Judul: Ketahanan Papan Komposit dari Limbah Kayu dan Karton Gelombang terhadap Serangan Rayap Tanah (Coptotermes curvignathus Holmgren)
Abstrak: This research was designed to determine the level of composite boards resistance against subterranean termites C. curvignathus. The composition of the adhesive between the water-based polymer isocyanate (WBPI) and melamine-formaldehyde (MF) were 1:0, 1:4, 0:1, and paraffin content of 0, 4, 8% based on oven dry particle and corrugated carton. The produced composite boards consisting of three layers. The face and back layers made of corrugated carton waste and the core layer was made of wafer wood waste. The board target density was 0.7 g cm-3. The board was hot pressed at 170 ºC with specific pressure of 25 kgf cm-2, for 12 minutes. The composite boards resistance were tested according to Japanese Standard JIS K 1571:2004. Research results show that B8 type composite board (WBPI-MF were 1:4 and paraffin content of 8%) performed the best result compared to the other types. B8 type composite boards can be determined as the optimum conditions for the composite board production made of wood waste and corrugated carton.

Judul: Ketahanan Papan Komposit dari Limbah Kayu dan Anyaman Bambu Betung (Dendrocalamus asper (Schult f.) Backer ex Heyne) Terhadap Serangan Rayap Tanah (Coptotermes curvignathus Holmgren).
Abstrak: Di masa mendatang bahan baku papan komposit sangat bervariasi sebagai akibat dari kekurangan bahan baku kayu yang diiringi dengan meningkatnya kebutuhan kayu oleh masyarakat. Pemanfaatan limbah kayu dan bambu sebagai bahan baku papan komposit merupakan salah satu alternatif pemecahan masalah kekurangan bahan baku kayu berkualitas tinggi. Seri penelitian pengembangan papan komposit dari limbah kayu dan anyaman bambu yang telah dilakukan selama tiga tahun terakhir oleh Massijaya & Hadi (2008) telah menunjukkan hasil yang sangat baik ditinjau dari sifat fisis dan mekanis. Namun demikian, ketahanannya terhadap faktor perusak biologis (rayap tanah) belum diketahui. Oleh karena itu, penelitian ini dirancang untuk menghasilkan papan komposit berkualitas tinggi ditinjau dari aspek ketahanan terhadap faktor perusak biologis (rayap tanah). Untuk mencapai tujuan tersebut, maka dilakukan modifikasi perekat yang digunakan serta penambahan parafin dalam proses pembuatan papan komposit.

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.
