Abstract

The aim of the study was to analyze the content of pelawan wood extractive substances (Tristaniopsis whiteana (Griff)) and to test it with the fungi Schizophyllum commune Fr and Pleurotus ostreatus. Pelawan heartwood powder was macerated with methanol. Then fractionated in stages with n-hexane, chloroform, ethyl acetate, and butanol. The resulting extract was then tested with S. commune and P. ostreatus fungi. The most active fraction was isolated using column chromatography with a gradient system, the eluent was methanol:chloroform. Sub-fractions were then tested for fungi to determine the most active sub-fractions, and the most active sub-fractions were then analyzed by 1H NMR. The results showed that the extractive content of pelawan wood was most soluble in chloroform. All extract fractions contain potential as anti-fungal. .The chloroform fraction was very active compared to the other fractions. Isolation of the chloroform fraction by column chromatography obtained 8 sub-fractions. All of these sub-fractions were able to inhibit the growth of S.commune and P.ostreatus with IC(50) = 54.55 - 64.69 mg/L and IC(50) = 54.17 - 64.44 mg/L respectively. PL.3 sub-fraction was the most active among the 8 sub-fractions. The results of 1H NMR analysis on the PL.3 subfraction were shown to be Heptanoic Acid compounds.

Abstract

The microfibril angles (MFAs), relative crystallinity index (RC), and crystallite width (CrW) of compression wood (CPW), lateral wood (LTW), and opposite wood (OPW) in Agathis (Agathis loranthifolia) and Sumatran Pine (Pinus merkusii) stem wood were observed and compared to obtain valuable information on wood quality for effective utilization. The iodine staining method and optical microscopy were applied to measure the MFA in the tangential section. RC and CrW were analyzed with an X-ray diffraction technique. CPW had the largest MFA and the smallest RC in both species. In Agathis, LTW and OPW had comparable MFA, RC, and CrW, whereas the CrW of CPW was the smallest. In Sumatran pine, there was a significant difference in MFA and RC between LTW and OPW. CPW, LTW, and OPW showed comparable CrW. The MFA decreased and RC increased from near the pith to bark in both species. The CrW increased from near the pith to the bark of Sumatran pine, whereas it was constant in Agathis. In conclusion, MFA and RC could be used to identify CPW, LTW, and OPW in both species. There were distinctive MFA and RC properties between reaction wood in both species. Keywords: Agathis loranthifolia, crystalline properties, microfibril angles, Pinus merkusii, reaction wood

Abstract

The objective of this study was to assess the properties of cross-laminated timber (CLT) fabricated from the combination of Sumatran pine (P) and coconut trunk (C) bonded with polyurethane adhesive. The basic properties of raw materials and adhesives were characterized. The CLT panels’ length, width, and thickness are 100 cm by 30 cm by 3.6 cm, respectively. Three-layer CLT was made with 4 combinations of face/core/back lamina, i.e., PPP, CCC, PCP, and CPC, which are arranged perpendicular to each other. The laminae were bonded using PU adhesive on 160 g.m-2 glue spread. The CLT’s delamination and wood failure percentages (WFP) were assessed following the JAS 3079 (2019) standard. The study’s results demonstrated that the PU adhesive employed in this investigation could curl ideally at 30°C for 200 min. Solid pine and coconut’s physical and chemical characteristics differed, but their wettability to polyurethane adhesives was identical. Hybrid pine CLT has greater attributes compared to single pine CLT. Single coconut CLT, on the other hand, offers better features than hybrid coconut CLT. All CLT samples failed to fulfil the JAS 3079 (2019) requirement for delamination (=< 10%) and WFP (>= 90%).
