Judul: Pengaruh Bahan Makanan Sumber Karbohidrat Dengan Tingkat Protein Yang Berbeda Terhadap Penampilan Produksi ternak Kelinci Jantan Persilangan
Abstrak: Pemanfaatan konsentrat sebagai bahan makanan ternak kelinci sampai saat ini belum banyak dilakukan. Hal ini di- sebabkan sulitnya pencampuran dan pengolahan lebih lanjut menjadi pellet. Padahal konsentrat kaya akan protein dan energi yang sangat dibutuhkan oleh kelinci. Tujuan dari percobaan ini adalah untuk mengetahui pe- ngaruh pemberian beberapa tingkat protein dengan sumber karbohidrat yang berbeda dalam ransum konsentrat terhadap konsumsi bahan kering, penaikan bobot badan dan efisiensi penggunaan ransum pada ternak kelinci jantan persilangan. Di dalam percobaan ini digunakan 36 ekor kelinci jan- tan hasil persilangan dengan bobot hidup 700 1950 gram - yang dibagi ke dalam 6 kelompok berdasarkan bobot hidupnya tersebut sebagai ulangan dengan 6 macam kombinasi ransum yang mempunyai 3 tingkat protein (12, 14 dan 16%) pada tingkat energi 3500 - bohidrat yang berbeda. 3600 kcal/kg dan 2 macam sumber kar- Berdasarkan uji statistik ternyata tingkat protein di- dalam ransum berpengaruh sangat nyata terhadap penaikan bo- bot badan dan efisiensi penggunaan bahan kering ransum oleh kelinci (P<0.01) dan cenderung meningkatkan konsumsi bahan kering ransumnya. Sedangkan sumber karbohidrat berdasarkan uji statistik berpengaruh nyata terhadap penaikan bobot badan dan efisi- ensi penggunaan bahan kering ransumnya (P<0.05). Dari hasil perhitungan regresi terlihat hubungan yang erat antara tingkat protein ransum dengan konsumsi bahan kering, penaikan bobot badan dan efisiensi penggunaan bahan kering ransumnya, dimana makin tinggi tingkat protein dalam ransum diikuti oleh peningkatan konsumsi bahan kering, pe- naikan bobot badan dan efisiensi penggunaan bahan keringnya.

Judul: Pengaruh perbedaan kandungan serat kasar ransum terhadap penampilan produksi kelinci persilangan jantan
Abstrak: Dalam usaha meningkatkan penyediaan daging untuk meningkatkan gizi masyarakat, kelinci merupakan jenis ternak yang cukup potensial untuk dikembangkan. Kelinci dapat berkembangbiak dan mampu menggunakan lebih banyak proporsi hijauan dalam ransumnya. Kandungan serat kasar akan menentukan keefisienan penggunaan ransum. Semakin tinggi kandungan serat kasar, koefisien cerna dan keefisienan ransum semakin rendah. Bagi kelinci, serat kasar mempunyai nilai gizi yang rendah, tetapi dalam jumlah tertentu tetap dibutuhkan di dalam ransumnya. Hal ini mengingat fungsi serat kasar sebagai "bulk", sumber energi dan zat laksan.

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.
