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: Performans Organ Reproduksi Mencit (Mus musculus) yang Diberi Pakan Mengandung Protein Sel Tunggal
Abstrak: Reproduksi ternak ditentukan oleh kemampuannya untuk menghasilkan selsel kelamin yang berkualitas dan melakukan aktivitas reproduksi agar dapat menghasilkan individu baru dalam waktu yang singkat. Untuk menghasilkan sel-sel kelamin yang baik dibutuhkan dukungan organ-organ kelamin yang dapat berfungsi dengan normal. Sel-sel dalam organ reproduksi tersebut membutuhkan masukan nutrisi yang berkualitas. Dengan demikian kualitas pakan turut juga mempengaruhi performa organ-organ reproduksi. Sumber protein alternatif yang dapat digunakan adalah Protein Sel Tunggal (PST) . Penggunaan PST selain menguntungkan secara ekonomis dan nutrisi, ternyata banyak penelitian menunjukkan pengaruh terhadap organ-organ vital. Pengaruh yang sama mungkin dapat terjadi pada organ-organ reproduksi. Penelitian ini bertujuan untuk mengetahui pengaruh penggunaan PST sebagai substitusi Meat and Bone Meal (MBM) pada ransum terhadap performan organorgan reproduksi. Taraf substitusi yang diujikan yaitu 0%, 1,5%, 3%, 4,5% dan 6% terhadap MBM. Hewan percobaan yang digunakan adalah mencit sejumlah 50 ekor (jantan dan betina) yang akan dibagi dalam lima perlakuan dan lima ulangan dengan diberi pakan dan minum ad libitum. Masing-masing ulangan terdiri atas dua ekor. Mencit dipelihara selama dua bulan dan pengamatan dilakukan di akhir penelitian. Peubah yang diukur meliputi bobot, panjang dan diameter testis, panjang vas deferens, jumlah sperma mencit jantan serta bobot dan panjang organ reproduksi betina. Selain itu dilakukan uji histopatologi terhadap organ reproduksi jantan maupun 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.
