Judul: Morfologi Kelenjar Parotis dan Mandibularis Musang Luak (Paradoxurus hermaphroditus)
Abstrak: This research was aimed to describe the morphology of the parotid and mandibular glands of Asian palm civet (Paradoxurus hermaphroditus). Four adult civets were used in this research which observed macroscopic and microscopically. The macroscopic observation had been done by observing the shape and size of the glands. The microscopic observation was done using hematoxylin-eosin, alcian blue pH 2.5 and periodic acid Schiff staining method. The parotid gland was of pure serous glands whereas the mandibular gland was of mixed gland. By using histochemistry method showed that the parotid gland gave negative reaction with alcian blue pH 2.5, whereas periodic acid Schiff gave positive reaction with moderate intensity in the serous acini cells while a weak intensity the duct lumen secretion. The mandibular glands gave positive reaction of both stains, a high intensity was detected in the mucous acini cells while a weak intensity was detected in duct lumen secretion with alcian blue pH 2.5. Periodic acid Schiff gave a high intensity in the serous acini while a moderate to high intensity was detected in the duct lumen secretion. In general, the characteristic of both glands were not similar with that of other carnivores. This may be caused by diet pattern differences.

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: Construction of Strongly Optimal Binary Linear Code with Minimum Distance 9 and 11
Abstrak: A binary linear code of length n over q F is a subspace of n q F . A code has three parameters that attached to it, namely length, dimension, and minimum distance. A code with length n, dimension k and minimum distance d is often called [n, k, d ]-code. Usually, when two parameters are given, then we want to find a code that has the best value for the last parameter. Based on Gilbert- Varshamov bound, if a [n, k, d ]-code exists and can not be expanded, we call it a strongly optimal code. In this paper, we construct strongly optimal code with minimum distance 9 and 11. In constructing the code, we created a theorem and algorithm based on Gilbert-Varshamov bound before we implement the algorithm to MAPLE programming language. Because of computational limitations, the program can only construct up to k = 10 for d = 9 and k = 12 for d = 11.
