Judul: Pengaruh Pemberian Konsentrat Mengandung Frass terhadap Profil dan Metabolit Darah Kambing Jantan Persilangan
Abstrak: Penelitian ini bertujuan untuk membandingkan pemberian konsentrat mengandung frass dan konsentrat komersial lakto dengan mengevaluasi profil dan metabolit darah kambing jantan persilangan. Penelitian menggunakan delapan ekor kambing jantan persilangan dengan rataan bobot badan awal 21 ± 1.4 kg yang dibagi menjadi dua jenis perlakuan dengan empat ulangan. Perlakuan terdiri atas pemberian konsentrat mengandung lakto (P1) dan pemberian konsentrat mengandung frass (P2). Peubah yang diukur meliputi hemoglobin, hematokrit, eritrosit, leukosit, differensiasi leukosit, total protein darah, kolesterol darah dan konsumsi zat makanan. Analisis data menggunakan uji Independent Sample t-test. Hasil menunjukkan bahwa pemberian konsentrat mengandung frass tidak berbeda nyata dengan pemberian konsentrat yang mengandung lakto terhadap hemoglobin, hematokrit, eritrosit, leukosit, differensiasi leukosit, total protein darah, kolesterol darah dan konsumsi zat makanan kambing jantan penelitian. hemoglobin, hematokrit, eritrosit, leukosit, differensiasi leukosit, total protein darah, kolesterol darah dan konsumsi zat makanan pada kambing jantan penelitian masih memiliki nilai yang mencakupi standar normal. Ransum dengan konsentrat frass dapat dijadikan sebagai ransum alternatif.

Judul: Profil dan Metabolit Darah pada Kerbau Calon Induk yang Diberi Konsentrat Flushing.
Abstrak: Flushing merupakan metode pemberian pakan dengan energi tinggi yang dapat membantu meningkatkan kinerja reproduksi ternak. Tujuan penelitian ini adalah untuk menganalisis hematologi dan metabolit darah pada kerbau betina calon induk yang diberi konsentrat flushing. Penelitian dilakukan selama tiga puluh hari dan menggunakan enam ekor kerbau betina calon induk yang dibagi menjadi dua kelompok, yaitu P1= pakan hijauan (kontrol) dan P2= P1 + 1kg konsentrat flushing. Peubah yang diamati antara lain hematologi darah yang meliputi hemoglobin, hematokrit, neutrofil, eosinofil, basofil, limfosit dan monosit, serta metabolit darah yang meliputi glukosa darah, kolesterol darah, protein total dan albumin. Analisis data terhadap peubah yang diamati menggunakan uji-T sebagai pembanding hasil. Hasil penelitian menunjukkan bahwa pemberian konsentrat flushing pada kerbau betina calon induk tidak berpengaruh terhadap metabolit darah. Konsentrat flushing dapat memperbaiki kadar hemoglobin dan hematokrit pada kerbau calon induk, sehingga berada dalam kisaran normal. Hal ini dapat meningkatkan nutrient pakan yang terangkut menuju jaringan tubuh. Kadar neutrofil yang lebih tinggi dan limfosit yang lebih rendah pada P2, menunjukkan bahwa ternak mengalami stres. Kadar eosinofil pada kedua perlakuan berada di atas kisaran normal yang dapat disebabkan oleh manajemen pemeliharaan.

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.
