INTISARI
Transportasi kereta api menghadapi tantangan, antara lain rel tekuk akibat metode Continuous Welded Rail (CWR). Pemasangan CWR memiliki kelemahan seperti tekanan termal, memerlukan Suhu Netral Rel (RNT) tertentu. Perubahan suhu yang ekstrim menimbulkan kekhawatiran, menyebabkan kerusakan dan berkurangnya ketersediaan layanan kereta. Tindakan preventif sangat penting untuk mencegah terjadinya tekuk rel akibat perubahan suhu yang ekstrem. Penelitian ini bertujuan untuk meninjau teknologi pemantauan jarak jauh yang canggih untuk rel tekuk. Metodologi yang digunakan yaitu studi tinjauan literatur, pengumpulan data sekunder, dan analisis teknologi yang menjanjikan. Penelitian ini mengeksplorasi dua teknologi yang menjanjikan untuk pemantauan jarak jauh rel tekuk: metode visi non-kontak dengan teknologi Digital Image Correlation (DIC) dan sensor Fiber Bragg Grattings (FBG). Teknologi DIC mengukur deformasi dan perubahan bentuk tanpa kontak fisik, sehingga mengurangi kerusakan pada sistem rel. Sensor FBG mendeteksi perubahan suhu dan deformasi pada objek atau struktur, memungkinkan distribusi beban dan analisis tegangan tarik.
