Abstrak: This study was aimed to describe the morphology of esophagus and stomach of barn owl (Tyto alba). Two barn owl (T. alba) were used to observed macroscopic and microscopically. The macroscopic observation was done by observing the shape and size of the esophagus and stomach. The microscopic observation was done using standard histological method with hematoksilin eosin (HE) staining. The results showed that the esophagus consist of pars cervicalis and pars thoracalis, was 9.8 centimeters in length, and possessed no crop. Mucosa of the esophagus pars cervicalis was lined with nonkeratinized stratified squamous epithelial cell, and the pars thoracalis lined by simple columnar epithelial cell. The esophageal gland was mucous type distributed in a lot number along the mucosa. The external muscle consists of two layers, which were the inner longitudinal muscle and outer circular muscle. The stomach could be distinguished into proventriculus and ventriculus (gizzard). Proventriculus was a cone shape and gizzard was cuboid with an average length of the greater curvature was 6.5 cm and was 1.88 cm in diameter. The mucosa of proventriculus was lined by simple columnar epithelium. The proventricular gland was consist of superficial and profundal glands. The superficial gland produced mucous, while the profundal produced pepsinogen and hydrochloric acid (HCl). The external muscle layer consist of three layers, two longitudinal muscles in the superficial and profundal layers and circular muscle in the middle between the two of longitudinal muscles. The mucosa of gizzard was lined with simple columnar epithelial cell, with the thin cuticle. The gizzard glands consist of simple tubular gland that produced mucous. The gizzard has two very thick muscle layers composed by inner longitudinal muscle and the outer circular muscle. The characteristic morphology of the esophagus and stomach of barn owl (T. alba), was presumed to supports their behavior, which swallow a whole body of their prey.

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: Sintesis Ramah Lingkungan Nanopartikel Cu Dan Zn Serta Aplikasinya Sebagai Katalis Deklorinasi Diklorometana
Abstrak: Nanopartikel Cu dan Zn disintesis dengan metode reduksi kimia menggunakan pereduksi ramah lingkungan. Pereduksi yang digunakan ialah glukosa, laktosa, maltodekstrin, high fructose syrup (HFS), madu, dan pati. Waktu pemanasan dan konsentrasi pereduksi optimum untuk sintesis nanopartikel Cu adalah 270 menit dan 10,000 ppm, sedangkan untuk nanopartikel Zn adalah 90 menit dan 15,000 ppm. Pereduksi terbaik dalam sintesis adalah glukosa karena membentuk nanopartikel Cu dan Zn dengan konsentrasi yang tinggi. Aglomerasi dan terganggunya sistem koloid akibat pengendapan dan flokulasi memengaruhi ukuran dan kestabilan nanopartikel. Dalam percobaan ini ditambahkan polivinilpirolidon (PVP) sebagai penstabil dengan konsentrasi 0%, 1%, dan 5%. Hasil kestabilan terbaik nanopartikel Cu dan Zn merujuk pada pereduksi madu yang ditambahkan PVP 1%. Nanopartikel Cu dan Zn dapat diaplikasikan sebagai katalis deklorinasi diklorometana (DCM). Nanopartikel Cu mendegradasi DCM hingga 93.85%, lebih tinggi dibandingkan nanopartikel Zn.
