Judul: Pengaruh induksi lachesis terhadap peningkatan respon fagositosis sel fagosit peritoneum mencit yang diinfeksi streptococcus agalactiae
Abstrak: Homeopathy merupakan pengobatan alternatif yang efektif bagi penyakit infeksius yang disebabkan oleh bakteri maupun virus. Prinsip kerja homeopathy adalah pengobatan dilakukan berdasarkan gejala yang ditampilkan individu yang sehat. Lachesis merupakan homeopathy yang digunakan pada berbagai ruminansia, berperan sebagai imunomodulator, pemberian homeopathy dalam dosis kecil akan bekerja sebagai imunostimulan. Penelitian ini bertujuan untuk mengetahui pengaruh induksi lachesis terhadap peningkatan respon fagositosis sel fagosit peritoneum mencit yang diinfeksi dengan bakteri S. agalactiae. Penelitian dilakukan dengan menginduksi mencit dengan lachesis sebanyak 0,1 ml dengan masa induksi 24 jam, 48 jam dan 72 jam. Mencit yang telah diindusi lachesis diinfeksi dengan bakteri S. agalactiae kemudian diamati respon fagositosis dengan membuat sediaan ulas cairan peritoneum mencit dengan teknik pewarnaan Giemsa. Respon fagositosis yang diukur adalah aktivitas dan kapasitas fagositosis. Hasil penelitian menunjukan bahwa pada ketiga kelompok masa induksi lachesis, terjadi peningkatan respon fagositosis yang berbeda nyata (P<0,05). Kelompok mencit dengan masa induksi 72 jam memiliki aktivitas dan kapasitas fagositosis tertinggi.

Abstrak: Kajian Histopatologis terhadap jaringan ambing mencit bunting yang diimunisasi S. agalactiae hemaglutinin positif dilakukan pada 6 ekor mencit balb-C yang dibagi l11enjadi 3 kelompok yaitu kelompok kontral negatif, kontral positif dan kelompok yang diimunisasi. Mencit-l11encit tersebut diimunisasi dengan suspensi bakteri utuh s.agalacliae hemaglutinin positif sebanyak 0,1 mllekor mencit melalui rute intraperitoneal. Empat hari setelah dilakukan uji tantang dengan bakteri yang sama, ambing mencit dikoleksi dan diperiksa secm'a histopatologis. Hasil pengamatan menunjukkan bahwa imunisasi tidak memberikan perlindungan terhadap uji tantang yang dilakukan.

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.
