Judul: Pembuatan Papan Partikel dari Bambu dengan Perekat Resin Damar.
Abstrak: Bamboo contains high fiber (59.75%), so it is potential to be used as particleboard raw material. In this study, resin of damar was used as adhesive to substitute the synthetic adhesive such as urea and phenol formaldehide.The objective of this study were to determine the effect of pressing time andamount of resin added on physical and mechanical properties of particleboard, and determine to the treatment combination to produce the particleboard with best quality. This research was designed usingRandomized Block Design with 2 factors, including pressing time (10 and 14) and amount of resin added (12, 14, 16%) with pressing temperature (130 and 150oC) as a group. The result of variance analysis at 130oC showed that pressing time affecteddensity, water adsorption 2 and 24 hours, modulus of rupture and amount of resin added affected water content, thickness swelling 2 and 24 hours. Furthermore the result of variance analysis at 150oC showed that pressing time affected water content, modulus of elasticity, modulus of rupture, internal bond and amount of resin added affected thickness swelling 2 and 24 hours, modulus of elasticity and modulus of rupture. Based on physical and mechanical, particleboardfrom the treatment of 10 min pressing time, 14% of damar resin and 150oC pressing temperature performed the best quality compared with other treatments.

Judul: The Utilization of Corn Stalks and Sembilang Bamboo as a Raw Material for Particleboard.
Abstrak: Batang jagung (Zea mays L.) dan bambu sembilang (Dendrocalamus giganteus Munro) merupakan bahan baku berlignoselulosa yang memiliki potensi sebagai bahan baku papan partikel. Papan partikel adalah produk panel yang dihasilkan dengan memanfaatkan partikel kayu atau bahan berlignoselulosa lainnya yang ditambah dengan perekat kemudian dikempa. Penelitian ini bertujuan mengetahui pengaruh jenis perekat dan komposisi bahan baku terhadap sifat fisis dan mekanis papan partikel dari batang jagung dan bambu sembilang sebagai bahan baku alternatif. Jenis perekat yang digunakan adalah urea formaldehida dan fenol formaldehida dengan kadar perekat 10% dan komposisi batang jagung:bambu sembilang adalah 100:0, 75:25, 50:50, 25:75, 0:100. Kerapatan target papan partikel adalah 0.8 g/cm3. Pengujian sifat fisis dan mekanis papan partikel mengacu pada standar JIS A 5908:2003. Hasil penelitian menunjukkan nilai kerapatan 0.79-0.84 g/cm3, kadar air 9.43-11.98%, daya serap air 33.37-48.48%, pengembangan tebal 7.85-14.08%, MOE 1347.35-2873.83 N/mm2, MOR 15.28-28.39 N/mm2, IB 0.25- 1.39 N/mm2, dan kuat pegang sekrup 285.43-560.96 N. Secara umum papan partikel dengan perekat fenol formaldehida memiliki sifat fisis dan mekanis dengan kualitas lebih tinggi daripada perekat urea formaldehida. Semakin tinggi penambahan partikel bambu sembilang maka sifat fisis dan mekanis papan partikel memiliki kualitas yang semakin tinggi. Sifat fisis dan mekanis papan partikel dengan kualitas paling tinggi dihasilkan pada komposisi bahan baku 100% bambu sembilang dengan perekat fenol formaldehida.

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.
