Judul: Wood component properties changes, wood cell structure and base properties densified wood to partially
Abstrak: Wood densification is a treatment that applicable to increase quality and wood properties, either through impregnation or compression. Until now, it was carried out comprehensively, but not partially, resulting in spring back and over density problems of densified wood. Therefore, using partial densification this study will evaluate and analysis the phenomenon occurred in cellular structure and chemical components of cell wall. Wood of Mangium and Agathis representing hardwood and softwood species, respectively, were used as the sample. Several temperature levels and heating durations were used in this experiment, while compression level was only one namely 20%. Impregnation with mixture monomer solution consists of styrene (ST) and methyl methacrylate (MMA) was performed with full- and empty cell methods. The result shows that partial densification of wood both compression and impregnation methods could resulted in the increasing of physical and mechanical properties of wood by changing its cellular structure and chemical components namely cellulose crystallinity, microfibril angle, lignin relocation as well as degradation of cellulose and hemicellulose. The result densification treated of wood showed generally good termite resistance.

Abstrak: Densification or compression is one of many efforts could be employed to improve or modify wood quality. Through simple densification process applied i.e. 50% of compression level, and 20 MPa of pressure at 150 ⁰C it was shown that physical and mechanical properties of 5 year-old of fast growing teak could be improved well. Compared to those of the control wood, the properties of densified wood are much better. Its moisture content is 50.82% reduced; while the others are increased vary. Wood density is increased up to 67.92%, specific gravity increased 82.22%, MOE increased 62%, MOR increased 72%, compression strength parallel to the grain increased 77%, and wood hardness increased 107% (the highest). The densified of teak wood produced is classified to the strength class of II. The paired sample T-test result between control- and treated wood shows that all properties studied are different from each other at confidence interval of 95%.

Judul: Bakteri Flora Paling Umum Ditemukan Di Rongga Mulut Python Retikulatus Liar
Abstrak: Reticulated python is a non-venomous snake native to South and Southeast Asia. It is the world's longest snake. The purpose of this literature review study is to investigate the common bacterial flora found in oral cavity of the reticulated python. The data for this case study was obtained from several articles, journals, books and credible websites. Based on existing data, there are a wide variety of bacteria in the oral cavity of free-living reticulated pythons. The majority of the organisms were Gram-negative. Pseudomonas spp. were the most commonly isolated bacterial species, being found in 50% of the snakes sampled, and was followed by Staphylococcus sciuri.
