    Abstract
    Telah dilakukan penelitian rancang bangun alat ukur kadar alkohol menggunakan sensor MQ-3 berbasis arduino uno. Tujuan nya adalah pembuatan alat ukur kadar alkohol. Alat ukur yang telah dibuat terdiri dari sensor MQ-3, Arduino uno, LCD 16 x 2, konektor USB dengan sumber tegangan 5V dan komponen lainnya. Sampel kadar alkohol telah dibuat dengan variasi kadar. Saat ini kekawatiran masyarakat dengan minuman keras yang sudah gampang ditemukan diwarung warung dengan harga yang relatif murah, menyebabkan banyaknya terjadi kecelakaan, perkelahian, pembunuhan, perzinahan, jauh dari norma-norma akhlak dan timbul keberanian untuk melakukan tindakan negatif. Hal ini merupakan prioritas utama diperlukanya suatu tes alkohol sederhana yang dapat mengukur kadar alkohol. Sehingga dalam tugas akhir ini dirancang dan direalisasikan alat untuk mengukur kadar alkohol menggunakan snsor MQ3. Proses kerja dari alat pengukur kadar alkohol melalui gas yang dikeluarkan Alkohol dan merubah datatersebut ke analog ke digital kemudian arduino un mengelolah input yang didapat dari sensor MQ3 dan ditampilkan melalui LCD.
     
    The measuring instrument the level of alcohol using gas gas sensor MQ-3 based microkontroller Arduino Uno had been research. The purpose to product measuring instrument the level of alcohol beverages and text measuring instrument the level of alcohol beverages. The measuring instrument had made of gas sensor MQ-3, Arduino Uno, LCD 16x2, USB connector with voltage input 5V and other components. The level of alcohol sample had made of level variations. The current public concerns with the liquor that has been easily found in a stall stall at relatively low prices, causing many accidents, fights, murders, adulteries, far from the norms of morality and raised the courage to undertake negative actions. Thisis a major priority of alcohol required a simple test that can measure the level of alcohol in the human body. So in this thesis designed and realized a tool to measure the alcohol content through the use of sensors MQ3 .The working process ofthe measuring device through blowing breath alcohol content that is changing analog to digital data then microcontroller arduino uno manage the input obtained from the sensor MQ3 and displayed LCD.
