Judul: Substitusi Bungkil Kedelai Dengan Limbah Udang Dalam Ransum Domba Lokal Jantan dan Efeknya terhadap Kadar Kolesterol Darah.
Abstrak: Limbah udang merupakan limbah dari industri pengolahan udang beku yang terdiri dari campuran kepala, kulit dan ekor serta udang yang rusak atau udang afkir. Limbah udang ini memiliki nilai protein dan serat kasar berupa khitin yang tinggi dimana khitin ini merupakan molekul yang dapat mengikat lemak dan membawanya keluar bersama feses. Dengan adanya pengikatan lemak oleh khitin, diharapkan kolesterol dalam darah akan menurun. Selain itu, penggunaan limbah udang dalam ransum ternak juga dapat dilakukan sebagai sumber protein pengganti bungkil kedelai.

Judul: Substitusi Tepung Ikan dengan Bungkil Kedelai Dalam Ransum Yang Mengandung Ampas teh (Camelia sinensis) Terhadap Performan Domba Lokal Jantan
Abstrak: The subtitution of soybean meal with fish meal is used to maximaze and increase the utilization of 70% tea waste, because soybean meal with fish meal contain the most balanced amino acid comparing with others feed component. The Experiment conducted in Small Ruminant Laboratory, Department of Animal Production Science, Faculty on Animal Science, Bogor Agricultural University, from November 2003 until January 2004. 20 Local Lamb with average body weight 20.87±1.8 kg were observed. The experiment design used Completely Randomized Design with five treatments and four replications. The treatments that were given are R1 (10% soybean meal, 0% fish meal), R2 (7.5% soybean meal, 2.5% fish meal), R3 (5% soybean meal, 5% fish meal), R4 (2.5% soybean meal, 7.5% fish meal), R5 (0% soybean meal, 10% fish meal). Data were analysed with ANOVA and followed by doubel Duncan (Steel and Torrie, 1993). The result of this research showed that treatments was not a significantly different affected on feed consumption based on dry matter, average weight gain, feed conversion and Income Over Feed Cost. The average of feed consumption based on dry matter was 978.42±16.52; 999.84±25.00; 1013.21±10.39; 1013.07±15.84; 1010.25±18.47 gram/ekor/hari, average weight gain was 81.35±27.01; 87.30±29.67; 99.21±27.87; 117.06±11.90; 97.22±20.87 gram/ekor/hari, average of feed conversion was 12.97±3.91; 12.89±5.74; 10.85±3.15; 8.71±0.87; 10.74±2.19 gram/ekor/hari. It is concluded that all treatments shown a good substitution 2.5% of soybean meal with 7.5% fish meal is tend to the best of all treatment, because have good feed consumption, average weight gain, feed conversion and Income O ver Feed Cost.

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.
