Judul: Persentase Karkas, Saluran Pencernaan dan Organ Dalam Kelinci Jantan Lepas Sapih Dengan Subtitusi Tepung Ikan dan Bungkil Kedelai Dalam Ransum Mengandung Ampas Teh (Camellia sinensis)
Abstrak: Salah satu limbah industri yang dapat dijadikan pakan alternatif adalah ampas teh. Berdasarkan analisis laboratorium, bahan ini mempunyai kadar protein dan serat kasar yang tinggi yaitu 27 % dan 20.39 %. Bahan ini dicobakan pada kelinci. Penelitian telah dilakukan di Kandang B Laboratorium Ruminansia Kecil, Departemen llmu Produksi Ternak, Fakultas Peternakan. lnstitut Peternakan Bogor. Pelaksanaannya mulai Juni - Agustus 2003. Jumlah ternak adalah 30 ekor kelinci jantan lepas sapih dengan bobot hidup awal 315 * 18 gram.Tujuannya adalah untuk mempelajari level terbaik subtitusi tepung ikan dengan bungkil kedelai dalam ransum kelinci dengan penggunaan ampas teh dan konsentrat (jagung, dedak padi, pollard, minyak sayur, molasses, premix dan CaC03) terhadap bobot potong, %tase karkas, saluran pencernaan, organ dalam dan konsumsi air minum. Rancangan percobaan yang digunakan adalah Rancangan Acak Lengkap (RAL) dengan 5 perlakuan dan 4 ulangan. Perlakuan yang diberikan adalah R1 (10 % bungkil kedelai, 0 % tepung ikan) ; R2 (7,5 % bungkil kedelai, 2,5 % tepung ikan) ; R3 (5 % bungkil kedelai, 5 % tepung ikan) ; R4 (2,5 % bungkil kedelai, 7,s % tepung ikan) ; dan R5 ( 0 % bungkil kedelai, 10 % tepung ikan). Semua ransum penelitian mempunyai kadar ampas tel: 50 %. Hasil penelitian ini menunjukkan ransum perlakuan tidak mempunyai pengaruh yang nyata terhadap bobot karkas, saluran pencernaan dan organ dalam. Hasil yang baik ditunjukkan oleh perlakuan R1 yaitu pemberian 10 % bungkil kedelai, karena tanpa pemberian tepung ikan dapat menghasilkan karkas 50 %. Berdasarkan hasil penelitian ini subtitusi antara bungkil kedelai dan tepung ikan tidak diperlukan karena tanpa pemberian tepung ikan bobot karkas yang dihasilkan selam 10 minggu penelitian mencapai 50 %, selain itu harganya paling murah.

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.
