Abstract

Wood anatomy of Shorea mujongensis P.S. Ashton was investigated in order to ensure this species belongs to yellow meranti group. Such study is very important since this species is already listed in the red list of IUCN and classified as critically endangered species. The microscopic slides were prepared according to the Johansens method, while the anatomical features observed according to the IAWA  List. The results show that S. mujongensis wood exhibit brown heartwood, light brown sapwood, rough texture, straight grain sometimes interlocked and somewhat rough. The main microscopic characters are growth rings indistinct; vessel diffuse, mostly solitary, rounded to oval; simple perforation plate and alternate intervessel pits; parenchyma scanty paratracheal to thin vasicentric; axial intercellular canals in long tangential line, radial intercellular canal and vasicentric tracheids present; rays uniseriate and multiseriate, prismatic crystal in procumbent cells; fiber length 1,294 µm, diameter 26 µm and wall thickness 4µm. Macroscopic and microscopic observation of S. mujongensis wood confirms the species belongs to yellow meranti group. The assesment on fiber dimensions and derived values of the wood fibers classified the wood into class quality II. It indicates that this species is moderately favorable as raw material for pulp and paper manufacture.

Abstract

Keawetan kayu alami dinilai berdasarkan ketahanannya terhadap organisme perusak tertentu. Pengujian ketahanan alami kayu terhadap organisme perusak di laut dilakukan dengan membenamkan contoh kayu di perairan laut terbuka. Setelah enam bulan, kayu dinilai intensitas kerusakannya dan diklasifikasikan kelas ketahanannya terhadap serangan penggerek di laut. Penilaian kerusakan kayu dilakukan dengan interpretasi gambar digital. Tulisan ini mempelajari ketahanan alami sembilan jenis kayu dari Sumatera, Jawa dan Kalimantan terhadap organisme penggerek laut dengan perangkat lunak Image-J setelah enam bulan. Hasil pengujian kayu di perairan terbuka menunjukkan kayu sempur lilin (Michelia champaca L.var. pubinervia) dan kayu bawang (Azadirachta excelsa) (Jack) Jacobs) termasuk kelas ketahanan I (sangat tahan), sedangkan kayu cangcaratan (Lithocarpus sundaicus(Blume) Rehd., aveang kelalai (Shorea pervistipulata ssp. albifolia) termasuk kelas ketahanan II (tahan) terhadap penggerek kayu di laut. Kayu ki pasang (Prunus javanica Miq.) dan segelam (Hopea rudiformis) termasuk kelas ketahanan III (agak tahan) terhadap penggerek kayu di laut, sedangkan kayu ki bugang (Arthophyllum diversifolium Blume) dan ki langir (Otophora spectabilis Blume) termasuk kelas ketahanan V (sangat tidak tahan) terhadap penggerek kayu di laut. Pengukuran persentase kerusakan kayu dapat dilakukan dengan akurasi tinggi menggunakan metode gambar digital daripada cara konvensional. Pengukuran persentase kerusakan kayu dengan gambar digital menghasilkan nilai lebih tinggi karena bekas lubang tali. Namun, bekas lubang tali juga diperhitungkan sebagai kerusakan kayu. Untuk memperoleh pengukuran kerusakan yang tinggi, maka metode gambar digital dimodifikasi dengan menutup bagian lubang bekas tali dengan kesan yang sama dengan bagian disekitarnya.

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.
