Abstract

Tisuk (Hibiscus macrophyllus Roxb.) and sukun (Artocarpus  horridus Jarret.) trees are numerously planted by the rural community in Ciamis regency. The wood  portion of  tisuk  has been much in use for constructions material and furniture, while sukun is intended as multipurpose  plants. Due  to poor or low durability of  the wood portion in both species,  prior  to  its uses, it should be preserved or treated. Preservation  scheme for both wood species     with   particular preservatives, unfortunately, has not yet been available.  Therefore. a through   investigation is urgently required to work  out such a proper  scheme.Inherent  with  such, ninety  pieces or wood  samples, measuring of 5 by 5 by 30 cm, were  prepared from each  of both  species for the treating  trial. After being dried, the samples  pieces  were treated with CCB (copper-chrome-boron) and boron preservatives by the full-cell process. The preservatives (CCB and boron)  were each  used  in solution at  three varying  concentrations, i.e. 2, 3, and  4 percent. Initial and  final vacuums were  maintained at 600  mmHg  for 30  and 15  minutes respectively. On  the other  hand, the treating phase was employed at  three  variable pressures i.e. 4, 6, and  8 hours, for one hour.The  results revealed  that both  tisuk and  sukun were  satisfactorily treatable with CCB  solution  at 4 and  2 percent concentrations, respectively. For both CCB  treated   wood  species    used under roof and exposed to the open air without ground contact the recommended     pressures were 4 and 8 atmospheres. A schedule treatment 4 and 2 percent boron with 4 atmospheres pressure is respectively recommended  for tisuk and sukun used under roof without ground  contact.

Abstract

The aim of this experiment was to learn the properties/characteristics of activated charcoal manufacturedfrom various ligno­cellulosic materials, i.e. coconut shell, oil­palm bunches,  wood sawdust (sawn from mixed forest wood species), and empty oil­palm bunches.At first,  each  of the  four  ligno­cellulosic materials  was carbonized into charcoal  under the particular conditions, as follows : the  materials converted to small particles with 0.3 ­ 0.5  cm size, an  implementing carbonization temperature  at  500oC. The charcoal  was  activated  using  the condition:   activating temperature at 900oC for 30 minutes,  and exercising air flow  rate at 800 ­ I,100oC. The variables implemented in this experiment were kinds of raw materials (i.e.  4 kinds as previously mentioned), and soaking  in 1 percent  NaOH (alkali) for 24 hours which was further compared with the one without soaking.Charcoal properties showed that coconut shell obtained the highest in fixed carbon content,  the lowest in volatile matter and ash.  Results in activated charcoal analyses showed that  coconut shell obtained  the highest  in yield  (50.5%)  while the empty fruit bunch was the lowest (29.3%).  The coconut shell also  obtained the   highest  in fixed  carbon  (85.9%)  while the lowest was saw  dust (69.1%).Soaking treatment showed better quality on most of activated charcoal properties.   Coconut shell gave the highest in benzene adsorption (20.17%) and iod adsorption (881.8  mg/g).  In general,  other raw materials showed low adsorption to benzene, while most of them has been met the AWWA B.600 ­ 78 standard or iod adsorption. The CPO refining showed that  saw dust activated charcoal gave the best  in refining (54.8% transmission)  followed by empty fruit bunch, coconut shell and oil palm shell.
