Judul: Efisiensi dan Kecernaan Serat Ransum Mengandung Limbah Tauge Pada Kelinci Lokal Jantan Masa Pertumbuhan
Abstrak: Kelinci merupakan ternak sumber protein hewani yang dapat berpeluang sebagai produk unggulan di sektor peternakan. Kebutuhan kualitas nutrisi yang bagus pada pakan kelinci sudah tersedia pada pakan komersil namun ransum komersil untuk kelinci yang ada di pasaran cenderung mempunyai harga yang mahal sehingga diperlukan alternatif untuk mencari pakan yang tersedia secara kontinu, memiliki nilai gizi yg cukup, mudah dicerna, dan murah seperti limbah tauge. Limbah tauge merupakan sisa produksi tauge yang terdiri dari kulit kacang hijau dan pecahan-pecahan tauge. Penelitian ini bertujuan untuk mengetahui performa dan kecernaan komponen serat dalam ransum komplit campuran limbah tauge dengan level pemberian limbah tauge yang berbeda pada kelinci lokal jantan masa pertumbuhan. Rancangan yang digunakan dalam penelitian ini adalah Rancangan Acak Kelompok (RAK) dengan uji lanjut Duncan yang terdiri dari 4 perlakuan 3 ulangan masing-masing ulangan terdiri dari 1 ekor kelinci Lokal jantan. Perlakuan yang digunakan yaitu P0 (100% ransum komersil), P1, P2, dan P3 (masing-masing terdiri dari ransum komersil 85%, 70%, dan 55%, penambahan limbah tauge masing-masing 15%, 30% dan 45%). Peubah yang digunakan dalam penelitian adalah konsumsi bahan kering, pertambahan bobot badan harian, efisiensi pakan, kecernaan serat kasar (SK), kecernaan Neutral Detergent Fiber (NDF), dan kecernaan Acid Detergent Fiber (ADF).

Judul: Performa Produksi Kelinci Lokal Jantan Muda dengan Pemberian Campuran Pellet Komersil dan Limbah Tauge
Abstrak: Kelinci (Orictolagus cuniculus) berpotensi besar sebagai penghasil daging karena sifatnya yang prolifik, pertumbuhannya cepat, dan dapat memanfaatkan limbah pertanian sebagai pakan. Limbah tauge merupakan limbah pasar yang kandungan nutrisinya yang masih baik sehingga dapat digunakan sebagai pakan. Tujuan dari penelitian ini adalah mengamati performa produksi kelinci lokal jantan muda yang diberi limbah tauge. Sebanyak 12 ekor kelinci lokal jantan muda dengan kisaran umur 12 minggu dan rataan bobot badan 747±104.53 g digunakan dalam penelitian ini. Tiga perlakuan pakan yang diberikan yaitu P0 berupa 100% pellet komersil, P1 berupa 30% limbah tauge dan 70% pellet komersil, serta P2 berupa 50% limbah tauge dan 50% pellet komersil. Hasil analisis ragam menunjukkan bahwa perbedaan perlakuan pakan tidak berpengaruh terhadap konsumsi bahan kering, protein kasar, TDN dan pertambahan bobot badan. Sehingga dapat disimpulkan bahwa limbah tauge segar dapat dijadikan sebagai substitusi pakan kelinci hingga taraf 50% tanpa menurunkan performa produksinya.

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.
