Judul: Kualitas Daging Babi dengan Pemberian Zeolit dan Tepung Darah sebagai Sumber Protein dalam Ransum
Abstrak: Daging babi sebagai produk akhir dari pemeliharaan ternak babi penting untuk diperhatikan kualitasnya. Konsumen sekarang cenderung semakin selektif dalam memilih daging. Pemilihan daging babi yang berkualitas biasanya akan memperhatikan beberapa karakteristik daging yang dijadikan pegangan antara lain warna, tumpukan, daya mengikat air, dan lemak intramuskuler. Usaha peningkatan kualitas daging babi tidak terlepas dari ransum yang diberikan pada ternak tersebut selama pertumbuhannya, akan tetapi biaya bahan ransum yang lazim relatif mahal dan merupakan biaya terbesar dari usaha ternak babi. Penggunaan bahan ransum alternatif yang tidak bersaing dengan kebutuhan manusia, baik sebagai sumber protein maupun mineral, dan menyusun komposisi ransum dengan taraf yang tepat adalah usaha meminimumkan biaya tersebut dan untuk mendapatkan keuntungan yang maksimum.

Judul: Pengaruh taraf pemberian protein dan zeolit dalam ransum terhadap penampilan ternak babi periode bertumbuh-pengakhiran
Abstrak: Penelitian dilakukan di kandang ternak babi Jurusan Ilmu Produksi Ternak, Fakultas Peternakan, Institut Perta- nian Bogor selama 14 minggu dari tanggal 9 Nopember 1992 sampai dengan 28 Pebruari 1993. Tujuan penelitian ini adalah untuk mengetahui penga- ruh dari taraf protein dan zeolit dalam ransum terhadap penampilan ternak babi bertumbuh-pengakhiran dengan meli- hat konsumsi ransum, pertambahan berat badan, efisiensi penggunaan makanan, dan mengetahui apakah zeolit dapat mengefisiensikan penggunaan protein ransum dilihat dari kadar air dan protein kotoran. Ternak babi yang digunakan selama penelitian sebanyak 24 ekor babi Landrace terdiri dari 12 ekor betina dan 12 ekor jantan dengan rataan bobot awal 43,90 ± 5,41 kg. Ransum penelitian terdiri dari delapan macam yaitu R1 (13% protein, 0% zeolit), R2 (13% protein, 3% zeolit), R3 (13% protein, 6% zeolit), R4 (13% protein, 9% zeolit), R5 (15% protein, 0% zeolit), R6 (15% protein, 3% zeolit), R7 (15% protein, 6% zeolit) dan R8 (15% protein, 9% zeolit) Rancangan penelitian yang digunakan adalah rancangan acak lengkap pola faktorial 2x4 dengan tiga ulangan. Hasil penelitian menunjukkan bahwa pengaruh perlakuan taraf zeolit, protein dan interaksinya tidak berbeda nyata terhadap konsumsi ransum, pertambahan berat badan, efisi- ensi penggunaan makanan, kadar air kotoran dan kadar protein kotoran. Ransum dengan pemberian sembilan persen zeolit mem- perlihatkan konsumsi ransum, pertambahan berat badan, yang lebih tinggi; efisiensi penggunaan makanan (feed/gain), kadar air kotoran, protein kotoran yang lebih rendah. Ransum tanpa pemberian zeolit dengan 13% protein memberikan nilai ekonomis yang paling baik, hal ini ditun- jukkan dengan pendapatan yang diperoleh paling tinggi.

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.
