Garbage is often a problem, especially in big cities. The average amount of waste in Indonesia
is 64 million tons / year, while the number of landfills in Indonesia is around 400 with a landfill capacity
that can accommodate 233 kg / day. Not to mention the unpleasant odor and dirty city views cause
discomfort. This is where a solution is needed by leading to the use of technology in an effort to
create a clean environment by reducing the level of waste accumulation and reducing waste littered
with the Internet of Things technology. This tool is able to monitor the height of waste and gas content
via the web. The internet system uses the MCU Node module with energy supply from solar cells.
Working voltage of the control system is 5V, a stepdown module is needed to reduce the battery
voltage from 12V to 5V. Detection of the height of waste using a PING sensor and to determine the
levels of methane gas using the sensor MQ-135. From testing at Student Center LT 4, it was found
that the garbage accumulated on Saturday by 60 cm with 126 PPM methane gas levels that indicated
unhealthy. This monitoring system can last up to 7 days because it uses solar cells, but this can
experience changes due to the intensity of the sun.
