ABSTRACT
Nowadays , increasingly sophisticated technology in the field of sensors is needed
in order to determine the quality of agricultural products in a modern way, which
is usually done using five senses method. The electronic nose olfactory system is
an alternative way to obtain high quality CPO. This study aims to design an
olfactory system based on the MQ type gas sensor CMOS to detect the maturity
level of oil palm FFB. This olfactory system consists of 8 sensors MQ2, MQ3,
MQ4, MQ5, MQ6, MQ8, MQ135 and MQ136. Python based program is used as
data acquisition processing data. The results showed a significant difference in the
output voltage of each sensor in the three maturity categories, namely under ripe,
ripe and over ripe. The resulting voltage is converted into a trapezoidal area to
obtain one value so as not to fluctuate. The peak area of the trapezoid is higher in
over ripe and ripe FFB compared to that for under ripe FFB. The yield of the
trapezoid area is directly proportional to the level of ripeness because the higher
the area obtained as the maturity level increases. The highest area value is
141,7329 in the over ripe fraction and the lowest area of 108,981 for the under
ripe fraction. The hardness of FFB was measured using a penetrometer as a nondestructive
method to determine the ripeness level as comparative data. The
results of the oil palm fruit hardness test are inversely related to the ripeness level.
The value of the hardness level exhibits smaller as the process of oil palm fruit
maturity increases. This is influenced by the oil content in the palm which
increases with the ripening process, in which the more ripe the fruits the softer
they become.
Keywords: Electronic nose, gas sensor CMOS, Python, ripeness,hardness, oil
palm FFB.
