Abstrak: The objective of this research was to analyze the natural durability of 12 woods species grown in Mount Walat Forest Education, Bogor Agricultural University against subterranean termite (Coptotermes curvignathus Holmgren) and dry wood termite (Cryptotermes cynocephalus Light). Sapwood and heartwood parts of bungur, jabon, puspa, simpur, tanjung, agathis, mahoni, pasang, sungkai, krey payung, and salam with diameter in the range of 15-35 cm were used in this experiment. Assessment of natural durability of wood against termite attacked referred to SNI 01.7207-2006. The results indicated that the weight losses of woods were varied among species and wood part. Sap and heartwoods of filicium, sapwood of bungur, pasang, and heartwood of simpur, and mahoni had the highest natural durability against C. curvignathus (2nd class). Sap and heartwood of salam, heartwood of bungur, puspa, tanjung were classified to 3rd class. Sap and heartwood of pinus, sungkai, sapwood of simpur, mahoni, puspa, tanjung and heartwood of pasang were classified to 4th class. Sap and heartwood of agathis, jabon, and pinus had the lowest natural durability against C. curvignathus (5th class). Almost all parts of 12 woods species tested belonged to 1st class against C cynocephalus except sapwood of agathis, pinus, and jabon belonged to 2nd class

Judul: Wood Decomposers in Six Community Wood Species at Two Locations
Abstrak: Kayu memiliki hubungan erat dengan rayap dan jamur sebagai dekomposer. Penelitian ini bertujuan menganalisis jumlah kayu terserang rayap dan jamur pada enam jenis kayu rakyat selama enam bulan pengujian pada dua lokasi berbeda, menganalisis tingkat kerusakannya, serta mengidentifikasi spesies rayap dan jamur yang menyerangnya. Penelitian dilakukan pada dua lokasi, yaitu Arboretum Fakultas Kehutanan dan Lingkunan IPB serta permukiman di Bogor Asri, Kecamatan Cibinong, Kabupaten Bogor. Kayu yang diuji adalah Acacia mangium, Falcataria moluccana, Anthocephalus cadamba, Maesopsis eminii, Pinus merkusii, dan Hevea brasiliensis. Pengujian dilakukan berdasarkan ASTM D 1758-06. Jumlah kayu terserang meningkat seiring dengan lama waktu pengujian dan serangannya di arboretum (75%) lebih tinggi dibanding di permukiman (39,4%). Tingkat kerusakan kayu tertinggi di arboretum adalah kayu karet (35,4 g) sedangkan di permukiman adalah kayu pinus (18,9 g). Jenis rayap tanah yang ditemukan adalah Macrotermes sp., Microtermes sp., Schedorhinotermes sp., dan Odontotermes sp. Jenis jamur pelapuk yang ditemukan adalah Aspergillus sp., Mucor sp., Trichoderma sp., Gliocladium sp., Mycelia sterilia, dan cendawan merah., Wood has a close relationship with termites and fungi as decomposers. This study aims to analyze the frequency of termite and fungal attacks on six community wood species during six months testing period at two different locations, to analyze the intensity of wood damage, and to identify the species of termites and fungi that attack them. The research was conducted at two locations, namely the Arboretum of the Faculty of Forestry and Environment of IPB and the settlement area in Bogor Asri, Cibinong District, Bogor Regency. The woods tested were Acacia mangium, Falcataria moluccana, Anthocephalus cadamba, Maesopsis eminii, Pinus merkusii, and Hevea brasiliensis. The tests were carried out according to ASTM D 1758-06. The frequency of attacks increased with the length of time of testing and the attacks were higher in arboretum (75%) than in settlement (39,4%). The highest intensity of wood damage in the arboretum was rubber wood (35,4 g); in settlements, it was pine wood (18,9 g). The subterranean termites found were Macrotermes sp., Microtermes sp., Schedorhinotermes sp., and Odontotermes sp. The rot fungi found were Aspergillus sp., Mucor sp., Trichoderma sp., Gliocladium sp., Mycelia sterilia, and red fungi.

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.
