Abstract

Sensor ethanol berbasis serat optik plastik menawarkan solusi murah dan fleksibel untuk mendeteksi kadar ethanol. Namun, suhu lingkungan dapat mengurangi akurasi sensor, yang mengubah indeks bias dan sudut sinar, menyebabkan kehilangan daya dalam sensor. Oleh karena itu, diperlukan lapisan pelindung untuk meningkatkan kinerjanya. Dalam penelitian ini, penggunaan serat optik plastik (POF) dengan panjang taper 5 cm dan sumber cahaya LED dengan panjang gelombang 650 nm diuji dalam rentang suhu 25°C–40°C. Proses fabrikasi dilakukan dengan memberikan lapisan PVA (polyvinylalcohol) dan zirkon dari konsentrasi PVA 100% - zirkon 0%, PVA 99,5% - zirkon 0.5%, PVA 99%-zirkon 1%. Hasil penelitian menunjukkan bahwa penambahan lapisan PVA-Zirkon dapat meningkatkan akurasi pengukuran kadar ethanol. Lapisan PVA-Zirkon berfungsi sebagai pelindung terhadap fluktuasi suhu dan, yang berkontribusi pada stabilitas indeks bias dan meningkatkan daya keluaran sensor, dimana linearitas tertinggi dicapai pada coating PVA 99%-zirkon 1% dikonsentrasi 60% sebesar 0.999 dan sensitivitas tertinggi juga terjadi pada coating ini yaitu sebesar 0,262 dBm/oC

Plastic fiber optic based ethanol sensors offer a cheap and flexible solution for detecting ethanol levels. However, ambient temperature can reduce sensor accuracy, which changes the refractive index and beam angle, causing power loss in the sensor. Therefore, a protective layer is needed to improve its performance. In this research, the use of plastic optical fiber (POF) with a taper length of 5 cm and an LED light source with a wavelength of 650 nm was tested in the temperature range of 25°C–40°C. The fabrication process is carried out by providing a layer of PVA (polyvinylalcohol) and zircon from a concentration of 100% PVA - 0% zircon, 99.5% PVA - 0.5% zircon, 99% PVA-1% zircon. The research results show that the addition of the PVA-Zircon layer can increase the accuracy of measuring ethanol levels. The PVA-Zircon layer functions as a protector against temperature fluctuations and, which contributes to the stability of the refractive index and increases the output power of the sensor, where the highest linearity is achieved in the 99% PVA-1% zircon coating concentrated 60% at 0.999 and the highest sensitivity also occurs in this coating. namely 0.262 dBm/oC
