Identifying Nipah Fruit Extract with Cycle Variations Using a Methanol Solvent

Abstract

Indonesia has many sources of vegetable oil that can be used as a renewable energy source. One of these sources that has great potential to be developed is palm fruit (Nypa Fruticans Wurmb). Nipah fruit is one of the raw materials used in this study, using the extraction method and methanol as the solvent. The research was conducted with various cycles variations of 5, 6, 7, 8 and 9. The extracted oil had a fragrant odor, a clear yellow color and was volatile. Tests were then carried out, including percentage yield, pH, free fatty acid (FFA), iodine number and density. From the test results, it was found that the average yield of palm fruit oil was nine cycles reaching 1.2%, where the highest percentage yield was found in the 35-gram sample, the pH number for five samples showed the number six, percentage FFA of palm fruit oil on average was 0.6%, the iodine number of fruit oil Nipah was an average of 0.18 and the specific gravity of Nipah fruit oil on average was 0.76 gram/ml.
