Abstrak: The study was aimed to explore the intestinal morphology of Asian palm civet. It included histochemical study on the distribution of acid and neutral carbohydrates component along the intestine of Asian palm civet. This study used three preserved intestinal organs of Asian palm civet. The sample was studied using macroscopic and microscopic approach of observations. The macroscopic observations were done by focusing on morphometric of the intestine. The microscopic observations were done by preparing histological slides and staining with hematoxylin eosin (HE), alcian blue (AB) pH 2.5, and periodic acid Schiff (PAS). The results showed that Asian palm civet’s caecum was curved like a comma and the colon was short without segment. The average length of the intestine were 140.06±13.09 centimeters. The lenght ratio of intestine to body were 1:3 that was noted as in between insectivores and carnivores. Asian palm civet intestinal’s wall was composed of inner mucosa, submucosa, tunica muscularis, and outer serosa with varying in thickness. There were submucosal lymphatic tissue in ileum that formed Peyer’s patches and solitary lymphatic nodules in caecum. The distribution of acid and neutral carbohydrates were found in the intestinal mucosal in goblet cells and glandular epithelial of crypt Lieberkuhn. The Brunner’s glands only were gave positive reaction to PAS staining. The morphology of the intestine of the Asian palm civet more closely to those on carnivores than those which found in omnivores.

Judul: Morfologi Esofagus dan Lambung Musang Luak (Paradoxurus hermaphroditus)
Abstrak: This research was aimed to describe the morphology of the esophagus and stomach of Asian palm civet (Paradoxurus hermaphroditus). This study was used organs from three Asian palm civets which observed macroscopic and microscopically. The macroscopic observation had done by observing the shape and the size of the esophagus and stomach. The microscopic observation was done using histochemical method with hematoksilin eosin (HE), alcian blue (AB) pH 2.5, and periodic acid Schiff (PAS) staining methods. The results showed that the esophagus were 17.3 centimeters in length and 1.06, 0.72, 0.83 centimeters in diameters of cranial, medial, and caudal portion respectively. The esophagus was lined with nonkeratinized stratified squamous epithelium, has no esophageal glands, and more than half was consist of skeletal muscle. The stomach of Asian palm civet was a J shape with the greater curvature about two times longer than the lesser one. The glandular stomachs were composed of cardiac, fundic, and pyloric glands. Fundic glands were characterized by the presence of mucous cells, chief cells and a great number of parietal cells. At the border between pylorus and the duodenum was found a thin of pyloric sphincter muscle. Brunner glands were found in the submucosal area of pylorus near the border. The AB and PAS stain showed neutral carbohydrates were dominant on the surface of the esophagus and the glandular

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.
