Abstract

Telah dilakukan penelitian tentang percepatan tanah menggunakan Jaringan Syaraf Tiruan (JST) yang bertujuan untuk menganalisis serta memprediksi percepatan tanah di Sumatera. Penelitian ini

menggunakan data percepatan tanah yang direkam dengan accelerograph yang terdapat pada 3 stasiun di Sumatera Barat, yaitu Stasiun Geofisika Padang Panjang (PAPA), Stasiun Meteorologi Ketaping (PATA), dan Stasiun Maritim Teluk Bayur (PATU). Pengolahan data ini menggunakan metode backpropagation. Dalam pengolahan data, dilakukan dengan 2 jenis pembagian data, yaitu pembagian data dengan rasio 50:50, dimana data tahun 2016 dan 2017 digunakan sebagai target uji, selanjutnya pembagian dengan rasio 80:20, dimana data tahun 2017 digunakan sebagai target uji. Setelah dilakukan proses pelatihan dan pengujian, didapatkan bahwa pembagian data dengan rasio 80:20 mendapatkan hasil yang lebih baik daripada pembagian data dengan rasio 50:50. Secara keseluruhan pada proses pengolahan data yang telah dilakukan, dapat disimpulkan bahwa JST tidak mampu memprediksi percepatan tanah di Sumatera, hal ini dikarenakan nilai error yang didapatkan cukup besar.
