Judul: Perubahan Makroskopis dan Mikroskopis Ginjal Anjing Akibat Nefrektomi Unilateral
Abstrak: Nefroktomi merupakan pembuangan atau pemotongan ginjal dari dalam tubuh yang dapat bersifat bilateral atau unilateral. Pada Nefroktomi unilateral akan mengakibtakan perubahan pada ginjal yang masih tertinggal di dalam tubuh berupa hipertropi kompensator sebagai adaptasi organ hewan tersebut terhadap lingkungannya.

Judul: Gambaran darah anjing sebelum dan sesudah nephectomi uniteral
Abstrak: University Tujuan penelitian untuk mengetahui ada tidaknya perubahan gambaran darah akibat nephrectomi (pengambilan ginjal). Ginjal mempunyai hubungan erat dengan darah karena fungsi ginjal sebagai organ endokrin yang menghasilkan erithropoitin. Erithropoitin adalah suatu hormon yang mengatur erithropoisis atau pembentukan sel darah merah. Pemeriksaan dilakukan pada 5 ekor anjing lokal dengan selang umur 0,5-2 tahun. Gambaran darah yang diperiksa terdiri atas jumlah erithrosit, leukosit, hematokrit, hemoglobin, MCV, MCH, dan MCHC. Metode yang digunakan untuk pemeriksaan dengan hemositometer, acid hematin tipe Sahli dan micro hematokrit. Pengujian secara statistik dimaksudkan untuk membandingkan nilai rata-rata sebelum operasi dengan nilai rata-rata sesudah operasi. Sebelum operasi dilakukan pemeriksaan 2 kali, kemudian dirata-rata. Hasil rata-rata ini dibandingkan dengan rata-rata hari ke 2, 4, 6, 8, 10, dan 12 setelah operasi. Masing-masing diuji secara statistik menggunakan. rancangan acak lengkap dengan membandingkan secara berpasangan. Jadi terdapat 6 pasang pengujian, masing-masing membandingkan rata-rata sebelum operasi dengan hari ke 2, 4, 6, 8, 10 dan 12 setelah operasi. Sebelumnyajuga dilakukan uji F untuk mengetahui kesamaan varians, yang ternyata mempunyai varian yang homogen. Hasil pengujian nilai rata-rata secara statistik dengan : 0,05. Perbedaan nyata yang menunjukkan penurunan setelah operasi terdapat pada pemeriksaan : a) hematokrit terjadi pada hari ke 6 setelah operasi sampai pemeriksaan terakhir, b) erithrosit penurunan yang nyata pada hari ke 8 setelah operasi, dan c) leukosit penurunan yang nyata terjadi pada hari ke 10 dan 12 setelah operasi. Perbedaan nyata menunjukkan kenaikan setelah operasi terdapat pada pemeriksaan : a) hemoglobin pada hari ke 6 setelah operasi, b) MCHC pada hari ke 6 dan 8 setelah operasi. Pada hari ke 12 setelah operasi nephrectomi penurunan hematokrit dan leukosit masih menunjukkan penurunan yang berbeda nyata. Dari hasil penelitian inį, disarankan sampai 12 hari setelah nephrectomi sebaiknya anjing masih diberi pe- rawatan khusus, dengan memberikan obat-obatan atau makanan yang merangsang pembentukan darah…

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.
