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: Keanekaragaman dan Komposisi Species Semut (Hymenoptera: Formicidae) pada Vegetasi Mangrove Kabupaten Kolaka, Sulawesi Tenggara dan Muara Angke, Jakarta:
Abstrak: Salah satu kelompok fauna yang memiliki kelimpahan tertinggi pada filum Arthropoda adalah kelompok serangga. Serangga merupakan fauna avertebrata yang memiliki peranan penting dalam berbagai ekosistem. Salah satu kelompok serangga yang memiliki peranan ekologi yang sangat penting adalah semut (Hymenoptera: Formicidae). Semut merupakan serangga eusosial yang penyebarannya sangat luas dan dapat ditemukan pada berbagai habitat mulai hutan tropis, padang rumput dan beberapa habitat lainnya. Semut memiliki keanekaragaman yang tinggi dan memiliki kemampuan adaptasi sehingga keberadaannya dapat ditemukan disemua habitat . Selain pada daerah teresterial semut juga dapat ditemukan di daerah pesisir pantai karena terdapat habitat yang memungkinkan keberadaan semut yaitu vegetasi mangrove antara lain Sonnerafia, Rhizophora dan Bruguiera. Kabupaten Kolaka dan Muara Angke adalah sebagian dari daerah pesisir pantai di Indonesia yang memiliki vegetasi mangrove. Kedua wilayah tersebut diduga memiliki keragaman semut yang cukup tinggi dan berbeda. Perbedaan yang terjadi disebabkan kondisi habitat dan faktor lingkungan. Oleh karena itu kedua daerah tersebut dijadikan lokasi penelitian. Pada vegetasi mangrove Kabupaten Kolaka lokasi pengambilan semut dilakukan pada tiga stasiun yaitu pada stasiun Latambaga, Samaturu dan Wolo, sedangkan pada vegetasi mangrove Muara Angke dilakukan pada satu stasiun yaitu pada kawasan Suaka Margasatwa Muara Angke (SMMA).

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.
