Judul: Suplementasi Ginseng Liar (Wild ginseng) pada Ransum Terhadap Pertumbuhan Mencit (Mus musculus)
Abstrak: The aim of the research was to know effectiveness of supplementation of wild ginseng on growth of male and female mouse (Mus musculus). This research used completely randomized design with four treatments and six replications and used one mouse for each replication. The diet treatments were R1 = control diet (without ginseng), R2 = R1+0.0134% ginseng, R3 = R1+0.026% ginseng and R4 = R1+0.04% ginseng. The parameters measured were, dry matter intake, organic matter intake, crude protein intake, crude fiber intake, body weight gain, feed convertion and mortality. Data were analyzed with analyse of variance (ANOVA) and significant differences were further tested using orthogonal contrast test. The results showed that the treatments did not significantly affect (P>0.05) to dry matter intake, organic matter intake, crude protein intake, body weight gain, feed convertion and mortality except to crude fiber intake (P<0,01) which significantly affected.

Judul: PEngaruh Akar Gingseng (Wild ginseng) dalam Ransum Mencit (Mus musculus) terhadap Jumlah Anak dan Pertumbuhan Anak dari Lahir sampai dengan Sapih
Abstrak: Ginseng merupakan tanaman herbal alami yang memiliki bahan aktif flavonoid dan ginsenosid yang bermanfaat dalam memelihara diri dari penyakit, meningkatkan daya tahan tubuh dan merangsang pembentukan hormon estrogen pada mamalia. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh akar ginseng terhadap jumlah anak dan pertumbuhan anak mencit dari lahir sampai dengan sapih. Penelitian ini dilaksanakan sejak Juli sampai dengan September 2005 di kandang A Fakultas Peternakan, Institut Pertanian Bogor. Mencit yang digunakan adalah mencit yang sudah dewasa tubuh berumur dua bulan sebanyak 48 ekor masing-masing 24 ekor betina dan 24 ekor jantan. Perkawinan dilakukan dengan perbandingan satu jantan dengan satu betina yang dimasukkan ke dalam kandang kawin. Rancangan yang digunakan adalah rancangan acak lengkap (RAL) dengan empat taraf perlakuan yaitu R1 (kontrol), R2 (0.0134 % ginseng), R3 (0.026 % ginseng), dan R4 (0.04 % ginseng). Data dianalisis dengan sidik ragam (Anova), jika berbeda nyata maka dilanjutkan dengan uji Duncan. Peubah yang diamati adalah jumlah anak per kelahiran, bobot lahir, pertambahan bobot badan anak dan bobot sapih.

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.
