Abstrak: This research was aimed to study the morphological anatomy of the reproductive organs of male Asian Palm Civet (Paradoxurus hermaphroditus). This research studied the reproductive organs of two male Asian Palm Civets at a macroscopic and microscopic level. Macroscopic observation was done directly to study the morphometry which included the length, diameter and weight of the male reproductive organ. Microscopic observation was done using histochemical method with Hematoxillin-Eosin and Masson’s Trichrome staining. The acquired data were analyzed descriptively. Result of this research showed that the length, diameter and weight of testis without scrotum were 2.14 cm, 1.55 cm and 2.85 g respectively. The epididymis consist of caput, corpus and cauda epididymis. The prostate gland observed macroscopically had a length, height and weight of 3.14 cm, 1.82 cm, and 4.21 g respectively. The penis was a musculo-cavernosus type with a penis spine in the glans penis and was 7.77 cm in length. Prostate gland, which was histologically observed around the urethra pelvina, had a mucous type. Generally, the anatomy of the male Asian Palm Civet reproductive organ was similar to that of other carnivores such as cat and dog.

Abstrak: The study was aimed to describe the morphology of female reproductive organ of the Asian palm civet (Paradoxurus hermaphroditus). This study was used three females of Asian palm civet that examined using macroscopic and microscopic observation. Microscopic observation was done using Hematoxillin-Eosin and Masson’s trichrome staining methods. The female reproductive organs of Asian palm civet were consisted of ovary sinister and dexter, oviducts, uteri, vagina, vestibule, and vulva. The average weight of dexter and sinister ovaries were 0,18±0,09 and 0,19±0,09 g respectively. The length of dexter and sinister ovaries, oviduct, cornua uteries, and corpus uteries were 0,79±0,23 and 0,77±0,26; 3,82±1,49 and 3,85±1,43; 3,04±0,22 and 3,27±0,60, 2,32±0,12 cm respectively. The length of cervix, vagina, and vestibule were 0,97±0,44, 1,27±0,44, and 0,71±0,22 cm respectively. Ovaries of Asian palm civet were consisted of cortex and medula. The oviduct has mucosa folds and the epithelium was found no cilia. Endometrial glands were found in cornua and corpus uteri. Macroscopically and microscopically, the structure of the female reproductive organs were very similar to those cat and dog.

Judul: Pemanasan Sekunder Reaksi Fusi Plasma dengan Menggunakan Radio Frequency
Abstrak: Plasma merupakan bentuk ke-empat dari materi setelah padat, cair dan gas yang terbentuk dari proses ionisasi gas. Plasma dapat digunakan dalam reaksi fusi, yaitu reaksi penggabungan dua inti atom ringan menjadi inti atom yang lebih berat sambil melepaskan energi. Untuk mendapatkan energi dari reaksi fusi, inti yang akan direaksikan harus dipanaskan pada temperatur yang sangat ekstrem tingginya. Salah satu cara agar dapat mencapai kondisi ini adalah memberikan pemanasan tambahan atau pemanasan sekunder kepada plasma dalam reaksi fusi tersebut. Nilai daya serap rata-rata ion Deuterium yang sesuai dengan selang nilai daya dari data ITER adalah daya yang menggunakan frekuensi 50 MHz sampai dengan 60 MHz. Dengan menggunakan frekuensi 60 Hz diperoleh nilai daya rata-rata yang diserap sebesar 1,235.10-12 W.
