Judul: Pengaruh Karakteristik Habitat Ruang Terbuka Hijau terhadap Keanekaragaman Kupu-Kupu (Studi Kasus di Kebun Raya Bogor)
Abstrak: Bogor Botanical Garden (BBG) which functions as an ex-situ conservation places is one of the green open space (GOS) in Bogor and also home to many kinds of animals including butterflies. Butterfly serve as bioindicator of the ecological function of green open space. The purpose of this research was to determine diversity, eveness, and the similarity habitat use by butterflies on five habitat types in Bogor Botanical Garden in order to clarify the relationship between of biotic and abiotic factors in green open spaces and butterfly assemblages. This research was conducted from November to December 2011. Data collected were butterfly species and population, habitat characteristic, and vegetation analysis. Butterfly diversity was investigated by using line transect count method in five types of habitats which were surveyed in the morning (08:00-12:00) with three repetitions in the daytime under fine weather conditions. The following five transects were selected in this study: (1) Fruit plants habitat, (2) Mediterranean plants habitat, (3) Woody plants habitat, (4) Aquatic plants habitat, and (5) Garuda Garden. The diversity was calculated by using species diversity index (H’), eveness index (E) and similarity index (Sj). The relationships between biotic and abiotic factors to butterfly population were also determined. Based on survey in five sites, a total of 60 species belonging of five families : Papilionidae (7 species), Nymphalidae (33 species) Pieridae (13 species), Lycaenidae (6 species), and Hesperiidae (1 species) were captured and identified. Butterfly’s habitat preferences are: 1) The optimum temperature for a butterfly is between 28 0C-34 0C, 2) Buterflies originally found in relatively open habitats (large value of the GSF and small value of LAI), 3) Butterfly need a variety of larval host plant, nectar resources, and shelter, and 4) Have a water source, especially stagnant water source. This study shows that the provision of adequate nectar resources and larval host plant are likely to be essential to the successful conservation of butterfly species.

Judul: Dinamika Keanekaragaman Jenis dan Karakteristik Habitat Kupu-kupu di Kawasan Kampus IPB Darmaga
Abstrak: The diversity of wildlife including butterfly is one of the factors that becomes a consideration on the declaration of Bogor Agricultural Institute (IPB) as Campus Biodiversity. The development of land use at IPB Darmaga requires a research on the relationship between habitat characteristics with the diversity of butterfly as a comparison with the previous study to provide habitat management data for the management of IPB Darmaga campus. The study was conducted at eight habitat types in IPB Darmaga, which are: 1) Arboretum of Landscape, 2) Al Hurriyah Forest, 3) Sengon Forest, 4) Akasia Forest, 5) DAR Area, Faculty of Forestry, 6) Residential of Lecturers (Perumahan dosen), 7) Cikabayan and 8) Gymnasium Area. The result of this research gets 707 butterfly consisting 55 species of butterfly. Butterflies which were found consists of five families, namely Papilionidae (8 species), Nymphalidae (29 species), Pieridae (8 species), Lycaenidae (4 species) and Hesperidae (6 species). Residential of Lecturers (Perumahan dosen) habitat has the highest species diversity value of 2.93 with an average temperature characteristics of 30.330C, relative humidity average of 75.89%, the value of Leaf Area Index (LAI) of 1.507 and has a diversity of larvae feed plants, butterflies feed plants and shelters. Generally, species diversity index values and the number of butterfly species has decreased compared to previous studies due to changes in land use on IPB Darmaga campus that disturbs the habitat of butterfly.

Judul: Urolitiasis pada anjing
Abstrak: Urolitiasis adalah suatu penyakit dimana terjadi proses pengendapan batu pada traktus urinaria. Kalkuli yang paling banyak dijumpai pada kasus urolitiasis anjing adalah kalkuli magnesium amonium fosfat (struvite), jika dibandingkan dengan kalkuli oksalat, sistin dan urat (Osborne et al., 1982). Infeksi oleh Staphylococcus aureus pada traktus urinaria memgang peranan penting dalam proses pembentukan kalkuli, karena bakteri tersebut dapat menghasilkan enzim urease, raktor predisposisi tidak dapat dinisankan dari infeksi traktus urinaria. Pada anjing, tempat yang banyak didapati pengandapan kalkuli adalah kantung air kemih dan uretra, sedangkan pada ginjalnya jarang. Pada anjing jantan lebih sering kejadiannya dibanding dengan pada anjing betina, karena anatomi traktus urinaria pada anjing jantan lebih memungkinkan untuk terjadinya obstruksi, yaitu lebih panjang dan sempit. Besarnya, kalkuli bervariasi, dari kecil dan halus seperti pasir sampai besar dan kasar seperti batu karang. ...
