Judul: Willingness to pay masyarakat terhadap perbaikan ekosistem hutan mangrove Muara Angke, Jakarta Utara melalui pendekatan contingent valuation method(CVM) dengan analisis regresi logit
Abstrak: Pada wilayah pesisir Indonesia terdapat ekosistem hutan mangrove yang sering disebut sebagai hutan bakau dan hutan payau. Istilah hutan bakau umum digunakan di Indonesia karena sebagian besar hutan mangrove ditumbuhi oleh jenis bakau dan tinjang (Rhizophora mucionata). Pada hutan mangrove, tumbuh pula jenis Avicennia marina, A. alba, Brugulera gymnorhiza, B. cylindrica, Phizophora mucionata, R. apiculata, R. stylosa, Sunneatia albu, dan S. caseolaris. Pada kawasan Hutan Mangrove di Muara Angke Jakaria Utara, sebagian dari hutan mangrove dijadikan areal pemukiman elite oleh pihak pengembang Pantai Indah Kapuk (PT Mandara Permai), sedangkan sebagian lagi dikelola oleh Balai Konservasi Sumber Daya Alam (BKSDA). BKSDA merupakan lembaga yang terpisah dari Perhutani meskipun berada di bawah naungan departemen yang sama, yaitu Departemen Kehutanan. Areal Hutan Mangrove Muara Angke (HMMA) Jakarta Utara yang tersisa di sekitar perumahan Pantai Indah Kapuk direncanakan oleh pihak BKSDA akan dijadikan kawasan wisata mangrove, sebagai salah satu upaya untuk mempertahankan kelestarian ekosistem hutan mangrove yang tersisa. Satu hal yang menarik, meskipun kondisi kawasan HMMA sekarang masih belum diadakan perbaikan- perbaikan yang serius untuk menuju kawasan wisata mangrove, kawasan HMMA cukup menarik minat masyarakat untuk dikunjungi sebagai alternatif tempat wisata termurah di daerah Jakarta Utara, karena setiap orang bisa keluar masuk kawasan HMMA dengan mudahnya. Contingent Valuation Method (CVM) sebagai salah satu teknik untuk menilai kualitas lingkungan dari segi manfaat, menggunakan pendekatan secara langsung yang pada dasarnya menanyakan kepada masyarakat berapa besarnya maksimum Willingness to Pay (WTP) untuk manfaat tambahan dan/atau berapa besarnya maksimum Willingness to Accept (WTA) sebagai kompensasi dari kerusakan barang lingkungan. Namun, dalam penelitian ini cara pendekatan yang digunakan adalah pendekatan WTP. Berdasarkan kondisi kawasan HMMA tersebut, maka penelitian ini bertujuan untuk: (1) Mengidentifikasi dan menganalisis nilai keberadaan dari ekosistem hutan mangrove dan aspek sosial ekonomi dari responden yang berada di Hutan Mangrove Muara Angke, Jakarta Utara, (2) Menganalis tingkat hubungan (asosiasi) antara frekuensi kunjungan, dan besarnya nilai WTP dengan variabel-variabel yang diduga mempengaruhi frekuensi kunjungan dan besarnya nilai WTP dari responden HMMA Jakarta Utara (3) Memformulasikan penilaian ekonomis mengenai besarnya nilai Willingness to Pay (WTP) masyarakat melalui pendekatan Contingent Valuation Methods (CVM) dengan analisis regresi logit terhadap perbaikan kualitas ekosistem HMMA Jakarta Utara. ...

Judul: Penilaian Ekonomi Lingkungan Terhadap Konversi Hutan Mangrove Menjadi Tambak dan Pemukiman (Studi Kasus di Hutan Angke Kapuk Jakarta Utara)
Abstrak: The conversion of the mangrove forest in Angke Kapuk done by government, private sector and the community has degraded the quality of the environment of the mangrove forest. Therefore, the purpose of this research is to 1) calculate the total economic values of the forest mangrove, and analyze the social and economic aspects of the community around the Angke Kapuk; 2) calculate and analyze the willingness to pay from the Pantai Indah Kapuk community and the willingness to accept from the community of the fish pond owners ; 3) analyze the factors which have an effect on the willingness to pay from the Pantai Indah Kapuk community and the willingness to accept from the community of the fish ponds owners. Results from the research show that the total economic value of the Angke Kapuk mangrove is Rp. 4.184.566.038,- per annum or Rp. 73.418.378,- per hectare per annum. The total economic value of the Angke Kapuk forest, which was as wide as 1154,88 hectares before it was converted by PT. Mandara Permai, was Rp. 84.789.416.385,- per annum. The amount of money willingly paid by the community of Pantai Indah Kapuk is Rp. 165.440.880,- per annum and the amount of money willingly accepted by the community of the fish pond owners is Rp. 1.329.745.043,-. The willingness to pay from the Pantai Indah Kapuk community for the improvement of the quality of the environment is affected by the people’s occupations, educations, incomes, and size of households. The amount of money willingly paid by the Pantai Indah Kapuk community is affected by their ages, educations, incomes, and size of households. The willingness to accept from the community of the fish pond owners for the improvement of the environment is affected by their educations, incomes, and size of households. The amount of money willingly accepted by the community of the fish pond owners is affected by their incomes, educations, expenditures, and size of households. The actions and efforts done to improve the environment and to manage the Angke Kapuk forest areas include: 1) the replanting of the mangrove plants; 2) the building of embankments as wave breakers; 3) the handling of plastic and household waste; and 3) the handling of illegal fish ponds within the forest areas.

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.
