Abstract

Penelitian ini bertujuan untuk membuat alat ukur kadar gas karbon monoksida di udara yang hasilnya dapat di lihat di web secara real time dengan rentang pembacaan 0-100 ppm. Penelitian dilakukan di laboratorium elektronika, lantai 4 Gedung L Fakultas Teknik, Universitas Negeri Jakarta sejak Juli 2017 sampai Juli 2018. Penelitian ini dibuat menggunakan metode rekayasa teknik yang memiliki 4 langkah penelitian, yaitu analisis kebutuhan, perencanaan dan perancangan, pengembangan, pengujian dan perbaikan. Alat monitoring kadar gas karbon monoksida di udara via web terbagi menjadi 3 subsistem utama, yaitu : input, proses, dan output. Subsistem input terdiri dari sensor MQ-7 yang digunakan untuk mendeteksi gas CO dan menghasilkan gelombang listrik yang akan di proses oleh subsistem proses yakni Node Mcu. Pada subsistem proses dihasilkan data berupa sinyal ADC yang di konversi menjadi tegangan yang menjadi acuan untuk menggerakkan subsistem output yang terdiri dari LCD display, Buzzer, dan web. Subsistem output akan menampilkan data hasil monitoring kadar gas CO dalam satuan ppm. Selain itu buzzer akan berbunyi apabila hasil pembacaan gas CO sudah melebihi batas 80 ppm. Penelitian ini menghasilkan modul sensor gas CO MQ 7 yang sudah terkalibrasi dengan menggunakan formula pengali y = 114,54 x-1,683yang didapat dengan menggunakan persamaan regresi (trendline). Kalibrasi CO menggunakan kadar gas CO 100 ppm menunjukkan nilai error sebesar 3,11 * This study aims to create a device that measures carbon monoxide gas content in the air, the results obtained can be viewed on a web in real time with a reading range of 0-100 ppm. The research was conducted in electronics laboratory, 4th floor of Building L Faculty of Engineering, Jakarta State University from July 2017 until July 2018. The research method used is engineering method with development model through 4 steps, namely requirement analysis, planning and design, development, testing, and improvement. Carbon monoxide gas monitoring device via web is divided into 3 main subsystems, namely: input, process, and output. The input subsystem consists of MQ-7 sensor, which detects CO gas and generates electrical waves which will then be processed by the process subsystem, ie Node Mcu. In the process subsystem, data generated in the form of ADC signal is converted into a voltage that initiates to drive the output subsystem consisting of LCD display, Buzzer, and the web. The output subsystem will display the monitoring data of the CO gas content in ppm. In addition, the buzzer will buzz when the result shows that the CO gas readings have exceeded the limit of 80 ppm. The results of research produce a MQ-7 sensor moduleIt has been calibrated using the formula formula y = 114,54 x-1,683 obtained regression (trendline) power.Calibration sensors use gas CO grading 100 ppm showed a value of 3,11
