Judul: Estimation of Above Ground Biomass of Mangrove Vegetation in Indramayu Regency, West Java
Abstrak: Mangrove memiliki fungsi ekologis dan ekonomis yang penting di wilayah pesisir. Kabupaten Indramayu merupakan salah satu wilayah yang berada di pesisir pantai utara Pulau Jawa dan memiliki vegetasi mangrove. Mangrove memiliki peranan penting dalam menyerap karbon di atmosfer melalui proses fotosintesis dan disimpan dalam bentuk biomassa, sehingga dapat menjadi salah satu cara efektif mitigasi perubahan iklim. Penelitian ini bertujuan untuk mengetahui nilai estimasi biomassa atas permukaan vegetasi mangrove di Kabupaten Indramayu. Metode yang digunakan adalah non-destructive atau tidak merusak, yaitu dengan cara mengukur diameter setinggi dada (DBH) dan tinggi pohon yang kemudian dihitung menggunakan persamaan alometrik. Berdasarkan hasil analisis regresi dan uji koefisien regresi, didapat model terpilih yaitu AGB = 0,3757e11,356NDVI dengan nilai R2 sebesar 0,5272 atau 52,72% dan kemudian dibuat peta sebarannya. Peta sebaran biomassa atas permukaan yang dihasilkan dapat dijadikan acuan rencana pengelolaan dan pemanfaatan kawasan vegetasi mangrove di Kabupaten Indramayu. Kata kunci: biomassa atas permukaan, mangrove, mitigasi perubahan iklim., Mangroves plays important role in ecology and economy in coastal areas. Indramayu Regency is one of the areas located on the northern coast of Java Island and has mangrove vegetation. Mangroves have an important role in absorbing carbon in the atmosphere through the process of photosynthesis and stored in the form of biomass, so that it can be an effective way of mitigating climate change. This study aims to determine the estimated biomass on the surface of mangrove vegetation in Indramayu Regency. The method used is non-destructive or non-destructive, namely by measuring the diameter at breast height (DBH) and tree height which is then calculated using allometric equations. Based on the regression analysis and regression coefficient test, the selected model is AGB = 0,3757e11,356NDVI with an R2 value of 0.5272 or 52,72% and then a distribution map is made. The resulting surface distribution map of biomass can be used as a reference for the management plan and utilization of mangrove vegetation areas in Indramayu Regency.

Judul: Estimation of Carbon Content in Mangrove Stands in the Karangsong Mangrove Ecotourism Area, Indramayu Regency
Abstrak: Hutan mangrove mempunyai potensi mitigasi perubahan iklim karena kemampuannya dalam menyerap dan menyimpan karbon dalam waktu lama dan dalam jumlah besar. Adanya alih fungsi lahan dapat merubah komposisi vegetasi hutan mangrove dan mengurangi simpanan karbon. Penelitian ini bertujuan untuk mengetahui komposisi vegetasi pada kawasan ekowisata mangrove Karangsong dan mengetahui kemampuan mangrove dalam menyerap serta menyimpan karbon. Metode dalam penelitian ini yaitu jalur garis berpetak pada 10 titik stasiun pengamatan yang dianggap mewakili keseluruhan karakteristik vegetasi dengan total intensitas sampling sebesar 5%. Analisis kandungan karbon dilakukan menggunakan persamaan alometrik. Dari hasil analisis vegetasi terdapat 4 jenis mangrove, yiatu Avicennia marina, Avicennia alba, Rhizophora stylosa, Rhizophora mucronata. Total biomassa, kandungan karbon dan simpanan karbon dioksida seluruh kawasan seluas 20 ha yaitu beturut-turut sebesar 99,14 ton/ha; 46,6 tonC/ha; 171 tonCO2 /ha. Besarnya kandungan karbon yang tersimpan di kawasan ekowisata Mangrove Karangsong dipengaruhi oleh faktor lingkungan yang terbentuk pada tegakan mangrove., Mangrove forests have the potential to mitigate climate change because of their ability to absorb and store carbon for a long time and in large quantities. The existence of land use change can change the composition of mangrove forest vegetation and reduce carbon sequestration. This study aims to determine the composition of vegetation in the Karangsong mangrove ecotourism area and to determine the ability of mangroves to absorb and store carbon. The method in this study was a line transect plot at 10 points of observation stations which are considered to represent the overall characteristics of the vegetation, the total sampling intensity is 5%. Carbon content analysis was carried out using allometric equations. From the results of the vegetation analysis, there were 4 types of mangroves, namely Avicennia marina, Avicennia alba, Rhizophora stylosa, and Rhizophora mucronata. The total biomass, carbon content, and carbon dioxide uptake in the entire area of 20 ha are 99.14 tons/ha; 46.6 tonsC/ha; and 171 tonsCO2/ha, respectively. The amount of carbon stored in the Karangsong Mangrove ecotourism area was influenced by environmental factors formed in the mangrove stands.

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.
