Abstract

Telah dirancang pengembangan sistem pengukuran TSS (Total Suspended Solid) dalam air menggunakan sensor serat optik secara real time. Sistem sensor serat optik mengukur nilai TSS dalam air memanfaatkan perubahan tegangan keluaran yang dihasilkan oleh fotodetektor akibat perubahan nilai TSS air. Rancangan sistem terdiri dari sumber cahaya berupa LED merah, serat optik FD-620-10, fotodioda OPT101, penguat istrumentasi IC INA114, mikrokontroler Arduino UNO dan program LabView sebagai penampil. Serat optik sepanjang 18,5 cm dikupas claddingnya sepanjang 5 cm, dan dibersihkan menggunakan larutan aseton, selanjutnya digunakan sebagai probe sensor. Pengumpulan data dilakukan dengan membandingkan sistem yang dirancang dengan standar pengukuran menggunakan metode gravimetri. Data yang diperoleh melalui pengukuran dianalisis menggunakan teori kesalahan dan metode grafik. Rata-rata dari 10 data dalam 120 detik dengan metode gravimetri menghasilkan perbedaan maksimum 4 V/(mg/L). Tegangan keluaran sensor berbanding terbalik dengan nilai TSS dalam air. Kesalahan relatif rata-rata didapatkan 4,04%.
