Judul: Pengaruh Minyak Serai Wangi (Cymbopogon Nardus L. Rendle) Terhadap Pertumbuhan Microsporum Canis Secara In Vitro
Abstrak: Dermatofitosis merupakan salah satu penyakit kulit yang paling umum menyerang manusia, hewan kesayangan, dan ternak. Penyakit ini secara luas menyebar ke seluruh dunia dengan berbagai tingkat keparahan. Dermatofitosis disebabkan oleh tiga genus diantaranya Epidermophyton, Trichophyton, dan Microsporum. Penularan sesama hewan, tingginya biaya pengobatan, sulitnya pengendalian penyakit, dan dampak yang diberikan kepada masyarakat menjelaskan pentingnya penyakit ini. Pengembangan pengobatan antifungal yang lebih efektif dan tidak terlalu bersifat toksik sangat diperlukan. Tujuan dari penelitian ini untuk mempelajari pengaruh minyak serai wangi terhadap infeksi dermatofita yang disebabkan Microsporum canis. Pengujian kualitatif dilakukan dengan menggunakan metode difusi cakram. Uji daya hambat minyak serai wangi terhadap pertumbuhan koloni Microsporum canis yang dilakukan dengan tiga kali ulangan menghasilkan diameter zona hambat berturut-turut sebesar 15.67 mm, 16.67 mm, dan 13.33 mm.

Judul: Aktivitas Beberapa Antimikotik terhadap Microsporum gypseum sebagai Penyebab Dermatofitosis pada Kuda
Abstrak: Dermatophytosis is a superficial cutaneous fungal infection that attacks the keratin layer of the skin caused by a group of fungi known as dermatophytes. Microsporum gypseum is a geophilic dermatophyte that suspected to cause this infection in horses. In this research, isolation and identification of sample from the horse that was suspected to be infected with dermatophytosis caused by M.gypseum was done. As an effort to treat dermatophytosis, antimycotics are widely used. The aim of this study is to be able to diagnose accurately the cause of dermatophytosis in horses and the agent that causes it.The procedure of this research included rapid isolation and identification, using KOH 10%, isolation onto DSA media and identification using Riddle’s slide culture method. The antimycotic test was done using disk diffusion assay method and the antimycotics used in the test were ketoconazole, amphotericine, voriconazole, fluconazole, griseofulvin, and miconazole, producing inhibition zones with diameters 0 mm, 0 mm, 8.5 mm, 0 mm, 17.25 mm, and 12.25 mm respectively at the end of the test. This study revealed that griseofulvin has the best antimycotic activity against M.gypseum and can be used as the drug of choice for the treatment of dermatophytosis caused by the fungi.

Abstrak: A mathematical method is introduced to represent a composite curve based on an extension of analytic geometry. The representation is given either with a single equation or with two equations, in the case of parametric representation. This method permits the representation of composite curves in similar manner to the conventional representation of non-composite curves. Some mathematical tools, including Heaviside unit step function and periodizer function, are used in the establishment of a single equation. In this paper, regular equations of regular and irregular polygon, as well as composite curves of two dimensions, are implemented using a computer algebraic system, Mathematica.
