DOI: The aim of this research was to evaluate the toxicity of technical-grade chromated-boron salts formula against wood termites and wood rotting fungi. Wood samples were preserved using vacuumpressure methods with 5 different concentrations. For the test against subterranean termites, 25 mm x 25 mm x 5 mm preserved wood samples were put in containers previously filled with humid sand media and termites.

Wood destroying fungi lives off wood components, such as cellulose, hemicellulose and lignin which are biochemically overhauled with the help of enzymes. Well know wood in the trade to date approximately types. For instance Falcatria molucana, Acacia mangium dan Pinus merkusii Yunasfi Kinds of it which potentially most decaying off the woods are Schizophyllum commune, Pleurotus ostreatus and Pleurotus djamor.
This study aims to determine the potential that three kinds on wood decay fungi and the potential quality of wood to three decay fungi based on JIS K method. The results showed that all three types of wood rot fungi used in this test has the potential to lower the weight of the wood sample.
Fungi are the most potent in lowering weight sengon is S. Fungi significantly affect the percentage reduction in timber weight, the percentage weight loss of wood obtained from the results of laboratory tests the durability of wood used as a parameter.
From these results it sengon wood into class II resistant , while according to the Seng sengon wood balance to class IV—V not resistance so it can be said that this research has not succeeded.
Discrepancy value of the percentage reduction in weight of wood sample with literature, because they suspected the existence of fungal hyphae into the sample wood so that hamper the final weight after the test sample is fed finished. Based on visual observations indicate multiple replication miselliums of fungi not full to close the wood.
Ganerally the sample timber has been attacked fungal discoloration lighter light brown. Its shows three types of fungi that is used is a white rot fungi.

Space truss is a three dimensional structure, which can draw forces work on its member either tension or compression without torsion. Space truss is favorable to build a large, light and stiff structure, which are made from relatively short bars. This research is a feasibility study of using bamboo as space truss members. This study focuses on designing bamboo connection, that strong enough for both tension and compression. According to the analysis done, bamboo culm with diameter 4 cm and 6 cm could be use to make space truss member for a simple 3m x 4 m canopy structure.
