Judul: Penguji cobaan bahan limbah rumah potong hewan (RPH) dan ragi makanan ternak (RMT) serta kombinasinya dalam ransum ayam pedaging
Abstrak: Tujuan penelitian ini adalah untuk mengetahui pengaruh penggunaan isi rumen sapi, isi rumen domba, dan ragi makanan ternak secara tersendiri maupun kombinasinya dalam ransum ayam pedaging terhadap pertambahan bobot badan, konsumsi ransum, konversi ransum, efisiensi ransum, daya cerna protein, dan "protein Effisiensi ratio". Selain itu dilakukan pula tes uji rasa daging, juga pengamatan terhadap mortalitas dan tinjauan ekonominya. Dalam penelitian digunakan 336 ekor anak ayam pedaging umur satu hari, jenis GP 707 "final stock" yang terdiri dari 168 ekor jantan dan 168 ekor betina. Selama penelitian ayam-ayam tersebut dipelihara dalam boks beralaskan kawat yang berukuran 90 x 60 x 30 cm untuk periode pemula, dan ukuran 80 x 80 x 40 cm untuk periode ahkir.

Judul: Penggunaan Manure Ayam Dan Domba Dalam ransum Ayam Untuk Produksi daging
Abstrak: Penelitian untuk mempelajari pengaruh penggunaan manu- re ayam dan domba sebagai bahan campuran dari ransum ayam petelur jantan, telah dilakukan di Fakultas Peternakan, Ing titut Pertanian Bogor dari tanggal 23 Desember 1982 sampai dengan tanggal 13 Maret 1983. Dalam penelitian ini dipergunakan 200 ekor anak ayam petelur jantan strain Hy-Line umur satu hari yang dipeliha- ra dalam kandang beralas dan berdinding kawat berukuran 1 x 1 x 0.5 m, dengan kepadatan 10 ekor per meter persegi. Penelitian ini dilakukan dengan empat perlakuan dan lima ulangan, setiap ulangan terdiri atas 10 ekor anak ayam. Keempat perlakuan tersebut adalah pemberian ransum dengan persen manure (Ro), pemberian ransum yang ditambah 10 per sen manure ayam (R₁), pemberian ransum yang ditambah 10 per sen manure domba (R) dan pemberian ransum yang ditambah 5 persen manure ayam dan 5 persen manure domba (R₂). Ransum dan air minum diberikan diberikan secara ad libitum. Ranca ngan Acak Lengkap digunakan untuk mengetahui pertumbuhan, konsumsi dan konversi ransum. Setelah ayam berumur 10 ming gu dari setiap perlakuan masing-masing diambil secara acak 10 ekor ayam. Untuk mengetahui pengaruh perlakuan terhadap bobot irisan komersial, bobot distribusi tulang dan bagian yang dapat dikonsumsi dari setiap irisan komersial, bobot organ tubuh, serta bobot lemak rongga tubuh dan bobot thy- mus, dilakukan seksi dan hasilnya diolah menurut analisis peragam (Covariance) model Y T₁ a X....

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.
