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: Evaluasi Kualitas Pellet Ransum Komplit yang Mengandung Limbah Udang Hidrolisat dan Pemanfaatannya pada Ternak Domba
Abstrak: Limbah udang merupakan limbah industri pengolahan udang beku berupa kepala, ekor, dan kulit udang, serta udang yang rusak atau afkir (Mirzah 2007). Bila ditinjau dari segi kuantitas dan kualitas, limbah udang sangat potensial dijadikan pakan ternak. Sebagai gambaran, pada Tahun 2008 produksi udang Indonesia sebesar 470.000 ton (DKP 2009), bila diolah menjadi udang beku maka limbah udang yang diperoleh sebesar 35 sampai dengan 70% dari bobot utuh (Mahata 2007) yaitu setara dengan 164.500 sampai dengan 329.000 ton basah atau 41.010 sampai dengan 82.020 ton kering karena rendemennya 24.93% (Batubara 2000). Jadi secara kuantitas, tersedia cukup banyak dan kesinambungannya cukup terjamin karena setiap tahun produksi udang Indonesia selalu mengalami peningkatan. Ditinjau dari segi kualitas, limbah udang mengandung protein kasar sebesar 36.75% (Mirzah 2006). Selain itu, juga mengandung kitin berupa senyawa polisakarida struktural (mirip selulosa) sebesar 30% dari bahan keringnya (Purwaningsih 2000) yang mengikat nitrogen dalam bentuk N-Acetylatedglucosamin- polysacharida sebanyak 6.6 sampai dengan 6.7% (Stelmoch et al. 1985). Penggunaan limbah udang sebagai pakan ternak sampai saat ini masih terbatas pada ternak non-ruminansia. Oleh karena itu perlu dicoba pada ternak ruminansia. Tujuan penelitian adalah mengevaluasi kualitas kimia dan fisik pellet ransum komplit yang mengandung hidrolisat limbah udang dan mengevaluasi pengaruh pemberian pellet ransum komplit yang mengandung limbah udang pada performa ternak domba.

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.
