Judul: Pengaruh pertumbuhan Akibat Perbedaan Pemberian Ransum Terhadap Saluran Pencernaan Kelinci Lokal Jantan
Abstrak: Penelitian ini dilakukan di Laboratorium Ilmu Produksi Ternak Daging dan Kerja, Fakultas Peternakan, Institut Pertanian Bogor dari tanggal 5 April 1983 sampai dengan 23 Juni 1983. Tujuan dari penelitian adalah untuk mempelajari pengaruh pertumbuhan akibat perbedaan pemberian ransum terhadap saluran pencernaan kelinci lokal jantan. Ternak yang digunakan adalah 30 ekor kelinci lokal jantan lepas sapih dengan bobot awal 520.90 gram sampai dengan 651.30 gram, yang dibagi menjadi tiga kelompok masing-masing 10 ekor. yaitu kelompok pertumbuhan lambat (A), pertumbuham lambat cepat (B) dan pertumbuhan cepat (C). Penelitian ini dilakukan dalam Rancangan Acak Lengkap. Untuk mempelajari pengaruh perlakuan terhadap saluran pencernaan, digunakan Analisis Peragam (Co-variance) Model Y= T1 axb.

Judul: Pengaruh pertumbuhan akibat Perbedaan Cara Pemberian Ransum Terhadap Bobot Karkas Dan Komponen Karkas Kelinci Lokal jantan
Abstrak: Penelitian ini dilakukan di Laboratorium Ilmu Produksi Ternak Daging dan Kerja, Fakultas Peternakan, Institut Pertanian Bogor dari tanggal 5 April sampai dengan tanggal 23 Juni 1983. Tujuan penelitian adalah untuk mempelajari pengaruh pertumbuhan akibat perbedaan cara pemberian ransum terhadap karkas dan komposisi karkas kelinci lokal jantan. Tiga puluh ekor kelinci lokal jantan dengan bobot awal. 520.9 sampai 651.3 gram digunakan dalam penelitian ini. Ternak ini dibagi menjadi tiga kelompok masing- masing 10 ekor. Kelompok pertama mendapat perlakuan pertumbuhan lambat (A), kelompok kedua mendapat perlakuan pertumbuhan lambat-cepat (B) dan kelompok ketiga mendapat perlakuan pertumbuhan cepat (C). Penelitian dilakukan enam minggu dengan masa pendahuluan 10 hari, dalam Rancangan Acak Lengkap. Pada akhir penelitian, semua kelinci dipotong dan karkasnya diuraikan menjadi urat daging, lemak, tulang dan daging (urat daging ditambah lemak). Analisis peragam (Co-variance) model Y = TaXb digunakan untuk mempelajari pengaruh perlakuan terhadap komposisi tubuh dan karkasnya. Rumus Huxley (1932) model YaXb digunakan untuk mempelajari pertumbuhan relatif bobot tubuh kosong, bobot karkas dan komponennya terhadap bobot potong, bobot tubuh kosong dan bobot karkas. ...

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.
