Abstract

Regrowth forests in Indonesia have eesentially been developed since several centuries ago particularly in Java for the luxury timber species such as teak (Tectona grandis), rasamala (Altingia excelsea), Sonokeling (Dalbergia latifolia), mahoni (Swietenia spp.), etc. In this system the young plantation always have surplus trees which are likely to cause overcrowding and furthermore reducing the growth of bigger trees. Accordingly, at certain ages (depending on species, site class, etc.) the surplus trees are thinned out regularly throughout the planting cycle to achieve a maximum timber yield. Each thinning will produce a plenty of small-sized logs which are generally considered too small for sawmills or plymills. Such logs are commonly used for firewood or other low value products, or even left to rot in the forest floor.This study investigated a technical possibility of turning the waste wood into useful interior products, such as table top, furniture blanks, window and door frames, etc. Thinned logs of two wood species, tusam (Pinus merkusii) and damar (Agathis lorantifolia) collected from a government company plantation in West Java were used in this study. Procedures of saving logs into boards, drying and further machining processes were basically undertaken according to the convetional practices. Furniture blanks, table tops and large planks were manufactured by side-jointing and or laminating thin boards with a simple clamping procedures. Polyvinyl acetate and resorcinol formaldehyde adhesives were uesd for constructing blanks and planks respectively. The results revealed thar interior products made up from the thinned logs possessed a comparable characteristics to those made from mature timbers. Table tops and blanks built from three layers of laminates gave a better concictency in shape and straightness than the one layer side joint panels.

Abstract

This paper discribes the study of the use of Colt diesel 100 PS truck for seedling transportation in timber estate establishment carried out at one timber estate company in South Sumatera in 1991. The objective is to find out the information about the use of Colt Diesel 100 PS truck for seedling transportation. Data on productivity and cost of Colt Diesel 100 PS truck as weel as hauling distance and labor’s wages were collected. The study results are as follows :Colt Diesel 100 PS truck is appropriate for transporting seedling from plantation in timber estate area. To make loading and un;oading easy and to avoid the damage of seedling during transportation activity, the seedling should be put into strong wood boxes.Colt Diesel 100 PS truck can be loaded with 20 to 21 seedling boxes consisting of 1,200 to 1,260 seedlings. The productivity of Colt Diesel 100 PS truck for seedling transportation varied from 8,675 to 13,340 seedling-km/hour with an average of 10,944 seedling-km/hour.Cost of Colt Diesel 100 PS truck per seedling ranged between Rp. 3.20 and Rp 4.84/seedling-km with an average of Rp 3.87/seedling-km.To make seedling transportation activity runs well, it is suggested that forest roads be paved so that they can be used at all weather conditions.

Abstract

Plywood industry (wood based industry) is a suitable accupation  field  for woman labor, where woman can participate in forestry development.                                                                The  aim  of  the  study  is  to  evaluate participation of  woman  labor  at plywood  industry  by  observing  their  activities from demographical, social and economical aspects.This  study  was  conducted  by  collecting  data from  plywood  companies, Provincial    Forestry  Office,  Statistics  Office,  and interviewing 10 percent of woman and man labors from plywood companies in East Kalimantan province.The results show that about 74 percent of production  labor is woman, and most of them work in all sections such as veneer matching and splicing, gluing, pressing,  and finishing. About 70 percent of woman labor is unmarried, average age is 24 years  with high school education, so they have adequate capacity to work.  About 60 percent comes from  out of East Kalimantan province. It shows that woman labor at plywood  industry has high motivation and mobility to  work.  Generally, they live in a rent house  with minimum condition for their welfare.  They usually do not have much time left to participate in social activities commonly organized in surrounding living area.Basic salary of woman labor working for normal shift is  Rp.  2,500 and for long shift is Rp. 3,300 per day.  It means higher than Minimum Regional Salary determined by  goverment office. Woman labor gross income working for normal shift is Rp.  135,000 per month in average  or more   than Minimum Physical Need of unmarried labor that is only Rp. 86.930,-. While the gross income for those working for  long shift is Rp.  242,500 per month or more than Minimum Physical Need  for one family consisting of a pair of parents having a child which is only Rp.200,685,-. In conclusion, woman labor  income can give a

Abstract

Being concerned with forest resources sustainability due to its extraction speed, Indonesia government tried to restrict forest products export by export bans during 1970s until the midle of 1980s, and by raising of export taxes since the end of 1980s.Export tax is one of government revenue sources. Indonesia government revenue from export tax is relatively small, it only accounts for 0,04% of the total government revenue , or 0,07% of the total revenue out of oil and gas.The more the development of the country, the higher thr governmnet’s revenue from income tax, firm tax, wage tax, and value added tax, and the more the government’s dependency on domestic sources. On the other hand, presently export tax revenue is relatively low. Indonesia government revenue from export tax is important, because the revenue from other taxes is small relatively.The higher the export tax rate, it will impose more restriction of forest products export flow. Statistically, at 99% confidence level, the increase of sawn timber export tax at the end of 1989 has given significant influence on the decrease of sawn timber export volume. Taxation policy is an effective instrument for allocation of forest product resources.Forest product export ban is one of non-tariff barrier, in which repleased by export tax policy is in accordance with GATT agreement. Levying of forest product export tax is a real measures of Indonesia government in executing sustainable development. As a tariff barier, axercising forest product export tax is a real measures of Indonesia government in executing sustainable development. As a tariff barier, exercising forest product export tax is not contrary to the consensus in international trading order.

Abstract

Five wood species originated from Jambi were observed for their machining properties in this study.    Sawing characteristics (feed speed and surface smoothness) of each species were observed to determine  its cutting-ability.  Sawn timbers were then cut to sample boards and air-seasoned to approximately 17% moisture content prior to further machining processes. The examined machining properties include planing, shaping,  boring,  turning and sanding.  Examinations were  undergone according 10 the modified ASTM D-1666 as firstly described in the Forest Products Research Institute Report No.  160 (1982).Results from this study showed that most of the species could be sawn at medium feed speed  with a variation in cutting surface quality, ranging from fair  to rough.   One species, i.e., rengas pantai (Gluta renghas) is fairly difficult  to saw for  its irregular (partly interlocked) grain orientation and the abundant deposition of silica (crystals) in its fiber  structures.   Some species consistently showed good qualities in almost all machining tests, and likely produced excel/en/ surface quality when worked on using sharp culling tools and controlled machining condition.   Wood samples tested in wet condition produced a fairly good planing and shaping quality for most wood species. In  comparison, however, the air-dried samples significantly revealed a better machining quality. Based on the machining characteristics observed on the five wood species from Jambi, it is recommend able to use rengas tembaga, sumpung and rengas manuk for wood working purposes. Whereas, rengas pantai and kempas are more suitably intended   for indoor structural uses.

Abstract

 Freshly cut logs of tusam (Pinus  merkusii) are very susceptible to the infestation of the ambrosia beetle Xyleborus sp.  and blue stain fungi. An observation showed that both wood deteriorating organisms might infest a same log simultaneously, but they did not inhabit the same area. They have their own area which are separated from one to another. There is an indication that any parts of logs having been infested by the fungi will not be suitable any more for  the beetle's host.  It seems that the ambrosia beetle is deterred or repelled by the presence of the blue stain fungi  infestation, or at least,  the beetle responds unfavorably to the  fungi.
