Judul: Performa dan Kecernaan Nutrien pada Domba yang diberi Tepung Daun Singkong Pahit (Manihot Esculenta) dan Bakteri Pendegradasi Hcn.
Abstrak: Penelitian ini bertujuan untuk menganalisis pemberian tepung daun singkong pada performa domba dan kecernaan nutrien. Rancangan percobaan yang digunakan rancangan acak kelompok (RAK) 5x3 menggunakan 15 ekor domba jantan, umur sekitar 12 bulan dengan bobot badan 18.76 ± 1.02 kg dan ditempatkan di kandang individu. Perlakuan dalam penelitian ini adalah P1= 40% rumput gajah: 60% konsentrat, P2= kontrol+15% tepung daun singkong, P3= kontrol+15% tepung daun singkong + inokulan , P4= kontrol+30% tepung daun singkong, P5 = kontrol+30% tepung daun singkong + inokulan. Data dianalisis menggunakan analisis of varian (ANOVA). Hasil penelitian menunjukkan bahwa penggunaan 30% tepung daun singkong tidak mengurangi konsumsi nutrien dan kecernaan nutrien dibandingkan dengan kontrol. Pemberian 15% tepung daun singkong dan penambahan bakteri pendegradasi HCN nyata pengaruhnya (P <0.05) terhadap pertambahan bobot badan dan efisiensi pakan. Dapat disimpulkan bahwa perlakuan yang diberikan dapat meningkatkan bobot badan dan efisiensi pakan.

Judul: Performa Domba Dengan Pakan Daun Singkong Pahit (Manihot Esculenta Crantz) Dan Enkapsulasi Bakteri Pendegradasi Sianida.
Abstrak: Penelitian ini bertujuan menganalisis pengaruh enkapsulasi inokulan bakteri pendegradasi sianida terhadap performa domba meliputi konsumsi bahan kering, pertumbuhan bobot badan harian, efisiensi pakan dan income over feed cost (IOFC) pada domba yang diberikan pakan tepung daun singkong pahit (Manihot esculenta Crantz). Sebanyak 12 ekor domba jantan, berumur ± 1-1.5 tahun dengan rataan bobot badan awal 16 ± 1.56 kg digunakan dalam percobaan ini dan dipelihara pada kandang individual. Rancangan percobaan yang digunakan adalah rancangan acak kelompok (RAK) dengan 3 perlakuan 4 kelompok sebagai ulangan. Pengelompokkan domba berdasarkan bobot badan awal. Perlakuan dalam penelitian ini adalah P0 = rumput gajah (RG) (60%) : konsentrat (K) (40%); P1 = RG (60%) : K (25%) : tepung daun singkong (TDS) (15%); P2 = P1 + enkapsulasi inokulan bakteri pendegradasi sianida (EIBPS). Data dianalisis menggunakan analysis of variance (ANOVA). Hasil penelitian menunjukkan bahwa penambahan EIBPS pada ransum domba yang mengandung 15% TDS tidak mempengaruhi (P>0.05) konsumsi bahan kering, pertambahan bobot badan harian, efisiensi pakan dan nilai Income Over Feed Cost (IOFC) domba. Dapat disimpulkan bahwa penambahan EIBPS pada ransum domba yang diberi pakan mengandung TDS 15% tidak mempengaruhi performa 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.
