Abstract

Lignocellulose materials, such as bamboo, rattan, and wood, have been largely used for furniture and crafts. On the other hand, the utilization of lignocellulose-like materials, which have a similar texture and appearance to those from nature, has been increasing recently due to their superior durability. This research aimed to identify the lignocellulose-like material using spectroscopy analysis, such as Raman and Near Infrared (NIR) which is well-known as a non-destructive, quick, and accurate approach for material identification. We investigated 4 types of lignocellulose-like materials that were provided by Dewan Serat Indonesia (The Indonesian Fiber Council) from an industry that produces them. The NIR analysis was performed at wavenumbers 10,000-4,000 cm-1. The natural lignocellulose (bamboo and wood) and the polymers (polyethylene and polyproline) were used as standards. Raman analysis was further employed to identify the composition of selected lignocellulose-like materials by comparing their spectra with the library software. The results showed that the original NIR spectra of lignocellulose-like and those natural materials were different, indicating that the NIR analysis can differentiate those materials. The NIR spectra of lignocellulose-like materials were similar to those of polyethylene spectra. Those lignocellulose-like were also identified as polyethylene due to the similarity of the Raman spectra and their library spectra.

Abstract

Ear mushroom is one of edible wood rotting fungi that has been already consumed by community. Mushroom's media was made of sengon (Falcataria mollucana (1) Nielsen) sawdust with addition of 12 or 16% rice bran, 3.2% lime, 0.4% gypsum, urea or trisodiumphosphate 0.4% and water, then being composted for 1, 3, 5 and 7 days. Media samples were grouped into A and B, where sterilized media A were inoculated with brown ear mushrooms (Auricularia auriculae-judae HHBI-312, HHBI-326) and black ear mushrooms (Auricularia polytricha HHBI-318, HHBI-331), and those of media B were inoculated by black ear mushrooms (Auricularia polytricha HHBI-331). Biological Conversion Efficiency (BE) was calculated based on the ratio of the mushroom yield in fresh condition to the dry weight. Results indicated that the high yield of ear mushroom was obtained on composting media for 3 and 5 days periods. The average yield of Auricularia auriculae-judae HHBI-312, HHBI-326 on media A were 58.88 grams dan 60.51 grams (EB 10.96% and 10.92%), and for Auricularia polytricha HHBI-318, HHBI-331) were 67.5 grams and 101 grams (EB 12.38% dan 18.56%), respectively. Urea addition on the media tend to increase the BE value of A auricula-judae. Houvrer, it found that the yield and BE value of A. polytricha on media consist of urea were higher than that on media consist of trisodiumphosphate. The productivity of A. polytricha HHBI-331 on B-media added with 16% ricebran (102.06 g. BE 18.73%) revealed bigber than that which added with 12% ricebran (79.94 g. BE 17.59%). Therefore, A. auricula-judae HHBI-312 and A. polytricha HHBI-331 selected for further mushroom production.

Abstract

Capability of decaying-fungi varies according to their strains. This paper studies the decaying capability of ten fungi strains against four wood species from Manokwari. The wood samples have been exposed to the ten fungus strains using Kolle flask method as mentioned in SNI 7207: 2014. Scrutiny results revealed that two of ten fungus strains were categorized as low decaying capability, which comprised of Chaetomium globosum and Lentinus lepideus. Meanwhile, four strains were classified as moderate decaying capability which were Schizophyllum commune, Trametes sp. HHBI-379, Trametes sp. HHBI-332, and Phlebia brevispora. The remaining four fungus strains were regarded as high decaying capability, namely Polyporus arcularius, Polyporus sp., Pycnoporus sanguineus, and Tyromyces palustris. The highest weight loss of wood occurred in the sapwood of Rhus taitensis exposed to Polyporus sp. Meanwhile, the lowest loss was obtained on the heartwood of Haplolobus sp. caused by L. lepideus exposure. Three wood species comprising Tetrameles nudiflora, Rhus taitensis, and Pimeleodendron amboinicum belonged to non-resistant wood (class IV), while Haplolobus sp. was grouped into resistant wood (Class II).

Abstract

Five wood species namely tangkalak (Litsea roxburghii Hassk.), cangkring (Erythrina fusca Lour.), kayu putih Melaleuca cajuputi Powell.), ki tanab (Zanthoxylen rhetsa DC.), and huru leneur (Sterculia cordata Blume), were evaluated based on their metal corrosion properties using jam-pot methods. Wood samples were extracted from two tree stands, divided radially into three groups, namely outer, middle and inner part of log. The results showed that iron corrosion was found in all wood species. The corrosion intensities were identified by the weight loss of the attached metal screws. Higher corrosion rates were found on samples of kayu putih. The highest weight loss of screw was found on kayu putih samples extracted from midle part (B part) of P-II tree, i.e. 2.76%. The lowest weight loss of screw was encountered on tangkalak wood samples extracted from inner part (C. part) of P-Il tree. The percentage of samples weight loss on tree-1 was lower (0.55%) than that on tree-11 i.e. 0.72%. Comparing those two sample groups, the weight loss of outer part (A) and inner part (C) were lower than that of the middle part of logs.

Abstract

Currently, the availability of red meranti, kulim and mersawa wood is commonly used as raw material for “jalur” constructionin Kuansing Regency, Riau Province, are increasingly scarce, while the need is getting higher. Accordingly, it is necessary to choosealternative wood types that have similar strength and durable properties compatible with red meranti, kulim and mersawa wood tomeet specifications for the “jalur” construction. This paper studies the effectiveness of preservative treatment by infusion techniqueand bandage use against dry wood termite. Balam (Macaranga conifera Muell. Agr.) was chosen as alternative wood for makingthe path because currently this wood is abundant but not much used for making pathways. The results of field observations indicatedry-wood termites attacke the path stored on land, so it is necessary to preserve the path so that they are not attacked by wooddestroying organisms, particularly the dry-wood termites. Preservation treatments on standing trees using complex boron compoundsby infusion and bandage techniques were examined to increase the durability class of balam wood. Testing of dry-wood termiteattack was carried out according to the SNI 7207-2014 method. The data were processed using a completely randomized factorialdesign. The analysis results showed that the preservation by infusion and bandage techniques was significantly different in terms ofweight reduction and mortality of termites. Observation on the degree of attack visually on the control and infusion technique was40 (hold) lower than the bandage technique 70 (moderate). The highest mortality in infusion technique was 90.67% compared tocontrol 86.08%, and the bandage was 61.75%. Preservation using the infusion technique showed a higher boron content comparedwith the bandage technique.

Abstract

The resistance of six wood species against eight strains of destroying fungi was studied. Six wood species of ketapang (Terminalia complanata K. Sch.), pala hutan (Gymnacranthera paniculata Warb.), bipa (Pterygota horsfieldii (R.Br.) Kosterm.), kelumpang (Sterculia shillinglawii), manggis (Pentaphalangium parviflorum) and lancat (Mastixiodendron pachyclados Melch.), wereobserved using Kolle-flask methods. Wood samplesof inner and outer parts of the log were prepared from each species. Results show that M. pachyclados is classified as resistant (class II), P. horsfieldii is moderately resistant (class III), while the other four species are not-resistant (class IV) against destroying fungi. The average weight loss of the inner part is lower than that of the outer part logs, then both groups are classified as not-resistant wood (class IV). The lowest decay resistance is obtained from outer part of G. paniculata exposed to Pycnoporus sanguineus, while the highest decay resistance is taken from outer part of M. pachyclados exposed to Tyromyces palustris. The fungal ability to decay wood from the highest to the lowest are P. sanguineus, Polyporus arcularius, Polyporus sp., T. palustris, Schizophyllum commune, Lentinus lepideus, Phlebia brevispora, Chaetomiumglobosum, respectively.

Abstract

Lesser-known wood originating from rain-forests is an alternative raw material for the national timber industry.Optimizing this wood group’s utilisation requires information on its resistance to the decaying fungus attack of eachwood species used. This research is studying the resistance of five wood species from West Kalimantan, and the rusttest was carried out on the metal embedded in heartwood and exposed to fungus using the Kolle-flask method. NaOH’swood-solubility analysis referred to ASTM D-1110-84’s Standard. Results revealed that Albizia sp. and Syzygiumsp. belonged to resistant woods (class II); Santiria sp. and Lithocarpus ewyckii belonged to moderately-resistant(class III); while Xanthophyllum excelsum belonged to not-resistant (class IV). The greatest weight loss occurredat sapwood of Xanthophyllum excelsum being exposed to Pycnoporus sanguineus. Average weight loss atheartwood (with class II) was lower than that at sapwood (class III). The greatest weight loss of woods embedded byscrews occurred at screwed Syzygium sp. then exposed to Polyporus sp. The average weight loss of screwed woods wasgreater than that of unscrewed woods. Meanwhile, the highest weight loss of screws occurred at Xanthophyllumexcelsum, then at Syzygium sp., exposed to Polyporus arcularius. The greatest weight of screw-rust powder wasachieved at Syzygium sp. exposed to Polyporus arcularius. Five fungi species exhibited moderate capability, whilethree species afforded low capability in decaying woods. The effect of decaying fungi on corroding screws was entirely low.

Abstract

This study examining study fungal resistance properties of five wood species using Kolle-flask method. The studied wood species include: ki hiur (Castanopsis acuminatissima), huru pedes (Cinnamomum iners), huru koja (Litsea angulata), ki kanteh (Ficus nervosa), and kelapa ciung (Horsfieldia glabra). Samples were grouped into inner part and outer part of logs as well as metal screwed and unscrewed. Results show that all of five studied wood species no matter parts of log are classified not-resistant (class IV). Weight loss of wood samples with the attached metal screw is higher in average than the unscrewed wood samples. The highest weight loss was recorded on the inner part of unscrewed huru pedes wood exposed to Pycnoporus sanguineus. While the lowest weight loss was found in screwed samples of the same species exposed to Dacryopinax spathularia. The metal screws were found corroded after the test and the highest screw weight loss was found on ki kanteh wood. Metal screw that attached on the inner part experienced lower eight lost than screws attached on the outer part of log.
