Harianjogja.com, JOGJA-The increase in the population and changes in the lifestyle of the Indonesian people have resulted in a lot of food waste. The amount of waste in the Final Processing Site (TPA) is also increasing. The presence of food waste should not be a cause of environmental damage.
Referring to these problems, then through the Student Creativity Program in the field of Karsa Cipta, a group of students from the Islamic University of Indonesia (UII) offered a new innovation in the form of a Smart Machine for Recycling and Composting Food Waste named EFFAST (Electric Composting Food Waste) as a technology for processing food waste. in restaurants to overcome the negative impact of the large amount of food waste generated in the landfill. This technology works with the concept of drying through hot media and utilizing the results of processing to be used as organic fertilizer for plants.
The three students involved in the research conducted in July-August 2021 are Gayuh Ajeng Wandansari (Environmental Engineering/Faculty of Civil Engineering and Planning), Nurul Muzayyanah (Environmental Engineering/Faculty of Civil Engineering and Planning), and Ahmad Afifudin Noviantoro (Industrial Engineering/Faculty of Planning). Industrial Technology). They raised the title “Smart Machine for Recycling and Composting Food Waste Product name: EFFAST (Electric Composting Food Waste)” and was guided by lecturer Rininta Hanum, STTMeng.
Gayuh Ajeng Wandansari explained that the presence of EFFAST can be an alternative solution for the community, especially restaurant owners, to reduce food waste or organic waste that will go to the landfill. “In order not to cause environmental problems such as explosions in waste generation caused by the large amount of methane gas and the depletion of the ozone layer,” he said.
The working mechanism of the tool in the form of a processing process begins with soft-textured food waste that is inserted into the machine. Garbage is chopped with a chopping motor according to the signal sent by the Arduino Mega micro controller. The chopping process serves to expand the surface of the material so that it can speed up the drying process.
“The waste is then heated using a heater. The waste becomes fertilizer with factors that influence it, namely the density of the waste, temperature, humidity, and processing time,” said Nurul Muzayyanah.
The group drew two conclusions from this program. First, EFFAST as a technology for processing food waste with the concept of drying through hot media and utilizing the results of the processing to be used as organic fertilizer for plants. “Secondly, EFFAST is one of the innovative solutions for household-scale food waste processing technology as an effort to reduce waste generation at the TPA,” said Ahmad Afifudin Noviantoro.
