The aim of this research is to improve charcoal kiln and production techniques so that yield and quality can be optimazed with less capital operating cost.The kiln used in this experiment was made from a typical 200 litre oil drum with special design incorporating 12 holes of 13 mm in diameter in different elevations, at the base, 30 cm and 60 cm above the base. A short chimney of 30 cm height at the top with 10 cm in was also installed diameter.This report discusses the experimental procedures including raw material preparation, loading and operation of tedrum kiln. The yield all qualities of the charcoal produced are also discussed in this report. The results of this experiment showed that single Drum Kiln can produce high charcoal yield ranging from 33,8 % to 37,2 % and average of 35,7 %.A comparison of results with survey data shows that the quality of the coconut shell charcoal produced by the drum kiln method. conform favorably with the quality of charcoal being used for production of commercial activated carbon.

Rapid destructive distillation of 20 Industrial Forest Plantation Timber Species was carried out by using a retort equipped with electrical heating system. This retort was also connected to three condensors 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 product (charcoal, tar, pyroligneous liquor) of the destructive distillation of wood showed a wide variation in yield or composition depending on the wood species, age and growth location.This experimental condition produces charcoal yield varying from 21,38 - 38,00%, tar from 4.99 - 13.78% and pyroligneous liquor from 44.91 - 157.17%. Pyroligneous liquor product can be used as disinfectant, weed killer and deodorant. Tar product has a good prospect for wood preservative subtance and medicinal.The destructive distillation of wood under these experimental conditions produced brittle and light charcoal. On the contrarary, hard charcoal could be produced from slower pyrolisis process in a commercial scale.Proximate analyses of charcoal obtained from these experiments revealed that the quality IS suitable for both as raw material for commercial activated carbon and fuel.Calorific values of wood ranged from 4285 to 4994 kcal/kg and charcoal from 6746 to 7748 kcal/kg. Based on these calorific values, wood and charcoal of the 20 wood species observed are excellent material to be used as fuel.

The Forest Product Research and Development Centre, Bogor, has constructed the Lorena, Singer and the Traditional fuelwood stoves to measured the efficiency of each type. The material used for the construction of the stoves are clay, sand, sawdust, red-bricks and water.The efficiency of each type is measured by using the stoves for cooking water to boiling point in an aluminium pan, where rubber (Hevea brasiliensis) wood is used as fuelwood.The stoves efficiency is expressed as the ratio between the effective heat the boiled water absorbs and the potensial heat produced by firewoods.The results of the observations and calculations of the efficiency of the respective types of firewood stoves indicated that the Lorena stove has the highest efficiency of 24.75%, followed by the Singer stove with 24.50%, and the traditional one, the least efficient is 18.64%. Compared with the tested traditional stove, the Lorena and the Singer stoves appear to have high efficiency which consumed 30% less of fuelwood.

ANALISIS KIMIA 6 JENIS KAYU UNTUK HUTAN TANAMAN INDUSTRI Gustan Pari; Nurmala Hudaya

This paper deals with a chemical analysis of six wood species obtained from industrial plantation Forest. The analysis comprises of the determination of holocellulose. lignin, pentosan, moisture content, ash content, silica content and solubility in cold water hot water, sodium hydroxide and ethanol benzene content. The result shows that holocellulose content ranges from 50.2 - 63.2 percent, cellulose from 42.6 - 56.2 percent. The high. celloluse content are Dipterocarpus haseltii, Diryobalanops lanceollata, Shorea and Agathis ]orantifo1ia. Lignin '(rom .24. 7 - 3'2.4 percent, pentosan from 15.2 - 19.0 percent. ash cotent from 0. 4 - 1. 8 percent. Silica content from 0.1 - a. 2 percent, moisture content from 10.2 - 32.0 percent. Solubility in cold water from 2. 0 - 5.1 percent, hot water from 3.5 - 5.8 percent, in one percent sodium hydroxide from 12.9 - 17. 6 percent and so lubility in ethano1-benzene (1:2) from 5.2 - 13.2 percent.Based on chemical analysis, especially the cellulose contants the ,six wood species for timber estate are suitable as raw material for pulp and paper industry.

Research on µtilization of several seed shells of Aleurites moluccana, Hevea brasiliensis, Canarium communne L and Cocos nucifera for activated carbon by means of steam or ZnCl2 solution activat.ionwas conducted at the Forest• Product• Beaearch and Development Centre, Bogor.The results1howed that all kinds of raw material used could produce good quality and high yield of activated carbon. The yield of activated carbon produced were re1pectively ranging 'from 81,1-87,0% (Qmarium communne L.),66,4-77,1% (Aleurites moluecana), 65,3-71,3% (Hevea brasiliensis), 65,7-77,3% {Cocosnucifera). The quality of activat- ed carbon determened by adBorptive capacity of Iodine number need the• requirement as specified Standard of A WWA (1978) i.e minimum 500 mg/g.
