Judul: Pengaruh Ransum Dengan Tingkat Subtitusi Jerami Kedelai Yang Berbeda Terhadap Saluran Pencernaan  Termasuk Hati Dan Pankreas Kelinci Lokal Jantan
Abstrak: Penelitian ini dilakukan di Laboratorium Ilmu Produksi Ternak Daging dan Kerja, Jurusan Ilmu Produksi Ternak, Fakultas Peternakan, Institut Pertanian Bogor, selama enam minggu sejak tanggal 28 Januari sampai dengan tanggal 11 Maret 1984. Tujuan penelitian ini adalah untuk mempelajari pengaruh tingkat substitusi jerami kedelai ke dalam ransum kelinci terhadap saluran pencernaan termasuk hati dan pankreasnya. Penelitian ini juga untuk mempelajari respon kelinci terhadap jerami kedelai. Dalam penelitian ini, digunakan 40 ekor kelinci lokal jantan dengan bobot tubuh berkisar 550 sampai 1000 g. Lima macam ransum, yaitu R1, R2, R3, R₁ dan R, diberikan dalam bentuk pellet yang terdiri atas ransum dasar dengan substitusi jerami kedelai masing-masing 0, 10, 20, 30 dan 40%. Ransum dasar disusun dari bahan dedak padi halus, dedak jagung, bungkil kelapa, onggok dan tepung ikan masing-masing 42.5, 20, 15, 15 dan 7.5%. Ransum dasar memenuhi kebutuhan kelinci yang sedang tumbuh. Kandang yang digunakan ada- lah kandang individual, 30 x 40 x 30 cm, disusun dengan ketinggian 75 cm dari lantai kandang yang berukuran 22 x 2m. Ruangan kandang dilengkapi dengan sebuah kipas angin listrik berukuran sedang. Rancangan percobaan yang digunakan adalah rancangan acak lengkap dengan lima perlakuan dan delapan ulangan. Analisis peragam (Covariance) model Y Ti ax, digunakan untuk mempelajari pengaruh ransum terhadap bobot dan panjang saluran pencernaan dan bagian-bagiannya termasuk hati dan pankreas (Y) pada bobot tubuh kosong, bobot total saluran pencernaan, serta untuk isi saluran pencernaan total dan bagian-bagian saluran pencernaan pada bobot potong dan bobot total isi saluran pencernaan (X) yang sama. Ti adalah perlakuan dengan 11, 2, 3, 4 dan 5. Semua analisis, mengikuti petunjuk Snedecor dan Cochran (1967). ...

Judul: Pengaruh pemberian ransum Dengan Tingkat Subtitusi Jerami Kacang Kedelai Yang Berbeda Terhadap Potongan Komersial Karkas Kelinci Lokal Jantan Dan Produksinya
Abstrak: Pengaruh pemberian ransum dengan tingkat subtitusi Jerami kacang kedelai yang berbeda terhadap potongan komersial karkas kelinci lokal jantan dan produksinya dipelajari di Laboratorium Ilmu Produksi Ternak Daging dan Kerja, Fakultas Peternakan, Institut Pertanian Bogor, dari 29 Januari sampai 12 Maret 1984. Sebanyak empat puluh ekor kelinci lokal jantan dengan bobot awal 500 sampai 1 000 gram dibagi menjadi lima kelompok yang merupakan perlakuan. Setiap perlakuan terdiri dari delapan ulangan. Perlakuan I tidak diganti dengan jerami kacang kedelai, perlakuan II diganti dengan 10% jerami, perlakuan III diganti dengan 20% jerami, perlakuan IV diganti dengan 30% jerami dan perlakuan V diganti dengan 40% jerami. Penelitian dilakukan dalam rancangan acak lengkap selama enam minggu. Ransum dan miniman diberi ad libitum. Semua Kelinci dipotong pada akhir penelitian dan karkasnya dipotong-potong dan dipisahkan daging dan tulangnya. Potongan sesuai dengan yang dilakukan Herman et al. (1983). Pengaruh perlakuan dianalisa dengan analisa covarian dengan model Y = Tax.

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.
