RANCANGAN ALAT PEMBACA SIGNAL MODUL MODULATION SIGNAL GENERATOR DVOR MARU 220 MENGGUNAKAN ARDUINO UNO

Penelitian ini bertujuan merancang alat pembaca sinyal frekuensi Modul Modulation Signal Generator (MSG) DVOR MARU 220 berbasis mikrokontroler Arduino Uno ATmega328P. Alat dirancang untuk mendeteksi tiga jenis sinyal, yaitu 30 Hz (sinyal rotasi), 720 Hz (sinyal variabel), dan 1020 Hz (sinyal referensi). Sistem memanfaatkan pembacaan sinyal analog melalui pin A0, A1, dan A2 Arduino,kemudian data dikonversi menjadi nilai digital yang divisualisasikan secara real-time menggunakan antarmuka PyQt5 di komputer. Tahapan perancangan meliputi pembuatan rangkaian hardware, pemrograman mikrokontroler untuk akuisisi data, serta pengembangan aplikasi desktop dengan fitur tampilan grafik dan kontrol parameter. Dalam proses perancangan, peneliti menggunakan metode Research and Development (R&D) berbasis model ADDIE yang mencakup tahapan Analysis,Design, Development, Implementation, dan Evaluation secara sistematis untuk memastikan produk yang dihasilkan sesuai kebutuhan pengguna dan spesifikasi teknis alat navigasi. Alat telah dilaksanakan pengujian di AirNav Repair Center
Yogyakarta dan menunjukkan hasil pembacaan sinyal yang stabil dan sesuai spesifikasi frekuensi modul MSG. Hasil pengujian membuktikan alat mampu menampilkan data output secara akurat dan memudahkan teknisi dalam proses
pemantauan dan kalibrasi peralatan. Rancangan ini dinilai efektif digunakan sebagai alat bantu portable untuk mendukung perbaikan dan pengujian Modul MSG DVOR
MARU 220 secara lebih praktis.

============================================================
This research aims to design a frequency signal reader device for the Modulation Signal Generator (MSG) DVOR MARU 220 based on the Arduino Uno ATmega328P microcontroller. The device is designed to detect three types of signals, namely 30 Hz (rotation signal), 720 Hz (variable signal), and 1020 Hz(reference signal). The system utilizes analog signal acquisition through the Arduino’s A0, A1, and A2 pins, which are then converted into digital values and visualized in real-time using a PyQt5 interface on a computer. The design stages include hardware circuit development, microcontroller programming for data acquisition, and the development of a desktop application with graphical display and parameter control features. In this design process, the researcher employed a Research and Development (R&D) approach based on the ADDIE model, which systematically consists of Analysis, Design, Development, Implementation, and Evaluation phases to ensure that the resulting product meets user needs and the technical specifications of navigation equipment. The device was tested at the AirNav Repair Center Yogyakarta and demonstrated stable signal readings consistent with the MSG module’s frequency specifications. The test results confirmed that the device can accurately display output data and assist technicians in monitoring and calibrating equipment. This design is considered effective as a
portable auxiliary tool to support the maintenance and testing of the MSG DVOR MARU 220 module in a more practical manner.
