Judul: Keanekaragaman Serangga di Ekosistem Mangrove: Studi Kasus Hutan Mangrove di Kawasan Pesisir Angke Kapuk, Jakarta Utara
Abstrak: Mangrove is the habitat of various insects which have important function of ecosystem. However, many insect species and their functions in mangrove ecosystem have not been identified yet. This research is aimed to elucidate the species composition of mangrove in relation to the species diversity of insect. This research was conducted in three different mangrove stand in Mangrove Protection Forest of Angke Kapuk and Soedyatmo highway mangrove area. They are monoculture stand of A. marina, mixed stand of A. Marina and R. mucronata, and mixed stand of S. alba and R. mucronata. Sampling was collected by using line quadrat method. There were eight quadrats (10 m × 10 m) suspended at every mangrove stand. Incest traping was using yellow-pan trap method. The result indicates that the mixed stand A. Marina and R. mucronata has the highest value of insects abundance. The dominant insect at every mangrove stand were order of Diptera.

Judul: Studi keanekaragaman serangga permukaan tanah pada berbagai tegakan mangrove
Abstrak: Hutan mangrove merupakan suatu ekosistem yang khas dan memiliki banyak kegunaan. Dalam bentuk fisik, ekosistem hutan mangrove menyumbangkan jasa yang penting bagi lingkungan, misalnya menahan laju abrasi pantai, menyimpan nutrisi, serta menyaring polutan. Mangrove juga merupakan ekosistem tempat hidup dan berlindungnya berbagai jenis biota yang dapat dimanfaatkan manusia untuk berbagai kepentingan. Jenis-jenis fauna mangrove pada umumnya masih dimanfaatkan sebatas sumber pangan. Sebaliknya beberapa jenis flora sudah dimanfaatkan secara langsung untuk kegunaan lain, misalnya sebagai kayu bakar, chip, dan bahan pewarna. Penelitian mengenai fauna di mangrove jauh tertinggal dibandingkan dengan floranya Inventarisasi fauna masih terbatas pada beberapa kelompok yang menonjol seperti ikan, mamalia, burung, moluska dan udang, sedangkan kelompok fauna lain seperti serangga, kepiting, dan cacing behim banyak diungkapkan (Suhardjono dan Adisoemarto, 1999). Oleh karena itu diperlukan penelitian untuk memperkaya pengetahuan keanekaragaman serangga tanah di mangrove. Penelitian dilaksanakan dengan tujuan untuk mengkaji keanekaragaman serangga permukaan tanah pada berbagai tegakan hutan mangrove. Pemilihan topik serangga tanah berdasarkan pemikiran baliwa serangga tanah memiliki berbagai peranan penting dalam menjaga keseimbangan ekosistem, antara lain sebagai dekomposer dan penyubur lahan. Di samping itu serangga tanah juga memiliki keanekaragaman yang tinggi. Penelitian ini dilakukan di hutan mangrove yang dikelola dengan sistem tambak tumpangsari di RPH Tegal Tangkil, BKPH Ciasem, KPH Purwakarta, Perum Perhutani Unit III Jawa Barat. Lokasi penelitian dilakukan di tegakan Avicennia marina dan Rhizophora mucronata dengan umur tanam yang berbeda, yaitu (1) tegakan A. marina tahun tanam (tt) 1980, (2) tegakan A. marina 11 1990, 3) tegakan R. mucronata tt 1980 dan (4) tegakan R. mucronata tt 1990....

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.
