Judul: Estimasi Serapan Karbon Mangrove di Desa Pasar Banggi, Rembang, Jawa Tengah
Abstrak: Desa Pasar Banggi merupakan salah satu desa yang berada di Kabupaten Rembang yang memiliki potensi mangrove di wilayah pesisirnya yang memiliki peran penting dalam penyerapan karbon. Penelitian ini bertujuan menentukan kemampuan mangrove dalam menyerap besarnya karbon. Penelitian ini dilakukan di Desa Pasar Banggi, Rembang, Jawa tengah pada bulan Februari 2021. Biomassa karbon dihitung menggunakan persamaan alometrik dan dikalikan dengan stok C agar diperoleh serapan karbon mangrove. Hasil penelitian menunjukkan bahwa kerapatan mangrove tertinggi sebesar 9767 ind/Ha. Jumlah tegakan pada lokasi penelitian berbeda di setiap stasiun. Biomassa memiliki hubungan positif dengan serapan karbon mangrove. Nilai biomassa tertinggi yaitu 514,33 ton/ha dan terendah sebesar 150,25 ton/ha. Besar kecilnya serapan karbon pada sedimen dipengaruhi oleh substrat mangrove. Substrat berlumpur memiliki kemampuan lebih tinggi dalam menyimpan karbon karena memiliki pori-pori yang lebih kecil jika dibandingkan substrat berpasir. Mangrove di Desa Pasar Banggi memiliki serapan karbon sebesar 882,96 ton/ha dan simpanan karbon sedimen sebesar 11039,30 ton/ha.

Judul: Cadangan Karbon Tegakan Mangrove di Desa Pasar Banggi Kabupaten Rembang, Jawa Tengah
Abstrak: Mangroves are usually used as a prevention of coastal erosion and the fish farming (ponds). Ecologically mangrove has potential as carbon stocks. Mangroves that located in Pasar Banggi Village Rembang Regencyhave a function as conservation area. There are four types of mangroves such as Rhizophora mucronata, Rhizophora apiculata, Sonneratia alba, and Avicennia marina. The purposes of this study are to calculate the biomass,the carbon stocks and CO2 sequestration estimation using per tree method and midpoint diameter calculation method. The result showed that the value of the biomass, carbon stocks, and CO2 sequestration consecutively are 81.274 ton/ha, 38.199 ton/ha, dan 140.190 ton/ha. The use of midpoint diameter calculation method can not be applied to find out the value of the biomass, carbon stocks, and CO2 sequestration in mangrove of Pasar Banggi Village Rembang Regency because it has a significant difference.

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.
