Abstract

Telah dirancang sistem sensor serat optik untuk mengukur tingkat kekeruhan air dengan model U-system. Rancangan sistem terdiri dari pemancar berupa LED merah (660 nm), serat optik FD 620 10, fotodetektor OPT101, mikrokontroler ATMEGA32 untuk memproses masukan detektor, dan LCD untuk penampil. Serat optik sepanjang 30 cm dikupas claddingnya pada bagian tengahnya sepanjang 5 cm. Pengumpulan data dilakukan dengan membandingkan hasil keluaran dari detektor dari beberapa variasi sudut pembengkokan serat optik terhadap larutan yang telah diketahui nilai kekeruhannya. Pemberian variasi sudut pembengkokan memberikan perbedaan sensitivitas pada pengukuran. Dengan menganalisa nilai keluaran sensor akibat pembengkokan, didapatkan besarnya rugi daya yang dialami sensor sebanding dengan besarnya sudut pembengkokan yang diberikan. Semakin besar sudut yang diberikan maka akan semakin tinggi sensitivitas pengukuran, namun terdapat suatu keadaan dimana apabila sudut diperbesar lagi maka sensitivitasnya berkurang.
