Judul: Pegaruh Pemberian Gula Pasir dan Vitamin C pada Ternak Domba Sebelum Pengangkutan Terhadap Status Faal, Penyusutan Bobot Badan dan Profil Darah saat Transportasi
Abstrak: Tujuan dari penelitian ini adalah untuk mengetahui pengaruh pemberian gula pasir dan vitamin C dalam transportasi hewan ternak untuk mengurangi tingkat stres pada domba. Penelitian ini menggunakan rancangan acak lengkap dengan 3 perlakuan yaitu P1 (Kontrol), P2 (Vitamin C 125 mg kg-1 BB), P3 (Gula Pasir 6 g kg-1 BB) dan 3 ulangan setiap perlakuan. Variable yang dihitung antara lain bobot badan, respirasi, suhu rektal, detak jantung, dan analisis profil darah. Data diolah menggunakan analysis of variance (ANOVA), apabila terdapat perbedaan yang nyata. Dari hasil penelitian pemberian vitamin C pada domba mampu menurunkan stres selama transportasi yang berakibat pada penyusutan bobot badan domba. Penyusutan berat badan domba dengan pemberian vitamin C berhasil mencapai angka 9.95±0.72 kg, lebih rendah dari penyusutan bobot badan domba perlakuan lainnya yaitu pemberian gula yang mencapai 8.58±2.67 kg dan perlakuan control yaitu sebesar 10.92±2.55 kg.

Judul: Profil Darah, Respon Fisiologis, dan Performa Domba Lokal Pascatransportasi Dengan Suplementasi Asam Amino dan Gula
Abstrak: Transportasi dapat menyebabkan stres yang berdampak terhadap penyusutan bobot badan dan perubahan kondisi fisilogis domba. Penelitian ini bertujuan untuk mengkaji perubahan profil darah, respon fisiologis dan performa domba lokal pascatransportasi darat yang diberi penambahan asam amino dan gula. Percobaan ini dilaksanakan di Blok B, Laboratorium Lapangan Fakultas Peternakan, IPB. Penelitian berlangsung pada bulan September 2021 menggunakan domba lokal jantan dengan kisaran bobot 20,91 ± 2,73 kg. Perlakuan berupa pemberian asam amino 12 g ekor-1 dan gula sebanyak 25 g ekor-1 perhari dengan cara dicampurkan dalam ransum. Model perlakuan yaitu P0 = Kontrol (tanpa penambahan asam amino dan gula), P1 = dengan penambahan asam amino dan gula, masing-masing mendapat empat ulangan. Perlakuan ini diterapkan selama pemeliharaan 15 hari sebelum pengangkutan dan masa recovery hingga mencapai bobot semula. Transportasi dilakukan selama ± 8 jam pada siang hari, dengan luasan dek selama transportasi sebesar 0,1 m2 ekor-1. Data dianalisis menggunakan uji T antara kontrol dan perlakuan. Hasil penelitian menunjukkan bahwa pemberian asam amino dan gula tidak mempengaruhi variable yang diamati (P>0,05).

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.
