Abstract

Processing palm fruit produces crude palm oil. Crude palm oil levels continue to increase during the fruit ripening process. The parameters used in determining the maturity criteria for palm oil harvest are color change and fruit breaking off from the bunch. Harvest quality is determined by the mature fraction. One of the problems that occurs in palm oil factories is the selection of palm fruit bunches (FFB), which are divided into three classes, namely unripe, ripe and over ripe. Selection of FFB is done manually, namely visually. The quality of palm oil is greatly influenced by the level of ripeness of the fruit at the time of harvest and post-harvest handling until the mill. This research aims to evaluate the use of variations in palm fruit maturity used in PKS which are related to yield and quality as well as oxidative stability and color. The research results showed that the variation in palm fruit maturity used resulted in the highest yield, namely 17% in P2. The quality of crude palm oil obtained from variations in fruit maturity shows different results, where the highest free fatty acid content of 2.57% is located in P2, namely a mixture of ripe and overripe fruit, while the highest water content is found in P2, namely 0.65 %. P3 has the highest impurity content of 0.68%. The oxidative stability and color obtained from using variations in fruit maturity that were heated for 24 hours decreased in value to red and yellow

Abstract

Acceleration of processing for fresh fruit bunches (FFB) is crucial to increase profitability and business opportunities for oil palm farmers. This research aims to evaluate the effect of using gamal (Gliricidia sepium) leaves and the duration of ripening on the percentage of FFB processing as well as the quality of crude palm oil. This study employed a factorial completely randomized design (CRD). The data were analyzed using ANOVA with Duncan’s Multiple Range Test at a significance level of 5%. The results of the analysis showed that the best treatment was S3T2 (40% gamal leaves, 20 h of ripening) with a natural processing percentage of 45.87% of the FFB weight and 60.34% of the total bunch weight. The use of gamal leaves and the duration of ripening significantly affected the quality parameters of the oil, especially the free fatty acid content. Treatment S1T1 (20% gamal leaves, 10 h of ripening) showed the best results with a free fatty acid value of 1.30%, meeting the quality standard (<5%). However, the moisture content still exceeded the quality standard (<0.5%), although treatment S3T2 yielded the best result at 0.63%. While, the impurity content quality met the quality standard (<0.5%), with the best value achieved by treatment S1T1 at 0.15%. Keywords: Bunch detachment, CPO quality, Ethylene, Gliricidia sepium, Ripening.
