Judul: Pengaruh Kadar Perekat MDI dan Kombinasi Strand terhadap Sifat Fisis Mekanis Oriented Strand Board Campuran Tiga Jenis Kayu Cepat Tumbuh.
Abstrak: Hutan tanaman industri menghasilkan jenis kayu cepat tumbuh (fast growing species) seperti kayu afrika, mangium, sengon, dan lain-lain. Penanaman hutan tanaman industri secara monokultur menyebabkan mudah diserang hama penyakit. Salah satu cara menghindari hal tersebut adana penanaman secara polikultur. Namun hal ini menyebabkan ketersediaan bahan baku menjadi terbatas setiap jenisnya.Untuk itu perlu upaya untuk meningkatkan efisiensi penggunaan kayu tersebut, salah satunya dengan mencampur beberapa jenis kayu dalam pemanfaatannya sebagai bahan baku papan komposit Oriented Strand Board (OSB).

Judul: Pengaruh kadar perekat MDI dan kombinasi strand terhadap sifat fisis mekanis Oriented Strand Board dari tiga jenis bambu dengan perlakuan pendahuluan perendaman air dingin
Abstrak: Forestry industry is currently experiencing a high slump. This evidenced by the number of industries that shortages supply of raw materials to meet production. Demands of solid wood raw material has been very difficult to find. Therefore, Many of the forestry industry ultimately close out of business. Nowadays, introduced a new innovation of materials and technology of composite product, OSB (Oriented Strand Board). OSB is a structural composite board product produced from the strand-shaped particles and waterproof thermosetting adhesive. OSB is very effective in overcoming the problems of the forestry industry because the raw material criteria is acquired easely, that is using low density wood and small diameter logs. However, the context of natural resources fin efficiency of wood, bamboo have lignoselulosa compound is one of the potential resources that can be used as a raw material substitute for wood in the manufacture of OSB. The variables this study consisted of combination three types of bamboo and levels MDI adhesive. Bamboo that used are Andong, Betung, and Ampel which the code of each row are A, B, and C. OSB board combination consist of two types of bamboo which one kind bamboo as face and back layers, and another one kind as core layer the racio of face, core and back raw is 1:2:1. OSB board made by nine combinations of AAA, ABA, ACA, BBB, BAB, BCB, CCC, CAC and CBC with adhesive consists of concentration levels of 3%, 4% and 5%. Physical properties and mechanical parameters observed included density, moisture content, water absorption, thickness swelling, Modulus Of Elasticity (MOE), Modulus Of Rupture (MOR), adhesion strength (internal bond) and screw holding power. After the OSB boards are sorted in the importance of value, the results of a combination of CBC (Ampel, Betung, Ampel) at 5% adhesive content is the lowest OSB value that is recommended as OSB board with the best quality when compared with the characteristic of OSB properties to other combination of strands and adhesive concentration. But in the efficiency of production cost, the right alternative combination is the combination of CAC (Ampel, Andong, Ampel) with adhesive levels of 3%.

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.
