Abstract
Based on data from the United Nations Population Fund (UNFPA), the world^s human population in 2021 is 7,875 million. Meanwhile, the human population in Indonesia in 2021 is 276.4 million people. The more human population, the more waste generated. The Ministry of Environment and Forestry (KLHK) on its website states that the amount of national waste in 2020 is projected to be around 67.8 million tons and will continue to grow along with population growth. In order to avoid the accumulation of garbage which results in bins or trash cans being full and scattered, it is necessary to monitor waste by cleaning staff. Waste monitoring carried out by the cleaning staff at Kuntum Cemerlang School is still manual, so it takes a long time to check all the existing trash cans, as a result, it is too late to dispose of waste to the waste bank. One of the innovations that can speed up the monitoring process is to use ultrasonic sensors to determine the height of the waste from the smartphone. The ultrasonic sensor is connected to an arduino uno based on the Internet of Things (IoT) using the Blynk application service on an Android smartphone. The data from the ultrasonic sensor is transmitted to the Blynk application via the ESP8266 Wifi Module. This study uses electrical energy sources from Powerbanks, Solar Panels and Laptops. The height of the waste was made into three conditions, namely full condition (<7 cm), almost full condition (8-20 cm) and still empty condition (>20 cm). The level of suitability of the contents of the trash can with the output on the Blynk application from 30 trials in each condition is 98% valid. With this waste monitoring can be done faster than before.
