TINJAUAN NERACA MASSA PADA PROSES PENGOMPOSAN TANDAN KOSONG KELAPA SAWIT DENGAN PENAMBAHAN AIR LIMBAH PABRIK KELAPA SAWIT
ABSTRACT: The waste generated
from oil palm mills in the form of empty fruit bunches (EFB) and palm oil mill
effluent (POME) can be used utilized to be processed into compost, which is
beneficial for treating waste from palm oil mills as well as generate organic
fertilizer that can be applied to land.
The research was conducted to determine the mass balance in the form of
input and output during the compost production process and carried out in a
pilot scale in order to give an idea if composting is done on a large
scale. This research aimed to analyze
the mass balance of composting process of EFB and POME and calculate C/N ratio
of EFB and compost, respectively. The
research was conducted in a descriptive experimental method and data were
presented in tables and graphs. The
composting is carried out in two replications and without treatment. The composting was carried out for 54
days, during the research, temperature,
pH and water content were monitored. The
results showed that the maximum temperature during the composting process were
49.9 to 50.90 °C, the pH value were 6.85 to 7.94, the water content during were
76.81 to 77.88%. Overall, the input as
EFB and POME were 34.91 to 37.33% and POME 62.67 to 65.09%, respectively. The Output in form of leachate and compost
were about 27.02 to 27.58%, and 24.04 to 26.09%, respectively, and evaporated materials
were about 46.33 to 48.94%. For
composing, 1.0 ton EFB required POME about 1.57 to 1.74 m3, produced compost
about 688.62 to 698.85 kg, leachate about 0.724 to 0.758 m3 (density = 1.02
kg/dm3), and evaporated material about 1241.26 to 1401.95 Kg. The C/N ratio on EFB was 28.86 and C/N ratio
of the compost was 8.91.
