Abstract
Rice straw is the stem and leaves of rice as a field crop residues. Rice straw are
most widely available raw material for composting. However, decomposition of
rice straw take along time because of its high lignin content. These problem can
be overcome by manipulating the legth incubation of thermophilic phase during
composting. The present study was conducted to determine the effect of
manipulating the length incubation of thermophilic phase on rice straw and
market wastes composting on compost product. The study was conducted in two
stages. The first stage was done to evaluate bioactivactor microorganism
capability to degrade the raw material at thermophilic condition. It was set in a
randomized complete block design, three treatments for each raw material, i.e
J40: rice straw, incubation at 40°C; J45: rice straw, incubation at 45°C; J50: rice
straw, incubation at 50°C, and SP40: market wastes, incubation at 40°C; SP45:
market wastes, incubation at 45°C; SP50: market wastes, incubation at 50°C. The
second stage was set in a randomized complete block design, four treatments for
each raw material, i.e J0: rice straw composting, 0 week incubation of
thermophilic phase; J1: rice straw composting, 1 week incubation of thermophilic
phase; J2: rice straw composting, 2 weeks incubation of thermophilic phase; J3:
rice straw composting, 3 weeks incubation of thermophilic phase, and SP0:
market wastes composting, 0 week incubation of thermophilic phase; SP1: market
wastes composting, 1 week incubation of thermophilic phase SP2: market wastes
composting, 2 weeks incubation of thermophilic phase, and SP3: market wastes
composting, 3 weeks incubation of thermophilic phase. The parameter which was
observed in the first stage was C0
2
production, while on the 2nd stage were C, N,
C / N, pH, color, and amount of lignin-degraded. The results showed that the CO
2
production of J50 and SP50 treatments was the highest. Addition of incubation
time of thermophilic phase (50
0
C) during rice straw composting, reducing the
level of C and increasing the amount of lignin-degraded, but not affecting the C/N
ratio and pH, whereas in market wastes composting, these addition reducing the
level of C and C/N, increasing the amount of lignin-degraded, but not affecting
the pH.
Keywords: composting, termofil phase, rice straw, market waste
