Regrowth  forests in Indonesia have  essentially been developed since several centuries  ago particularly  in  Java for   the luxury timber species such as teak (fectona  grandis),  rasamala (Altingia excelsa), sonokeling (Dalbergia latifolia), mahoni  (swietenia spp.), etc.  in this system the young plantalions  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 lo achieve a maximum timber  yield.   Each thinning will produce a plenty of small-sized logs which are generally considered loo 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, furnilure blanks,  window and door frames,  etc.   Thinned  logs  of  two  wood  species,  tusam (Pinus merkusii) and damar  (Agathis lorantifolia) collected from  a governmen   company plantation  in  West  Java   were used in this study.    Procedures  of sawing logs into boards, drying and further machining processes  were  basically undertaken  according  lo the convenuonal  practices.   Furniture blanks, table tops  and large planks  were  manefactured  by  side-jointing  and  or  laminating  thin  boards  with  a  simple  clamping  procedures. Polyvinyl acetate and resorcinoi formaldehyde  adhesives  were used for constructing  blanks  and planks  respecliveiy.    The results revealed tha  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 consistency in shape and straightness  than the one layer  side joint panels.
