The oil palm plantation industry is one of Indonesia leading sectors in agriculture, every year tends to continue to increase. The level of repeness of palm oil is an important factor in determining the quality of Cruide Palm Oil (CPO). If the harvested fruit is too raw or too ripe it will be affected by the quality of CPO. The process of sorting and determining the quality of FFB (Fresh Fruit …
The level of oil palm maturity is an important factor in determining the quality of Cruide Palm Oil (CPO). If the fruit is harvested too raw or too ripe it will affect the quality of the CPO. Good CPO quality is determined from the content of free fatty acid, which is less than 5 %. The sorting and grading process is generally done traditionally and manually. This method is subjective and slow…
