Abstract

The utiliization of wood for cooling tower in Indonesia tends to increase and has become more important. Wood as material for cooling tower has been applied commercially in several developed countries such as New Zealand,USA and Japan. While in indonesia it has just been started in 1981 after the establishment of Kamojang Geothermal Power Station Unit 1. This paper deals with some experience in treating keruing wood (Dipterocarpus spp.) as material for cooling tower by vacuum-pressure impregnation. The result shows that keruing is easy to treat. In other to meet the retention of 24 kg/m3, the concentration of the solution must be at least 6.25 percent and absortion of 384 liters of preservative per cu.m.

Abstract

Penggunaan bahan finishing kayu dewasa ini dikuasai oleh bahan finishing dengan pelarut mineral, seperti melamin dan nitroselulosa. Meskipun bahan finishing ini dapat memberikan kualitas finishing yang baik, awet serta harga yang terjangkau, namun kelompok bahan finishing ini melepas banyak polutan, sehingga dapat merusak lingkungan dan berbahaya bagi kesehatan. Dalam penelitian ini dilakukan eksplorasi penggunaan bahan alternatif berupa ekstrak kayu jati yang dicampur dengan sirlak untuk produksi pewarnaan kayu atau lapisan atas. Performa bahan finishing alternatif diuji secara fisis, mekanis dan kimia pada kayu tusam dan karet, serta dibandingkan dengan performa bahan finishing komersial, yaitu melamin formaldehida (MF) dan nitroselulosa (NS). Contoh uji kedua jenis kayu direndam dalam larutan bahan finishing kemudian dikeringkan. Perubahan berat dan dimensi contoh uji akibat rendaman ditentukan pada kondisi basah dan kering. Hasil penelitian menunjukkan bahwa pertambahan berat dan perubahan dimensi akibat rendaman beragam menurut jenis kayu, orientasi serat dan jenis bahan finishing yang digunakan. Contoh kayu tusam mengalami perubahan berat dan dimensi lebih besar daripada kayu karet. Semua formula finishing organik mampu melindungi kayu dari intrusi air, namun tidak sebaik kelompok komersial MF dan NS. Formula lapisan atas ekstrak jati dan sirlak memiliki daya tahan terhadap larutan kimia dan ketahanan gores lebih rendah daripada MF dan NS. Namun demikian, formula pewarnaan kayu ekstrak jati dan sirlak memiliki nilai warna lebih baik daripada wood stain komersil.

Abstract

Analysis on the integrated production of charcoal and  wood vinegarhas  been conducted using the raw materials  of three wood species, i.e. mangrove (Bruguera sp.), mangium (Acacia mangium), and tusam (Pinus merkusii). As such, those three were each carbonized into charcoal through a direct burning  in a dome kiln with 2 m3 capacity;  and concurrently,  the distillation  through  the cooling of.the generated  gas/vapor fraction  was conducted to collect the wood vinegar. The resulting charcoal werefurther treated  either with or without purification process. To evaluate the qualities of the two products (i.e. charcoal and wood vinegar), the physico-chemical  and economic analyses were examined. Economic analysis covered the collection of data/information on purchasing prices of the equipment.  material-procuring cost for  the kiln, kiln-erection cost. production cost, cost of procuring auxiliary matters,  charcoal and wood vinegar prices,  and others, followed by their assessment. Results of the analysis  were as follows:Integrated production  of charcoal and the one of wood vinegar turned out to be the best with respect to their  technical  aspects and physico-chemical properties was from  the raw material of mangrove  wood species.  In this regard, the yield of charcoal and wood vinegar was the highest. Likewise, the qualities  of the charcoal could correspond to usage standard  of charcoal for iron ore. Also, the qualities of the wood vinegar could meet the Japan Standard Requirement.The implementation of purification treatment on the resulting charcoal could decrease the volatile matter content, and increase fixed carbon content and  calorific  value  without   affecting  the production of  wood  vinegar. As  such,   the  volatile  matter  contents  in mangium charcoal decreased from 27.09 percent  to  17.35   percent,  and  in tusam charcoal from 33.18  percent to 24. 79 percent.Productions of charcoal and wood vinegar for one m3  of wood were in the range of 181- 217 kg and 169 -  205 kg, respectively for mangrove wood;  110  -121 kg and 121 -  125  kg, respectively formangium wood; and 111-121 kg and 141  kg, respectively for tusam wood.Production of charcoal which is in  integration  with the one of wood vinegar can gain  a significant benefit. Such benefit can be achieved after 5 years of wood vinegar production, i.e.  82.6 percent per year from  mangrove wood, and  mangium as well as tusam wood.   Conversely, the production of  wood vinegar in integration with the one of charcoal can gain additional benefit, i.e. 39.7 percent per year from mangrove wood, and 39.9 percent per-year from mangium as well-as-tusam wood. The benefit per year of such integrated  production in the sixth year will be even greater, since the interest payment and loan can be ultimately fulfilled. All  the investment of the factory with implements an integrated production-of  charcoal and wood vinegar can be returned in one year and 3 months.

Abstract

One way to overcome the shortages of raw material for wood based industries in Indonesia nowadays is to utilize the lesser known wood species. Therefore, the basic properties of these lesser known wood species should be studied. Wood anatomy of nine lesser known wood species from East Kalimantan have been observed and described for identification purposes and for evaluation of their properties and then appropriate uses.For identification purpose several main features have been noted : 1) Perforation plat scalariform in Mastixia trichotoma and Drypetes sp.; 2) Closely spaced parenchyma bands and radial intercellular canal in Ficus variegata; 3) Parenchyma reticulate in Drypetes sp, Diospyro macrophylla and Koilodepas sp.; 4) Fiber septate in Glochidion philippicum; 5) Rays almos exlusively homocelullar with gum-like deposite in vessels o/Lansium sp.Seven out of nine wood species examined containfibers of medium quality for pulp and paper among others : Blumeodendron kurzii, Ficus variegata and Mastixia trichtoma. The other two species contain fibers with poor quality. Two species, Drypetes sp. and Koilodepas sp. have light colour and decorative appearance and with considerable strength to be used as raw material for fancy furniture and decorative panel. Ficus variegata has anatomical structure which allow it too easily be peeled in to fine decorative veneer for plywood.Key words : Lesser known wood species, wood anatomy, identification, fiber quality.
