Telah dilakukan penelitian tentang uji efektifitas minyak atsiri kulit buah jeruk manis (Citrus sinensis) sebagai tabir surya secara spektrofotometer UV-VIS. Penelitian ini bertujuan untuk menentukan potensi dari minyak atsiri kulit jeruk manis sebagai tabir surya yang ditentukan dengan nilai SPF, transmisi eritema dan transmisi pigmentasi. Minyak atsiri jeruk diperoleh dengan mengekstraksi kulit buah jeruk manis dengan metode pengepresan/pemerasan. Pengujian dilakukan menggunakan metode spektrofotometri UV pada panjang gelombang 290 – 400 nm terhadap konsentrasi minyak atsiri 20, 40, 60, 80, 100, dan 120 bpj. Hasil analisis menunjukkan bahwa minyak atsiri kulit buah jeruk manis (Citrus sinensis) mengabsorbsi sinar UV B hingga UV A dengan nilai SPF 1,094 hingga 1,380. Persen eritema dan pigmentasi pada konsentrasi 120 bpj berturut-turut adalah 66,98% dan 65,54%.

Kisar sweet orange is an endemic fruit and primary commodity from Kisar Island, Southwest Maluku Regency - Maluku Province. Currently, Kisar sweet orangeswere only consumed as fresh fruit during this time, partially processed into juice and the peels were discarded as wastes. Kisar sweet orange peels can be processed into essential oil to increase their economic value. The essential oil made from orange peels is highly preferable, especially for the middle to upper-class consumers, for health and air-freshening purposes.  This essential oil has a higher selling value. This research aims at isolating and identifying the chemical components and quality of essential oil made from Kisar sweet orange peels. This essential oil was isolated using a steam distillation method, and its chemical components were identified using GC-MS instruments.. The research results showed that the essential oil made from Kisar sweet orange peels dried with a cabinet dryer for two days utilizing the steam distillation method provides a yield of 0.53%, with its properties of specific gravity of 0.8457, refractive index of 1.4651 (20°C), acid number of 1.92, ester number of 8.05, and solubility in alcohol of 1:9. The main chemical component of the essential oil made from Kisar sweet orange peels detected by GC-MS is limonene (70.80%).

The research evaluates the extraction yield and antioxidant potentials of essential oil (EO) of sweet orange peels using pressurized liquid extraction (PLE), Soxhlet (Sox) and hydro distillation (HD). The extracts were investigated to find out the antioxidant properties using 2, 2 -diphenyl-1-picryl-hydrazyl (DPPH) and 2, 2 azino-bis (3-ethylbenzothiazoline-6-sulfonate) radical (ABTS•+). PLE and Soxhlet extracted essential oil showed additional polyphenol compounds and tannins using thin layerchromatogram (TLC) and chemical analyses,respectively. Hydrodistillation indicating a pure essential oil without identified tannins and polyphenols with the highest ABTS activity compared to other produced essential oils of PLE and Soxhlet. The major chemical constituents of the pure essential oil were identified by gas chromatography-mass spectrometry (GC-MS) and they include limonene (90.72%), myrcene (2.82%) and octanol acetate (1.24%). PLE had moderate high yield within short extraction time and the highest antioxidant (DPPH) and can be adjusted to individual materials to maximize the extraction yield and antioxidant property.

Introduction: The essential oils of orange peels had a considerable potential to be used as an antimicrobial agent. The aim of this present study is to analized chemical composition of Citrus spp. And the oral antimicrobial effect of Citrus spp. peels essential oils against Streptococcus mutans. Methods: Five orange peels species were used in this study consist of Lime (Citrus aurantifolia), Tangerine (Citrus nobilis), Sweet Orange (Citrus sinensis), Lemon (Citrus limon), and Kaffir Lime (Citrus hystrix). The isolated essential oils were analyzed using gas chromatography-mass spectroscopy (GC-MS). The Streptococcus mutans ATCC 25175 was employed against the antimicrobial effect of samples. Results: The extraction yields of hydrodistilled-essential oils from Tangerine, Kaffir Lime, Sweet Orange, Lemon, and Lime provided the extraction yields of 4.20, 2.26, 1.97, 1.74 and 0.83% yields, respectively. Major component essential oils of Citrus spp. was D-Limonene. The highest antimicrobial activity against S. mutans was Lime peel essential oil, followed by Lemon, Kaffir Lime, and Sweet Orange or Tangerine. All samples showed antimicrobial activity against S. mutans with the variation of antimicrobial action depending on the constituent of D-Limonene, β-Pinene, and α-terpineol. Conclusion: Major component chemical composition of essential oils of Citrus spp. was D-Limonene and antimicrobial activity by Lime peel essential oil due to its proportional amount of D-limonene and β-pinene and the highest antimicrobial activity.

One of factors that cause a bad quality of Boer Goat frozen semen is the growth of bacterial. This can be overcome by adding antibiotics such as streptomycin. To further suppress the growth of bacteria can be added other ingredients that contain antibacterials such as sweet orange essential oil. The purpose of this research is to know the percentage value of Membrane Integrity and Acrosome Integrity on Boer Goat frozen semen with addition sweet orange essential oil and streptomycin. The method used was experimental using Completely Randomized Design with 5 treatments and 5 replications. The treatment in this research is addition 0%, 0,25%; 0.5%; 0.75% and 1% sweet orange essential oil on tris yolk and streptomycin extender. The results showed the best treatment addition combination streptomycin and sweet orange essential oil to percentage Membrane Integrity and Acrosome Integrity is increase 1% sweet orange essential oil.Keywords: Boer Goat, essential oil, frozen semen, streptomycin, sweet orange.

AbstractThe purpose of this study was to know the quality of Boer liquid semen during storage by adding sweet orange essential oil and gentamicin into the tris yolkextender.The semenlongevity test was carried out by storing semen in a closed tube at room temperature and refrigerator, and evaluated motility and Viability every 3 hours at room temperature and 12 hours in refrigerator. The results showed that the characteristics of the liquid semen, with the addition of 1% of essential oils showed percentage of motility and Viability significantly higher than 0.5% and without the addition of essential oil, either stored at room temperature or in the refrigerator. This may be related to the content of essential oils of sweet orange peel containing flavonoids and antibacterials that are capable of maintaining liquid semen quality of Boer Goat.In addition, gentamicin contains antibacterials capable of suppressing the growth of bacteria which can damage and durabilitythe spermatozoa.Keywords: Boer Goat,Gentamicin, Liquid semen, Sweet orange
