Analisis Pengaruh Suhu Terhadap Sensitivitas Sensor Pada Hidung Elektronik Untuk Kematangan Tbs (Tandan Buah Segar) Kelapa Sawit

---

Electronic noses have been developed for decades in many fields. Recently, electronic
nose has been used in agriculture to detect the ripeness of fruits because fruits also
produce volatile gas during ripening. Oil palm fresh fruit bunches (FFB) is the main
source of crude palm oil, its quality depends on the ripeness levels of oil palm FFB.
Therefore, electronic detections of oil palm FFB ripeness need to be developed. This
study was aimed to investigate the effect of temperature variation on the sensitivity of gas
sensors in an electronic nose designed for detecting the ripeness of oil palm FFB. The
electronic nose used in this study consisted of 4 sensors which were TGS 2611, TGS
2620, TGS 813 and TGS 822. Samples were peeled fruitlets of unripe, ripe and over ripe
oil palm FFB which were heated to temperatures of 30 oC, 45 oC, and 60 oC. Response of
each sensor was represented as a trapezoid area of voltage versus time for convenience.
The results showed that there was a significant difference in the output voltage of each
sensor when the sample temperatures were varied. Fruitlets of oil palm FFB heated at 60
oC resulted in higher trapezoid area which mean more volatile gas released. Based on
the resulted trapezoid area for each sensor. Sensors of TGS 2611 and TGS 822 are the
most sensitive which have higher trapezoid area for the variation of the temperatures.
Keywords: Electronic nose, gas sensor, ripeness, temperature, oil palm FFB
