POTENSI TRICHODERMA ISOLAT LOKAL SEBAGAI DEKOMPOSER SERASAH AKASIA (Acacia mangium)
ABSTRACT: Acacia produce a
litter of in the forest industry plants are not utilized and difficult to
decompose so it can be acumulotion of litter. The decomposition can be
accelarared with the use of localTrichoderma isolates. But, it is not yet known
the best local isolates and concentration oftrichoderma as the decomposers of
acacia litter. The aim of research to get the kind of localisolate and
concentrate the best Trichoderma as decomposers of litter acacia. This research
was conducted at the Laboratory of Silviculture Forestry University Tanjungpura
Pontianak for 8 months starting from the preparation, execution, analisis this
research method is done in the form of factorial experimental design completely
randomized experimental with design. The treatments consisted of two factors,
namely the local isolates of Trichoderma (Trichoderma sp.1 = T1; Trichoderma
sp. 2 = T2; Trichoderma sp. 3 = T3, Trichoderma sp. 4 = 4) and theconcentration
of Trichoderma suspension (10-5 ml = k1, 10-6 ml = k2, 10-7 = k3). Thecombination
total of treatments were 12 units with three replications. The observed data is
decomposed pH value before and after decomposed, the mycelium dry weight, the
percentage ofmoisture litter, the C / N ratio and the content of phosphor (P)
and potassium (K). Based on the results turned out to isolate Trichoderma sp 2
with a concentration of 10-5 is the best decomposers to accelerate proser
acacia mangium litter decomposition. Time or the length ofthe decomposition can
be extended for more or less five months to get maximum results.
