| Summary: | Composting is a biological treatment process to
treat organic waste. There are many parameters that affecting it
process. Temperature, pH, aeration, moisture content and
microorganism are a few factors controlling composting process.
Missing one of the parameter will result in incomplete process.
Thus, the objective of this study is to improving composting
process by controlling one parameter of composting which is
aeration. Before starting the composting process, the food wastes
are spread on a canvas to drain out excess water. After that, the
food wastes are grinded and let out to rest about 1 day under
sunlight. 12 kg of grinded and dried food waste was thrown into
composting bin and the first data was recorded. The food waste
in the composting bin has been rotated for 15 minutes and let to
rest another 15 minutes. The data collection has been done for
the total 53 hours in 3 days. Range for compost temperature,
compost pH, surrounding temperature and surrounding relative
humidity during the process are 26°C - 45°C, 4.24 – 5.81, 26.4°C
– 35.2°C, and 54% - 81%, respectively. Results show that with
the constant aeration time, time taken for composting process to
complete become shorter. Further research can be done to
compare various aeration times for composting. Thus, we can
come out with the standard of aeration of composting process.
This will enhance the composting process technique that help to
solve the problem of increasing food waste and prolong the
landfill lifetime. |
