Judul: Pertumbuhan mencit (Mus musculus) yang diberi beberapa taraf tepung lengkuas (Alpinia galanga L. Swartz) dalam ransum
Abstrak: Lengkuas merupakan salah satu tanaman obat yang mempunyai banyak manfaat seperti antiseptik, antimikroba dan antioksidan. sebagai tanaman obat, lengkuas dapat digunakan untuk menguatkan lambung dan meningkatkan pencernaan. Tujuan penelitian ini untuk mengetahui respon pertumbuhan mencit yang diberi tambahan tepung lengkuas dan ransum. Mencit yang digunakan sebanyak 72 ekor mencit lepas sapih yang terdiri atas 36 jantan dan 36 betina. Parameter yang diamati yaitu konsumsi ransum, konsumsi air minum, pertambahan bobot badan, konversi ransum dan mortalitas.

Judul: Performa mencit, Mus musculus jantan dan betina dengan suplementasi tepung temulawak, (Curcuma xanthorrhiza Roxb) dalam ransum
Abstrak: Feed additive dapat meningkatkan nilai guna, namun perlu diketahui keamanan penggunaan feed additive terhadap ternak, sehingga perlu digunakan hewan percobaan sebelum diaplikasikan pada ternak. Mencit sering digunakan sebagai hewan percobaan karena mudah ditangani, memiliki sifat produksi dan reproduksi yang tinggi dan menyerupai mamalia. Temulawak (Curcuma xanthorrhiza Roxb.) dapat digunakan sebagai feed additive karena dianggap berkhasiat menambah nafsu makan, sebagai antioksidan dan meningkatkan sekresi empedu.. Penelitian dilakukan sejak tanggal 2 Agustus sampai dengan 26 September 2005, bertempat di Laboratorium Lapang C, Bagian Non Ruminansia dan Satwa Harapan, Departemen Ilmu Produksi dan Teknologi Peternakan, Fakultas Peternakan, Institut Pertanian Bogor. Tujuan penelitian ini adalah mendapatkan persentase suplementasi tepung temulawak yang terbaik terhadap konsumsi ransum, pertambahan bobot badan (PBB), konversi pakan, dan mortalitas. Materi penelitian yang digunakan adalah 96 ekor (48 ekor jantan dan betina) mencit umur 21 hari yang diperoleh dari Laboratorium Lapang C, Bagian Non Ruminansia dan Satwa Harapan. Rancangan percobaan yang digunakan adalah Rancangan Acak Lengkap (RAL) pola faktorial 4 x 2 dengan empat ulangan. Faktor pertama yaitu jenis pakan yang terdiri dari P1 (100% ransum DOC +0% tepung temulawak), P2 (100% ransum DOC 5% tepung temulawak), P3 (100% ransum DOC + 10% tepung temulawak), dan P4 (100% ransum DOC + 15% tepung temulawak) dan faktor kedua yaitu jenis kelamin (jantan dan betina). Peubah yang diamati yaitu pertambahan bobot badan (PBB), konsumsi ransum, konversi pakan, dan mortalitas. Data yang diperoleh dianalisa dengan sidik ragam (ANOVA), jika perlakuan berpengaruh nyata terhadap peubah yang diamati maka dilanjutkan dengan uji lanjut Duncan untuk mengetahui perbedaan diantara perlakuan tersebut. Hasil penelitian menunjukkan, bahwa suplementasi tepung temulawak dengan taraf 5% menghasilkan performa terbaik terhadap mencit. Mencit jantan memiliki performa lebih baik dibandingkan dengan mencit betina.

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.
