Fallen leaves are often thrown away or burnt down after being collected. The trash cans become full in a short time. Meanwhile, electricity often blackout at night. Of course, it’s hard for people to do their daily activities such as studying, reading, etc. Two problems appeared; so many trash and the blackout, creating a trash cans might be one of solution.

Creating trash cans to produce electricity that consist of 2 plastic jars with different size, the smaller one is put inside,and the bigger one outside. Put a metal that consist of copper plat and aluminum plat and both electrode don’t touch each other. Connect the upper part of metal electrode with a cable to a different metal electrode. And also Connect both cable ends to LED leg. In order to turn on the LED, insert fallen leaves to the small jar until full. Pour water to the leaves until all the small glasses are full.

The result is the trash cans, can produce voltage from leaves water in six plastic glasses in 3,28 volt. With that voltage, the Trash cans, can turn on 7 LED. With this trash can, the leaves can be used as an alternative energy source.

It had been socialized about Electricity Generator Trash Cans in front of Al-Jannah teachers on April 25th,2018. The result of that activity is the teachers' understanding about fallen leaves that are always happen has been changed, fallen leaves can be used as electric energy source.
