Judul: Pengaruh garis rekat glulam terhadap serangan rayap tanah (Coptotermes curvignathus Holmgren)
Abstrak: The condition of Indonesian forests are getting decrease resulted in the decreasing tendency of annual timber production from natural forests even in terms of quality and quantity. On the other hand the increasing in population, welfare, and technology will cause the increasing in community needs to the wood products from time to time. This issue leads to the occurrence of wood scarcity, the solution to cope with it is by replacing the usage of solid wood for construction materials with the usage of glulam (Glued Laminated Timber). According to Seng (1990), the wood is considered durable if it has a long service life (at least 20 years). The Durability of wood is important to be known because it is closely linked to its usage (Sumarni and Muslich 2007). Therefore, the glulam was tested against termites attack (Coptotermes curvignathus Holmgreen) to determine the extent of the glulam durability.

Judul: Ketahanan Delapan Jenis Produk Kayu Komposit terhadap Serangan Rayap Tanah (Coptotermes curvignathus Holmgren)
Abstrak: Wood composite products are potential products which are able to be utilized for structural and non-structural functions. However, wood composite needs resistant to subterranean termites attack because of the climate condition in Indonesia supporting the growth of these termites. The objective of this research was to analyze the resistance of eight wood composite products against subterranean termite. Wood composite products comprised of a medium density fiberboard with and without PVC coating, laminated veneer lumber (LVL), particleboard, corrugated board, plywood, MDF treated with anti termites, and treated rubberwood. Method used in this research was based on modified JIS K 1571-2004. Resistance class of plywood and medium density fiberboard (MDF) treated with anti-termite were classified into the first resistance class, which the weight losses were classified into 3.47% and 2% respectively. Rubber wood treated with boric acid treatment was classified into the second resistance class, where the weight loss of this product was 6.13%. In addition, LVL and particleboard were classified into the fourth resistance class, where the percentage of weight losses were 12.21% and 12.28% respectively. However, corrugated board, MDF with or without PVC linings were the worst (fifth) resistance class, which their weight losses percentage were 26.97%, 19.92%, and 19.80% respectively.

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.
