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.

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%.

The volatile oils extracted from leaves of eight cultivars of Citrus sinensis (L) Osbeck were comprehensively analysed by a combination of GC and GC-MS. Fifty four constituents accounting for 82.3-98.2% were identified. Sabinene (20.9-49.1%), δ-3-carene (0.3-14.3%), ( E)-β-ocimene (4.4-12.6%), linalool (3.7-11.1%) and terpinen-4-ol (1.7-12.5%) were the major constituents that are common to all the volatile oils. In addition, a cluster analysis was carried out and indicated at least four different chemotypes for the C. sinensis cultivars.
