Judul: Valuation of Mangrove Ecosystem Services in Pramuka Island as Habitat, Carbon Sequestration, and Coastal Protection
Abstrak: Mangrove merupakan ekosistem produktif yang memiliki banyak manfaat. Namun, analisis biaya manfaat tidak langsung pada jasa ekosistem mangrove sulit diperkirakan karena dinilai terlalu rendah, sehingga menyebabkan degradasi ekosistem mangrove. Penelitian ini bertujuan untuk memperkirakan nilai jasa ekosistem mangrove sebagai habitat, penyerap karbon, dan pelindung pesisir. Penelitian dilakukan di Pulau Pramuka pada bulan November 2023–Februari 2024. Penilaian ekonomi menggunakan metode pendekatan harga pasar (market price), Social Cost of Carbon (SCC), dan replacement cost. Hasil penelitian mendapatkan potensi tangkapan ikan dan udang masing-masing sebesar 60.707 kg/tahun dan 2.964 kg/tahun dengan valuasi senilai Rp 1.166.791.922/tahun. Rata-rata stok karbon mangrove yaitu 138,80 tonC/ha dengan kapasitas penyerapan karbon sebesar 509,39 tCO2/ha, sehingga menghasilkan valuasi senilai Rp 1.266.403.862/tahun. Ekosistem mangrove sebagai jasa pelindung pesisir didapatkan valuasi senilai Rp 486.857.750/tahun. Hal tersebut dipengaruhi oleh luas area, kerapatan, biomassa mangrove, jumlah produksi dan harga komoditas ikan, serta geomorfologi pesisir Pulau Pramuka., Mangroves are productive ecosystems that have many benefits. However, indirect benefit-cost analysis of mangrove ecosystem services is difficult to estimate because it is undervalued, leading to mangrove ecosystem degradation. This study aims to estimate the value of mangrove ecosystem services as habitat, carbon sink, and coastal protection. The research was conducted on Pramuka Island in November 2023-February 2024. The economic valuation used market price, Social Cost of Carbon (SCC), and replacement cost approaches. The results showed that the potential catch of fish and shrimp was 60,707 kg/year and 2,964 kg/year, respectively, with a valuation of Rp 1,166,791,922/year. The average mangrove carbon stock is 138.80 tonsC/ha with a carbon sequestration capacity of 509.39 tCO2/ha, resulting in a valuation of Rp 1,266,403,862/year. Mangrove ecosystems as coastal protective services obtained valuation worth Rp 486,857,750 / year. This is influenced by the area, density, biomass of mangroves, the amount of production and price of fish commodities, and the coastal geomorphology of Pramuka Island.

Judul: Penilaian Jasa Penyediaan dan Pengaturan Ekosistem  Mangrove di Pandansari Brebes Jawa Tengah
Abstrak: Ekosistem mangrove Pandansari, Brebes, Jawa Tengah merupakan salah satu sumberdaya alam pesisir yang potensial untuk dimanfaatkan. Ancaman alih fungsi lahan menunjukkan kurangnya kesadaran masyarakat sekitar akan pentingnya manfaat ekosistem mangrove. Penelitian ini bertujuan mengestimasi total ekonomi nilai guna langsung dari jasa provisoning dan tidak langsung dari jasa regulating ekosistem mangrove Pandansari. Metode pengambilan sampel yang diterapkan dalam penelitian ini adalah purposive sampling dengan pendekatan pengumpulan data melalui wawancara. Analisis data yang digunakan, yakni melalui pendekatan permintaan melalui metode EOP (effect on production) dan pendekatan contingen valuation method (CVM) berupa willingness to pay (WTP). Nilai ekonomi dari jasa provisioning ekosistem mangrove sebagai penyedia perikanan tangkap, yakni sebesar Rp124.401.446/ha/tahun, sedangkan nilai ekonomi dari jasa regulating ekosistem mangrove sebagai pengendali banjir, yakni sebesar Rp1.625.340.000/tahun., The Pandansari mangrove ecosystem in Brebes, Central Java, is one of the coastal natural resources with potential for utilization. The threat of land-use change indicates a lack of awareness among the local community about the importance of the mangrove ecosystem's benefits. This study aims to estimate the total economic value of direct use from provisioning services and indirect use from regulating services of the Pandansari mangrove ecosystem. The sampling method applied in this research is purposive sampling with a data collection approach through interviews. The data analysis used, is the demand approach through the Effect on Production (EOP) method and the Contingent Valuation Method (CVM) in the form of willingness to pay (WTP). The economic value of the provisioning services of the mangrove ecosystem as a provider of capture fisheries is Rp124,401,446/ha/year; while the economic value of the regulating services of the mangrove ecosystem as a flood controller is Rp1,625,340,000/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.
