Judul: Kondisi Feses dan Pertambahan Bobot Badan Pedet Sapi Perah FH yang Diberi Perlakuan Jus Silase Jagung Secara Oral
Abstrak: Silase adalah produk hasil fermentasi an-aerob pakan berkadar air tinggi dalam kurun waktu tertentu. Jus silase adalah cairan yang dihasilkan dari silase. Tujuan penelitian ini adalah untuk mengevaluasi kondisi feses dan pertambahan bobot badan pedet sapi Friesian Holstein yang diberi jus silase jagung secara oral. Sebanyak 9 ekor pedet FH jantan dibagi menjadi tiga perlakuan, yaitu: ransum kontrol (P1), ransum yang mengandung antibiotik 50 mg kg-1 (P2), dan kontrol + jus silase 0.3% (P3). Rancangan percobaan yang digunakan adalah rancangan acak lengkap dan parameter yang diukur adalah kondisi feses dan pertambahan bobot badan. Data dianalisis dengan analisis ragam (ANOVA). Hasil penelitian menunjukkan bahwa dibandingkan perlakuan kontrol, perlakuan jus silase dan antibiotik cenderung meningkatkan konsistensi feses dan pertambahan bobot badan pedet. Dapat disimpulkan bahwa performa pedet membaik setelah diberi jus silase yang nilainya sebanding dengan antibiotik.

Judul: Konsumsi Bahan Kering dan Profil Darah Pedet Friesian Holstein (FH) yang Diberi Perlakuan Jus Silase
Abstrak: Profil darah merupakan salah satu indikator penentu status kesehatan, sehingga penting melakukan evaluasi terhadap profil darah. Tujuan dari penelitian ini adalah untuk mengukur konsumsi bahan kering serta mengevaluasi jumlah eritrosit, nilai hematokrit, konsentrasi hemoglobin, jumlah leukosit dan persentase diferensiasi leukosit (neutrofil dan limfosit). Sembilan ekor pedet jantan berumur satu bulan dengan rataan bobot badan 54.27 ± 4.33 kg secara acak diberi perlakuan yang berbeda, terdiri dari: ransum kontrol (P1), ransum yang mengandung antibiotik 50 mg/kg (P2), dan ransum kontrol + jus silase 0.3% (P3). Rancangan yang digunakan adalah rancangan acak lengkap (RAL) dan data yang didapatkan dianalisis menggunakan analisis of varian (ANOVA) kemudian data yang signifikan diuji lanjut menggunakan Least Significant Difference (LSD). Hasil penelitian menujukkan bahwa perlakuan tidak memberikan pengaruh nyata terhadap konsumsi bahan kering, jumlah eritrosit, jumlah leukosit, konsentrasi hemoglobin, nilai hematokrit dan persentase limfosit namun berpengaruh nyata terhadap persentase neutrofil. Pedet yang diberi jus silase memiliki persentase neutrofil yang sebanding dengan pedet yang diberi perlakuan antibiotik, dan lebih rendah dari pada pedet yang diberi perlakuan kontrol. Dapat disimpulkan bahwa perlakuan tidak memberikan pengaruh terhadap konsumsi bahan kering dan profil darah, kecuali pada persentase neutrofil.

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.
