Analisa Hubungan Intensitas Fluoresensi Terhadap Tiga Tingkat Kematangan Buah Kelapa Sawit Menggunakan Metode Fluorescence Imaging

---

Fluorescence imaging has been developed and used as a potential nondestructive method for fruit and vegetable quality assessments. Grading oil palm fresh fruit bunches (FFBs) is a very important step to obtain good quality of crude oil palm for oil palm companies. Fluorescence imaging has not thoroughly been explored for FFB grading. This research was aimed to study the fluorescence intensities of loose oil palm fresh fruits and their relations to the ripeness levels of the fruits using a fluorescence imaging system. The system composed of a 650 nm diode laser, a monochrome CMOS camera, and a color filter. The color filter used was a magenta color due to excitation by red diode laser. The samples were loosed oil palm fresh fruits from Tenera variety named Tenera A (Marihat) and Tenera B (Lonsum) taken from the middle of oil palm fresh fruit bunches. The samples had three levels of ripeness, under ripe, ripe, and over ripe, each had 5 loose fruits. The ripeness categories were determined by an experienced harvester. The illuminated fruit images were recorded by the camera and the gray intensities were obtained using ImageJ software and compared for three ripeness conditions. The anthocyanin concentration of the mesocarp and exocarp layers of the Tenera A fruits were measured as comparison. The results showed that the fluorescence intensity of the highest in the fruit Tenera A. The results showed that the fluorescence intensity for the under ripe fruits is higher than for ripe and over ripe fruits. The average of fluorescence intensity Tenera A for the under ripe fruits is 45,80%, for the ripe fruits is 41,11% and for the over ripe fruits is 25,55%. Anthocyanin concentration decreases with ripeness level. The concentration of anthocyanins have a linear relationship to the intensity of fluorescence, higher fluorescence intensity possess higher concentration of anthocyanins.
