Biomass Carbon Stock in Sungsang IV Village, South Sumatra
Abstrak: Hutan mangrove sekunder memiliki nilai jasa ekosistem yang dapat menanggulangi perubahan iklim, walaupun tidak sebaik hutan mangrove primer. Hutan Desa Sungsang IV digunakan sebagai objek untuk melihat dan menganalisis bagaimana kerapatan dan keragaman vegetasi mangrove, serta estimasi potensi stok karbon biomassa di hutan mangrove sekunder. Analisis vegetasi dan kondisi lingkungan dilakukan pada 38 plot untuk menghitung nilai kerapatan dan keragaman spesies hutan mangrove sekunder, serta individu tingkat pohon untuk mengestimasi potensi stok karbon biomassa dengan persamaan alometrik. Rerata kerapatan vegetasi mangrove Hutan Desa Sungsang IV pada tingkat pohon 86 individu ha-1, tingkat pancang 583 individu ha-1, dan tingkat semai 9809 individu ha-1. Terdapat 12 spesies mangrove yang teridentifikasi, yakni Sonneratia caseolaris, Rhizophora apiculata, Avicennia alba, Nypa fruticans, Kandelia candel, Brugueira parviflora, Avicennia marina, Xylocarpus granatum, Aegiceras corniculatum, Acrostichum aureum, Acanthus ilicifolius, dan Bruguiera gymnorrhiza. Rerata estimasi potensi stok karbon biomassa vegetasi mangrove (tingkat pohon) Hutan Desa Sungsang IV sebesar 98 ton C ha-1., Secondary mangrove forests have ecosystem service value that can mitigate climate change, although they are not as good as primary mangrove forests. Sungsang IV Village Forest is used as an object to see and analyze the density and diversity of mangrove communities, as well as the estimation of potential biomass carbon stocks in secondary mangrove forests. Vegetation and environmental condition analyses were carried out on 38 plots to calculate the density and diversity values of mangrove secondary forest, as well as individual tree levels, to estimate potential biomass carbon stocks using allometric equations. The average density of mangrove vegetation in Sungsang IV Village Forest at the tree level was 86 individuals ha-1, the sapling level was 583 individuals ha-1, and the seedling level was 9809 individuals ha-1. There are 12 identified mangrove species, namely Sonneratia caseolaris, Rhizophora apiculata, Avicennia alba, Nypa fruticans, Kandelia candel, Brugueira parviflora, Avicennia marina, Xylocarpus granatum, Aegiceras corniculatum, Acrostichum aureum, Acanthus ilicifolius, and Bruguiera gymnorrhiza. The average estimated potential carbon stock of mangrove vegetation biomass (tree level) of Sungsang IV Village Forest is 98 tons C ha-1.

Judul: Estimation of Mangrove Carbon Stock Biomass Using  a Combination of Allometric and Spatial Methods in Mangrovesari Ecotourism, Brebes, Central Java
Abstrak: SAKILA AZRIL LIA. Estimasi Stok Karbon Biomassa Mangrove Menggunakan Kombinasi Metode Alometrik dan Spasial di Ekowisata Mangrovesari, Brebes, Jawa Tengah. Dibimbing oleh FERY KURNIAWAN dan ARIO DAMAR. Mangrove berpotensi untuk menyerap dan menyimpan karbon lima kali lebih efektif dari rata-rata simpanan karbon hutan tropis. Upaya rehabilitasi yang dilakukan oleh pengelola Mangrovesari berdampak positif dalam menambah luasan hutan mangrove secara signifikan. Penelitian ini bertujuan untuk mengestimasi stok karbon total ekosistem mangrove menggunakan pendekatan integrasi alometrik dan spasial di ekowisata Mangrovesari, Desa Kaliwlingi, Brebes, Jawa Tengah. Hasil penelitian menunjukkan bahwa spesies mangrove yang mendominasi di ekowisata Mangrovesari adalah Rhizophora mucronata. Faktor lingkungan seperti suhu, pH, salinitas, dan DO serta tipe substrat berpengaruh terhadap kerapatan mangrove. Kerapatan mangrove memiliki pengaruh positif terhadap biomassa dan stok karbon mangrove. Nilai stok karbon mangrove di ekowisata Mangrovesari dikelompokan ke dalam 3 kategori kerapatan mangrove. Mangrove dengan kategori jarang mengandung stok karbon sebesar 42,02 ton/ha, kategori sedang sebesar 26,61 ton/ha, kategori rapat sebesar 444,60 ton/ha, dan stok karbon mangrove total sebesar 513,2334 ton/ha.

Estimation of Stock Carbon Mangrove Biomass Using a Combination of Allometric and Spatial Methods in Mangrovesari Ecotourism, Brebes, Central Java Supervised by FERY KURNIAWAN and ARIO DAMAR. Mangroves have the potential to absorb and store carbon five times more effectively than the average tropical forest carbon storage. Rehabilitation efforts carried out by Mangrovesari managers have a positive impact in significantly increasing the area of mangrove forests. This study aims to estimate the total carbon stock of mangrove ecosystems using allometric and spatial integration approaches in Mangrovesari ecotourism, Kaliwlingi Village, Brebes, Central Java. The results showed that the dominating mangrove species in Mangrovesari ecotourism was Rhizophora mucronata. Environmental factors such as temperature, pH, salinity, and DO as well as substrate type affect mangrove density. Mangrove density has a positive influence on mangrove biomass and carbon stock. Mangrove carbon stock values in Mangrovesari ecotourism are grouped into 3 categories of mangrove density. Mangroves with sparse categories contain carbon stock of 42,02 tons/ha, medium category of 26,61 tons/ha, dense category of 444,60 tons/ha, and total mangrove carbon stock of 513,23 tons/ha.

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.
