Palm oil yield potency on different level of ripening and storage time based on fruits percentage and fresh fruit bunches

This study aimed at assessing the oil yield potency of palm oil, based on fruits percentage (% fruit) and percentage of fresh fruit bunches (% FFB) due to the storage at different ripeness (under-ripe, ripe, over-ripe, and loose fruit from bunches) from fresh fruit bunches (FFB) originating from plantations in Ungaran, Central Java, Indonesia. A completely randomized design (CRD) with 2 factors on the ripening and the storage levels of FFB was used. The parameters observed at the initial stage were oil contents as the basis for calculation, and the yield potencies were then analyzed on the basis of % fruits and % FFB. The data obtained were analyzed by ANOVA and continued with Duncan test alpha = 0.05 using SPSS version 25. Results showed that both of the ripening level of palm fruit bunches and storage time significantly (alpha = 0.05) affected the yield potency on the basis of % fruit or % FFB, the potential yield value was based on the percentage of fruit higher than the yield potential based on the percentage of FFB. The highest yield potential based on the percentage of fruit found on ripe FFB with a storage time of 12 hours and the lowest on under-ripe FFB with a storage time of 60 hours. While the highest potential yield based on the percentage of FFB was found on ripe FFB with a storage time of 12 hours and the lowest on under-ripe FFB with a storage time of 60 hours.
