Development of fruit battery sensor with charging method for oil palm fruit ripeness detection

The oil palm fresh fruit bunches (FFB) has different maturity grading according to MPOB guidelines. Throughout the transferring process of FFB to the mills, the reception process of the FFB might contain various type of gradings which could affect the quality of the oil production. The FFB harvest f...

Throughout the transferring process of FFB to the mills, the reception process of the FFB might contain various type of gradings which could affect the quality of the oil production. The FFB harvest from the oil plantation might be in low quality grading, immature or rotten when inspected during mills inspection. Since the FFB received at the mills might not be matured or ripen enough due to those several factors, human inspection using eyes could not measure the ripeness content that can give inaccurate grading of the FFB to be processed.

An oil palm fruit battery sensor is designed and fabricated with aluminium and copper electrodes to test on the oil palm fruits from the FFB. The fabrication of the sensor consisted of four different types namely single, dual, three and fourth-set terminal type.
