Judul: Pendugaan Biomassa dan Serapan CO₂ Bagian Atas Tegakan Hutan Rakyat di Desa Gunung Bunder 2 Kecamatan Pamijahan Kabupaten Bogor
Abstrak: Hutan rakyat merupakan hutan yang dimiliki oleh masyarakat yang dinyatakan oleh kepemilikan lahan yang memiliki luas minimum sesuai Permenhut 88/2003 sebesar 0.25 ha serta penutupan tajuk dan tanaman lainnya lebih dari 50%. Kelestarian hutan rakyat ditentukan oleh struktur tegakan hutan. Penelitian ini bertujuan untuk mengetahui besarnya biomassa, cadangan karbon dan serapan CO2 per pemilik lahan hutan rakyat di desa Gunung Bunder 2 serta mengetahui perbedaan hasil pendugaan perhitungan biomassa dengan metode allometrik dan metode konversi volume menggunakan BEF. Pendugaan potensi biomassa menggunakan metode allometrik dan metode dengan BEF menghasilkan nilai dugaan berbeda nyata. Hasil rata-rata nilai dugaan biomassa dengan menggunakan metode allometrik dan metode BEF secara berturut-turut adalah 6.76 ton/ha dan 8.28 ton/ha. Dugaan cadangan karbon dan serapan CO2 dengan metode allometrik menghasilkan rata-rata nilai sebesar 3.18 ton/ha dan 11.67 ton/ha, sedangkan metode dengan menggunakan BEF sebesar 3.89 ton/ha dan 14.28 ton/ha., People's forest is a forest owned by the community declared by land ownership that has a minimum area according to Permenhut 88/2003 of 0.25 ha and the closure of timbers and other plants more than 50%. The preservation of people's forests is soothed by the structure of the forest stand. This study aims to find out the amount of biomass, carbon reserves and CO2 uptake per owner of people's forest land in the village of Gunung Bunder 2 and find out the difference in the results of the utilization of biomass calculations with allometric methods by using BEF. The restoration of biomass potential using allometric methods and methods with BEF produces real different conjecture values. The average yield of the alleged value of biomass using allometric methods and methods with BEF is 6.71 tons /ha and 8.28 tons/ha, of allf. Alleged carbon reserves and CO2 uptake by allometric methods produce an average value of 3.18 tons / ha and 11.67 tons / ha, while the method using BEF of 3.89 tons / ha and 14.28 tons / ha.

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: 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.
