Makalah ini membahas penelitian tentang pemanenan energi piezoelektrik (PEH) yang terksitasi oleh tumbukan pendulum di sebuah kapal akibat terinduksi gelombang laut. Variasi yang diteliti adalah horizontal 10 mm (H10), horizontal 20 mm (H20), horizontal 40 mm (H40), vertikal 10 mm (V10), vertikal 20 mm (V20), dan vertikal 40 mm (V40). Variasi tersebut dipilih karena dapat mewakili rentang kerapatan tinggi hingga rendah. Penelitian dilakukan dengan metode elemen hingga menggunakan ANSYS Workbench dengan pendekatan coupled-field transient dengan fixed support di atas dan bawah pelat. Parameter performa terbaik diambil berdasarkan nilai rata-rata VRMS. Hasil simulasi menunjukkan distribusi tegangan listrik terbesar berada di area pusat pelat akibat regangan yang lebih tinggi dibandingkan area tepi. Di antara 6 variasi, variasi H10 menghasilkan performa terbaik dengan rata-rata VRMS sebesar 24,76 V dan variasi H40 menghasilkan performa terburuk dengan rata-rata VRMS 14,19 V sehingga dapat disimpulkan bahwa semakin rapat posisi piezoelektrik, semakin efektif memanen energi.
