Judul: Partisipasi Masyarakat Nelayan dalam Pemanfaatan Kawasan Mangrove untuk Perikanan Tangkap di Halmahera Utara
Abstrak: Wilayah pesisir merupakan suatu daerah peralihan antara ekosistem daratan dan lautan yang memiliki produktivitas hayati tinggi. Adanya pasokan unsur hara dari daratan melalui aliran air sungai dan aliran air permukaan ketika hujan, serta tumbuh dan berkembangnya berbagai ekosistem alami seperti hutan mangrove, terumbu karang, padang lamun dan estuaria, menyebabkan wilayah pesisir sangat subur. Dengan potensi tersebut dan aksesibilitas yang mudah, wilayah pesisir dimanfaatkan untuk berbagai tujuan. Hutan mangrove merupakan salah satu ekosistem pesisir yang unik dan terdapat hampir di seluruh pantai pulau-pulau di Indonesia. Ekosistem ini mempunyai sifat dan bentuk yang khas serta mempunyai fungsi dan manfaat yang beraneka ragam bagi manusia serta makhluk hidup lainnya. Oleh karenanya, ekosistem mangrove dimasukkan dalam satu ekosistem pendukung kehidupan yang penting dan perlu dilestarikan keberadaannya. Mengingat rentannya keberadaan hutan mangrove dan peranan masyarakat yang tinggal di sekitar hutan mangrove dalam menjaga sumber daya alamnya, maka peranan masyarakat dalam menjaga kelestarian bahkan mengembangkan hutan mangrove menjadi suatu hutan lingkungan pendukung ketersediaan sumber daya alam laut menjadi begitu sangat penting. Partisipasi masyarakat dalam pengelolaan hutan mangrove di Kabupaten Halmahera Utara merupakan pokok perhatian dalam penelitian ini, mengingat daerah tersebut diduga sebagai spawning ground dan nursery ground bagi ikan julung-julung. Tujuan dari penelitian ini adalah untuk mengukur tingkat kesadaran masyarakat akan pentingnya hutan mangrove di Kabupaten Halmahera Utara; mengetahui bentuk dan besarnya partisipasi masyarakat dalam pengelolaan hutan mangrove di Kabupaten Halmahera Utara; mengetahui faktor-faktor yang mempengaruhi partisipasi masyarakat dalam pengelolaan hutan mangrove di Kabupaten Halmahera Utara; merumuskan kebijakan yang dapat diambil dalam pengelolaan hutan mangrove di Kabupaten Halmahera Utara. Hasil pengamatan di 3 lokasi ditemukan hutan mangrove yang cukup lebat, dan ditemukan 9 spesies yaitu: Rhizophora apiculata, R. stylosa, Sonerita alba, S. caseolaris, Bruguiera gymnorrhiza, B. cylindrica, Ceriops tagal, Exoecaria agalloca dan Avicenia sp. Hasil pengamatan vegetasi mangrove di lokasi penelitian dapat disimpulkan bahwa pada ketiga lokasi penelitian, hanya Pulau Tagalaya memiliki ekosistem mangrove yang sangat baik, lebih baik dari kedua lokasi lainnya yaitu Galela Utara dan Desa Mawea. Hal ini karena Pulau Tagalaya merupakan Kawasan Konservasi laut untuk terumbu karang dan mangrove....dst

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.
