Judul: Species Composition, Stand Structure, Estimation of Biomass and Carbon Content in PIK Mangrove Ecotourism Area, DKI Jakarta
Abstrak: Hutan mangrove memiliki daya simpan karbon yang tinggi, sehingga berpotensi dalam upaya mitigasi perubahan iklim. Penelitian ini bertujuan untuk menganalisis komposisi jenis, struktur tegakan, kandungan biomassa, simpanan karbon, dan serapan karbon dioksida tegakan mangrove di Kawasan Ekowisata Mangrove Pantai Indah Kapuk (PIK), DKI Jakarta. Metode penelitian ini, yaitu stratified random sampling dan perhitungan jumlah plot pengamatan menggunakan rumus Slovin. Analisis simpanan karbon dilakukan menggunakan persamaan alometrik. Dari hasil analisis vegetasi terdapat 10 jenis mangrove, yaitu Rhizophora mucronata, Avicennia marina, Sonneratia caseolaris, Excoecaria agallocha, Cerbera manghas, Terminalia catappa, Rhizophora apiculata, Calophyllum inophyllum, Morinda citrifolia, dan Nypa fruticans. Total biomassa, simpanan karbon, dan serapan karbon dioksida oleh tegakan mangrove secara berturut-turut sebesar 253,18 ton ha-1, 119 ton ha-1, dan 436,71 ton ha-1. Besarnya nilai simpanan karbon dan serapan karbon dioksida dipengaruhi oleh faktor lingkungan yang ada di kawasan pertumbuhan tegakan mangrove.

Judul: Studi Kasus Liver Neoplasia pada Anjing Shih Tzu
Abstrak: Liver neoplasia is the excessive and uncontrolled replication of hepatocytes that forms nodules visible in ultrasonography. The purpose of this study is to study and discuss the characteristic, diagnosis and treatment of liver neoplasm through the interpretation of ultrasonography and hematology in a Shih Tzu dog. Ultrasonography is conducted with a Chison Q8 ultrasound machine with a 5 to 7 MHz frequency convex probe on lateral recumbency. The blood cells, liver enzymes and nodules sizes were the main parameters in this study. The results in the period of three years from 2021 to 2023 were interpreted and supported with secondary data sources. The Shih Tzu dog is 14 years old in the year 2023 with a body weight of 5.21kg. No obvious clinical signs were observed during previous examinations. However, lethargy, vomiting and anorexia were recorded in its latest examination. Thrombocytosis, granulocytosis, high liver enzymes and hypoglycemia, which are some of the neoplastic clinical manifestations were also presented by this patient. Besides, liver neoplasm, spleen neoplasm and biliary sludge were the sonogram findings of this patient. The liver and spleen neoplasm was observed stable, while the biliary sludge volume fluctuated. The treatment strategy recorded is Ondansetron, Samylin®, Ornipural and Ursodeoxycholic acid.
