Abstract

Emisi gas buang yang dihasilkan oleh mesin diesel lebih tinggi dibandingkan dengan jenis motor pembakran dalam lain. Hal ini dapat membahayakan kehidupan mahkluk hidup dan merusak kualitas udara. Emisi sebuah mesin harus memenuhi standar tertentu dan juga sebagai refrensi perawatan mesin tersebut sehingga dibutuhkan alat monitoring emisi tersebut. Oleh karena itu, penulis memberikan alternatif alat monitoring emisi Partikulat (HC, PM, VOC) dan Suhu gas buang berbasis mikrokontroller. Perancangan hardware dan software alat monitoring emisi partikulat (HC,PM, VOC) dan Suhu Gas buang ini menggunakan mikrokontroller Arduino untuk mendapatkandan mengolah sinyal analog dan digital. Sinyal-sinyal inputan tersebut berasal dari sensor MQ-2, MS1100, Nova PM Sensor, dan Thermocouple K-Type MAX6675. Masing – masing sensor sebagai pengukur Hidrokarbon, Volatile Organic Compound (VOC), Particulate Matter 2,5/10 micron, dan Suhu. Pengukuran alat monitoring ini ditampilkan pada display LCD 16x4 dan Microsoft Excel sebagai data logger serta menampilkan grafik pembacaannya. Kemudian dibuat aplikasi kalibrasi dengan menggunakan program Visual Basic untuk memastikan hasil pembacaan sesuai dengan konsentrasi yang ada. Hasil validasi dan kalibrasi menunjukkan tingkat kesalahan masing-masing sensor antara lain sensor suhu sebesar 2,25 % pada suhu ruangan dan 3,35% pada suhu gas buang, dan Gas Hidrokarbon sebesar 5,58%. Setiap sensor mempunyai karakteristik sensitivitas dan respon time masing masing antara lain ; Sensor Suhu thermocouple k-type max6675 dengan sensitivitas dan respon time pada detik ke 56 – 96. Untuk sensor Hidrocarbon (HC) MQ-2 dengan sensitivitas dan respon time pada detik ke 16 -88. Kemudian untuk sensor Volatile Organic Compound (VOC) MS1100 dengan sensitivitas dan respon time pada detik ke 48 - 88 ; dan Sensor Nova PM (PM2,5 dan PM10) dengan sensitivitas dan respon time pada detik ke 16 - 178. ================================================================================================ Exhaust gas emissions produced by diesel engines are higher than other types of internal combustion engine. This can endanger the lives of living things and damage air quality. The emissions of a machine must meet certain standards and also as a reference for the maintenance of the engine so that the emission monitoring tool is needed. Therefore, the authors provide an alternative monitoring tool for Particulate emissions (HC, PM, VOC) and exhaust gas temperature based on microcontrollers. The design of hardware and software for monitoring particulate emissions (HC, PM, VOC) and temperature of exhaust gas uses an Arduino microcontroller to get and process analog and digital signals. The input signals come from the MQ-2 sensor, MS1100, Nova PM Sensor, and K-Type MAX6675 Thermocouple. Each sensor is a measure of Hydrocarbons, Volatile Organic Compound (VOC), Particulate Matter 2.5 / 10 microns, and Temperature. The measurement of the monitoring tool is displayed on LCD 16x4 and Microsoft Excel as a data logger and displays the reading graph. Then a calibration application is made using the Visual Basic program to ensure the reading results are in accordance with the available concentration. Validation and calibration results show the error rate of each sensor, including temperature sensors of 2.25% at room temperature and 3.35% at exhaust gas temperature, and Hydrocarbon Gas at 5.58% Each sensor has its own sensitivity and response time characteristics, among others; Max6675 thermocouple k-type Temperature Sensor with sensitivity and response time at 56 - 96 seconds. For Hydrocarbon (HC) MQ-2 sensors with sensitivity and response time at 16 -88 seconds. Then for the Volatile Organic Compound (VOC) MS1100 sensor with sensitivity and response time at 48-88 seconds; and Nova PM Sensors (PM2.5 and PM10) with sensitivity and response time at 16 - 178 seconds.
