Abstract

We often find food waste daily, especially on household and restaurant
scales. Using food waste for helpful something, biogas is an alternative
to reduce wasted waste and produce renewable energy. The anaerobic
digestion process is a process that decomposes organic material into
biogas with the help of microorganisms in conditions without oxygen.
Adding nutrients in the anaerobic digestion process can positively affect
biogas-producing microorganisms. One of the nutrients or nutrients
studied this time is Ca and K. The provision of nutrient Ca has a
positive effect, namely a significant increase in biogas production
compared to without the addition of nutrients. However, adding K does
not positively impact biogas production is inhibited. Excessive amounts
of nutrient K can inhibit the process by inhibiting microorganisms in
breaking down intermediate products into biogas. The largest volume of
biogas produced for five days came from the reactor with the addition
of nutrient Ca, which was 15072 cm3
, while the control reactor and
reactor with the addition of nutrient K produced biogas of 1648.5 cm3
and 15.7 cm3
. The addition of nutrient Ca increases biogas production
more than nine times.
