Judul: Peningkatan Protein Onggok-Urea-Zeolit yang Difermentasi oleh Aspergillus niger (Cassabio) dengan Penambahan Amonium Sulfat sebagai Sumber Sulfur
Abstrak: Onggok merupakan limbah padatan yang berasal dari pembuatan tapioka ubi kayu. Limbah ini masih mengandung pati dalam jumlah yang tinggi akan tetapi sering menimbulkan masalah lingkungan, karena berpotensi sebagai polutan di daerah sekitar pabrik. Onggok dapat dimanfaatkan sebagai makanan ternak akan tetapi kandungan proteinnya rendah, kurang dari 5% dengan kandungan serat yang tinggi sekitar 35%. Salah satu teknologi alternatif untuk meningkatkan kualitas onggok adalah melalui proses fermentasi. Proses tersebut dapat dilakukan secara fermentasi padat dengan menggunakan kapang Aspergillus niger sebagai inokulum, ditambah campuran urea sebagai sumber nitrogen anorganik dan zeolit sebagai sumber mineral dan penyerap amonia dalam konsentrasi tinggi. Kualitas onggokurea- zeolit fermentasi (cassabio) ini dapat dioptimalkan dari segi kandungan protein kasar dan protein murni dengan penambahan amonium sulfat sebagai sumber nitrogen dan sulfur. Rancangan yang digunakan dalam penelitian ini yaitu Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 4 ulangan. Perlakuan tersebut terdiri atas AS1 (tanpa penambahan amonium sulfat), AS2 (penambahan amonium sulfat 0,5%), AS3 (penambahan amonium sulfat 1%) dan AS4 (penambahan amonium sulfat 1,5%). Hasil data yang diperoleh diolah dengan meggunakan analisis ragam (ANOVA) dan uji lanjut Duncan (Steel and Torrie, 1997).

Judul: Evaluasi Sifat Fisik Tepung Onggok-Urea-Zeolit yang Difermentasi Aspergillus niger (CASSABIO)
Abstrak: Onggok is solid waste from production of tapioca starch. This product contains high levels of starch and low crude protein. Cassava pulp can be used as feed for poultry by enriching the crude protein (CP). Onggok was added with 3% urea and 2.5% zeolite and was fermented by Aspergillus niger at 28-32 oC for six days. The product named cassabio. This research was aimed to evaluate physical characterstic, particle size, moisture content, pH, water activity and mash microstructure of cassabio compared with those of onggok. This research used t-test student with two treatments and four replications. The results of this research showed that the moisture, pH, Aw, specific density, bulk density, compacted bulk density, respone of angle of cassabio were significantly affect (P<0.05). Cassabio had lowest value for moisture, Aw and easy flow material than onggok. Difference existence of this physical properties indicated that every feedstuff had own specific character.

Judul: Etno-ornitologi Burung Kancilan Flores (Pachycephala nudigula nudigula Hartert 1897) pada Masyarakat Lio di Taman Nasional Kelimutu
Abstrak: Bare-throathed whistler is one of several wild birds in Kelimutu National Park (TNKL) that is believed to have correlation with Lio Community‟s belief. The estimation of Bare-throated whistler‟s population in Kelimutu National Park was about 186.41-1668.07 individual by the density about 0.0389-0.3481 ind/ha with the sex ratio 6.2:1 that spreaded on area with height of 1100 – 1600 masl. The characteristic of Bare-throated whistler‟s habitat is a natural forest with various canopy level, high plant species diversity and high density. The habitat characteristics related to the availability of food in the form of insects, cover, safety and a nesting site. Generally the most of Lio community knew the existence of Bare-throated whistler directly or from their parents‟ stories. The perceptions of Lio Community to the Bare-throated whistler‟s existence is generally support the conservation efforts. The perceptions construct the Lio Community‟s atitude that tend to be conservative to the existence of Bare-throated whistler. The attitude shown by their behavior that not cathing the Bare-throated whistler from the TNKL‟s area or the outside. The attitude have an important role to the existence of Bare-throated whistler in Kelimutu National Park‟s area.
