Based on the provisions of SNI 7554: 2010, it explains
that the tool used in measuring fuel consumption is able to measure the
quantity consumed with ± 2% accuracy, and if you use a valve system for rapid
displacement from the normal fuel usage line to the measurement system, the
displacement is it cannot be longer than 0.2 seconds. The fuel consumption
measurement tool actually already exists, but the working system in calculating
the fuel consumption from this is done using visual sensing parameters, namely
conditioning the motor rpm in a certain position and calculating how much fuel
volume is reduced in units of time using a stopwatch. This method causes the
reading process to be inaccurate and still depends on the accuracy of the human
being itself which is influenced by the factors of concentration, fatigue,
reading response and others. Therefore, an Automatic Fuel Meter is designed to
be a solution to these problems. The purpose of this research is to design and
create an automatic control system that can calculate fuel consumption on the
trainer using a microcontroller with the available trainer mechanics.
This design using
the type of research (R&D) Research and Development or experiment-based
development research. This case the researcher designed the control system on
the Automatic Fuel Meter. In implementation, the researcher carried out several
stages, namely; determine research targets, determine the concept of
completion, design control systems, build control systems and test the
performance of the control system. The control system performance data is
collected in several stages, namely infrared sensor testing, Arduino software
testing, and precision testing.
The result of this research is that
the Automatic Fuel Meter uses the Arduino Nano controller as the controller,
the infrared sensor is used as a timer or timer for fuel consumption. The
algorithm of the work carried out in calculating fuel consumption has 3 stages,
namely the filling stage, the reading stage, and the data calculation stage.
The Automatic Fuel Meter can calculate fuel consumption with the precision
value sought from the known standard deviation of 0.194366778. So that the
percentage value of the variation coefficient is obtained at 1.7057198596% ~
1.7%. The response time from the infrared sensor takes 0.202083 seconds in the
test on pertalite fuel and 0.200521 seconds in the Pertamax fuel. Based on
these results, it shows that the value is appropriate based on the information
data from SNI 7554: 2010 which states that the tool used in measuring fuel
consumption is able to measure the quantity consumed with an accuracy of 2%,
and if using a valve system for fast moving from the line of use. normal fuel
to the measurement system the displacement should not be longer than 0.2
seconds.
