Judul: Potensi Minyak Atsiri Temu Kunci (Kaempferia pandurata) dan Komponennya sebagai Pelangsing Aromaterapi
Abstrak: Kaempferia pandurata is an Indonesian aromatic plant containing essential oil. The objectives of the research were to separate constituents of K. pandurata oil and to evaluate the active components as slimming aromatherapy. The essential oil was collected by steam distillation method from the rhizomes, giving 0.5% (v/w) yield. The distillate was fractionated using column chromatography resulting 7 fractions. Based on gas chromatography-spectrometer mass analysis, the main component in essential oil of was o-cymene, and the major component in fraction 1 was limonene. Fraction 1, camphor, and the essential oil were analyzed for their activities as slimming aromatherapy by using adult male Sprague Dawley rats. Inhalation of camphor and the essential oil showed a trend of higher response on the body weight compared to the positive control (high cholesterol diet). Animals treated with fraction 1 inhalation showed the lowest body weight gain response, 47% (w/w). Therefore, based on these results, fraction 1 do have potency as slimming aromatherapy agent.

Abstrak: Nutmeg is a spice plant native of Indonesia that contains essential oils, including myristicin as the main psychoactive compound. In this study, myristicin was fractionated from nutmeg essential oil and analyzed for its potency as slimming aromatherapy with in vivo assay. Nutmeg essential oil was fractionated by using column chromatography resulting fraction 5 (F5) having similar chromatogram pattern to myristicin standard. Nutmeg essential oil, F5, and α- pinene were then analyzed by gas chromatograph-mass spectrometer, and the slimming aromatherapy potencies were studied on white adult male Sprague- Dawley rats. Inhalation of nutmeg essential oil, F5, and α-pinene for 30 days showed lower percentage of body weight gain compared with positive control group (high fat and cholesterol feed) although the differences were not significant.

Judul: Cycle Hamilton pada Graf Lengkap, Graf Regular, dan Graf 2-Connected 4-Regular Berorder Kurang dari Sepuluh
Abstrak: Suatu graf disebut graf Hamilton apabila graf tersebut memuat cycle Hamilton, yaitu cycle yang melewati setiap vertex tepat satu kali. Menentukan keberadaan cycle Hamilton pada suatu graf dapat menggunakan syarat cukup yang berupa teorema-teorema yang telah diperkenalkan sejak tahun 1950-an. Beberapa syarat cukup yang dibahas dalam karya ilmiah ini adalah syarat cukup yang berhubungan dengan graf lengkap dan graf regular. Suatu graf lengkap berorder 𝑛������ ≥ 3 dan graf r-regular berorder 𝑛������ ≤ 2𝑟������ + 1 merupakan graf Hamilton, Karena kedua graf tersebut memuat cycle Hamilton. Selanjutnya, syarat cukup tersebut digunakan untuk menentukan keberadaan cycle Hamilton pada graf 2-connected 4- regular berorder kurang dari 10.
