“…The teakwood from Muna Island has been popular for wooden furniture industries since the Dutch colonial era (Fendi et al, 2017). Alongside its function as raw material for furniture manufacturing, the wood is also used for building components and others (Lempang and Asdar, 2007).…”

Muna teakwood, especially from old stands, has been popular as raw material for timber industries in Indonesia for the past ten decades. Due to the scarcity of this wood, superior-grown seedlings of Muna teakwood have been developed and widely planted. Since there is no information on its characteristics, therefore, the aim of this research was to investigate wood characteristics of the 8-year-old superior-grown teak from Muna Island to ensure their proper utilization as raw material for wooden furniture. Wood discs and boards from basal area of three different trees were used as the samples. Macroscopic and microscopic anatomical characteristics were observed following the IAWA's list, while their physicalmechanical properties were measured following British Standard 373-57. Results showed that anatomical characteristics of this wood sample are similar to regular teakwood, but its heartwood portion is higher. Differences among trees are found in regards to wood texture, growth ring width, as well as early and latewood portion. The green moisture content was lower than that of fast-growing teak of a similar age. The wood is more stable than the old teakwood, but its specific gravity is lower. In general, mechanical properties of this wood were higher than those of the regular fast-growing teakwood, but lower than the old one. Based on its specific gravity, this superior Muna teakwood was categorized as a Strength Class of III. The wood is suitable enough for wooden furniture manufacturing.

Background: Sudan III is known red disazo dye possess a hydroxyl group which is sensitively to interact with others molecules such as CO 2 , O 2 , SO 2 through hydrogen bonding. Methods: Fabrication of Sudan III thin film for sensor technology application has been carried out by using PVD method. The physical structure that is crystallinity of this film has been investigated by using XRD method. Results: The XRD spectra of powder Sudan III shows crystalline structure while the XRD spectra of thin film results of the PVD method, which is deposited on substrate glass slide shows amorphous structure. There are no differences in the crystallinity content of Sudan III thin film that exposure to acetone and alcohol vapor. The interplanar distance of crystals plane is about 28.47 nm, the average crystallite size is about 35.6 nm and the average molecular chain separation is about 37.9 nm. Sudan III thin film result of the PVD method shows an interesting optical characteristic (absorption). There are significantly different between UV-VIS spectra Sudan III thin film compared to the UV-VIS spectra of Sudan III solution. The UV-VIS spectra of the Sudan III thin film shows a decreasing of peak intensity in visible wavelength which indication of orientation effect of molecule on substrate surface. The aborption peak at UV region for Sudan III thin film shows a shifting to the long wavelength compared to the Sudan III in form of solution.
