Judul: Kalkulasi Biomassa Karbon pada Ekosistem Mangrove di Pesisir Kabupaten Tangerang
Abstrak: Kabupaten Tangerang memiliki potensi mangrove di wilayah pesisirnya yang berperan penting dalam penyerapan karbon yang disimpan dalam bentuk bimassa mangrove. Penelitan ini bertujuan menentukan kemampuan mangrove dalam menyimpan karbon serta rencana pengelolaannya di Pesisir Kabupaten Tangerang. Penelitian dilakukan di Desa Ketapang, Patramanggala dan Tanjung Pasir. Persamaan alometrik digunakan untuk meghitung biomassa mangrove kemudian stok karbon disetimasi. Hasil penelitian menunjukkan kerapatan mangrove tertinggi sebesar 274 ind/ha.. Rata- rata stok karbon dan serapan emisi karbon jenis Rhizhopora stylosa adalah 0,75ton C/ha (2,74 ton CO2e/ha), jenis Avicennia marina 13,41ton C/ha (49,17 ton CO2e/ha), jenis Avicennia alba 0,50ton C/ha (1,84 ton CO2e/ha) dan jenis Rhizophora mucronata mencapai 0,14ton C/ha (0,51 ton CO2e/ha). Rata-rata stok karbon Desa Ketapang 3,70ton C/ha, Desa Patramanggala mencapai 3,32ton C/ha dan Desa Tanjung Pasir mencapai 3,55ton C/ha Kemampuan mangrove dalam menyerap karbon tertinggi ditemukan pada jenis Avicennia marina dan desa simpanan karbon tertinggi adalah Desa Ketapang., Tangerang Regency has the potential of mangroves in its coastal areas and important role carbon sequestration and absorption in biomass. This study purpose to determine the ability of mangroves to absorb carbon and their management plans in Coastal Tangerang. The research Ketapang village, Patramangala and Tanjung Pasir. Allometric equations are used to calculate mangrove biomass and then carbon stock is estimated. The results showed the average carbon stock and carbon emission absorption of Rhizhopora stylosa is 0.75 tonsC/ha (2,74 tons CO2e/ha), Avicennia marina is 13.41tons C/ha (49,17 tons CO2e/ha) Avicennia alba is 0.50tons C/ha (1,84 tons CO2e/ha) and Rhizophora mucronata is 0.14 tons C/ha (0,51 tons CO2e/ha). The average stock carbon based on different locations, namely Ketapang Village reached 3.70tons C/ha, Patramangala Village reached 3.32tons C/ha and Tanjung Pasir Village reached 3.55tons C/ha The highest ability of mangroves to absorb carbon was found on the Avicennia marina species and the village with the highest carbon is Ketapang Village.

Judul: Estimation of Mangrove Carbon Sequestration Based  on Environmental Characteristics in the Coastal Area of Tanjung Village, Sumenep,  Madura
Abstrak: Ekosistem pesisir memiliki potensi serapan karbon yang besar dan mampu menyimpannya hingga ribuan tahun. Mangrove menyerap CO2 dan mengubahnya menjadi karbon organik (karbohidrat) melalui proses fotosintesis. Oleh karena itu, penelitian perlu dilakukan untuk mengetahui potensi simpanan dan serapan karbon ekositem mangrove di pesisir Desa Tanjung, Kabupaten Sumenep, Madura. Data serapan dan simpanan karbon diperoleh menggunakan metode alometrik dan Walkley and Black. Kawasan mangrove di Pesisir Desa Tanjung memiliki luasan 13,75 ha. Spesies mangrove yang mendominasi di pesisir Desa Tanjung yaitu spesies Sonneratia alba. Stasiun 4 memiliki simpanan dan serapan karbon mangrove tertinggi yaitu 18,65 ton C/ha dan 68,39 ton CO2eq/ha. Simpanan karbon sedimen tertinggi terdapat di Stasiun 4 (35,87 ton C/ha). Mangrove Desa Tanjung mampu menyimpan karbon sebesar 491,88 ton C dengan nilai serapan karbon pada tegakan mangrove yaitu 1543,33 ton CO2eq., Coastal ecosystems have the potential to absorb large amounts of carbon and are able to store it for thousands of years. These ecosystems include seagrass ecosystems, salt marsh ecosystems and mangrove ecosystems. Mangroves absorb CO2 and convert it into organic carbon (carbohydrates) through the process of photosynthesis. Therefore, research needs to be carried out to determine the potential for carbon storage and sequestration in the mangrove ecosystem on the coast of Tanjung Village, Sumenep Regency, Madura. Allometric and Walkley and Black methods obtained carbon sequestration and storage data. The mangrove area on the coast of Tanjung Village has an area of 13,75 ha. Mangrove species that dominates Tanjung Village’s coast is Sonneratia alba. Station 4 has the highest mangrove carbon storage and sequestration, which were 18,65 ton C/ha and 68,39 ton CO2eq/ha. The highest sediment carbon storage was at Station 4 (35,87 ton C/ha). Tanjung Village mangroves were capable of storing carbon of 491,88 ton C with a carbon sequestration value in mangrove stands of 1543,33 ton CO2eq.

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.
