Abstract
Penelitian ini bertujuan untuk melakukan improvisasi alat uji dinamis Active Air Suspension sehingga dapat digunakan sebagai media pengujian percepatan vertikal pada half-car model dengan variasi beban. Improvisasi dilakukan melalui penyempurnaan sistem mekanik, sistem pneumatik, sistem kontrol, serta integrasi sensor sehingga seluruh komponen alat uji dapat bekerja secara terpadu. Mekanisme poros engkol yang digerakkan oleh motor listrik digunakan untuk mensimulasikan kondisi jalan bergelombang, sedangkan variasi beban pengujian yang digunakan sebesar 24 kg, 28 kg, dan 32 kg Pengambilan data dilakukan menggunakan sensor akselerometer MPU6050 untuk mengukur percepatan vertikal, sensor ultrasonik untuk mengukur perubahan ketinggian suspensi, serta sensor tekanan untuk memantau tekanan udara pada air spring secara real-time. Seluruh data diproses menggunakan mikrokontroler Arduino sebagai pengendali sistem sehingga kondisi pengujian dapat berlangsung secara terintegrasi. Kinerja alat uji dievaluasi berdasarkan nilai Root Mean Square (RMS) percepatan vertikal sesuai dengan standar ISO 2631 untuk menilai tingkat kenyamanan pada setiap variasi beban. Hasil penelitian menunjukkan bahwa improvisasi yang dilakukan berhasil meningkatkan fungsi alat uji sehingga mampu digunakan untuk melakukan pengujian percepatan vertikal pada half-car model. Selain itu, hasil analisis RMS menunjukkan bahwa variasi beban memengaruhi respons percepatan vertikal sistem suspensi dan alat uji yang telah diimprovisasi dapat dimanfaatkan sebagai media penelitian maupun pengembangan sistem suspensi udara aktif di lingkungan laboratorium.

This research aims to improve the Active Air Suspension dynamic test equipment so that it can be used as a medium for testing vertical acceleration on a half-car model with varying loads. Improvements were made through refinement of the mechanical system, pneumatic system, control system, and sensor integration so that all components of the test equipment can work together. A crankshaft mechanism driven by an electric motor was used to simulate bumpy road conditions, while the test load variations were 24 kg, 28 kg, and 32 kg. Data was collected using an MPU6050 accelerometer sensor to measure vertical acceleration, an ultrasonic sensor to measure changes in suspension height, and a pressure sensor to monitor air pressure in the air spring in real time. All data was processed using an Arduino microcontroller as the system controller, ensuring an integrated testing environment. The performance of the test equipment was evaluated based on the Root Mean Square (RMS) value of vertical acceleration in accordance with the ISO 2631 standard to assess comfort levels under each load variation. The results showed that the improvements successfully improved the function of the test equipment, making it suitable for testing vertical acceleration on a half-car model. In addition, the results of the RMS analysis show that load variations affect the vertical acceleration response of the suspension system and the improvised test equipment can be used as a medium for research and development of active air suspension systems in a laboratory environment.
