Judul: Reproduksi mencit (Mus musculus) yang diberi pakan mengandung protein sel tunggal sebagai pengganti tepung daging dan tulang dalam ransum
Abstrak: This researclx was conducted to study the effects of Single Cell Protein (SCP) as substitutes of Meat and Bone Meal (MBM) on the reproduction of mice. A total of 50 mice which divided into 25 units, each units consist of a co~~polef male and female were used. This study used Randomized Comp1e:e Design consist is 5 tretments and 5 replicates. T!le treatment were : 1) R1 (6% MBM and 0% SCP), 2) R2 (4,5% MBM and 1,5% SCP), 3) R3 (3% MBM and 3% SCP), 4) R4 (1,5% MBM and 4,5% SCP) and 5) R5 (0% MBM and 6% SCP). Feed and water was given ad libiturn. The results showed that treatment were signivicantly (P<0.01) affect feed intake of dams and childs weight gain but did 1101 affect final weight of dams, dams weight gain, litter size and birth weight of youngs. The best level of Single Cell Protein as substitutes Meat Bone Meal is 3% SCP or 50% substituted MBM. Jt is concluded that 50% MBM could be replaced with SCP in mice diet without affecting mice reproduction. Key words : Single Cell Protein, Meat and Bone Meal, Mice, Reproduction

Judul: Pengaruh Protein Hewani Ransum Yang Berbeda Terhadap Pertumbuhan dan Keefisienan  Makanan Mencit (Mus musculus albus)
Abstrak: Penelitian ini dilakukan di Laboratorium Pemuliaan dan Genetika Ternak, Jurusan Ilmu Produksi Ternak, Fakultas Peternakan Institut Pertanian Bogor. Penelitian dimulai tanggal 22 September 1988 sampai tanggal 14 November 1988. Penelitian ini menggunakan hewan laboratorium mencit (Mus musculus albus) sebanyak 288 ekor mencit Jantan dan 286 ekor mencit betina keturunan 180 ekor induk yang dika- winkan dengan 60 ekor pejantan. Mencit induk dan pejantan tersebut dibagi secara acak dalam qua kelompok pesar dan dikawinkan dengan perbandingan satu jantan untuk tiga ekor betina. Pembagian an didasarkan pada pemberian ransum, yakni ransum yang mengandung protein hewanı 9% atau protein hewani 3%. Penelitian ini bertujuan untuk mendapatkan keterangan mengenai pengaruh kadar protein hewani sembilan persen dan tiga persen terhadap bobot badan, laju pertumbuhan, keef1- sienan makanan, dan korelasi antara bobot sapih umur 21 ha- ri dengan bobot bada umur 28, 42 dan 56 hari. Hasil penelitian menunjukan protein hewani ransum ti- dak berpengaruh terhadap bobot sapih mencit betina dan mencit jantan. Pada umur 42 hari kadar protein hewani tinggi berpengaruh sangat nyata (p < 0.01) terhadap bobot badan mencit dibandingkan dengan protein hewani rendah. Pada umur 49 hari dan 56 harı kadar protein hewani sembilan persen berpengaruh sangat nyata (p < 0.01) ter- hadap bobot badan mencit betina, sedangkan terhadap bobot badan mencit jantan hanya berpengaruh nyata (p < 0.05). Kadar protein hewani ransum sembilan persen dan tiga persen berpengaruh sangat nyata (p < 0.01) terhadap laju pertumbuhan absolut mencit setelah berumur 28 hari, kecua- 11 pada periode umur 42 49 hari, protein hewani ransum yang berbeda tidak mempengaruhi laju pertumbuhan . absolut mencit. ...

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.
