Judul: Pendugaan Biomassa, Karbon dan Serapan Karbon Dioksida Empat Jenis Tegakan di Hutan Pendidikan Gunung Walat
Abstrak: Hutan memiliki peranan penting dalam pengendalian pemanasan global dengan menyerap karbon dioksida (CO2) di atmosfer dan menyimpan karbon dalam bentuk biomassa hutan. Penelitian ini bertujuan menduga biomassa, simpanan karbon dan serapan karbon dioksida (CO2) pada empat jenis tegakan yakni agathis, puspa, meranti, dan kayu afrika di Hutan Pendidikan Gunung Walat. Pengukuran di lapangan berupa diameter pada semai, pancang, tiang, dan pohon. Plot contoh berbentuk persegi dengan ukuran 20 m × 20 m yang memiliki subplot-subplot untuk pengukuran semai, pancang, tiang, dan pohon. Analisis data pendugaan biomassa menggunakan persamaan alometrik biomassa. Kandungan karbon dan serapan karbon dioksida diperoleh dari konversi nilai biomassa. Hasil penelitian menunjukkan total biomassa agathis 14.646,77 ton/ha, biomassa puspa 6.436,02 ton/ha, biomassa meranti 91,31 ton/ha, dan biomassa kayu afrika 66,28 ton/ha. Karbon yang tersimpan pada agathis 6.883,98 ton/ha, puspa 3.024,93 ton/ha, meranti 42,92 ton/ha, dan kayu afrika 31,15 ton/ha. Serapan karbon dioksida agathis sebesar 25.241,26 ton/ha, puspa 11.091,41 ton/ha, meranti 157,36 ton/ha, dan kayu afrika 114,23 ton/ha., Forests have an important role in controlling global warming by absorbing carbon dioxide in the atmosphere and storing carbon in the form of forest biomass. This study aims to estimate biomass, carbon storage, and carbon dioxide uptake (CO2) in four types of stands namely agathis, puspa, meranti, and African wood in Gunung Walat Educational Forest. Measurements in the field in the form of diameters at various growth rates. The sample plot is a square with a size of 20 m × 20 m which has subplots for measuring seedlings, saplings, poles, and trees. Analysis of the biomass estimation data using the biomass allometric equation. Carbon content and carbon dioxide uptake were obtained from the conversion of biomass values. The results showed that the total biomass of agathis was 14.646,77 tons/ha, puspa biomass 6.436,02 tons/ha, meranti biomass 91,31 tons/ha, and african wood biomass 66,28 tons/ha. Carbon stored in agathis 6.883,98 tons/ha, puspa 3.024,93 tons/ha, meranti 42,917 tons/ha, and african wood 31,153 tons/ha. Carbon dioxide absorption of agathis was 25.241,26 tons/ha, puspa 11.091,41 tons/ha, meranti 157,36 tons/ha and african wood 114,23 tons/ha.

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.
