Abstract


The objectve of this research was to obtain the best materials composition and adhesive of organic pot for forest trees
seedling production. Organic pot strength was evaluated by testing the strength of rupture elasticity and elasticity stiffness
of each composition. The bioassay testing used Completely Randomized Design with factorial pattern, consisting of two
factors, (1) basic raw materials of the pot (used newspaper, litter and compost) and (2) the type of adhesive (control, tanin
and starch). The results showed that the adhesive starch gave higher strength, whereas adhesive tannin gave higher stiffness
as compared to control. Results of bioassay showed that the mixture (50:50 v/v) of basic materials of used newspaper and
compost (KKK) which were glued with tannin, produced the best results for height and diameter increament with the value
of 35.85 cm, 0.31 cm respectively and biomass value of 0.99 g after 12 weeks of planting. The highest level of damage in
organic pot with basic raw materials KKK without adhesive was 47.6%, whereas lowest level of damage in organic pot with
basic raw material used newspaper (KK) with tannin addhesive was 2.0% after 12 weeks in the nursery.
