Judul: Management of Mangrove Ecosystems in the Musi River Estuary as an Effort to Decrease Carbon Emissions
Abstrak: Jasa ekosistem mangrove selain berfungsi secara ekologis bagi sektor perikanan, juga memiliki jasa ekosistem yang berfungsi dalam mitigasi perubahan iklim sebagai penyerap dan penyimpan karbon. Muara Sungai Musi di Kabupaten Banyuasin, Sumatera Selatan merupakan salah satu wilayah yang memiliki ekosistem mangrove yang luas, sehingga berpotensi dapat dijadikan salah satu solusi dalam menyerap emisi karbon. Beberapa penelitian menyatakan telah terjadi penurunan kualitas lingkungan hutan mangrove dan perubahan penggunaan lahan sebagai akibat dari reklamasi Tanjung Api-api (Kabupaten Banyuasin). Hutan mangrove di pesisir Banyuasin telah mengalami perubahan menjadi lahan terbuka, sawah, rawa, tambak, semak belukar. Data Pemprov Sumsel juga menyatakan bahwa Kabupaten Banyuasin berada pada urutan kedua dalam penghasil emisi karbon terbesar pada sektor berbasis lahan di Provinsi Sumatera Selatan. Penelitian ini bertujuan untuk menganalisis potensi cadangan karbon pada vegetasi mangrove di muara Sungai Musi, Sumatera Selatan dalam upaya penurunan emisi karbon. Tujuan ini didukung oleh beberapa tujuan khusus, yaitu (1) menganalisis struktur komunitas vegetasi mangrove di muara Sungai Musi; (2) menganalisis potensi cadangan karbon vegetasi mangrove di muara Sungai Musi; (3) menganalisis nilai ekonomi cadangan karbon mangrove di Muara Sungai Musi; dan (4) menganalisis peranan pemerintah dan persepsi masyarakat dalam pengelolaan mangrove sebagai mitigasi emisi karbon. Pengambilan data mangrove dilakukan di lima stasiun dengan menggunakan metode transek kuadrat seluas 100 m yang diletakkan secara vertikal terhadap garis pantai. Data persepsi dan identifikasi stakeholder didapatkan melalui wawancara. Pengolahan data mencakup persamaan allometrik untuk mengetahui biomassa, perhitungan simpanan karbon serta nilai ekonomi. Ekosistem mangrove di Muara Sungai Musi adalah Sonneratia alba, Nypa fruticans, Sonneratia casiolaris, dan Rhizophora apiculata. Jenis mangrove yang memiliki peranan penting dalam keberlangsungan ekosistem adalah jenis Nypa fruticans dan Sonneratia alba, dengan masing-masing INP adalah 145,6 dan 101,28. Cadangan karbon mangrove di muara Sungai Musi adalah sebesar 107,34 tonC/ha dan serapan karbon dioksida sebesar 393,59 tCO2 /ha dengan luasan mangrove sebesar ± 5276 ha. Nilai total estimasi ekonomi simpanan karbon yang dihasilkan adalah sebesar Rp174.441.016.895,00 (pasar sukarela) dan Rp455.872.524.151,00 (CDM). Rekomendasi pengelolaan untuk peningkatan cadangan karbon diantaranya adalah: pemberdayaan dan peningkatan pengetahuan masyarakat sekitar, rehabilitasi hutan dan lahan, pengembangan hasil hutan non kayu, pengembangan teknik budidaya agroforestry dan konservasi tanah dan air. Pengelolaan untuk pencegahan penurunan cadangan karbon dapat berupa perlindungan dan konservasi sumber daya alam serta pencegahan dan pengendalian kebakaran hutan dan lahan., Apart from having an ecological function for the fishery sector, mangrove also have ecosystem services that function in mitigating climate change as a carbon sink and storage. Musi River Estuary is located at Banyuasin Regency is one of the regency that has an extensive mangrove ecosystem in South Sumatra. Mangrove in this area has potential to be used as a solution in absorbing carbon emissions. Several studies have stated that there has been a decrease in the environmental quality of mangrove forests and changes in land use as a result of the reclamation of the Tanjung Api-api, Banyuasin Regency. The mangrove forests on the Banyuasin coast have been transformed into open land, rice fields, swamps, ponds, and shrubs. Data from the South Sumatra Provincial Government also states that Banyuasin regency is the second-largest carbon emitter of land-based sector in

Judul: Estimation of Mangrove Carbon Sequestration Based  on Environmental Characteristics in the Coastal Area of Tanjung Village, Sumenep,  Madura
Abstrak: Ekosistem pesisir memiliki potensi serapan karbon yang besar dan mampu menyimpannya hingga ribuan tahun. Mangrove menyerap CO2 dan mengubahnya menjadi karbon organik (karbohidrat) melalui proses fotosintesis. Oleh karena itu, penelitian perlu dilakukan untuk mengetahui potensi simpanan dan serapan karbon ekositem mangrove di pesisir Desa Tanjung, Kabupaten Sumenep, Madura. Data serapan dan simpanan karbon diperoleh menggunakan metode alometrik dan Walkley and Black. Kawasan mangrove di Pesisir Desa Tanjung memiliki luasan 13,75 ha. Spesies mangrove yang mendominasi di pesisir Desa Tanjung yaitu spesies Sonneratia alba. Stasiun 4 memiliki simpanan dan serapan karbon mangrove tertinggi yaitu 18,65 ton C/ha dan 68,39 ton CO2eq/ha. Simpanan karbon sedimen tertinggi terdapat di Stasiun 4 (35,87 ton C/ha). Mangrove Desa Tanjung mampu menyimpan karbon sebesar 491,88 ton C dengan nilai serapan karbon pada tegakan mangrove yaitu 1543,33 ton CO2eq., Coastal ecosystems have the potential to absorb large amounts of carbon and are able to store it for thousands of years. These ecosystems include seagrass ecosystems, salt marsh ecosystems and mangrove ecosystems. Mangroves absorb CO2 and convert it into organic carbon (carbohydrates) through the process of photosynthesis. Therefore, research needs to be carried out to determine the potential for carbon storage and sequestration in the mangrove ecosystem on the coast of Tanjung Village, Sumenep Regency, Madura. Allometric and Walkley and Black methods obtained carbon sequestration and storage data. The mangrove area on the coast of Tanjung Village has an area of 13,75 ha. Mangrove species that dominates Tanjung Village’s coast is Sonneratia alba. Station 4 has the highest mangrove carbon storage and sequestration, which were 18,65 ton C/ha and 68,39 ton CO2eq/ha. The highest sediment carbon storage was at Station 4 (35,87 ton C/ha). Tanjung Village mangroves were capable of storing carbon of 491,88 ton C with a carbon sequestration value in mangrove stands of 1543,33 ton CO2eq.

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.
