Penelitian ini bertujuan untuk menganalisis karakteristik gelombang yang dihasilkan oleh sistem pembangkit gelombang mekanis menggunakan aktuator pneumatik dengan dua variasi bentuk piston, yaitu piston datar dan piston lengkung. Pengujian dilakukan dalam skala laboratorium dengan tiga variasi waktu aktuasi: 400 ms - 200 ms, 300 ms - 300 ms, dan 300 ms - 150 ms. Hasil penelitian menunjukkan bahwa bentuk piston mempengaruhi parameter gelombang, seperti tinggi gelombang, energi, dan daya. Piston datar menghasilkan gelombang dengan tinggi rata-rata 0,0993 m dan energi 12,208 J/m, namun dengan kestabilan yang lebih rendah (CV = 10,16%). Sebaliknya, piston lengkung menghasilkan gelombang dengan tinggi lebih rendah (0,0677 m) tetapi menunjukkan kestabilan yang lebih baik dengan nilai CV sebesar 9,8%. Penelitian ini menyimpulkan bahwa piston datar lebih efektif dalam menghasilkan amplitudo dan energi gelombang yang tinggi, sedangkan piston lengkung lebih stabil secara statistik. Sistem ini dapat dikembangkan lebih lanjut untuk aplikasi simulasi gelombang dengan meningkatkan kontrol tekanan otomatis.
