ABSTRACT
Background and Aim: Composting method is one way of managing organic waste that can be done from the source, namely the household. Using a composter bins is designed to make it easier to handle household waste. The size of the compost raw material will affect the compost maturation time. The smaller the size of the waste, the faster the harvest period. Most of the studies that have been carried out, the design of a composter with a manual chopper can be a solution to facilitate household scale composting. This study aims to design and test the performance of a compost container equipped with a manual chopper namely “Tongposcah”.
Method: The design of the composter tool is done by sketching the image using the Autocad application. The design is then carried out by assembling the tool. The assembled composer was then tested. The trial was carried out with parameter monitoring. The parameters observed included the size of the chopped particles, the capacity of organic waste and the length of time for chopping. The trial was conducted to determine the ability of the composter designed to carry out the composting process. After the trial is complete, the next tool evaluation analysis is carried out.
Results: The size of the composter bin has a height of 100 cm, a diameter of 45 cm with a volume of 150 L which is equipped with a manual chopper mounted on the top of the container. The results of experiments in the composter performance is the composter able to produce 22,735 kg in one process with a processing time of 75 minutes until the bin is full. The time is influenced by the ability of human power because the tool is rotated manually. The composter is able to accommodate a total of 75 L of compost material, 30 L of leachate, this is due to the bulkhead in the equipment and leachate filtration.
Conclusion: Overview mechanically Tongposcah is able to accommodate a maximum of 15-60 kg of household waste, the stirrer system can rotate stably, the mixing of organic waste compost material has been stable (homogeneous), the air ventilation system as a temperature regulation can work well, the entrance and exit of compost material at the composter works well, the composter legs are sturdy and strong against rotational vibrations, the composter chopper drive lever through the rotating wheel can rotate well, the composter can hold liquid compost from leakage.
