dikaji. Hasil studi kinetik menunjukkan bahwa proses adsorpsi air ke tanah mengikuti model kinetik difusi intra partikel, dengan coefficient of determination R2 sebesar 0,99043. Sistem pemantauan yang dirancang diharapkan menjadi purwarupa awal untuk terbentuknya pusat informasi mitigasi bencana tanah longsor yang dapat diterapkan, khususnya di Indonesia.
