Judul: Keanekaragaman Lumut di Jalur Pendakian Cemoro Sewu Gunung Lawu, Jawa Timur.
Abstrak: Tropical forests have higher diversity of bryophytes species than other regions in the world. Diversity and abundance of bryophytes depend on the altitude. This study aims to inventory the diversity of bryophytes of Mount Lawu and their distribution based on the altitude and type of substrate. Sampling was carried out along a hiking trail of Cemoro Sewu. Total of 85 species (34 families, 56 genera), consist of 55 species of mosses (17 families, 35 genera), 28 species of leafy liverworts (15 families, 19 genera), one thalloid liverworts, and one hornworts species were found in the study. Dicranaceae (19 species, seven genera) and Bryaceae (eight species, four genera) have higher much of species. Those mosses were found mostly terrestrial growing on rock substrate. Bryophytes distribution evenly on upper mountain zones as well as at sub-alpine zone. The diversity of leafy liverworts more higher in the mountain zone (2000-3000 masl) than in sub-alpine zone (3000-3265 masl).

Judul: Diversitas Lumut Epifit di Tiga Perkebunan Teh Jawa Barat
Abstrak: Study on the epiphytic bryophytes was conducted at three tea plantations located at different elevation in West Java: Gunung Mas (600 m) Bogor, Nirmala (1150 m) Sukabumi, Rancabali (1628 m) Bandung. Three plots were established within each tea plantation, three transects of 30 m were lined in each plot. Samples were collected from the trunk and primary branches of five tea trees in each line transect. The aims of this study were to record the epiphytic bryophytes species of the plantations and to compare diversity of the bryophytes community among the plantations. Ninety species of epiphytic bryophytes were recorded. Checklist of those species were provided in this paper. The bryophytes species richness of the plantations increased with increasing of the elevation. Twenty seven species were found at Gunung Mas, 40 species at Nirmala, and 74 species at Rancabali. The plantations were dominated by different species. The dominant species were Sematophyllum tristiculum (mosses) at Gunung Mas, Lejeunea anisophylla (liverworts) at Nirmala, and Acanthocoleus javanicus (liverworts) at Rancabali. The species composition of the bryophytes communities of Gunung Mas was more similar to that of Nirmala compared to that of Rancabali.

Judul: Pengaruh Vaksin Newcastle Disease-QV4 Terhadap Kinerja Ayam Pedaging.
Abstrak: Penelitian ini dilakukan untuk mengetahui kinerja ayam yang divaksin aktif ND QV4 apathogenic. Penelitian menggunakan 100 ekor ayam pedaging dan dibagi menjadi 40 ekor ayam vaksinasi, 40 ekor ayam tidak divaksinasi, dan 20 ekor ayam sebagai kontrol serta dilakukan pemisahan ayam pada hari ke 29 untuk uji tantang virus yaitu 10 ekor ayam diambil dari ayam yang divaksin dan 10 ekor ayam diambil dari ayam yang tidak divaksin. Setiap hari dilakukan perhitungan konsumsi pakan dan setiap minggu dilakukan penimbangan bobot badan. Hasil penelitian menunjukkan vaksin berpengaruh terhadap bobot badan dan kerja vaksin optimal dalam melindungi ayam dari infeksi ND sehingga ketika ditantang virus ND ayam memiliki bobot badan yang tinggi. Nilai FCR ayam menunjukkan infeksi virus ND dan vaksinasi dapat menurunkan efisiensi makanan. Nilai IP ayam menunjukkan vaksinasi yang diberikan tidak mampu meningkatkan kinerja ayam dan lebih memperburuk jika ditantang oleh virus ND.
