Abstract

Oyster  mushroom   (Pleurotus ostreatus) was cultivated  on sawdust  of  four  wood  species,   i.e.  teak  (Tectona  grandis L.f.), rubber   (Hevea  brasiliensis  .Muell.   Arg.),    kemang  (Mangifera  caesia  Jack)  and  meranti   merah  (Shorea  johorensis Foxw.)   mixed   with  rice  bran containing  5 %, 10 %, 15 %, 20 %, 25 % by  weight  and  distilled  water, The  substrate  was cooled  after  autoclave  sterilization   before  being inoculated  with  pure  culture  of oyster  mushroom. The mature  mushrooms were harvested  daily  after   the growth  of  fruiting  body.Relative   high  yield   was obtained   from   rubber  (146.92 g) and  kemang  (122.77 g),  the lower  yield  was obtained from  teak  (73.84 g) and the lowest  from  meranti  merah (58.82   g) per 500 g media.     .Rice  bran supplement seems  to improve mushroom yield. The  lowest  yield  i.e;  obtained   from  sawdust  substrate mixed  with  5 % rice bran  (65.78 g).  Rice bran supplementation  of 10 -  25 % gave non significant  different  yield  (80.30  - 88.86   g) per  500 g media.The  average Biological  Efficiency (BE)  of entire  treatments   were  obtained  from  rubber  64.27 % (45.24  - 79.84 %) and  kemang 61.66  % (56.84  - 74.25 %).  The  lower  BE  was obtained  from  teak 29.53  % (25.86 - 33.92  %) and meranti merah  24.70 % (0 -  40.22 %).

Abstract

Khaya anthotheca  C.DC. is  one  of  exotic tree  species  selected   for   trial planting   in  Indonesia   by  the  Forest Research  Institute,   about  25 years  ago.This  paper discusses   the   result  of  a   laboratory   study   on   the  variation  of  wood   moisture content and  air dry specific   gravity   within   and  between  trees,  the  effects   of  height   from   the  ground  and  distance   from  pith   outward   on these  two  properties.   The  material for the  study   consisted   of  three  20  year  old  trees  of  Khaya  anthotheca  C.DC.  with  diameters   at breast  height  ranging from  38 - 41 cm, height  (until  top)  15 - I 7 m and clear bole length  from 9 -  9.5  meters.  The  trees were   felled  on plantation  site  at Cikole  (North  of  Bandung)   on  the  slope  of Mount Tangkuban  Perahu,  and  transported to  Bogor  for  laboratory testing.The  result  of  statistical   analyses  reveal,  non  significant   differences between trees  and  bolts  within   trees  for  air dry  specific  gravity,  and significant  difference   in the property   from  pith  outward.The  green   (fresh)  moisture  contents   on  the  other  hand  between   bolts  and  distance   from  pith  are significantly different. Regressions  relating the two properties  (air dry specific  gravity  and moisture  content)  as dependent variables with respective distance from pith   outward   being  1/3, 2/3, and  3/3  of the  radius,  and height  of  bolt  0.2, 2.7, 5.2, and 7.7 meters  above  the ground  as independent variables show  the following  :(1).S  =  0.436  -  0.017Z  +  0.003 Z2                                       =  (R=0.536)                       (Z =Height,   S =Specific gravity)(2).A =  99.98  -   3.591Z  + 0.224 Z2                                        = (R=0.466)                    (Z = Height,  A  = Moisture  content)(3).S =  0.396  + 0.018   X  + 0.044X2                                      =  (R=0.510) (4).A=  86.79  -   1.495  x   + 4.25X2                                         =  (R=0.101)               (X = distance  from  pith  outward)Test  of  significance  of  the  regression coeficient   (Table  4)  indicate  significant  F values for  the  first  two  equations (effect  of height)  and non significant  results for  the last two equations (effect  of distance  from pith).

Abstract

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.

Abstract

Compared   to  Santalum   album  L.,  the  wood  of  Exocarpus Latifolia R.Br. is lower  in quality.  It  is there necessary  to investigate   the  difference   of  their  wood  features   to overcome   the  unwanted   substitution or fraud possibilities.Microscopic  study  reveals that  there  are many  similarities  in wood  anatomy   between   Santalum album  L.  and Exocarpus  latifolia R. Br. They are anatomically different   only  in pore  diameter  and pore  frequency. The wood  of  Exocarpus latifolia R.Br.  has larger pore  diameter   but  lower pore  frequency. Some   differences   were  also  ob1erved  on  gross  features   of  wood.   Exocarpus latifolia   R. Br.  has  darker  sapwood color,  coarser wood  texture  and  less aromatic odour.

Abstract

A  laboratory  experiment    on  biogas generation  using solid  waste  in a  batch  culture  under  Thermophillic condition was conducted at the Forest Products Research  and  Development  Centre, Bogor.The solid  waste used in the experiment were rice straw, water hyacinth (Eichornia  crassipes Mart.  Solms)  and rubber wood  (Hevea  braziliensis)  sawdust.Fermentation   condition   for  biogas production   was kept  constant  under  temperature  of 53°C  for 8 days.  Inoculumn used for  fermentation  was  residue from the experiment of  organic municipal solid  waste fermentation.The raw material used in this experiment consisted  of mixture  of  73 gram rice straw and 27 gram water, 70 gram rice straw and  30 gram  water  hyacinth, 38 gram rubber  wood  sawdust  and  62 gram water,  36,25  gram rubber wood  sawdust and  63,75 water hyacinth. To each mixture   was added  900 gram  of  starter  with  dry  matter  content  28%. Each substrate sample   was  then  placed   in  a  1,5 littre  digester.The  result  of  the  experiment   indicates  that  the highest  production   of biogas and methane  were produced   from  rice straw  substrate (0,43  littre  of biogas and 0,21 littre of methane  per gram of straw respectively),  and the efficiency   of biogas produced  was 75%.The   total   calorific value of   biogas   produced was  lower  than   that  obtained   from  direct burning  of  rice straw.  Although    the  calorific  value   of   biogas   is  relatively  low, its  burning  quality is better compared   with direct  burning. Besides that, the residue from  fermentation   process  could  be utilized  as organic fertilizer  and mushroom  media.
