Judul: Pengaruh tingkat pemberian tepung daun singkong terhadap koefisien cerna protein dan serat kasar serta bobot dan panjang usus halus, cecum colon pada kelinci persilangan
Abstrak: Penelitian ini dilakukan di Bagian Aneka Ternak milik Balai Penelitian Ternak, Bogor. Penelitian ini dilaksana- kan selama sembilan minggu dari tanggal 27 Februari sampai dengan tanggal 30 April 1984. Tujuan penelitian ini adalah untuk mengetahui koefi- sien cerna protein dan serat kasar tepung daun singkong serta pengaruhnya terhadap bobot dan panjang usus halus, cecum dan colon pada kelinci jantan dan betina persilang- an. Banyaknya tepung daun singkong yang digunakan sebesar 0, 10, 20, 30 dan 40 persen. Rancangan percobaan yang digunakan adalah Rancangan Acak Lengkap dengan pola Faktorial (2 x 5), jenis kelamin sebagai faktor pertama dan ransum sebagai faktor kedua. Untuk mengetahui tingkat beda nyata dipakai analisis sidik ragam. Hasil penelitian menunjukkan bahwa perlakuan berpe- ngaruh sangat nyata (P / 0.01) terhadap koefisien cerna protein, tetapi untuk koefisien cerna serat kasar tidak berpengaruh nyata. Ransum dengan tingkat 0% tepung daun singkong sangat nyata (P0.01) lebih tinggi koefisien cerna proteinnya dibandingkan dengan tingkat 20, 30 dan 40 persen tepung daun singkong. Ransum dengan tingkat 0 dan 10, 10 dan 20 serta 20, 30 dan 40 persen tepung daun singkong tidak me- nunjukkan adanya perbedaan yang nyata. Perlakuan tidak berpengaruh nyata terhadap panjang usus halus, cecum dan colon serta bobot cecum dan colon, tetapi untuk bobot usus halus sangat nyata (P 10.01) pengaruhnya. Ransum dengan tingkat 30 persen tepung daun singkong sangat nyata (P0.01) lebih tinggi bobotnya dibandingkan dengan tingkat 0, 10 dan 20 persen tepung daun singkong. Ransum dengan tingkat 30 dan 40 persen tepung daun singkong tidak menunjukkan adanya perbedaan yang nyata, begitu juga untuk 0, 10, 20 dan 40 persen tepung daun singkong....

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.
