The problem in using plywood bonded with urea formaldehyde (UF) is formaldehyde emission, especially in a room with limited ventilation. To reduce formaldehyde emission, the glue can be mixed with catching agent. In this paper the effect of urea and melamine as catching agent on formaldehyde emission and on bonding strength of UF bonded plywood made from red meranti (shorea. spp) is discussed.The effect of catching agent type on formaldehyde emission is not significant while the effect of percentage of catching agent is highly significant on formaldehyde emission. The higher percentage of catching agent, the lower formaldehyde emission of plywood.The effect of catching agent type on plywood bonding strength is not significant, but the effect of percentage of catching agent is highly significant. The higher percentage of urea the lower plywood bonding strength, while the higher percentage of melamine and urea-melamine cause the higher plywood bonding strength. To meet formaldehyde emission of 0.165 ug/ml, it is recomended to use 10% urea on the weight basis of liquid UF.

Sumatera Utara merupakan sentra produksi kemenyan di Indonesia. Kemenyan di pasaran dikelompokkan menjadi 6 kualitas berdasarkan kriteria uji ukuran (besar kecilnya) lempengan/ bongkahan dan warna kemenyan, yaitu kualitas I s/d VI.Tujuan penelitian ini dimaksudkan untuk mengetahui perbedaan sifat fisiko-kimia kemenyan berbagai kualitas yang ada di pasaran, sehingga diharapkan nantinya pengelompokkan kualitas kemenyan dapat dipertimbangkan secara kuantitatif berdasarkan unsur-unsur sifat fisiko-kimianya. Sifat fisiko-kimia kemenyan yang diuji adalah warna, bentuk, ukuran, kadar air, kadar kotoran, kadar abu, titik lunak dan kadar asam balsamat.Hasil analisa menunjukkan bahwa kadar air dan kadar abu relatif sama antara kemenyan kualitas I, II, III, IV dan V. Kadar kotoran dan titik lunak kemenyan kualitas I, II, III dan IV adalah relatif sama, sedangkan kadar asam balsamat kemenyan kualitas I, II dan III relatif sama. Dengan demikian disarankan pembagian kualitas kemenyan menjadi 4 kelas kualitas yaitu kualitas I berasal dari kemenyan kualitas I s/d III, kualitas II berasal dari kemenyan kualitas IV, kualitas III berasal dari kemenyan kualitas V dan kualitas IV berasal dari kemenyan kualitas VI.

Meningkatnya konsumsi bahan bakar fosil sedangkan cadangannya semakin menurun menyebabkan terjadinya krisis energi. Hal ini memicu penggalian energi alternatif sebagai pengganti energi fosil tersebut. Bioetanol merupakan salah satu energi alternatif yang berasal dari bahan nabati. Penelitian ini bertujuan membuat mesin alat/ pengolah bioetanol dari bahan nira nipah. Alat rekayasa yang dibuat terdiri dari 2 buah reaktor. Reaktor I berfungsi sebagai alat pasteurisasi, sakarifikasi dan fermentasi. Reaktor II berfungsi sebagai alat destilasi. Keunggulan alat ini terdapat pada penggunaan teknik Simultaneous Sacarification and Fermentation (SSF) dimana proses pasteurisasi dan fermentasi dapat dilakukan pada 1 reaktor. Laju alir uap bioetanol masih berlangsung lambat menjadi kelemahan alat ini. Rendemen nira nipah hasil ujicoba sebesar 13,5% dan kadar bioetanol berkisar antara 70-94,5% dengan rata-rata sebesar 84,8%. Hasil destilasi bioetanol dapat ditingkatkan melalui proses dehidrasi. Melalui proses dehidrasi kadar bioetanol 94,5% dapat meningkat menjadi 98,5%.

An investigation of skidding performance was conducted at one Forest company in Riau, in 1988. The results showed that stand density rangea from 126 to 190 trees with an average of 158 trees/ha, soft soil .without any rock, land slope ranges from 6,8 to 20,0 % and the trees felled from 2 to 8 with an average of 5 trees/ha. Also it was found that the length of productive skidding road ranges from 91,0 m to 329,8 m with an average of 210,4 m /ha while the length of unprodue- tive skidding road vanes from 2,5 m to 49,9 m with an average of 26,2 m/ha. The ratio between the lengths of unproductive and productive skidding road is 12,5 %. By considering tractor's life time 20.000 hours, around 2.500 hours of them are unproductiue, Relating this figure with owning and operating costs, those unproductive skidding road surely cause quite large loss. Besides, the unproductive tractor movements also cause land exposure to the amount of 122,5 m2/ha. All the above disadvantages can be minimized by planning akidding roads ahead and strictly controlling the operation.

An investigation on construction cost and wood use in railroad tracks in swamp forests has been carried out at two companies located in West Kalimantan in 1983.The investigation arrives at the following conclusion:The construction of both wooden and steel railroad tracks uses 4 layers of sleepers. The difference between the two lies in the rails itself.The bearing capacity of steel railroad track ranges from 2 to 4 tons, while that of wooden railroad track from 10 to 15 tons.Construction cost of wooden railroad tracks is lower than that of steel railroad tracks, i.e., Rp. 2.350.000.-/km and Rp. 11.483.000.-/km respectively. The volume of wood used in wooden and steel railroad tracks is 243 m3/km and 241 m3/km respectively.The amounts of wood used between wooden railroad tracks and steel railroad tracks do not differ significantly. Among layer, however, they differ highly significantly.

Keruing oils can be obtained through separating the oil from keruing gum by distillation technique, or distilling keruing wood. In accordance with the lattest method, the objective of this research is to study the physico-chemical properties of keruing oils which were obtained by steam distillation of a mixture of several keruing wood species. This wood was randomly taken three times from the wastes of wood processing industry in East Kalimantan. Each wood wastes taken was steam distilled and the yielded oils were analysed their physico-chemical properties. The difference between means value of the properties of the oils was tested by using LSD according td SAS procedure.Results revealed that wood wastes gave a highly significant effect on refractive index, optical rotation, acid and ester number of keruing oils. It also gave a significant effect on saponification number. Further analysis showed that the keruing oil with clear colour compared to both keruing oil with clear yellow and pale yellow colour was a significant difference in acid and ester number. Moreover, the keruing oil with pale yellow colour had ll significant difference in saponification number compared the others. Among these oils, the refractive index and optical rotation properties were a significant difference one to the others. Based these results, if the keruing wood wastes will be used as raw materials for keruing oil production, it is better that the keruing wood containing much oil or gum should be separated from the others before further processing.Keywords: Keruing oil, Dipterocarpus spp, Steam distillation, oil properties

Sastrodimedjo, (1975) pointed out that the present trend of wood processing industry development and formal education of younger generation caused some problems, especially in the sustainabiliy of forest worker supply in Java.Based on this consideration an alternatif for most widely applied felling system, i.e. manual felling system, needs to be sought. With regard to this problem a study was conducted at three Sub Forest District (RPH), namely Temenggeng, Pasar Sore and Sumberogo in Central Java to compare 3 (three) felling systems in teak forest.The result of the study revealed that the teak felling productivity averages on 2 years gilrded teak with mechanical, manual and combination systems applied to flat terrain were 2.5359 m3/hour, 0.7128 m3/hour and 0.8186 m3/hour, respectively. But those on hilly terrain were 1.5540 m3/hour, 0.7374 m3/hour and 0.796 m3/hour, respectively. The average cost of full mechanical felling system applied to flat terrain was Rp 1,586.23/m3, while that of on hilly terrain was Rp 2,l 65.93/m3

Nipah (Nypa fruticans Wurmb.) menghasilkan nira yang dapat diperoleh melalui penyadapan tandan buah. Dalam keadaan segar nira nipah memiliki rasa manis karena mengandung gula yang cukup tinggi. Cairan ini merupakan media yang subur bagi pertumbuhan mikroorganisme, sehingga nira nipah berpotensi digunakan sebagai bahan baku untuk menghasilkan produk melalui proses fermentasi seperti nata. Nata merupakan jenis pangan yang dikelompokkan sebagai makanan penyegar atau pencuci mulut. Percobaan produksi nata fruticans dilakukan melalui proses fermentasi nira nipah yang masih segar dengan perlakuan penambahan gula 0, 50, 75 dan 100 g per liter nira nipah. Produksi nata fruticans dari nira nipah segar yang ditambahkan gula pada berbagai kadar diperoleh rendemen antara 76,52%-90,97% atau rata-rata 86,05%. Penambahan gula pada nira nipah segar berpengaruh tidak nyata terhadap rendemen produksi nata fruticans. Penggunaan nira nipah segar dengantanpa penambahan gula menghasilkan nata fruticans dengan rendemen rata-rata 83,74%.

Wood materials from plantation timber, among others is mangium (Acacia mangium Willd.) are supposed to be more susceptible to the wood-degrading organisms. This situation can expectedly be overcome by improving wood durability through a proper preservation. Previous study of the preservation of mangium wood was only by cold soaking treatment, using boron preservative. In order to provide a complete practical guidance of wood preservation, it would be necessary to study the preservation of such mangium by hot-cold treatment with not only boron but also CCB (copper-chrome-boron) preservatives.Mangium wood samples, after reaching their air-dry condition in block-shaped size measuring 5cm by 5cm by 100cm were treated by hot-cold soaking separately in solution of boron and CCB preservatives, varying at consecutively 5 percent, 7,5 percent and 10 percent. The treatment in this regard was implementing a particular schedule, which involved the regulation of soaking durations and temperatures. The durations in the hot-soaking stage for each preservative strength were 1 hour, 2 hours and 3 hours, with the temperature maintained at 65 to 70 °C. In the following cold-soaking stage, the durations were fixed for one day.The results showed that mangium wood treated with hot-cold soaking in either boron or CCB solution and implementing such particular schedule was only applicable for indoor uses, i.e. being under the roof utilization without ground contact. In this matter, the optimum strength for boron as well as CCB preservatives was 10 percent whereby the durations of hot-soaking stage were from one and three hours, followed by cold-soaking stage for one day.
