Abstract

Lebar rel kereta api yang tidak standar mengakibatkan kereta anjlok. Dikarenakan rel menerima beban dari roda kereta api secara kontinu selama kereta beroperasi. Inspeksi rel dilakukan oleh tenaga manusia atau PPJ (Petugas Penilik Jalur) menggunakan track gauge master, untuk mengukur lebar rel kereta api. Pengukuran lebar rel secara manual menjadi permasalahan, mengakibatkan petugas berjalan disepanjang rel kereta api sehingga kurang efisien dari segi waktu dan tenaga, serta dapat membahayakan keselamatan. Solusi dari permasalahan tersebut adalah dibutuhkan perangkat untuk mengukur lebar rel yang memudahkan petugas. Perangkat pengukur lebar rel menggunakan sensor laser. Penggunaan sensor laser dalam pengukuran memanfaatkan selisih waktu tempuh sinyal yang dipantulkan dan diterima oleh sensor, kemudian diolah menjadi nilai jarak. Nilai jarak disaring menggunakan metode kalman filter. Pengujian keakuratan jarak dibandingkan dengan alat ukur laser distance meter. Sensor laser dikalibrasi untuk meminimalisir selisih pengukuran (error) dari hasil pembanding. Hasil penelitian didapatkan akurasi error pada sensor laser sebesar 1,5%. Akurasi error menjadi 0,11% setelah menggunakan kalman filter.

Abstract

Rail quality decreases directly in proportion to the operating time of the train since the rail is loaded from the train wheels. Railroad tracks are inspected by PPJ (Track Inspector) by using a track gauge master to measure slope. Manually operated devices cause PPJ to run along the railroad between stations, causing accidents and requiring relatively long operating times. Using a device that measures the slope of railroad tracks is a more effective solution to these problems. The device uses a gyroscope sensor and GPS module to locate non-standard rails. A complementary filter is applied to the converted pitch and roll values. A slope measuring instrument was used to test the accuracy of pitch and roll angles. Gyroscope sensors are calibrated to prevent measurement errors (errors). Based on the results, the gyroscope sensor had an accuracy error of 0.20° in pitch and 0.27° in a roll. A complementary filter reduces error accuracy to 0.06° for pitch and 0.08° for roll. Its accuracy compared to smartphone GPS is 5.38 meters, while its accuracy compared to the actual location is 7.74 meters.
