Abstract

Exhaust emissions generated by motor vehicles are increasing as the number of motor vehicles
increases. Carbon monoxide (CO) and Hydro Carbon (HC) is harmful substance contained in exhaust
emissions. This study aims to make emission test (prototype) to measure CO and HC levels on exhaust
emissions. This type of research is an experimental research with the waterfall model design method.
Arduino-based emission test (prototype) with working system of CO and HC concentration on emission
will be read by MQ2 and MQ9 sensor connected with Arduino and displayed on lcd screen in digital
number using C language program. Further data on the prototype is taken and compared with the data
on the gas analyzer using the T Test method. The results of testing the CO and HC levels on emission
test equipment (prototype) with the results of testing using a gas analyzer still showed a significant
difference with the significance value of CO level readings of 0.319 and HC levels of 0.896.
