Abstract
Solid waste of palm oil has increased along palm oil industry development in
Indonesia. Solid waste palm oil mill is organic pollutants. One of it is fiber waste,
if it not managed properly will pollute the environment. The purpose of this study
was to examine the effect of mixed cultures on process of aerobic composting of
palm fiber with windrow method. This research is treating three windrows with
size 6 x 1 x 0.5 m3 each one without the addition of a starter, with the addition of
starter and addition of starter and POME. The C/N ratio result of the research
showed that 19,91 on composting without starter at days 34, 19,73 on
composting with starter addition at days 32, and 16,93 at days 30 on composting
with addition of starter and POME. Optimum composting is windrow with additing
starter and POME. At this composting kinetic parameters are maximum growth
rate (μmaks), máximum substrat consumption constanta (Ks), and yield coeficient
(Y), continuously 0,73 day-1, 49,1 g/L, and 0,030.
