<![CDATA[Essential oils are vegetable oils that give plants their distinctive aroma and contain essential ingredients. The purpose of this study was to determine the yield of essential oil of lemon peel and kaffir lime peel by extraction and distillation. The method used in distillation is simple distillation, and for extraction, it is maceration. The results showed that the water content of the lemon peel was 3.37%. For the kaffir lime peel, it was 2.72 % when compared to the Indonesian National Standard (SNI), which was not appropriate because the water content had a value of 7 - 14 %. The yield of essential oil obtained from the distillation of lemon peel was 2.29 % and kaffir lime peel 1.02 %. The yield of essential oil obtained from the extraction of lemon peel was 1.07%, and kaffir lime peel was 1.32%. The identification test of the distilled essential oil did not show any stains on the filter paper, which indicated that the result obtained was essential oil. In contrast, the identification test of the extracted essential oil showed the presence of stains on the filter paper, which indicated that the results obtained were not essential oils. To determine the quality of the essential oil produced by characterizing the refractive index, color, and odor tests. The results obtained show that the refractive index for the distillation of lemon peel is 1.3381, and for kaffir lime peel is 1.4698. The refractive index for the extraction of lemon peels is 1.3812, and kaffir lime peels is 1.369. When compared with SNI 8028-1:2014, it is generally not appropriate because it has not reached 1.507, except that the distillation of kaffir lime peels meets the requirements of SNI, while the color and smell are in accordance with SNI.]]>
