Judul: Pengaruh kombinasi dynamutilin dengan quixalud terhadap berat organ internal dan alat pencernaan anak babi
Abstrak: Tujuan penelitian adalah untuk mengetahui pengaruh kombinasi dynamutilin dengan quixalud terhadap berat organ internal dan alat pencernaan, tebal usus, panjang usus pada anak babi. Anak babi yang digunakan berumur 2 bulan, berat badan rata-rata adalah (8,04 -+ 1,17) kg. Percobaan dengan rancangan acak lengkap yang terdiri dari tiga fase, dengan ransum sebagai berikut: Pada fase I ransum A adalah sebagai kontrol (tanpa perlakuan) B adalah ransum dengan kadar 20 ppm dynamutilin dan 120 ppm quixalud C ransum dengan kadar 20 ppm dynamutilin dan 40 ppm quixalud dan D dengan kadar 20 ppm dynamutilin dan 120 ppm quixalud. Pada fase II ransum D dengan 10 ppm dynamutilin dan 60 ppm quixalud. Pada fase III perlakuan dihentikan.

Judul: Pengaruh kombinasi dynamutilin dan quixalud terhadap komposisi karkas berbagai jenis kelamin anak babi
Abstrak: Tujuan penelitian adalah untuk melihat perbedaan berbagai dosis kombinasi dynamutiliru dan quixalud sebagai makanan tambahan terhadap komposisi karkas berbagai jenis kelamin anak babi. Kriteria yang dipakai untuk pengukurannya adalah “dressing percentage”, persentase karkas, panjang, karkas, tebal lemak punggung, luas otot longissimus sacralis, persentase lemak, persentase daging dan persentase tulang. Data komposisi karkas didapat dari 16 ekor babi yang dipotong yang terdiri dari 8 ekor jantan, 4 ekor betina dan 4 ekor kastrasi. Hasil penelitian memperlihatkan bahwa pemberian kombinasi dynamutilin dan, quixalud secara keseluruhan tidak nyata dapat meningkatkan panjang karkas, tebal lemak punggung, luas otot longissimus sacralis dan persentase lemak, dan sebaliknya menurunkan sedikit persentase daging, persentase tulang dan “dressing percentage”. Sedangkan persentase karkas hampir sama antara babi yang diberikan kombinasi dynamutilin dan quixalud dengan kontrol.

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.
