Abstract
Sweet orange peel (Citrus sinensis) is an organic waste that is quite abundant in both urban and rural areas. Orange peel waste is rich in secondary metabolite compounds that can be reprocessed into something useful. The content of limonene compounds in sweet orange peel is 91%. The high content of limonene compounds in sweet orange peel has the potential to be used as raw material for making essential oil. The length of soaking in the manufacture of sweet orange peel essential oil affects the yield produced. The method used to obtain essential oil uses maceration extraction with variations in the length of soaking, namely 4, 5, 6, 7 and 8 days using 90% ethanol solvent. The results showed that the highest yield was in the 5-day soaking period with a yield percentage of 36.90%. The density of essential oil produced was 0.80%. Organoleptic tests related to the color and odor of the essential oil produced are reddish yellow and have a distinctive smell of sweet orange.
Keywords : orange peel, soaking time, maceration, essential oil, yield.
