Judul: Estimation of Biomass and CO2 Uptake of the Upper Stand of Community Forest Stands in Cimanggu Village, Cikembar District, Sukabumi Regency
Abstrak: Keberadaan hutan rakyat dapat dijadikan sebagai alternatif untuk meningkatkan serapan CO2 di atmosfer, melihat saat ini terjadi penurunan udara karena kurangnya sumber serapan alami. Tujuan penelitian ini adalah untuk mengetahui informasi mengenai besarnya dugaan biomassa, cadangan karbon, dan serapan CO2. Metode yang digunakan dalam pengambilan data pada setiap responden menggunakan sensus, sedangkan penentuan lokasi dan penentuan responden dipilih secara purposive sebanyak 36 responden berdasarkan luasannya di 4 dusun. Kandungan biomassa diduga menggunakan rumus persamaan allometrik dan metode konversi volume dengan menggunakan BEF. Hasil penelitian menunjukkan total dan rata-rata simpanan dugaan biomassa sebesar 179,22 ton dan 11,908 ton/ha. Total dan rata-rata stok karbon per satuan luas adalah 205,225 ton/ha dan 5,701 ton/ha, sedangkan dugaan serapan sebesar CO2 753,176 ton/ha dan 20,922 ton/ha. Dusun yang memiliki total dan rata-rata serapan CO2 terbesar adalah Dusun Cikembang sebanyak 333,723 ton/ha dan 37,08 ton/ha., The existence of community forests can be used as an alternative to increase CO2 absorption in the atmosphere, seeing that currently there is a decrease in air due to a lack of natural sources of absorption. The purpose of this study was to find out information about the magnitude of the estimated biomass, carbon stocks, and CO2 absorption. The method used in collecting data on each respondent was using a census, while determining the location and determining the respondents purposively selected as many as 36 respondents based on their area in 4 hamlets. Biomass content was estimated using the allometric equation formula and the volume conversion method using BEF. The results showed that the total and average estimated biomass savings were 179.22 tons and 11.908 tons/ha. The total and average carbon stocks per unit area are 205.225 tons/ha and 5.701 tons/ha, while the estimated CO2 absorption is 753.176 tons/ha and 20.922 tons/ha. The hamlets that have the largest total and average CO2 absorption are Cikembang Hamlet with 333.723 tons/ha and 37.08 tons/ha.

Judul: Analysis of Carbon Absorption Potential Development in The Community Forest of Karacak Village, Bogor Regency, West Java
Abstrak: Hutan rakyat merupakan salah satu alternatif yang perlu diketahui kemampuannya dalam menyerap dan menyimpan karbon karena dalam perencaannya melibatkan masyarakat yang menguasai pengetahuan alam di daerahnya. Penelitian ini bertujuan untuk mengetahui pola pengelolaan dan dugaan cadangan serta kemampuan serapan karbon yang dimiliki hutan rakyat di Desa Karacak. Pengambilan data dilakukan kepada 30 plot contoh yang dibagi berdasarkan kelas kemiringan lahan. Hasil inventarisasi menunjukkan hutan Desa Karacak termasuk dalam tipe hutan rakyat kebun campuran dengan 8 jenis pohon penghasil non-kayu dan 2 pohon jenis penghasil kayu. Hasil pengolahan data menunjukkan dugaan rata-rata kemampuan cadangan karbon terbagi dalam kemiringan landai 36,23 tonC/ha, kemiringan bergelombang 37,98 tonC/ha dan kemiringan berbukit 38,65 tonC/ha dengan total rata-rata 37,62 tonC/ha. Dugaan rata-rata kemampuan serap karbon dioksida terbagi dalam kemiringan landai 7,62 tonCO2/ha/tahun, kemiringan bergelombang 7,73 tonCO2/ha/tahun dan kemiringan berbukit 6,69 tonCO2/ha/tahun dengan total rata-rata 7,35 tonCO2/ha/tahun., Community forests are one of the alternatives that need to be recognized for their carbon sequestration and reserves capability, as their planning involves the local community which possesses indigenous knowledge of their natural environment. This research aims to determine the management pattern and estimate carbon sequestration, as well as reserves capabilities of community forest in Karacak Village. The data collection was implemented on 30 sample plots, categorized based on the slope class. The inventory results indicate that the forest in Karacak Village falls under the category of mixed garden community forests, comprising 8 types of non-timber-producing trees and 2 types of timber-producing trees. Data processing results reveal an estimated average carbon reserve capacity distributed as follows: for flat terrain, 36,23 tons C/ha; undulating terrain, 37,98 tons C/ha; and hilly terrain, 38,65 tons C/ha, with a total average of 37,62 tons C/ha. The estimated average carbon dioxide sequestration capacity is stratified as follows: for flat terrain, 7,62 tons CO2/ha/year; undulating terrain, 7,73 tons CO2/ha/year; and hilly terrain, 6,69 tons CO2/ha/year, with a total average of 7,35 tons CO2/ha/year.

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.
