Description:

Telah dibuat suatu sistem pengukuran indeks bias cairan berdasarkan perubahan intensitas cahaya yang terdeteksi pada fiber optik. Permukaan fiber optik dimodifikasi sehingga mampu mendeteksi perubahan yang dialami selama proses perlakuan. Sistem ini menggunakan sumber cahaya berupa laser He – Ne sebagai transmiter, fotodioda sebagai receiver, dan ADC sebagai konversi data analog ke data digital serta cairan yang digunakan adalah Aquades, Minyak Tanah, Solar, dan Bensin. Sumber cahaya dimasukkan ke dalam pangkal fiber optik dan dideteksi keluarannya pada ujung fiber optik oleh fotodioda. Suatu ADC dengan resolusi 8 bit diatur dengan perangkat lunak untuk mengukur tegangan fotodioda yang ditimbulkan akibat intensitas sinar laser. Tegangan fotodioda dibaca oleh ADC dan ditampilkan dalam bentuk nilai indeks bias dalam Personal Computer (PC). Dari percobaan yang telah dilakukan diperoleh hasil, nilai indeks bias cairan adalah Aquades sebesar 1,3318; Minyak tanah sebesar 1,449; Solar sebesar 1,4671; dan Bensin sebesar 1,422. Besarnya standart deviasi dari sistem sensor yang dibuat adalah 0,002


Alt. Description

Measurement systems of liquids refraction index has been made based on light intensity changes detecting by an optical fiber. The surface of the optical fiber was modifying to detect any changes as long as measuring process. This system using He-Ne laser as a transmitter, photodiode as a receiver, and ADC as a analog data converter into digital data and also use Aquades, Kerosene, Solar, and Gasoline as the utilized liquid. The light source was radiated into the optical fiber and output detected by photodiode on the other end of the optical fiber. An 8-bit resolution ADC arranged with software to measure photodiode voltage excited by laser intensity. Photodiode voltage was reading by ADC and displayed in form of refraction index on the PC. Result of experiments produce the refraction index of Aquades 1,3318; Kerosene 1,449; Solar 1,4671 and Gasoline 1,422.The deviation standard of the manufactured is 0,002.
