Abstract

Penelitian ini mengkaji emisi radiasi elektromagnetik EM dari kereta lintas raya terpadu pada berbagai kondisi operasional dan polarisasi antena. Pengukuran dilakukan dalam empat kondisi operasional: percepatan, perlambatan, kecepatan tinggi, dan kondisi statis, menggunakan polarisasi antena vertikal dan horizontal. Analisis terhadap data pengukuran menunjukkan adanya variasi signifikan dalam level emisi pada berbagai frekuensi. Pada kondisi percepatan dengan polarisasi vertikal, level emisi meningkat pada beberapa frekuensi, terutama pada 143.67 MHz dan 392.23 MHz, dengan peningkatan mencapai 71.16 dBuV/m dan 81 dBuV/m. Pergeseran frekuensi yang signifikan teramati pada kondisi perlambatan, diduga kuat disebabkan oleh efek Doppler. Secara umum, level emisi sebagian besar masih berada di bawah batas standar EN 50121-2, meskipun beberapa frekuensi mendekati atau sedikit melebihi batas tersebut. Perbandingan antara ambient noise pagi dan sore hari menunjukkan perbedaan signifikan pada beberapa frekuensi, dengan peningkatan level emisi yang jelas saat kereta melintas. Hal ini menunjukkan bahwa emisi radiasi elektromagnetik dari kereta lebih tinggi daripada ambient noise pada frekuensi tertentu, yang diakibatkan oleh sistem kelistrikan kereta. Penelitian ini menekankan pentingnya pemantauan dan pengelolaan emisi radiasi elektromagnetik dari kereta lintas raya terpadu untuk memastikan kepatuhan terhadap standar EMC dan mengurangi potensi gangguan terhadap perangkat elektronik di sekitar jalur kereta.

This research examines the electromagnetic (EM) radiation emissions from an integrated urban rail system under various operational conditions and antenna polarizations. Measurements were taken under four operational conditions: acceleration, deceleration, high speed, and static conditions, using vertical and horizontal antenna polarizations. The analysis of the measurement data showed significant variations in emission levels at various frequencies. In the acceleration condition with vertical polarization, emission levels increased at several frequencies, particularly at 143.67 MHz and 392.23 MHz, with increases reaching 71.16 dBuV/m and 81 dBuV/m. Significant frequency shifts were observed in the deceleration condition, strongly suspected to be caused by the Doppler effect. Overall, most emission levels remained below the EN 50121-2 standard limits, although some frequencies approached or slightly exceeded these limits. Comparison between morning and evening ambient noise showed significant differences at several frequencies, with clear increases in emission levels when the train passed. This indicates that the electromagnetic radiation emissions from the train are higher than ambient noise at certain frequencies, caused by the train's electrical systems. This study emphasizes the importance of monitoring and managing electromagnetic radiation emissions from integrated urban rail systems to ensure compliance with EMC standards and to reduce potential interference with electronic devices around the rail tracks.
