| Abstract | Ministry of Agriculture and Cooperatives policy for oil palm looking forward to announce a regulation for oil palm dealing to be obligated on percentage of oil. However, there is currently no accurate, fast and standardized instrument for measuring percentage of oil in palm. Consideration of all oil palm bunch characteristics consists of oil and non-oil portions and irregular maturity of oil palm bunch had to be concluded in design and development of palm oil percentage meter. The objective of this report was study of palm oil percentage measurement for oil palm bunch using electric probe prototype. Appropriate probe was cylindrical type cup and apposite electrical property was capacitance. Oil palm fibrous husk or mesocarp in this developed measurement methods were sliced and filled in a modified cylinder probe. Prototype of palm oil percentage meter for oil palm bunch was developed from relationship between moisture content of palm fibrous husk and capacitance value of sliced palm fibrous husk from modified cylindrical probe and relationship between moisture content of palm fibrous husk and oil percentage per oil palm bunch. Output signals of the prototype circuit in terms of peak-peak output voltage were achieved from oscilloscope. The prototype must change the resistance value (R) with a 3-selector switch.Resistivity value (R) was used as 613 k?, 100 k? and 10 k? for ripe, semi-ripe and unripe palms, respectively. The prototype will be further developed in terms of PCB circuit boards to make it easy to use, fast, accurate, repeatable, re product and reproductivity |
