Sieving Effect of Sorting Machine with Vibration Table Type on Cacao Pod Based Compost
Abstract: Cacao pod is the
biggest part (70% of weight) of Cacao, which was not optimaly utilized.Cacao
pod is one of organic material that can be functioned as an organic fertilizer,
such as compost. When utilized with right proportion, organic fertilizer is
safe for plants and not degrades the soil composition. Composting process is
one of utilization form of Cacao pod. The size reduction of cacao pod in the
organic fertilizer process would help to accelerate the composting process.
Smaller particle size would faster interacting with environment, so the
composting process would be well accelerated if compared to the material with
bigger size. Chopping machine of Cacao pod is used to cut the biomass to be
small particle in order to be able to be utilized as some important necessity,
i.e. fertilizer or farm animals feed. However, Varies compost size was one of
the problems faced in the composting process. Therefore, the sorting process
was needed to be done after chopping process, so the compost size became
uniform and fulfll the user demand. This research was aimed at knowing the
slope effect of sorting machine and rotation speed (RPM). The method used in
analyzing the results of this research was comparing the treatment factors,
which are shown with histogram. As the super small size of compost recommended
for applying in the fertilizing process, so the optimum treatment combination
for having high mass fraction of SS compost grade was achieved at 12oslope of
sieve table and 1400 RPM motor rotation speed. As bigger the particle densities
of the compost size as smaller the compost porosity. Mass loss was very low at
all treatment combination with the value around 0.43-1.33%, so the sieving
effciency can be said very high.
