Judul: Pengembangan Kultur Kering Bakteri Lactobacillus plantarum (SK 5) asal Bekasam sebagai Kandidat Probiotik dengan Teknik Pengeringan Beku
Abstrak: Bakteri asam laktat asal bekasam memiliki potensi sebagai probiotik. Penelitian ini bertujuan untuk mendapatkan kultur kering bakteri L. plantarum (SK5) sebagai kandidat probiotik dan menganalisis pengaruh bahan pelindung dan suhu penyimpanan terhadap kultur kering L. plantarum (SK5) sebagai kandidat probiotik. Kriogenik yang digunakan adalah susu skim dan laktosa. Tahapan penelitian meliputi pengujian sifat kandidat probiotik bakteri L. plantarum (SK5), pembuatan kultur kering dengan metode pengeringan beku, analisis sifat kandidat probiotik kultur setelah proses pengeringan beku dan penyimpanan kultur kering pada suhu dingin dan suhu ruang. Bakteri L. plantarum (SK5) memiliki sifat sebagai kandidat probiotik dengan ketahanan pada pH 2, pH 7.2 dan garam empedu 0,5% masing-masing yaitu 87,2%, 88,5% dan 87,2%. Penambahan susu skim memberikan pengaruh yang berbeda nyata terhadap ketahanan hidup kultur kering beku pada kondisi pH 2, pH 7,2 dan garam empedu 0,5% dibandingkan laktosa dan kontrol. Penyimpanan pada suhu dingin dapat mempertahankan viabilitas kultur kering L. plantarum (SK5) lebih tinggi dari pada suhu ruang. Penambahan bahan pelindung susu skim pada kultur kering L. plantarum (SK5) dengan penyimpanan pada suhu dingin merupakan perlakuan terbaik.

Judul: Habitat characteristics of timor friarbird philemon inornatus in Camplong Landscape Kupang District, East Nusa Tenggara
Abstrak: Timor Friarbird (Philemon inornatus, G. R. Gray, 1846) is one of the six endemic birds of Timor and is a protected species. The population of bird is suspected to have been decreasing over the past six years along with the decreasing of the quantity and quality of physical and biotic factors of its habitat. Knowledge on landscape spatial pattern could be used to evaluate the quantity and quality of habitat. This research aimed at identifying spatial habitat characteristics of Timor Friarbird based on dominant factors of physical and biotic habitat components. Principle Component Analysis (PCA) on the physical habitat factors showed that variables that have strong correlation with the presence of the bird were Normalized Difference Vegetation Index (NDVI), slope, distance from secondary forest, distance from bush, distance from cashew plantation, distance from crop plantation, and distance from roads. The biotic factors that have strong correlation with the presence of Timor Friarbird were the total number of plant species, number of plants used for food and cover, and mean height of trees. Height of poles was the only variable that has no correlation with the presence of Timor Friarbird. The most dominant physical and biotic factors that influent the presence of Timor Friarbird at a site are the density of foraging trees, slope, distance from the river, the distance from secondary forest, the density of cover pole and the distance from road. The estimation population of Timor Friarbird in Camplong region is low; this might be caused by low feeding tree density, high rates of poaching, the uneven distribution of feed vegetation and the flowering season, habitat degradation due to illegal logging, grazing cattle in the wild, and invasion of siam weed or chromolaena (Chromolaena odorata). The results of land cover classification at Camplong region based on Landsat_5 Thematic Mapper (TM) image with ArcGIS 9.3 and Erdas 9.1 obtained 11 land cover classes, with shrub as the dominant class.
