Abstrak: INTRODUCTION. Total destruction of forests by 2005 is estimated up to 59.1 million ha. To overcome the problem, government through the Forestry Department launched an industrial forest program and plantation forest program. Industrial forest program development is generally higher priority to meet the needs of raw materials for pulp and paper industry. Plantation forest timber generally has short sortimen, small diameter, high ratio of juvenile wood and mature wood. From these characteristics can be concluded that the plantation forest timber, unsuitable for construction raw materials. So that the plantation forest timber with these characteristics can be utilized for the furniture industry raw materials. Some specific criteria of the furniture industry raw materials are a beautiful pattern on the wood. Appearances pattern on the wood are closely related to the constituent of wood anatomical structure. This study aimed to observe the kind of anatomical structures that caused the appearance of decorative figure.

Judul: Kajian sifat pemesinan kayu kelapa sawit (Elaeis guineensis Jacq.) sebagai bahan bangunan dan furniture
Abstrak: Seiring dengan pesatnya pertumbuhan penduduk di Indonesia, secara tidak langsung akan meningkatkan pula kebutuhan kayu untuk bahan bangunan dan furniture. Data dari Biro Perencanaan Departemen Kehutanan 1997, pada tahun 2000 diperkirakan kebutuhan kayu meningkat sampai 80 juta m³ per tahun, sedangkan ketersediaan kayu bulat pada tahun 2000 diperkirakan hanya 49.01 juta m per tahun. Dari data tersebut dapat dilihat bahwa kebutuhan bahan baku industri perkayuan dalam negeri mengalami kekurangan. Salah satu alternatif usaha dalam menanggulangi masalah tersebut adalah mencari dan memanfaatkan biomassa kayu lainyya yang mempunyai potensi yang besar, diantaranya adalah kayu kelapa sawit (Elaeis guineensis Jacq.). Penelitian ini bertujuan untuk mengetahui kualitas/sifat pemesinan kayu kelapa sawit dalam rangka mengetahui Leknik pemesinan yang tepat serta mencari upaya-upaya perbaikan kualitas. Dengan sasaran terakhirnya adalah termanfaatkannya kayu sawit sebagai bahan bangunan dan furniture.

Judul: Pengujian Virus Newcastle Disease Gen VII Isolat Lapang Sebagai Virus Standar Pada Uji Tantang Vaksin
Abstrak: This study was conducted to determine the standard of Newcastle disease virus Gene VII field isolate as a virus challenge to vaccine test. A virus suspension that has previously been tested by HA test then titrated with EID50 using 30 Specific Pathogen Free (SPF) of 10 day old chicken embryonated eggs. In addition, chicken lethal dose50 (CLD50) test were used to determine the virus titer that could cause 50% death of the chicken population. The CLD50 test was used 25 day-old-chickens (DOC) divided into 5 groups. The virus was diluted from 10-1 to 10-8. The 104 to 10-8 dilution of NDV was infected to every group of chicken via eyedrop and intranasal with 0.1 ml/chicken dosage. Haemagglutination test showed that the allantoic fluid were contain high titers of NDV is 512 HAU. The infective NDV that had been titrated by EID50 test showed the virus titers is 109 EID50/0.1 ml or 1010 EID50/ml and the virus titers of CLD50 test e.i 106.48 CLD50/0.1 ml or 107.48 CLD50/ml. These results can be concluded that the NDV Gene VII field isolates were most appropriate to be used as a standard virus to vaccine test
