Judul: Hubungan Faktor Lingkungan dengan Keanekaragaman Jenis Kupu-Kupu di Tebet Eco Park, Jakarta Selatan
Abstrak: Populasi kupu-kupu berkaitan dengan faktor lingkungan pada suatu habitat, sehingga rentan terhadap perubahan kualitas lingkungan yang terdiri dari faktor abiotik dan biotik. Tebet Eco Park merupakan Ruang Terbuka Hijau yang sesuai untuk habitat kupu-kupu di tengah perkotaan. Penelitian bertujuan untuk mengkaji keanekaragaman dan komposisi jenis kupu-kupu pada dua area taman dan menganalisis pengaruh faktor lingkungan terhadap keanekaragaman jenis kupu-kupu di Tebet Eco Park. Metode pengumpulan data kupu-kupu menggunakan kombinasi metode transek dan titik hitung serta metode jebakan. Analisis Biplot dan korelasi Pearson digunakan untuk menentukan keeratan hubungan antara faktor lingkungan dengan keanekaragaman jenis kupu-kupu. Terdapat 761 individu dari 27 jenis kupu-kupu yang terdiri dari seluruh famili kupu-kupu tersebar di Taman Utara dan Taman Selatan. Indeks Keanekaragaman Jenis dan Indeks Kemerataan Jenis tertinggi diperoleh Taman Utara pada pagi hari (H’ = 2,524; E = 0,857), namun Indeks Kekayaan Jenis tertinggi diperoleh Taman Selatan pada pagi hari (Dmg = 3,903). Seluruh data keanekaragaman jenis kupu-kupu pada pagi hari lebih tinggi dibandingkan dengan siang hari. Intensitas cahaya matahari berkorelasi negatif sangat kuat terhadap keanekaragaman jenis kupu-kupu., Butterflies act as environmental bioindicators, so they are very susceptible to changes in environmental quality consisting of abiotic and biotic factors. Tebet Eco Park is a green open space that is suitable for butterfly habitats in the middle of urban areas. The research aimed to identify the diversity of butterfly species in two park areas and analyze environmental factors in the two areas that can influence the diversity of butterfly species in Tebet Eco Park. The butterfly data collection method uses a combination of transect and point counting methods and trap methods. Biplot analysis and Pearson correlation were used to determine the close relationship between environmental factors and butterfly species diversity. There were 761 individuals of 27 types of butterflies consisting of all butterfly families spread across North Park and South Park. The highest species diversity index and species evenness index values were found in North Park in the morning (H' = 2.524; E = 0.857), while the highest richness index was found in South Park in the morning (Dmg = 3.903). All data on butterfly species diversity in the morning is higher than in the afternoon. The intensity of sunlight has a very strong negative correlation with the diversity of butterflies.

Judul: Keanekaragaman Jenis Kupu-kupu pada Beberapa Tipe Habitat di Pondok Ambung Taman Nasional Tanjung Puting Kalimantan Tengah
Abstrak: Tanjung Puting National Park, has megabiodiversity which still unexplorated all of them. Butterflies as part of biodiversity which still unexplorated, has important role as pollinator and with it’s wonderful colored wings has high value economically. Purposes of this study are to identified species diversity of butterflies in several habitat types and to analyze species richness, species diversity, evenness, and similarity of butterflies in every habitat types and to analyze correlation between habitat characteristics and species diversity of butterflies includes species richness, species diversity, and evenness of butterflies. This study conducted for two months from July to August 2009 in Pondok Ambung, Tanjung Puting National Park, Central Kalimantan, which located in eight different types of habitats included lowland forest, swamp forest, peat swamp forest, kerangas (dry-land habitat), grassland, burned forest, Camp Ambung, and nursery camp. The method used is by transect method in length 500 m, one transect for every habitat types, by method of sweeping and trapping used rambutans and watermelon as trap bait. Data collected were butterflies species, individuals per species, habitat characteristics included structure, composition, types of vegetation and physics and biotic component of habitat. Data analysis included species richness, species diversity, evenness, similarity coefficient, vegetation analysis, and correlation analysis between habitat characteristics and butterflies diversity. During the study, a total of 76 butterflies species were recorded included family of Papilionidae (11 species), Pieridae (6 species), Nymphalidae (43 species), Lycaenidae (14 species), and Hesperiidae (2 species). Species number for every type of habitat founded lowland forest 33 species, swamp forest 24 species, peat swamp forest 13 species, kerangas (dry-land habitat) 20 species, grassland 11 species, burned forest 27 species, Camp Ambung 37 species, and nursery camp 32 species. The highest for species richness is Camp Ambung and the lowest is grassland area. For species diversity the highest is lowland forest and the lowest is grassland. Types of habitat with low scale for evenness are grassland and burned forest. Types of habitat with highest scale for similarity are between Camp Ambung and nursery camp and the lowest are between peat swamp forest and grassland. There is founded a relation between habitat condition and butterflies diversity which depend on temperature and relative humidity, open area, water source, and vegetation as food plant, shelter, and cover for butterflies.

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. ...
