Abstract
Sensor serat optik berbasis singlemode-multimode-singlemode (SMS) telah banyak dikembangkan dalam berbagai aplikasi. Penginderaan akustik bawah air menjadi aplikasi penting dari sensor serat optik karena gelombang cahaya dan elektromagnetik mengalami atenuasi besar dan jarak rambat pendek di air, sedangkan gelombang akustik memiliki atenuasi lebih kecil dan mampu merambat lebih jauh di perairan yang keruh. Penelitian ini bertujuan untuk menganalisis pengaruh variasi ketebalan diafragma silicone rubber pada kinerja sensor deteksi suara bawah air berbasis serat optik singlemode–multimode coreless-singlemode (SMS). Sensor SMS dipilih karena keunggulannya dalam transmisi data yang tinggi dan sensitivitas yang baik terhadap perubahan tekanan akustik. Variasi ketebalan diafragma silicone rubber yang diuji adalah 0.5 mm, 1 mm, dan 2 mm. Penelitian ini menggunakan metode eksperimental dengan pengujian di lingkungan air yang dikontrol secara laboratorium. Parameter yang diukur meliputi sensitivitas sensor terhadap perubahan tekanan suara dan respons frekuensi. Hasil penelitian menunjukkan bahwa ketebalan diafragma berpengaruh signifikan terhadap kinerja sensor. Diafragma dengan ketebalan 0,5 mm menunjukkan sensitivitas tertinggi dan respons frekuensi yang optimal. Sementara itu, diafragma dengan ketebalan 1 mm dan 2 mm menunjukkan penurunan sensitivitas dan respons yang kurang optimal. Kesimpulan dari penelitian ini adalah diafragma silicone rubber yang optimal untuk sensor deteksi suara bawah air berbasis serat optik SMS adalah ketebalan 0,5 mm, yang memberikan keseimbangan terbaik antara sensitivitas dan respons frekuensi.

Singlemode-multimode-singlemode (SMS) optical fiber sensors have been widely developed for various applications. Underwater acoustic sensing is an important application of optical fiber sensors because light and electromagnetic waves experience high attenuation and short propagation distances in water, whereas acoustic waves have lower attenuation and can propagate farther in turbid waters. This study aims to analyze the effect of varying silicone rubber diaphragm thickness on the performance of underwater sound detection sensors based on singlemode-multimode coreless-singlemode (SMS) optical fibers. SMS sensors are chosen for their high data transmission capability and good sensitivity to acoustic pressure changes. The silicone rubber diaphragm thicknesses tested are 0.5 mm, 1 mm, and 2 mm. The study employs experimental methods with tests conducted in a controlled laboratory water environment. The measured parameters include sensor sensitivity to sound pressure changes and frequency response. The results indicate that diaphragm thickness significantly affects sensor performance. A diaphragm thickness of 0.5 mm exhibits the highest sensitivity and optimal frequency response, while diaphragms with thicknesses of 1 mm and 2 mm show decreased sensitivity and less optimal response. The conclusion of this study is that the optimal silicone rubber diaphragm thickness for SMS-based underwater sound detection sensors is 0.5 mm, providing the best balance between sensitivity and frequency response.
