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: Studi Perbandingan Penampilan Umum dan Kecernaan Pakan pada Kambing dan Domba Lokal
Abstrak: Menurut Devendra dan Burns (1994) kambing dan domba memiliki sistem pencernaan yang serupa, sehingga kedua jenis ternak ini sering dianggap sama. Namun menurut Tomaszewska et al. (1993) terdapat perbedaan dalam tingkah laku dan fisiologi pencernaan. Adanya persamaan dan perbedaan tersebut dapat menyebabkan persamaan dan perbedaan pada penampilan. Untuk mengetahui persamaan dan perbedaan penampilan kedua ternak tersebut maka perlu dilakukan studi perbandingan penampilan kambing dan domba lokal dengan perlakuan yang sama. Penelitian ini dilaksanakan di Laboratorium Lapang Nutrisi Ternak Daging dan Kerja. Analisa dilakukan di Laboratorium Nutrisi Ternak Daging dan Kerja dan Laboratorium Nutrisi Ternak Perah, Departemen Ilmu Nutrisi dan Makanan Ternak Fakultas Peternakan, Institut Pertanian Bogor. Penelitian ini berlangsung dari bulan April sampai Juli 2005. Ternak yang digunakan adalah 10 ekor kambing dan 10 ekor domba lokal lepas sapih yang masing – masing 5 ekor jantan dan 5 ekor betina. Rataan bobot awal kambing jantan 10,92 kg +1,56 kambing betina 9,68 kg + 1,02 dan domba jantan 14,16 kg + 2,56 domba betina 13,4 kg + 3,15.

Judul: Characteristic of Overshooting Top (OT) Based on  Himawari  8  Satellite  as  a  Convective  Cloud  Feature  that  Generates  Extreme Weather in the Java Island Region
Abstrak: Overshooting Top (OT) is a feature at the top of a convective cloud that is associated with extreme weather. Research on OT in tropical Indonesia is still very limited. The existence of geostationary satellites with wide area coverage and fast frequency observations is useful for observing the fast dynamics of the OT life cycle. Therefore, this study intends to analyze the relationship between OT and extreme weather, updraft and thermodynamic conditions of OT when extreme weather occurs, the best objective method for detecting OT in the day time and night time, and the spatiotemporal distribution of OT in the tropical region of Java Island during the 2018-2021 period. Based on visual analysis using visible channel and Himawari 8 sandwich products, 87% of extreme weather events in Java were accompanied by the appearance of OT. It indicates that the presence of the OT pattern is a convection cloud pattern or feature that is closely related to extreme weather events for the Java Island region. The existence of a time lag between the appearance of OT and extreme weather events on Java Island indicates that the OT of convection cloud can be used as a precursor or nowcasting for the appearance of extreme weather. Most of the convective cloud OT features during extreme weather events on Java Island have altitude that were only able to exceed the altitude of the equilibrium level and few were able to exceed the tropopause level of 9 km – 16 km. The difference in atmospheric conditions during extreme weather events on Java Island, which is in the tropics and subtropics, is a strong and unstable convective energy condition characterized by a larger CAPE, as well as unstable KI, LI, SI and TTI values. It is offset by kinematic factors in the form of a weak vertical wind shear (bulk wind shear 0-6 km) and a higher freezing point height. The difference between extreme weather events in the Java Island region and other tropical regions compared to subtropical regions is the strong updraft speed of convection clouds. The IRW Texture COMB algorithm based on the IRW-Texture Gradient modification and the COMB algorithm shows a significant increase in quality for detecting OT and non-OT pixels in Java. Rainy days with rainfall > 50 mm/day are very common in areas with an altitude of > 500 m. On the other hand, the level of convection activity which is indicated by the presence of OT and lightning is significantly reduced in this area. OT of convective clouds appear more frequently during the DJF season and less frequently during the JJA season. OT often appears during the day time and rarely at night time. Most OTs appear in the central part, away from the south and north coasts of Java Island during the day, while OTs that appear near the south and north coasts of Java Island can appear in the morning or afternoon.
