Bedbugs are harmful human blood-sucking ectoparasites. The disadvantages of a bedbug bite cause itching, redness bumps, secondary infections, and anemia in children. Bedbugs controller so far uses harmful chemical pesticides, but reappearance of bedbugs indicates less effective chemical pesticides, and becomes a serious problem. So it needs safer controller for human health. This study aims to analyze the d-Limonene activity of orange peel (Citrus sinensis L.) in controlling the bedbug infestation (Cimex cimicidae). The study was conducted through 5 stages: d-Limonene isolation, GC-MS characterization, bioassay Y test d-Limonene nanoparticles, SEM characterization, and d-Limonene activity test on bedbug. The results showed that the essential oil of orange peel contained the main compounds as d-Limonene (90.018%), 1,6-Octadien-3-ol, 3,7-dimethyl- (3,017%), β-Myrcene (2.071%), Octanal (0.349%), 1-Octanol (0.589%), 1R-α-Pinene (0.688%), 6-Octen-1-ol, 3,7-dimethyl- (0.667%), 3-Cyclohexene-1- methanol, α, α, 4-trimethyl-, (S) - (1.453%), and Bicyclo [3.1.1] heptane, 6.6-dimethyl-2-methylene-, (1S) - (1.147%). The Bioassay Y test shows that d-Limonene was both repellent and fumigant, d-Limonene nanoparticles had uneven and irregular surface morphology, and in the flea activity test showed more than 50% bedbugs death. These research concluded that d-Limonene compounds from sweet orange peel had activity to control the bedbugs.

<pre>Sweet orange peel is a waste. There is a high economic valued chemical compound of essential oil called limonene which has a distinctive fresh aroma.. Essential oil of Limonene  was extracted from orange peel then will be applied as aromatherapy candles. The taking of essential oils is using distillation of liquid vapor for 3 hours. After that, the essential oil is added to aromatherapy wax and stearic acid. The volume of essential oil extracted from distillation in this study is 2,3 mL with weight 1.957 grams from 200 grams of orange peel. The addition of essential oil is 3 mL for sample 1 and 5 mL for sample 2.. The aromatherapy candles had tested for flame duration and product acceptance in the community. The result showed that the higher the content of Essential oil of Limonene  the longer the flame duration and the higher the acceptance in the community. </pre><p> </p><p><strong>Keyword</strong> : sweet orange peel, essential oil of Limonene, extraction, distillation, aromatherapy candle,</p><p> </p>

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

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%.

Supercritical Carbon

Limonene constitutes 98% of the essential oil obtained from orange peel. Besides being used as fragrances and flavours in the food, perfume and cosmetic industries, limonene is also a good degreasing agent. Supercritical carbon dioxide is an excellent solvent for non-polar compound like limonene but poor solvent for polar compound like α-terpineol. Common practice in supercritical fluid extraction is to change the polarity of supercritical carbon dioxide by employing polar modifiers to increase its solvating power towards polar analytes. Base on this, in the attempt to extract more limonene in orange essential oil, less polar modifiers were added instead. In this study, effects of adding modifiers with different polarity on extraction of aroma compounds (limonene, linalool and α-terpineol) from Citrus Sinensis L. Osbeck or sweet orange peel were investigated. Supercritical extraction was carried out at defined pressure and temperature for duration of 45 minutes. Concentration of aroma compounds extracted was analysed using GC-MS. The optimum conditions for extraction were observed at 318K and 12MPa. The concentrations of limonene increased significantly by the addition of methanol and slightly with n-heptane. It was also found that n-heptane is effective on supercritical CO2 extractions of linalool and α-terpineol.
