Judul: Studi tentang Anatomi Alat Pencernaan dengan Tinjauan Khusus pada Lambung, Usus, Hati, dan Pancreas pada Kancil (Tragulus sp)
Abstrak: Kancil adalah hewan yang bernilai tinggi dari segi khasanah fauna di dunia. Daerah penyebarannya hanya di india, Thailand, Burma, Indocina Selatan, Malaysia dan Indonesia Barst. Kancil merupakan hewan ruminansia terkecil di dunia dan diperkirakan mempunyai potensi untuk dipakai sebagai hewan penelitian ruminansia.Telah dilalrulran penelitian terhadap 14 ekor kan - cil dewasa, jantan dan betina dengan tujuan mengungkap berbagai aspek anatomi slat pencernaan untuk menunjang dan memberi informasi bagi ilmu pengetahuan terutama fisiologi, biokimia, patologi dan ilmu bedah.

Judul: Karakteristik fisik dan organoleptik daging kancil(Tragulus javanicus)
Abstrak: Kancil (Tragulus javanicus) merupakan salah satu hewan asli Indonesia yang belum banyak diungkap, terutama karakteristik fisik daging. Kancil di habitat aslinya (hutan) banyak diburu untuk diambil kulit, daging atau organ tubuh kancil lainnya untuk berbagai keperluan atau sebagai sumber protein hewani. Penelitian ini bertujuan untuk mengetahui karakteristik fisik daging yang meliputi nilai pH, daya mengikat air (DMA), keempukan, besarnya susut masak dan warna serta sifat organoleptik yang meliputi warna, juiceness, keempukan, tekstur dan rasa dari daging kancil. Penelitian dilaksanakan di Laboratorium Lapang Ilmu Produksi Ternak (IPT) Perah, Bagian IPT Ruminansia Besar Fakultas Peternakan dan Laboratorium Kimia Pangan Pusat Antar Universitas (PAU) Pangan Institut Pertanian Bogor. Materi yang digunakan empat ekor kancil terdiri dari2 ekor jantan dan 2 ekor betina. Hasil dianalisa mengunakan statistika dan uji student-test...

Judul: Sythesis of Poly  (Hydroxy) Urethane from Polyol and Liquefied Spruce Bark for Wood Impregnation
Abstrak: The finding and application of environmentally benign wood preservatives is becoming paramount. Nontoxic and less leachable or degradable chemical have been suggested for exterior application. Polyurethanes synthesized through a green chemical pathway is very promising environmentally friendly wood modification processes. In this study, non-isocyanate route of polyurethane synthesis based on polyol (i.e. xylitol, sorbitol, liquefied spruced bark, glycerol and PG3), alkyl carbonate (i.e. DMC and DEC) and diamine (i.e. HMDA, EDA and DETA) was realized for wood impregnation through in-site polymerization. The structure and mass average molecular weight (Mw) of polyurethanes synthesized and impregnated were then analyzed by using FTIR, NMR and SEC. According to the results, synthesis of polyurethane by two pot method in water brought to cyclic carbonate degradation. The using of DEC in transcarbonatation reaction in two pot method gave similar characters of FTIR spectrum to the use of DMC, however the used of DMC was simpler than that of DEC. The synthesis of polyurethane by one pot method using different diamines confirmed the presences of carbamate function as analyzed by FTIR. However, the visual appearance of polymers produced showed that the use of HMDA as diamine resulted a solid product that was less water-soluble compared to that resulted from the used of EDA and DETA. The distribution of mass average molecular weight (Mw) of polyurethanes synthesized determined by SEC showed that the most satisfying polymer with Mw of 4380 g/mol was prepared without solvent. The reaction in water produced polymers with low Mw (less than 750 g/mol). Polyurethanes synthesized in methanol has higher Mw than that in water. In the same solvent, the use of HMDA resulted in a polymer with higher Mw than that of using EDA. Wood impregnations using one step method using solvent gave unsatisfactory WPG (about 12.59 – 19.71 %) and LC (about 50.36 – 62.80 %). One step impregnation without solvent gave higher WPG (about 78.39 – 87.63 %) and lower LC (19.11 – 21.25 %). However, wood impregnation without solvent is not feasible to be applied industrially. In other hands, five conditions of two step impregnations performed gave WPG of about 14.89 – 30.73 % and LC of about 42.22 – 56.52 %. In the case of two step impregnations without solvent, the first impregnation left inadequate space for the retention of the second step. It corresponds rather to leaching. Moreover, wood impregnation in two step faced a constrain of reaction stoichiometry. Since it is not applicable in charge with wood impregnation using methanol or ethanol as the solvent is more recommended by comparing with impregnation with an aqueous solution. However, it needs improvement on its resistance against leaching when used outdoor.
