“…Another research conducted by Boateng et al (2006) also found that the genetic biomass plant background, the period when samples are taken and the growing environment, influence the lignin content in plants. Higher lignin component of Kemenyan Toba originated from North Tapanuli showed the prospective utilization of this wood as construction wood materials as that stated previously by Iswanto et al (2016).…”

Iswanto AH, Siregar YS, Susilowati A, Darwis A, Hartono R, Wirjosentono B, Rachmat HH, Hidayat A, Fatriasari W. 2019. Variation in chemical constituent of Styrax sumatrana wood growing at different cultivation site in North Sumatra, Indonesia. Biodiversitas 20: 448-452. Kemenyan Toba (Styrax sumatrana) is known as endemic resin-producing trees that naturally grow in North Sumatra and distributed throughout five districts within the province. Different growing site may constitute to different characteristics of the species, e.g. morphological differences, chemical constituent, bioactive substances, etc. Different characteristics of wood chemical constituent are an important factor determining further utilization and potential use of wood in wider spectrums. Information about wood chemical constituent of Styrax sumatrana growing from different site has not been determined yet. Therefore, the objective of this research was to analyze the characteristics of chemical constituent of Styrax sumatrana wood originated from North Tapanuli and Pakpak Bharat according to axial direction of stem (bottom, middle, and top). Chemical properties such as hollocelulose, α-cellulose, hemicellulose, Acid Soluble Lignin (ASL), acid insoluble lignin (AIL), and non-structural component (extractive content in ethanol benzene 1: 2 and ash content) were observed. Results showed that different growth location would yield in different wood chemical constituent. The wood chemical constituent from North Tapanuli and Pakpak Bharat were 52.72 and 69.80% (hollocelulose), 25.94 and 39.87% (α-cellulose), 26.78 and 29.92% (hemicellulose), 5.49 and 4.33% (Acid Soluble Lignin), 4.37 and 20.43% (Acid-Insoluble Lignin), 10.95 and 2.42% (extractive content), 1.37 and 0.8% for ash content.

Abstract. Iswanto AH, Tambunan J, Susilowati A, Hartono R, Darwis A. 2021. Short Communication: The resistance of Styrax sumatrana wood of varying growth sites and stem axial positions to subterranean termite (Coptotermes curvignathus) attack. Biodiversitas 22: 3192-3198. As mega-biodiversity country, Indonesia consists of a large number of flora and fauna, including wood-destroying organisms such as termites. One of the native trees known as a resin producer is Tobanese incense (Styrax sumatrana). The existence of this species has been studied for several wood properties such as physical, mechanical, and chemical properties, while its natural durability against termite attack has not been studied. As a country known as a haven for termites, the study on incense wood durability is very important for further utilization. The objective of this research was to analyze the natural durability of S. sumatrana wood from two growing locations and different stem positions using a graveyard test. The Graveyard test method was used to investigate the mass loss and percentage of damage of the sampled woods. The test sample used is 2x2x20 cm3 in size. The sample is buried as deep as 15 cm and leaving 5 cm of the part that is above the soil surface. The distance between the samples is 60 cm. The results obtained from this study indicated that the incense wood originating from Pakpak Bharat and North Tapanuli districts can be classified as durable class V (Vulnerable category) and severely damaged (E category) with the respective mass loss percentages ranging from 22.03-31.70% and 18.46-20.79% and damage percentages ranging from 86.55-96.27% and 78.02-86.32%. In conclusion, the positions of the stem and the sites where it grows caused a difference in the natural durability value of Styrax sumatrana wood. The incense wood originating from North Tapanuli District had slightly better durability against subterranean termite attacks than that from Pakpak Bharat District, although overall the samples from these two sites fell into the same durability class.

“…One of the provinces with high biodiversity is North Sumatra. It has a tropical forest area with a relatively high level of species diversity and with several local vegetation, which may be studied for their Several studies were conducted by Iswanto et al (2016) regarding the physical and mechanical properties of three species of Styrax wood originating from North Tapanuli, and the chemical composition based on the differences in the growth location of Styrax sumatrana was also studied. A study was conducted on the potential of styrax resin as an antioxidant and the cinnamic acid content found in the styrax resin of North Tapanuli (Hidayat et al, 2018;Kiswandono et al, 2019).…”

Raru is a lesser-known plant species originating from North Sumatra, Indonesia. Information on the characteristics is still limited, especially its chemical component. Therefore, this study aims to examine the chemical composition information of Cotylelobium lanceolatum, Cotylelobium melanoxylon, and Vatica pauciflora woods based on their axial log positions (bottom, middle, and top). The wood chemical analysis was performed in terms of the Indonesian National Standard (SNI) method. Furthermore, the analysis measured holocellulose, α -cellulose, hemicellulose, lignin content, alcohol benzene extractive content, the extractive substance in hot and water, and solubility in NaOH 1%. The results indicated that the species and their log axial positions affected different chemical components, which included α -cellulose, hemicellulose, and lignin of C. lanceolatum amounting to 41.88%, 19.39%, and 28.68% respectively. Meanwhile, for C. Melanoxylon, they were 42.01%, 21.11%, and 24.76% respectively; and for V. pauciflora wood, they were 42.95%, 23.24%, and 30.11% respectively. The average values of the extractive contents including the solubility in 1: 2 ethanol benzene, NaOH, and hot water for C. lanceolatum, C. melanoxylon, and V. pauciflora wood were (10.58%, 27.62%, 8.13%), (14.54%, 28.22%, 7.82%), and (10.95%, 28.60%, 7.57%) respectively. The wood species had a significant effect on chemical components including lignin, cellulose and hemicellulose, and extractive solubility in cold water. Furthermore, the axial log position had a significant effect on all the parameters of the chemical composition of the wood being tested.
