Judul: Management Practice and Potential Carbon Sequestration in Karangrejo Village, Ngawi Regency
Abstrak: Hutan memiliki peran sekuestrasi dalam mitigasi perubahan iklim, karena hutan dapat menyerap emisi gas rumah kaca dalam bentuk biomassa tegakan. Tujuan dari penelitian ini mempraktikkan pengelolaan untuk meningkatkan sekuestrasi karbon dan menduga besarnya sekuestrasi karbon di Desa Karangrejo, Kabupaten Ngawi. Jawa Timur. Metode yang digunakan dalam pengambilan data pengelolaan menggunakan sensus, sedangkan dalam penentuan lokasi penelitian menggunakan teknik purposive sampling sebanyak 30 plot berdasarkan bentang lahan dan praktik pengelolaan selama 5 tahun terakhir. Kemampuan sekuestrasi dan cadangan karbon dipengaruhi oleh kerapatan tegakan, formasi jenis tanaman dan kesesuaian tempat tumbuh. Kemampuan sekuestrasi karbon di Desa Karangrejo, Kabupaten Ngawi memiliki rata - rata serapan sebesar 13,46 tonCO₂/ha/tahun dengan kemampuan sekuestrasi karbon pada kelas lereng datar, bergelombang, berbukit berturut - turut sebesar 11,09 tonCO₂/ha/tahun, 14,15 tonCO₂/ha/tahun dan 16,45 tonCO₂/ha/tahun., The forest plays a crucial role in climate change mitigation by sequestering greenhouse gas emissions through biomass absorption. The objective of this research is to implement management practices to enhance carbon sequestration and estimate the magnitude of carbon storage in Karangrejo Village, Ngawi Regency, East Java. The method used for data collection in management practices involved a census, while the determination of research locations utilized purposive sampling techniques on 30 plots based on land topography and management practices over the previous 5 years. The ability of carbon sequestration and reserves was influenced by stand density, plant species formation, and site suitability. The carbon sequestration capability in Karangrejo Village, Ngawi Regency, averaged 13.46 tons of CO₂/ha/year, with carbon sequestration capabilities on flat, undulating, and hilly slopes was 11.09 tons of CO₂/ha/year, 14.15 tons of CO₂/ha/year, and 16.45 tons of CO₂/ha/year, respectively.

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.
