Judul: Estimation of Biomass, Carbon and CO2Emissions in Litter and Humus in Gunung Walat Educational Forest, Sukabumi Regency
Abstrak: Hutan Pendidikan Gunung Walat (HPGW) sebagai hutan tanaman memiliki kontribusi serasah dan humus yang cukup tinggi terhadap potensi biomassa, karbon dan emisi CO2. Hal itu dikarenakan serasah dan humus di HPGW sangat melimpah. Penelitian ini bertujuan untuk menduga potensi biomassa, karbon dan menduga emisi CO2 di HPGW. Pengambilan data di lapangan dilakukan secara destruktif dengan metode simple random sampling yaitu peletakan plot contoh secara acak agar menggambarkan dan mewakili tiap tegakan yang ada di HPGW. Plot contoh berbentuk persegi dengan ukuran (2 x 2) m dengan total plot sebanyak 83 plot dengan total sampel yang diambil sebanyak 166 sampel. Pengambilan data di laboratorium dengan mengoven serasah dan humus pada suhu 105 °C selama 24 jam. Hasil dugaan biomassa serasah dan humus secara berturut-turut sebesar 3,91 ton/ha dan 0,923 ton/ha. Pendugaan karbon serasah dan humus secara berturut-turut sebesar 1,839 ton/ha dan 0,434 ton/ha. Emisi CO2 dari proses dekomposisi serasah dan humus secara berturut-turut diperkirakan sebesar 6,74 ton CO2/ha dan 1,59 ton CO2/ha., Gunung Walat Educational Forest (HPGW) as a plantation forest has a high litter and humus contribution to the potential for biomass, carbon and CO2 emissions. because the litter and humus in HPGW is very abundant. The purpose of this research is to estimate the potential of biomass, carbon and to estimate CO2 emissions in HPGW. Data collection in the field was carried out destructively with the simple random sampling method, namely the placement of sample plots at random in order to describe and represent each stand in the HPGW. The sample plots are square with the size (2 x 2) m with a total plot of 83 plots with a total of 166 samples taken. Data were collected in the laboratory by roasting the litter and humus at a temperature of 105 °C for 24 hours. The estimated results of litter and humus biomass were 3.91 tons/ha and 0.923 tons/ha, respectively. Estimation of litter and humus carbon was 1.839 tons/ha and 0.434 tons/ha, respectively. CO2 emissions from the decomposition of litter and humus were estimated at 6.74 tons CO2/ha and 1.59 tons CO2/ha, respectively.

Judul: Estimation of Potential Biomass, Carbon, and CO2 Absorption in Six Types of Stands in Gunung Walat Educational Forest, Sukabumi
Abstrak: Forest is an area that is mainly overgrown with trees and other woody plants that occupy a fairly large area. Forests play an important role as carbon stores and absorbers of carbon dioxide (CO2) where the biomass of trees and forest vegetation contains very large carbon stocks. This study aims to estimate the potential for biomass, carbon stocks, and to determine the potential for CO2 uptake in six stands in the Gunung Walat Educational Forest (HPGW), Sukabumi, West Java. Field data were collected on stands of Acacia (Acacia sp.), Gamal (Gliricidia sp.), Mahogany (Swietenia macrophylla), Pinus (Pinus sp.), Sengon (Albizia chinensis), Sonokeling (Dalbergia latifolia). The sample plots are 83 square plots with a plot size of (20 x 20) m for trees with subplots (10 x 10) m for poles, (5 x 5) m for saplings, and (2 x 2) m for seedlings. Estimation of biomass value using allometric equations. The results of the study showed the total biomass value of acacia 15,03 tons ha-¹, gamal 1.057,76 tons ha-¹, mahogany 586,50 tons ha-¹, pine 15782,31 tons ha-¹, sengon 0,03 tons ha-¹, sonokeling 8,14 tons ha-¹. Total carbon stock of acacia 7,06 tons ha-¹, gamal 519,58 tons ha-¹, mahogany 275,66 tons ha-¹, pinus 7.417,69 tons ha-¹, sengon 0,00 tons ha-¹, sonokeling 3,82 tons ha-¹. Total CO2 absorption acacia 25,92 tons ha-¹, gamal 1824,53 tons ha-¹, mahogany 1.011,66 tons ha-¹, pine 27.222,91 tons ha-¹, sengon 0,02 tons ha-¹, sonokeling 14,04 tons ha-¹.

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.
