Abstract

Angkutan kereta api mempunyai karakteristik dalam pola pengoperasiannya satu petak blok hanya diperbolehkan dilewati oleh satu sarana kereta api yang keselamatannya dijamin oleh sistem persinyalan perkeretaapian. Sistem persinyalan existing di Indonesia saat ini menggunakan penunjuk aspek sinyal wayside dan belum dilengkapi dengan sistem peringatan dan proteksi terhadap pelanggaran aspek sinyal tidak aman / SPAD (Signal Pass At Danger) maupun pelanggaran batas kecepatan. Untuk meningkatkan keselamatan perjalanan mutlak diperlukan peralatan pemberi peringatan kepada masinis terhadap pelanggaran aspek sinyal dan pelanggaran pembatasan kecepatan. Penelitian ini membahas tentang perhitungan profil pengereman pada lokomotif diesel electric seri CC201 dan desain prototype Anti- Collition Device (ACD) dengan menggunakan sistem induksi Audio Frekuensi (AF) dengan menggunakan pengkodean Dual Tone Multiple Frequency (DTMF) serta sistem kontrol Mikrokontroller tipe Atmel AT89S52. Berdasarkan hasil analisa jarak pengereman pada kecepatan 120 Km/jam dengan menggunakan metode minden, sensor AF dipasang pada jarak 1.168,79 meter sebelum sinyal masuk. Berdasarkan hasil pengukuran intensitas sinyal yang diterima Sensor lokomotif DTMF, sinyal yang paling besar yaitu pada jarak celah antar sensor AF dengan jarak 80 mm., sedangkan untuk tingkat pembacaan paling rendah yaitu pada jarak 120mm.

Abstract

Railroad transportation has characteristics in the pattern of operation that a block block is only allowed to be passed by a train facility whose safety is guaranteed by the railroad signaling system. The existing signaling system in Indonesia currently uses a wayide signal aspect indicator and has not been equipped with a warning and protection system against violations of the unsafe signal aspect / SPAD (Signal Pass At Danger) or speed limit violations. To improve travel safety absolutely requires warning equipment for drivers about violations of signal aspects and violations of speed restrictions. This study discusses the calculation of the braking profile on the CC201 series electric locomotive and the Anti-Collition Device (ACD) prototype design using the Audio Frequency (AF) induction system using Dual Tone Multiple Frequency (DTMF) coding as well as the Atmel AT89S52 type Microcontroller control system. Based on the analysis of the braking distance at a speed of 120 Km / h using the minden method, the AF sensor is installed at a distance of 1,168.79 meters before the incoming signal. Based on the measurement results of the signal intensity received by the DTMF locomotive sensor, the biggest signal is at the gap gap between the AF sensors with a distance of 80 mm, while for the lowest reading level at a distance of 120mm.
