Abstract

Telah dilakukan penelitian dan perancangan alat ukur kadar alkohol dengan menggunakan sensor MQ-3 berbasis mikrokontroler AT89S51 menggunakan bahasa pemograman Bahasa C. Sensor alkohol mendeteksi keberadaan gas alkohol. Kadar alkohol pada cairan diukur dengan sensor gas alkohol MQ-3. Tegangan keluaran dari sensor dikonversi oleh ADC 0804 kemudian diolah mikrokontroler untuk diproses. Kadar alakohol didapatkan hanya dalam bentuk data digital dari ADC 0804 dan belum dalam bentuk tampilan LCD. Hal ini kemungkinan disebabkan oleh kesalahan perakitan komponen LCD. Dari hasil rancang bangun alat ukur kadar alkohol dalam cairan ini didapatkan hasil pengujian yang menunjukkan adanya kenaikan nilai tegangan keluaran sensor saat sensor mendeteksi adanya alkohol. Nilai kesalahan pengukuran yang terjadi pada alat ini adalah sebesar 3,25%.
