Abstract
The most dominant palm oil mill effluent comes from processing inside the factory in the
form of empty fruit bunches (EFB), shells, fibers, mud and cake. In addition, solid waste
derived from the processing of liquid waste in the form of active sludge and ash derived
from burning EFB in incinerators. The raw materials used in this research are solid waste
of palm oil factories such as mud, ash, and palm fiber and organic waste from market as
additional carbon sources. The objective of this study was to learn the profile of
temperature, moisture content, and pH during the composting process of palm sludge on
variations of stack height 40 cm, 45 cm, and 50 cm of compost raw material. The result is
high stack 40 cm peak temperature reach 43,3 oC, stack height 45 cm peak temperature
reach 45,3 oC, and height of stack 50 cm peak temperature reached 47,3 oC. Temperature
profiles during composting for 21 days show the thermophilic phase of the composting
process has been achieved on a variation in compound heights of 45 cm and 50 cm, but at
40 cm heap altitude has not been reached. At the end of composting the measured pH was
between 7,2 - 7,5 and in accordance with SNI 19-7030-2004 for 3 variations of compost
pile. During the composting process the initial average moisture content ranges from 42.1
to 46.6% while at the end of composting the water content ranges from 39.3-43% for 3
variations of heap of compost raw material.Temperature, pH and humidity parameters
during the composting process at 3 variations of compost raw material pile indicate the
process works well.
