Judul: Studi perbandingan fisio anatomi saluran pencernaan kambing dan domba lokal
Abstrak: The objectives of the experiments were to compare the physio anatomy of gastro intestinal tracts between local goats and local sheep. The experiments were conducted held from March to July 2005. The experiments used ten goats (5 males and 5 females) and ten sheep (5 males and 5 females). The experimental design used was Randomized block design with factorial (2x2). Significant differences among treatments futher tested with Duncant test. The results showed that relative volume of total stomach and weights of stomach tissue to empty body weight were not significantly differences, retekulo-rumen, omasurn and abomasum volume had significantly differences, weights of tissue retikulo-nunen, omasum and abomasum to empty body weight were not significantly differences for species and sexs., Relative of abomasum volume was large significantly (P<0.05) in male goat, Small intestine length to bone length, retention time was large significantly (Pi0.05) in sheep more than goat.

Judul: Studi perbandingan sifat fisik alat pencernaan antara kambing dan domba pada lingkungan nutritif yang berbeda
Abstrak: ivers Penelitian ini dilakukan di Laboratorium Ilmu Produk- si Ternak Ruminansia Kecil, Fakultas Peternakan, Institut Pertanian Bogor. Penelitian dilakukan dari bulan November 1989 sampai dengan Februari 1990. Tujuan dari penelitian ini adalah untuk mengetahui dan membandingkan sifat fisik alat pencernaan antara kam- bing dengan domba pada lingkungan nutritif yang berbeda dalam rangka hubungannya dengan efisiensi penggunaan ma- kanan dan optimalisasi produksi daging. Jumlah ternak yang digunakan adalah 18 ekor jantan lokal dan 18 ekor kambing Kacang jantan. masing jenis ternak tersebut diberi tiga perlakuan domba Masing- ransum yaitu ransum dengan protein 1, 1.5 dan 2 kali standar NRC. Bahan makanan yang digunakan terdiri atas rumput lapang, bungkil kedele, jagung kuning dan kalsium karbonat yang disusun berdasarkan kebutuhan. Rancangan percobaan yang digunakan adalah Rancangan Acak Lengkap. Analisa data dilakukan dengan Analisa Sidik Ragam (ANOVA). Hasil penelitian menunjukan, bahwa domba lokal mempu- 1230.9 gram, jaringan oesophagus 40.15 gram, jaringan ruret 402.07 gram, jaringan omasum 36.83 gram, jaringan abomasUA 84.67 gram, jaringan usus halus 479.7 gram, jaringan colon 147.2 gram, jaringan sekum 40.33 gram serta panjang halusnya 22.02 meter. Pada kambing rataan usus bobot total jaringan alat pencernaan 870.9 gram, jaringan oesophagus 43.75 gram, jaringan ruret 258.17 gram, ja ngan omasum 36.83 gram, jaringan abomasum 54.17 gram, jaringan usus halus 336.17 gram, jaringan colon 118.17 gram, jaringan sekum 40.50 gram serta panjang usus halusnya 17.65 meter. Domba mempunyai bobot total jaringan alat pencernaan, jaringan rumen-retikulum, abomasum, usus halus dan panjang USUS halusnya lebih berat dan panjang (p<0.05) daripada kambing, sedangkan perlakuan ransum pada domba maupun kambing tidak menunjukkan perbedaan yang nyata terhadap sifat fisik jaringan alat pencernaan. Hasil penelitian ini menunjukan bahwa ransum dengan kandungan protein sama dengan rekomendasi NRC lebih efisisien dan ekonomis dibanding dengan ransum lainnya….

Judul: Elektrodeposisi Film Tipis Semikonduktor Cu2ZnSnS4 (CZTS) pada Substrat Kaca ITO
Abstrak: Semiconductor Cu2ZnSnS4 (CZTS) thin film that can be used as absorber layers on solar cell module was made via electrodeposition method. CZTS thin film was electrodeposited on the surface of a silicate glass coated with a thin layer of indium tin oxide (ITO). Deposition process was done using potentiostatic mode at room temperature with a potential of 1.05 V for 30, 45, and 60 minutes, followed with annealing the film at 2 different temperatures, 500 ºC using furnace and 180 ºC using hot plate, both treatments for 45 minutes in N2/H2S atmosphere. The X-ray difractograms were analyzed using Match 2 program and showed that the CZTS thin films had kesterit crystalline structure, with a low percentage of CZTS phase. The thin film also contained secondary phases such as Cu2S, ZnS, and SnS. The obtained CZTS thin films had a thickness between 1.039 and 1.676 μm. Absorption study showed that the band gap energy of CZTS thin films which was annealed using furnace ranged from 1.50 to 1.52 eV, whereas that annealed using the hot plate was not observed. The band gap energy value showed that CZTS thin films can be used as sunlight absorber layers on solar cell. The formation of CZTS crystal film on this investigation was effectively performed using furnace annealing process at a temperature of 500 ºC with deposition time of 45 minutes.
