Judul: Mempelajari Pengaruh Jenis Kultur dalam Pengeringan Beku dan Lama Penyimpanan terhadap Mutu Kultur Starter Yogurt
Abstrak: Yogurt telah clikenal sebagai salali satu jenis makanan mi~ltifungsional yang sangat penting peranannya bagi kesehatan manusia. Penanganan kultur starter yogurt dala~n bentuk cnir, niemerl~ikan banyak tennga dan biaya karena kultur harus disi~ilpaii dalaln leniari es dan setiap satu minggu ltultur liarus disegarkan kembali. Oleh karena it11 perlii penysdiaan kultur starter dalam bentuk kering, yang akan memudahltan cara penanganannya dan mernirngkinkan penggunaan kultur starter bar11 pada setiap lot fermentasi, seliingga fernientasi lebih terkontrol dan kualitas produk lcbih terjaniin. Ketersediaan ltultur starter kering juga akan mempermudah distribusi dnii transportasi kultur starter kru.cna ltultur starter ltering dapat dikirim untuk jarak jauh tanpa 1;ehilangan alitifitas yang nyata.

Judul: Mempelajari Pengaruh Bahan Pelindung dalam Pengeringan Beku dan Lama Penyimpanan terhadap Mutu Kultur Starter Yogurt
Abstrak: Yogurt adalah salah satu jenis minuman hasil fermentasi susu menggunakan bakteri Streptococcus thermophi/lis dan Lactobacillus bll/garicus. Menurut Winarno (1980), fermentasi biasanya dilakukan dengan menggunakan kultur murni yang dihasilkan di laboratorium dan dapat disimpan dalam keadaan kering atau dibekukan «((om pas, 27 Juli 1980). ((ultur bakteri asam laktat yang dikeringkan l1laupun dikeringbekukan telah banyak diproduksi dalal11 skala industri. ((el1ludahan untuk memperoleh kultur starter tersebut l11enguntungkan dari segi transportasi dan penyimpanan (Suarni, 1990). Pembekuan dan penyimpanan yang lama pada suhu _40°C dapat menyebabkan teljadinya kerusakan aktivitas kultur starter. Proses pembekuan dan pengeringan juga dapat merusak sel bakteri, tetapi kerusakan tersebut dapat diminimumkan dengan pcnumbahan bahan peiindung tertentu sebelum pembekuan dan pengeringan (Tamime, 1981).

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.
