Judul: Pengaruh Ekstrak Teripang Oler (Holothuria atra) Terhadap Organ
Pencernaan Tikus Putih (Rattus norvegicus)
Abstrak: Teripang diketahui memiliki kandungan nutrisi yang tinggi dan kaya dengan bahan bioaktif yang menunjukkan manfaat medis. Saat ini teripang banyak dimanfaatkan dalam industri makanan dan biomedis, namun manfaatnya terhadap organ pencernaan masih belum diketahui secara ilmiah. Penelitian ini bertujuan untuk mengamati pengaruh pemberian ekstrak teripang oler (Holothuria atra) terhadap morfologi organ lambung, pankreas, dan usus halus pada saluran pencernaan tikus putih (Rattus norvegicus). Sebanyak 18 ekor tikus dibagi dalam enam kelompok dengan pemberian ekstrak teripang dengan dosis bertingkat. Kelompok B, C, D, E, dan F masing-masing diberi ekstrak teripang pada dosis 25 mg/kgBB, 50 mg/kgBB, 100 mg/kgBB, 200 mg/kgBB, dan 400 mg/kgBB, sedangkan kelompok A merupakan kelompok kontrol diberi aquadest. Pemberian ekstrak teripang dilakukan dengan menggunakan sonde lambung. Seluruh tikus dinekropsi setelah pemberian pelakuan selama 90 hari. Organ lambung, usus, dan pankreas dijadikan sampel dan diproses menjadi sediaan histopatologi menggunakan pewarnaan Hematoksilin-Eosin (HE). Pemberian ekstrak teripang pada kelompok C menunjukkan peningkatan jumlah sel parietal dan sel Chief di lambung, penurunan sel degenerasi di pankreas, dan peningkatan tinggi vili, luas permukaan vili, dan jumlah kripta serta penurunan jumlah sel radang submukosa di usus halus. Berdasarkan hasil penelitian ini, ekstrak teripang pada kelompok C memberi pengaruh yang paling baik. Penggunaan teripang dengan dosis 50 mg/kgBB berpotensi untuk dimanfaatkan.

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.
