The Effect of Natural Preservatives from Jackfruit Wood Percentage Addition on Palm Oil Sap (Elaeis guuineesis Jacq.) During Storage

: Oil palm plantations continue to increase in Indonesia. Oil palm which is no longer productive will be replanted and replace with new seeds. Oil palm replanted still has the potential to produce oil palm sap. Oil palm sap is perishable so it is necessary to handle palm oil sap before entering a further production process, one of which is natural preservative from jackfruit wood. This study used a completely factorial randomized design with 2 factors, namely the concentration of jackfruit wood added (K): (3%, 6%, 9%, 12%) and storage time (T): (0 days, 1 day, 2 days, 3 days). The result showed that the best oil palm sap was from the treatment the percentage increase of 12% jackfruit wood and storage for 3 days.
