Abstract

Tiga pohon mahoni berumur 12, 21, dan 30 tahun diambil secara acak dan butan tanaman. Dari ketiga log kayu tersebut dibuat contoh ttji berukuran 2,5 cm x 5 cm x 30 cm. Contoh ttji diawetkan dengan larutan CCB konsentrasi 3% melalui proses selpenuh dengan tekanan 10 atmospher selama 2 jam. Contoh yang diawetkan dan yang tidak diawetkan ditlji terhadap penggerek kayu di laut selama 3 dan 6 bulan. Hasil penelitian menunjukkan bahwa contoh ttji yang tidak diawetkan mendapat serangan penggerek di laut. Sebaliknya, yang diawetkan dengan CCB sangat taban, terutama contoh ttji yang diambil dari pohon yang berumur 12 tahun. Penggerek yang menyerang adalah Martesia striata Linne. Dari Jamili Pboladidae, Teredo bartchi Clapp., Dicyathifer manni Wright., dan Bankia cieba Clench./Turner. Dari Jamili Teredinidae. Pada contoh ttji juga ditemukan crustacea yaitu Sphaeroma sp. Dari Jamili Sphaeromatidae.

Abstract

A detailed description of wood anatomy is essential for assessing the use of a wood species for processing , and also beneficial for the identification of wood samples. Computerized keys are available that allow the identification of wood samples until the genus level; however, it is not easy to use these keys to identif y unknown species. Therefore, a database of anatomical characteristics and the computerized keys need to be completed up to species level. As the relevance, this study has examined the wood anatomical properties of the five corresponding tree species originated from Cianjur, West Java, which are commercially potential for their exploitation, i.e Castanopsis acuminatissima ADC. (Fagaceae); Castanopsistungurrut ADC. (Fagaceae); Cinnamomum inners Reinw. ex Blume (Lauraceae); Ficus nervosa Heyne (Moraceae) and Horsfieldia glabra Warb. (Myristicaceae). Expectedly the results would be beneficial for wood identification purposes and evaluation for other possible uses. Obser vations on anatomical structures covered macroscopic and microscopic characteristics were carried out through the sectioned and macerated wood samples. The obser ved characteristics of the anatomical features were defined conforming to the IAWA List of Microscopic Features for Hardwood  Identification.  Based on the scrutiny on those obser ved characteristics and linked to the fiber quality, it was judged that the fiber in all the five wood species could be classified as class I for pulp and paper processing.

Abstract

Fast growing wood species could be promising to fulfill the gap between wood demand and supply. Due to their low quality, the utilization of fast growing wood species has been limited to pulp and paper. Our previous study on the fiber characteristic and density of the 30 unutilized fast growing wood species from PT Sari Bumi Kusuma, Central Kalimantan, showed that there were five species which could be promising as pulp and paper material. These wood species have fiber lengths of more than 2200 µm. This research was conducted to get information another property of the five woods to more discover their potential utilization, especially for pulp and paper material. The wood species investigated were Endospermum diadenum, Dillenia sp., Adinandra dumosa, Adinandra sp., and Nauclea junghuhnii. The results showed that these five species have a long of fiber length, which are classified in Class I, low to medium density, fiber derived value which the total score felt in the class I. The chemical compositions showed that extractive, holocelullose, α-cellulose, and lignin contents were 1.74-4.12%, 62.73-73.83%, 37.24-46.97%, 29.68-38.92%, respectively. Based on fiber characteristic, density, and chemical properties, these five species could be used as an alternative raw material for pulp and paper industries.

Abstract

Jenis kayu yang berasal dari hutan alam saat ini semakin berkurang, sebagai gantinya untuk mernenuhi kebutuhan kayu masyarakat, sebagian kayu dipenuhi dari hutan tanaman. Masalahnya, kayu yang berasal dari hutan tanaman relatif mempunyai umur atau berdaur tebang lebih muda dari hutan alam sehingga kandungan kayu muda (juvenilewood)nya relatif tinggi. Dalam pengolahan kayu, adanya kayu muda dalam balok sering menimbulkan masalah diantaranya timbul cacat dalam proses pengeringan sehingga kualitas kayu menurun. Oleh karena itu dalam penelitian ini diteliti karakteristik kayu muda yang meliputi sifat anatomi, dan kualitas pengeringan. Kayu yangdigunakan adalah mangium yang berumur 22 tahun, Hasil penelitian menunjukkan bahwa persentase kandungan kayu muda pada mangium yang diduga melalui persamaan regresi sekitar 50% (R.2= 70%) dengan karakteristik serat yang pendek, cacat permukaan, pecah dalam (honrycomb) dan perubahan bentuk (collapse) setelah proses pengeringan. Disarankan dalam proses pengolahan clan penggunaannya dilakukan secara hati-hati terutama pada waktu pengeringan sebaiknya mengikuti prosedur teknik pengeringan temperatur bertahap (bagan lunak).

Abstract

Tujuan penelitian ini adalah mengetahui pengaruh sifat fisik dan anatorni terhadap sifat pengeringan enam jenis kayu, yaitu tisuk (Hibisms 111acropf?yllus), gading (Koilodepas sp), mahang (Macarangaf?ypoleuca), telisai (Planchoniagrandis), sibau (Bl11meodendronkurzi1), clankenari (Santiria laevigata). Sifat fisik meliputi berat jenis dan penyusutan; sedangkan sifat anatomi kayu adalah lebar jari-jari. Sedangkan sifat pengeringan yang diuji meliputi cacat pecah ujung dan permukaan serta pecah di bagian dalam kayu, menggunakan metode pengeringan suhu tinggi (100°C). Berdasarkan kelas kerusakan/cacat yang terjadi dari hasil pengeringan suhu tinggi, kemudian ditetapkan sifat pengeringan untuk masing-masing jenis kayu. Hasil penelitian menunjukkan bahwa terdapat hubungan regresi geometrik antara BJ dengan penyusutan tangensial (R = 0,78), dan regresi linier antara lebar jari-jari dengan sifat pengeringan kayu (R = 0,60). Kayu tisuk dan sibau termasuk kayu yang sangat mudah dikeringkan karena memiliki berat jenis rendah sampai sedang, dan diameter pembuluh yang cukup besar. Kayu mahang, gading dan telisai sangat sulit dikeringkan. Faktor penyebab, di antaranya adalah berat jenis kayu yang terlalu tinggi (gading dan telisai) dan terlalu rendah (mahang), serta struktur anatomi yang tidak mendukung yaitu dinding serat yang tebal (kayu gading), diameter pembuluh kecil (mahang dan gading), dan berisi tilosis (gading dan telisai).

Abstract

This study was conducted to provide basis information of the 25 local specific wood species indigenous from Java treated by copper bichromated boron (CCB). The full-cell process for 2 hours and 150 psi during the pressure-keeping period was employed. The IUFRO method was applied for the determination of wood treatability class. The treated and untreated wood specimens were tied together using plastic cord, arranged into a raft like assembly, and then exposed for 3, 6, and 12 months to the brackish water situated at Rambut Island’s coastal area. The Nordic Wood Preservation Council (NWPC) standard No.1.4.2.2/75 was used to determine the intensity of marine borer infestation. The results revealed that 19 out of those 25 species were classified as easy to be preser ved, four species as moderate, and the remaining two were difficult to be preser ved. Those 19 species, i.e. Tamarindus indica L., Diplodiscus sp., Ficus variegate R .Br., Ehretia acuminata R .Br., Meliocope lunu-ankenda (Gaertn) T.G. Hartley, Colona javanica B.L., Pouteria duclitanBachni., Stercularia oblongata R .Br., Ficus vasculosa Wall ex Miq., Callophyllum grandiflorum JJS., Turpinia sphaerocarpa Hassk., Neolitsea triplinervia Merr., Acer niveum Bl., Sloanea sigun Szysz., Castanopsis acuminatissima A.DC., Cinnamomum iners Reinw. Ex Blume., Litsea angulata Bl., Ficus nervosa Heyne., and Horsfieldia glabra Warb. were more permeable implying that the CCB retention and penetration were greater and deeper. Hymeneaecarboril.L., LitseaodoriferaVal., Gironniera subasqualisPlanch., and LinderapolyanthaBoerl. were moderately permeable. Castanopsis tunggurut A.DC. and Azadirachta indica Juss. were the least permeable judging that the CCB retention and penetration were lowest and shallowest. The treated wood specimens in this regard were able to prevent marine borers attack. Meanwhile, the untreated specimens were susceptible to marine borers attack, except Azadirachta indica. The attacking borers consecutively are MartesiastriataLinne that belongs to the Pholadidae family ; and Teredo bartschi Clapp., Dicyathifer manni Wright., and Bankia cieba Clench. to the Terdinidae family.

Abstract

Recent studies of fast growing species grown in PT. Sari Bumi Kusuma, Central Kalimantan, show that based on their fiber dimensions there are five species, namely Endospermum diadenum, Dillenia spp., Adinandra dumosa, Adiandra sp., and Nauclea junghuhnii with good potential for pulp and paper production. The fiber length of those five wood species are was more than 2,200 µm on average. This paper studies the physical properties, fiber dimensions and their chemical contents to predict the paper and pulp quality. The result shows that all of the species were classified in the medium to high density category. All species were classified into the first class quality for pulp and paper. Based on chemical contents, Dillenia sp. is the most suitable species due to its high value of holocellulose and a-cellulose, low lignin content, and its fiber length is about 3,119 µm on average. A. dumosa also has good opportunities because it had the longest fiber lengths (3,137 µm on average) and high value of holocellulose, even though it has the highest lignin content. While Nuclea junghuhnii is less suitable due to low values of holocellulose and a-cellulose.
