Abstract

Timber harvesting activities in Perhutani areas are conducted  with the involvement of people living around the forest.  An  investigation was conducted  to find  out the role of timber harvesting activities  in increasing the income of people involved. The results showed that 1) People living around the forest were involved in felling, skidding, and collecting  log in temporary logyard; 2) Workers involvement were temporary and their wage system were differed from location to location. In Sukabumi,  the whole work contract system was applied with the income ranging from Rp 109.800 to  187.417/person/compartment or  Rp  13.725  to Rp 23.500/person/day.  In Cianjur,  the piece  work system was applied with income ranging from Rp 97.788 to 179.166/person/compartment   or Rp 5.750 to Rp 10.500/person/day; and 3) The income obtained from  timber harvesting activities still can not significantly  increase worker's income and, therefore, it is necessary to furthur seek a proper model suitable for the need of temporary and low income workers to participate in managing forest  in Perhutani areas.

Abstract

Loading  and unloading works are intermediary activities in the logging operation.  The logs after being felled/cut down in the forest will be of economic values when they cannot be brought to the inherent processing industrie. Light­weight and small­size logs favor manual work in their handling as  long  as  man power  is available. Heavy­weight and  large­size  logs, however,  necessitate an auxiliary heavy­duty equipment,  since the manual work is sometimes no longer effective for loading­related operation, e.g. hoisting, placing, regulating their position, etc. The unloading of such logs, conversely, turns out to be easier, but can pose a dangerous threat. Therefore, cautious care is necessary.In dealing with loading/unloading problems as such particularly in plantation forest,  a special equipment that is simple in design has been devised, called as Exp­2000. The equipment, wich is powered by 11­HP's diesel engine, can also perform the skidding­operation.  The overall cost in devising the Exp­2000 's equipment  was Rp. 50,000,000. The trial test as performed on the equipment revealed the following results:                                                                     .The average loading and loading productivities were consecutively 9.54 m3 per hour and  13.18 m3 per hour.Cost of loading as well as unloading was Rp. 1.597,48 per m3.The average skidding productivity was 0.5053 m3.hm/hour with skidding cost at Rp 30,160 per m3.The skidding cost might be reduced to Rp.  21,165 per  m3  and concurrently the productivity increased to 2.25 m3per hour,  if the more powerful diesel engine,  e.g.  25 HP were used.
