Judul: Optimalisasi penggemukan kelinci muda untuk produksi fryer dengan pemberian konsentrat dalam jumlah yang berbeda
Abstrak: Produksi kelinci muda potong (fryer) dilaksanakan dengan penggemukan kelinci sapihan sampai mencapai bobot 1700 g. Penggemukan dilakukan dengan cara pemberian pakan penguat pada tiga level (60, 80 dan 100 g) ditambah rumput lapangan ad libitum. Tujuannya adalah untuk mengetahui pada level berapa yang paling optimal dalam penggemukan kelinci. Penelitian dilakuakan di Bagian Ilmu Produksi Ternak Ruminansia Kecil, Fakultas Peternakan, Institut Pertanian Bogor, dari bulan Februari sampai Juni 2005. Materi yang digunakan sebanyak 21 ekor ternak kelinci lepas sapih yang terdiri dari 15 ekor jantan dan 6 ekor betina, dengan bobot hidup antara 575-1065 g; koefisien keragaman (kk) = 20,70%. Konsentrat diproduksi oleh PT. Universal Agri Bisnisindo dengan kandungan nutrisi antara lain: kadar air, protein kasar, lemak kasar, serat kasar, abu, Ca, P dan TDN masing-masing adalah: 13,0; 14,0; 3,0; 7,0; 14,0; 3,3-4,0; 0,6-0,8 dan 56,47% diberikan dengan perbandingan yang berbeda. Rumput lapangan diberiakn secara ad libitum pada semua perlakuan dengan kandungan nutrisi antara lain kadar air, protein kasar, lemak kasar, serat kasar, abu, Ca, P dan TDN masing- masing adalah 76,5; 8,82; 1,46; 32,5; 14,3; 0,40; 0,25 dan 49,13%. Kelinci diacak kedalam tiga kelompok (A, B dan C) perlakuan, tiap perlakuan mempunyai tujuh ulangan. Rancangan yang digunakan adalah Rancangan Acak Lengkap (RAL) dan Analisis Kovarian. Pada akhir penelitian semua ternak dipotong dan diuraikan karkasnya berdasarkan potongan komersial.

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.
