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: Morfologi Organ Reproduksi Musang Luak Jantan (Paradoxurus hermaphroditus)
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.

Judul: Peran ZnO dan TiO2 pada Bioplastik Antimikroba Berbasis PLA-kitosan
Abstrak: Kemasan yang banyak digunakan sampai saat ini adalah plastik petrokimia yang bersifat non degradabel. Akibatnya berdampak pada pencemaran lingkungan. Untuk mengatasi masalah tersebut, dikembangkan bioplastik berbasis PLAkitosan dengan penambahan ZnO dan TiO2 untuk meningkatkan sifat antimikroba. Film dibuat dari PLA kemudian ditambahkan kitosan-ZnO dan kitosan-TiO2. Kemudian diuji aktivitas antimikroba, sifat mekanik, termal, dan permeabilitas uap air. Secara umum penambahan ZnO menghasilkan peranan yang lebih baik daripada TiO2. Penambahan ZnO pada PLA dan kitosan memperlihatkan aktivitas antimikroba terhadap bakteri; Salmonella typhi, Bacillus subtilis, Escherichia coli, Staphylococcus aureus, yeast; Candida albicans, dan jamur; Aspergilus niger. Film memiliki bentuk permukaan sedikit bergelombang dan berpori. Film mempunyai kuat tarik, modulus tarik, dan persen pemanjangan yang tergolong menengah bila dibandingkan dengan bioplastik sejenis lainnya. Film terdekomposisi pada suhu 275.83 °C dengan permeabilitas uap air sebesar 8,77x10-9 (g s-1 m-1 Pa-1).
