Keawetan merupakan salah satu aspek penting dalam penelitian sifat dasar bambu. Sebagai bahanberlignoselulosa alami, bambu mudah diserang organisme perusak termasuk jamur. Pengujianketahanan bambu terhadap organisme perusak pada umumnya mengikuti metode laboratorium yangtelah diterapkan pada kayu, seperti penggunaan bacto agar. Pengujian dengan hamparan tanahmerupakan salah satu alternatif untuk menguji ketahanan bambu terhadap jamur, karena metode inimurah dan mudah dilakukan. Tulisan ini mempelajari cara pengujian keawetan bilah bambu denganmetode hamparan tanah. Contoh uji bilah bambu diambil dari bagian dalam (i), tengah (m) dan luar (o)dan bagian pangkal (B) , tengah (M) dan ujung (T). Hasilnya menunjukkan bilah bambu dari bagiandalam (i) lebihmudah diserang jamur dari bagian tengah (m) dan luar (o). Setelah enam bulan, contoh ujidari bagian dalam gagal dalam uji tusuk dan uji patah dengan tangan, sedangkan bilah dari bagian tengahgagal setelah delapan bulan pengujian. Contoh uji yang diuji dengan kemampuan tanah menahan air100% lebihmudah terserang jamur daripada contoh uji yang ditanam pada tanah yang mampu menahanair 80%. Bilah bambu dari bagian bawah (B) lebih tahan terhadap serangan jamur dari bagian tengah (M)dan atas (T), namun perbedaannya kurang nyata. Pada umumnya pengujian bilah bambu denganhamparan tanah dapat dijadikan metode pengujian alternatif untuk menentukan keawetan bilah bambuterhadap jamur.

Fungi resistance of 5, 8 and 11 year old sap and heart Acacia mangium Willd wood, taken from Parungpanjang (West Java Province) and Serang (Banten Province) were evaluated using modified DIN 52176 standard. The result showed that wood samples from Parungpanjang was classified as moderately resistant to resistant (class III-II), while those from Serang district as non resistant (class IV). Both the sap and heart wood had similar resistance (i.e. class III). The percentage of the weight loss of the heart wood was lower than that of the sap wood. The lowest weight loss was found on 11 year old samples, taken from Parungpanjang district. The highest weight loss was found on 8 year old samples from the same area and on 11 year old samples from Serang. The most virulent fungus was Coriolus versicolor followed by Tyromyces palustris, Polyporus sp. HHB-209, Pycnoporus sanguineus HHB-324, Schizophyllum commune HHB-204, Postia placenta. The less virulent ones were Dacryopinax spathularia, Chaetomium globosum, Pycnoporus sanguineus HHB-8149, and Phlebia brevispora The highest weight loss was recorded on the sap wood of 8 year old samples from Parungpanjang exposed to Lentinus lepideus culture, the lowest was on the heart wood (from the trees of the same age and origin) exposed to D. spathularia culture. The resistance of wood could be affected by the tree-growth site, age, position in the log, species and strain of fungi

Produk komposit dari rotan memiliki nilai dekoratif dan berpotensi untuk dikembangkan terhadap minat pasar saat ini. Papan rotan lamina diharapkan dapat digunakan sebagai bahan substitusi mebel kayu. Penelitian ini bertujuan untuk mempelajari pembuatan papan rotan lamina dari jenis rotan besar berdiameter lebih dari 30 mm dengan perekat berbasis fenol dari kulit kayu mangium, kulit kayu mahoni, dan serbuk kayu gergajian merbau. Papan lamina rotan berukuran 1,5 cm x 7,5 cm x 90 cm terbuat dari lima lapis yang dilabur pada salah satu sisi permukaan dan dikempa panas dengan tekanan spesifik 10 kg/cm2 selama tiga jam. Pengujian produk papan lamina rotan meliputi keteguhan rekat dan emisi formaldehida, serta nilai keteguhan rekat contoh uji dari Pusat Inovasi Rotan Nasional (PIRNas) sebagai pembanding. Hasil penelitian menunjukkan bahwa keteguhan rekat dan emisi formadehida papan lamina rotan dipengaruhi oleh interaksi jenis bahan baku tanin, suhu kempa dan bobot labur. Kualitas rekat papan rotan terbaik diperoleh pada penggunaan perekat tanin formaldehida mangium berbobot labur 200 g/m2 permukaan dan suhu kempa 100oC, dengan emisi formaldehida yang masih dalam batas aman. Lebih lanjut, dari sekitar 28% papan lamina rotan hasil percobaan, nilai keteguhan rekatnya melebihi nilai keteguhan rekat papan PIRNas yang menggunakan perekat sintetis impor berbasis fenolik.

The objective of this research is to study the effect of treatments on seed and pressing temperatures on candle nut oil properties. The treatments consisted of steaming, dry-frying and control. The candle nut seed having been treated was pressed at temperatures of 65and 135°c. The data obtained were analysed by using fac.torial design and the difference between means were tested with the LSD procedure, calculated with SAS program.Vie results showed that an increase in a pressing temperature caused a decrease in a peroxide number and an increase in an iod number. The dry frying treatment on seed before pressing activities produced a few deterioration on candle nut oil, denoted by a high value of iod number and a small value of peroxide and saponification numbers. Compared to a steaming treatment or a control, the dry frying treatment gave a better quality on candle nut oil indicated by a higher value of iod number. .

ANATOMICAL PROPERTIES OF FIVE MAJOR WOOD SPECIES CROWN IN JAMBI, SUMATERA Y I Mandang; Krisdianto Krisdianto

Publisher : Pusat Penelitian dan Pengembangan Hasil Hutan

General characteristics and anatomical properties of several major wood species in Jambi, Sumatera, have been studied. The purpose is to find out their characters for identification, their appropriate uses and their possibilities to be widely cultivated. Five major wood species have been identified and described: balam (Palaquium gutta Bail.), bayur (Pterospermum diversifolium BI.), medang (Litsea sp.), mahang (Macaranga pruinosa Muell.Arg.) and merkubung (Mac.-ranga gigantea Muell.Arg.). Balam and bayur are suitable for house construction, plywood, furniture: and their fibres are fairly good for pulp. Therefore balam and bayur are highly recommended to be widely cultivated. Mahang and merkubung are too light and soft for construction purposes where strength properties are of prime importance. However mahang and merkubung fibres are of good quality so they still can be recommended to be widely cultivated for pulp source. Medang is fairly appropriate for construction purposes and having fairly good quality fibres as well. However the occurrence of oil cells inside wood tissue and the possible effect of the exudate on gluability and paintability, have to be considered before decision is made for its cultivation in large quantities.

Publisher : Pusat Penelitian dan Pengembangan Hasil Hutan

Empat puluh lima jenis kayu yang berasal dari beberapa daerah di Indonesia diuji sifat ketahanan alaminya terhadap rayap kayu kering (Cryptotermes cynocephalus Light.) dan rayap tanah (Coptotermes curvignathus Holmgreen). Pengujian ketahanan terhadap rayap tanah dan rayap kayu kering dilakukan sesuai dengan metode SNI 7207:2014. Hasil penelitian menunjukkan bahwa dari 45 jenis kayu yang dipelajari, enam jenis dari 45 jenis kayu yang diteliti tergolong sangat tahan (kelas awet I), 11 jenis tahan (kelas awet II) dan sisanya 28 jenis masuk ke dalam kelas awet rendah (III, IV dan V) terhadap C. cynocephalus Light. Hasil pengujian ketahanan terhadap C. curvignathus Holmgreen menunjukkan tujuh jenis tergolong sangat tahan (kelas awet I), 14 jenis tahan (kelas awet II), dan sisanya 24 jenis masuk ke dalam kelas awet rendah (III, IV dan V). Hasil penelitian juga menunjukkan bahwa jenis kayu yang tahan terhadap rayap kayu kering belum tentu tahan terhadap rayap tanah, dan sebaliknya.

The effects of bleaching of sega rattan (Calamus caesius Bl) peel by soaking in the hydrogen peroxyde of several concentration levels (1 , 3, 5, and 7 percent) and soaking times ( 1, 3, and 5 hours) on rattan peel quality were studied at the Forest Products Research and Development Centre Laboratory in Bogor. Results showed that the unblea- ched rattan peel has the brightness of 38.8 percent and the tensile strength parallel to grain of 412.09 kg/cm2 while for the bleached ones, those figures are 44. 74 percent and 374.99 kg/cm2, respectively.It is found that bleaching agent concenlration has a highly significant effect on both brightness and tensile strength parallel to grain. The brightness (Y) was significantly improved with the increasing of bleaching agent concentrations (X) which can be expressed by the regression equation of Y = 40.2365 + 1.1265 X (r = 0.9992). On the other hand, tensile strength (Y) was significantly decreased with the increasing of hydrogen peroxyde concentrations (X, as expressed by the following rearession equation: Y = 421.37 5 - 11.675 x (r = 0.9888 ).The apllcation of 5 percent hydrogen peroxyde concentration is optimum which could improve the brightness up to 46. 03 percent, and reduced the tensile strength down to 364.8 kg/cm2.
