Abstract

Taungya farming system  has given peasants an opportunity to produce some food  without  getting  involved in forest planting  activities. It is not only  cheap, but also very  attractive to peoples around the  forest. This report was a result of data processing of  peasant's income  in  taungya   farming  system in Bojonegoro Forest District, East Java,   early in 1986.The total peasant's income consists of taungya farming income, other forest  activities  income,  and  income  of  non forest   activities.  Generaly,  the share of each  type  of income    to the average total  peasant's income per year is concecutively 36.8 % (Rp 57,381) of  taungya  farming income;  26.9 % (Rp 41,976) of  other  forest  activities  income  and  36.3.   % (Rp 56,473)  of  non  forest  activities  income.The proportion of  taungya  income to  total  income  of  lnmas peasants (55.8%) is higher  than  Non-Inmas  peasants (21.8%); whereas  peasants working on a low site  quality    have proportion of taungya income to total income, 12.3%, which is lower than those  working  on a  site  with  higher  quality (50.1%).In fact, peasant's income that resultfrom forest activities, especially taungya   farming  still  could  not  cope  withtheir  poverty.   Average   total  income   of  peasants is  Rp  50,814 per capita  in  a year or only 77 % of  the minimum living standard  cost  only.   Nevertheless,  the  average   total  income   of  peasants  had good  distribution,   as far as it is concerned  this would  not  cause an alarming  trouble   to  the  social   community.

Abstract

A research in production cost and its distribution was conducted in several plywood manufacturers in South Sumatra and South Kalimantan. The  average, distribution and  variation  of production cost  are discussed in this report. The  results  showed  that  average cost  of  production  was  Rp  313,066  per cu.m.  with  coefficient of  variation  9% consisting of  average  fixed cost  Rp 59,135 per cu.m.  with  coefficient of  variation  19%  and  average  variable  cost Rp 253,931 per cu.m.  with  coefficient   of  variation  12%. Average profit   before  taxes  was Rp 78,827 per  cu.m.  or 26% of production cost  with  coefficient  of  variation  48%.  Due to the fact  that  the largers component   of  the cost  was used for material  expense (56%) so  it is advised  the manufacturers  should  give more care the material processing  aspect  so that  the waste  could  be reduced  as small as possible.

Abstract

One  of planting  pattern   in reforestation   that  has proved   to  be successful   is  taungya   system.   The  advantage gained by  the  farmers  are especially  in the  fulfilment  of  food  need  in  the short  term.The average income of  farmers from taungya  system  in KPH Ciamis, Citanduy  catchment area, is I47.526,- rupiahs per year per share area (0.219I hectare) or 28.5% of  farmer  total  income.Variables that significantly influence the income from taungya system  (YI)  are production facility  expenditure (XI), labour  cost  (X2),  and share area (X6).  The  relationship  is shown   by  linear regression   model YI  =  154,4588 + l,2791 XI + I,8254 X2  +  0,0214 X6  (R2 =  0,8388).Farmers  income   level  from  taungya  system   has positively  influenced  the  main  plants.  The  regression  model   that shows  the  relationship   between  farmer  income  and  base plane  area is shown   by  the  equation Y2  =  0,3557 + 0,05I3 YI   (R2 = 0,6801) at  99%  confidence   level.

Abstract

Total area of Pine  forests at Perum Perhutani Unit I, Central Java, relatively    enlarges  each year,  but  its utilization for wood  and  resin  tapping  are only  60%. Pine  resin processing of collophonium commodity has yielded  65% in volume. This study  showed  a predictive model  of collophonium  production  at Central Java as Y  = -11,32+0,65X1**-0,43X2 +0,14X3*The  model  above  showed  that Pine resin volume  (X1) is highly  significant  and collophonium  price  (X3)  is significant to collophoniutn  production  (Y),  whereas  labour  variable  (X2) is not  significant because  the  ultilization of  labour is not efficient yet. The simple  regressions Y1 = 28,77 + 0,65 X1 and  Y2 = 1075  + 9,35  X3 are used  to explain  the relation  between Y and X1 or X2 individually.
