Kayu merupakan bahan lignoselulosa yang mudah terserang organisme perusak sehingga perlu diawetkan untuk meningkatkan umur pakainya. Tingkat perlindungan kayu dipengaruhi oleh keberhasilan masuknya bahan pengawet ke dalam kayu. Retensi dan penetrasi bahan pengawet ke dalam kayu adalah dua parameter yang ditetapkan untuk mengukur keberhasilan masuknya bahan pengawet ke dalam kayu (keterawetan). Retensi bahan pengawet dihitung berdasarkan sistem gravimetrik perbedaan berat, sedangkan penetrasi diukur berdasarkan perbedaan warna akibat uji semprot (spot test). Saat ini, penetrasi bahan pengawet dinilai secara visual dan persentasinya dalam bidang luasan dihitung secara konvensional. Interpretasi penetrasi bahan pengawet dapat dilakukan berdasarkan foto digital menggunakan perangkat lunak Image-J. Tulisan ini mempelajari keterawetan enam jenis kayu dari Jawa Barat dan Riau. Perbandingan pengukuran penetrasi dilakukan dengan cara konvensional dan interpretasi foto digital. Hasil penelitian menunjukkan bahwa kayu hamirung, jaha dan mahang putih termasuk mudah diawetkan (kelas I), sedangkan kayu bung bulang, pasang taritih dan bira-bira termasuk kelas keterawetan sedang (kelas II). Penilaian penetrasi dengan interpretasi digital lebih akurat, cepat, dan mudah daripada dengan cara konvensional.

Variables used in this investigation are wood species (Jelutung and keruing), carbonization temperatures (400°C and 500°C) and activators (CaCl2, MgCl2 and ZnCl2). The parameters observed were yield, moisture content, ash content, iodine and benzene adsorption. This investigation reveals that the highest yield obtained from keruing wood, CpCl2 activator at carbonization temperature of 400°C. The lowest moisture content charcoal obtained by using processing temperature of 500°C. Jelutung wood with MgCl2 activator had the lowest moisture content compared to that of ZnCl2 activator. The highest iodine adsorption obtained when using ZnCl2 activator and carbonization temperature of 500°C (for keruing wood). It was found that high benzene vapor adsorption charcoal could be produced by using ZnCl2 activator, carbonization temperature 500°C and Jelutung wood as raw material.Sunbury, H.M. (1923).

Rapid destructive of Jackfruit wood was carried out by using a retort equipped with electrical heating system. This retort was also connected to a condensor and two flask to catch and collect the distillate or condensed gas. The retort capacity was about 4 kg of wood. Treatment conditions given in these experiment were maximum heating temperature of 500◦ C and 5 hours distillation time.The results showed that charcoal yield of Jackfruit wood varied from 25.00 to 39.81%, tar from 6.23 to 9.42% and pyroligneous liquor from 67.64 to 102.05%. The calorific value of wood varied from 4392.00 to 4620.65 kcal/g and charcoal from 6691.81 to 7108.37 kcal/g.Based on these calorific values, wood and charcoal of Jackfruit wood are excellent material for fuel.

An experiment of glued lamination has been conducted and their mechanical properties were tested. The pile component of glued laminated wood samples were prepared consisting of two jointed wood species with 2 (two), 3 (three) and 4 (four) layers. The dimension of glued laminated samples is 5 cm x 5 cm x 76 cm and all components were connected by glue. The mechanical properties observed are modulus of elasticity (MOE), modulus of rupture (MOR), compreesion parallel to the grain, shear parallel- to the grain (radial* and tangential) by Balwin universal testing machine with ASTM method.The results show that the mechanical properties glued laminated samples are adequate for construction purpose.

A study for production of glucose and alcohol from sago (Metroxylon Spp) was conducted on a laboratory scale in the Forest Product Research and Development Centre, Bogor.Treatment condition given for hydrolysis of sago in order to produce glucose was three levels of sulfuric acid (of 0.5 N; 0,75 N and 1.0 N) with three levels of temperature and pressure (of 250°F/15psi, 259°F/20psi, and 274oF/30psi).The reaction time for hydrolysis at each treatment combination were three levels (of 90 minutes, 120 minutes and 150 minutes). Glucose obtained from sago hydrolysis in this experiment was then fermented for producing alcohol by means of Sacharomyses cereuiciae enzym activity from yeast.The result showed that glucose yield during these experiment ranged from 42.8 to 77,6 percent. The maximum glucose yield is obtained from the 274°F/30psi treating condition and sulfuric acid concentration of 1.0 N within 120 minutes of hydrolysis time. Until 120 minutes of hydrolysis period the glucose yield tend to increase with the increasing treatment combination level. The results of glucose tends to decrease afterwards at hydrolysis period of 1.50 minutes.The highest alcohol yield is 14.2 percent and is obtained from fermentation of highest glucose yield of 77.6 percent. Based on the result of chromatographic analysis of alcohol revealed that alcohol produced is classified cu. ethanol (C2H50H)

Proses asetilasi bertujuan mensubstitusi gugus hidroksil dalam kayu dengan gugus asetil. Denganmeningkatnya gugus asetil dalam kayu diharapkan mampu mengurangi kemampuan kayu menyerapmolekul air sehingga dimensi kayunya menjadi lebih stabil. Penelitian ini bertujuan mempelajaripenyerapan uap air pada kayu yang sudah diasetilasi. Studi dilakukan terhadap dua jenis kayu tropis yaitu:Anthocephalus chinensisdanCalophyllum sp. Pengujian penyerapan uap air dilakukan dengan metode isotherm menggunakan desikator dan larutan yang memiliki sifat higroskopis. Hasilnya menunjukkan bahwa kayu Anthocephalus yang diasetilasi secara efektif mampu mengurangi penyerapan uap air walaupun pada tingkat penambahan berat yang paling rendah. Pada kayuCalophyllum sp. penyerapan uap air berkurang secara nyata pada penambahan berat 10%. Penyerapan uap air bervariasi tergantung dari kelembaban kondisi pengujian dan membentuk model sigmoid dari kelembaban terendah (11%) sampai tertinggi (97%).

Keberadaan logam berat krom dari limbah industri elektroplating dapat membahayakan kesehatan manusia, di antaranya menyebabkan kanker dan gagal ginjal. Untuk mengatasi masalah ini, dilakukan upaya pengolahan limbah dengan cara adsorpsi menggunakan arang aktif dari kayu. Tulisan ini mempelajari kondisi optimal uji adsorpsi arang aktif kayu Muntingia calabura dan kemampuan bakteri Escherichia coli melakukan biodegradasi krom (VI) menjadi krom (III) pada pengolahan limbah krom industri elektroplating. Arang kayu dibuat pada suhu 500˚C selama 1 jam dan diaktivasi dengan uap air panas pada suhu 800˚C pada variasi waktu kontak 70-110 menit dengan tekanan 120 dan 150 mBar. Uji adsorpsi dilakukan dengan variasi konsentrasi awal adsorbat 20-100 mg/L, waktu kontak 45-105 menit, dan kecepatan pengadukan 100-300 rpm. Uji biodegradasi menggunakan bakteri Escherichia coli yang diinkubasi di dalam nutrient broth yang mengandung limbah hasil adsorpsi. Hasil penelitian memperlihatkan bahwa kondisi optimal uji adsorpsi adalah konsentrasi awal 70 mg/L, kecepatan pengadukan 150 rpm dan waktu kontak pada 75 menit, dengan efektivitas sebesar 86,7%. Efektifitas biodegradasi krom (VI) menjadi krom (III) adalah 98,6%.

The main source of revenue for forestry development up to now still depends on natural forest which is the main source of wood for the industries. In the utilization of natural forest the assessment of stumpage value is important to determine the profit margin that goes to goverment as well as to the concession holder.The objective of this study is to get clear picture on the cost components of forest concession and to know the stumpage value of forest land. To determine the stumpage value a production cost analysis was done based on a year operation of concession holder.The results showed that the cost components of log production consists of planning, building main road and skidding road, road maintenance and log houling with total production cost Rp. 58.480,- per m3 for felled area of 1000 ha with production of meranti and mixed species each 22.003,47 m3 and 7. 720, 78 m3, respectively. Based on profit ratio 35% which went to concession holder there is still surplus which the goverment presently does not collect as forest owner. Based on this result goverment revenue in the forms of forest product fee, reforestation fund and concession fee can be increased up to 200% from present level.Key Word : Natural Forest, Stumpage Value, Forest Concession, Production Cost, Forest Product Fee, Reforestation Fund, Concession Fee.
