Abstract
ABSTRAK. Telah dirancang dan dibuat sebuah alat pengukur kadar alkohol (C2H5OH) pada produk pangan berbasis mikrokontroler ATMega 8535 menggunakan sensor gas Tgs 2620. Alat ukur ini dikalibrasi menggunakan alkoholmeter. Data yang telah diolah hasilnya ditampilkan oleh LCD 16 x 2. Proses pengambilan, pengolahan, dan komunikasi data diatur oleh program pada mikrokontroler ATMega 8535 dengan bahasa . pemrograman BASCOM. Pengukuran dilakukan pada sampel yang berupa campuran antara cairan Alkohol dan akuades dengan jumlah 100 ml yang diuapkan. Pengukuran dilakukan sebanyak 5 kali pengulangan. Kalibrasi alat dilakukan dengan cara mengambil data tegangan sensor dari cairan alkohol yang telah di encerkan. Alat ini memiliki range pengukuran 0% sampai 97% dengan kesalahan 4,9%. Sampel produk pangan yang akan di gunakan dalam pengaplikasian alat ini adalah Bintang Bir Pilsanier Zero, Vodka Mixmax, Anker Beer, Pepsi Twist, Kratindaeng Energy Drink, Yogurt, Kecap, Permen Mints, Saos, Calpico Soda, Maya Sarden, Dan Tapai. Kata kunci: alkohol, sensor gas TGS 2620, mikrokontroler ABSTRACT. It has been designed and fabricated a gauge levels of alcohol (C2H5OH) on microcontroller ATMega 8535 based food products using gas sensor TGS 2620. Alcohol content measuring instrument has calibrated using Alkoholmeter. The Data from the sensors has processed by microcontroller which results displayed by the LCD 16 x 2. The process of collecting, processing, and communication of data is set by the microcontroller ATMega 8535 program with BASCOM programming language. Measurements were made on samples in the form of a liquid mixture of alcohol and distilled water with 100 ml evaporated. Measurements were performed in 5 repetitions. Calibration of the instrument that by taking the data from the sensor voltage fluids that have been in dilute alcohol. This tool has a measurement range of 0% to 97% with a 4.9% error. As a food product samples that will be used in the application of this tool is Bintang Bir Pilsanier Zero, Vodka Mixmax, Anker Beer, Pepsi Twist, Kratindaeng Energy Drink, Yogurt, Kecap, Permen Mints, Saos, Calpico Soda, Maya Sarden, Dan Tapai. Keywords: Alcohol, Gas Sensor TGS 2620, Microcotroler
