Abstract

Acoustic transducer is a source level component in the sonar equation that is indispensable as an underwater acoustic energy source, with a certain emission pattern called beamforming. In this research, we designed the construction of a driver circuit to trigger a piezoelectric (PZT) transducer to produce an acoustic energy beam for the purpose of detecting underwater targets. The manufacture of an acoustic driver with a simple working principle has been carried out to provide transmit (TX) and receive (RX) commands. The RX module will receive the acoustic signal from the TX and the results are recorded for analysis. The mixing of the information signal with noise makes the information obtained cannot be directly verified so that a signal processing process is needed to be able to separate the information signal and noise. Calibration using a spherical target was carried out to determine the detection results and the acoustic intensity level. Signal analysis and visualization methods use Fast Fourier Transform (FFT) and wavelets.

Abstract

Penelitian ini berfokus pada pengembangan alat pengukuran kedalaman yang akurat untuk aplikasi survei hidroakustik, mengingat pentingnya data kedalaman yang tepat dalam berbagai kegiatan maritim. Alat yang dirancang adalah Single Beam Echosounder (SBES) yang memanfaatkan teknologi piezoelectric dan dilengkapi dengan band pass filter berbasis microcontroller Raspberry Pi Pico. Metode penelitian yang digunakan adalah deskriptif kuantitatif, yang melibatkan pengamatan dan pengukuran di dua lokasi berbeda, yaitu kolam renang dan laut. Hasil pengujian menunjukkan bahwa alat ini memiliki penyimpangan kalibrasi yang signifikan, yaitu 7 meter di kolam renang dan 1 meter di laut, yang menunjukkan bahwa alat ini belum memenuhi standar survei yang ditetapkan oleh International Hydrographic Organization (IHO). Kesimpulan dari penelitian ini adalah bahwa meskipun alat yang dikembangkan menunjukkan potensi untuk digunakan dalam survei hidroakustik, masih diperlukan perbaikan lebih lanjut untuk meningkatkan akurasi dan kinerja alat agar dapat berfungsi secara optimal. Penelitian ini diharapkan dapat memberikan kontribusi dalam pengembangan teknologi pengukuran kedalaman yang lebih baik di masa depan, serta menjadi referensi bagi penelitian selanjutnya di bidang hidroakustik dan teknologi maritim
